Technical Field

[0001] The present application relates to, but is not limited to, the technical field of automobile parts assembly, and in particular to an assembly device. Background Art

[0002] With the development of the automobile industry, automobile models have become more diversified, resulting in the diversification of front hood assemblies assembled on the vehicle bodies.

[0003] In the automobile production process, the assembly of the front cover assembly on the body-in-white assembly line is usually carried out at the same station or at different stations using special tooling.

[0004] If the front hood assemblies of different models are installed at the same workstation, multiple sets of tooling need to be placed on site to accommodate the front hood assemblies of different models, resulting in insufficient space for storing tooling on site; if the front hood assemblies of different models are installed at different workstations, the length of the assembly and adjustment line needs to be increased, resulting in a waste of installation space.

When installing the front cover assemblies of different models on the body-in-white assembly line, it is only necessary to select the positioning mechanism of the front cover assembly of the corresponding model, and make the corresponding positioning mechanism of the front cover assembly of the corresponding model in the positioning state, so as to achieve the purpose of positioning the front cover assembly of the corresponding model.

[0035] Reference Figure 1 The automobile includes a front hood assembly 2 and a body frame 1, wherein the front hood assembly 2 is assembled on the body frame 1, wherein the front hood assembly 2 can also be called an engine hood, and the front hood assembly 2 is a relatively independent assembly in the automobile body structure, and is a necessary passage for users to inspect and repair the powertrain system.

[0036] With the development of the automobile industry, automobile models have become more diversified. For example, the automobile in the embodiment of the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models, resulting in the front cover assembly 2 mounted on the vehicle body also becoming diversified.

[0037] The assembly of the front hood assembly 2 is generally completed on the body-in-white assembly line, wherein the body-in-white (BW) refers to the body that has been welded but not yet painted according to the body terminology standard and the definition in the textbook. The painted body-in-white is added with interior and exterior decorations, such as the instrument panel, seats, windshield, carpet, interior trim, etc.; and electronic and electrical systems, such as audio, wiring harness, switches, etc.; plus the chassis system, such as the braking system, suspension system, etc., plus the powertrain system, such as the engine, gearbox, etc., to form a complete vehicle.

[0038] It should be noted that, since the front cover assembly 2 is a relatively independent assembly in the automobile body structure and is a necessary passage for users to inspect and repair the power system, the front cover assembly 2 is movable relative to the body frame 1. It should be explained here that the front cover assembly 2 is rotatably connected relative to the body frame 1, and the rotatable connection can save a certain amount of displacement. When the user inspects and repairs the power assembly system, it is only necessary to apply an external force to move the front cover assembly 2 away from the side fixed relative to the body to complete the opening and closing of the front cover assembly 2, which is convenient for operation. In one possible implementation of the present application, the front cover assembly 2 and the body frame 1 can be assembled through a hinge nut.

[0039] Reference Figure 1 The present application provides an assembly device 3, which is used to assemble the front cover assembly 2 on the vehicle body frame 1. Here, the assembly device 3 can be set as one or more; the assembly device 3 can be set along the length direction of the front cover assembly 2, or along the width direction of the front cover assembly 2; of course, the assembly device 3 can also be symmetrically set along the width direction of the front cover assembly 2 in the length direction of the front cover assembly 2, and the present application does not limit this. In one possible implementation of the present application, the assembly device 3 is set in the length direction of the front cover assembly 2.

[0040] Reference Figure 1The assembly device 3 provided in the embodiment of the present application includes a base 31 and a plurality of positioning mechanisms 32, wherein the plurality of positioning mechanisms 32 are respectively connected to the base 31, and each positioning mechanism 32 is used to respectively position a different front cover assembly 2, and each positioning mechanism 32 can switch between a positioning state and an avoidance state, wherein when the positioning mechanism 32 is in the positioning state, it can position the front cover assembly 2 in the position to be positioned, and when the positioning mechanism 32 is in the avoidance state, it can avoid the front cover assembly 2 in the position to be assembled. Figure 2 , which is a schematic diagram of the structure of the front cover assembly 2 of the vehicle type A in which one of the positioning mechanisms 32 is positioned, referring to Figure 3 , which is a structural schematic diagram of one of the positioning mechanisms 32 positioning the front cover assembly 2 of vehicle type B.

[0041] Among them, each positioning mechanism 32 is connected to the base 31 respectively, and each positioning mechanism 32 is used to position different front cover assemblies 2 respectively, and each positioning mechanism 32 can switch between the positioning state and the avoidance state, wherein, when the positioning mechanism 32 is in the positioning state, it can position the front cover assembly 2 in the position to be positioned, and when the positioning mechanism 32 is in the avoidance state, it can avoid the front cover assembly 2 in the position to be assembled. When the front cover assemblies 2 of different models are installed on the body-in-white assembly line, and the corresponding positioning mechanism of the front cover assembly 2 of the corresponding model is in the positioning state, the purpose of positioning the front cover assembly 2 of the corresponding model can be achieved. Compared with the related art, it is necessary to place multiple sets of tooling on site to adapt to the front cover assemblies 2 of different models, which makes the space for storing tooling on site insufficient. In this application, only one set of tooling is placed on site, and multiple positioning mechanisms 32 are set in the positioning mechanism 32 of one set of tooling. When each positioning mechanism 32 is in the positioning state, it can position different front cover assemblies 2, saving the space for storing tooling on site. Compared with the related art, if different workstations are used to install different models, the length of the assembly line needs to be increased, resulting in a waste of installation space. In this application, the front cover assembly 2 of different models can be installed at the same workstation without increasing the length of the assembly line, thus avoiding a waste of installation space. That is, the assembly device 3 provided by this application can adapt to the installation of the front cover assembly 2 of different models, saving the installation space of the front cover assembly 2 on the body-in-white assembly line.

[0042] Among them, when the positioning mechanism 32 is in the positioning state, it can position the front cover assembly 2 at the position to be positioned, and when the positioning mechanism 32 is in the avoidance state, it can avoid the front cover assembly 2 at the position to be assembled. It should be supplemented here that when one of the positioning mechanisms 32 is in the positioning state, the other positioning mechanisms 32 are in the avoidance state, and the other positioning mechanisms 32 cannot affect the front cover assembly 2 at the position to be assembled, nor can they affect the front cover assembly 2 at the position to be positioned. In short, when the other positioning mechanisms 32 are in the avoidance state, they cannot affect the normal operation of the positioning mechanism 32 that is positioning the front cover assembly 2 at the position to be positioned, nor can they affect the normal operation of the body-in-white assembly production line.

[0043] In addition, a plurality of positioning mechanisms 32 are respectively connected to the base 31, and each positioning mechanism 32 is used to respectively position a different front cover assembly 2. In one possible implementation of the present application, there are two positioning mechanisms 32, and the two positioning mechanisms 32 are respectively used to position two types of front cover assemblies 2, namely, the front cover assembly 2 of model A and the front cover assembly 2 of model B.

[0044] Reference Figure 1 and Figure 4 Since each positioning mechanism 32 is used to position a different front cover assembly 2 respectively, after the hinge nut of the front cover assembly 2 is manually tightened, the multiple positioning mechanisms 32 need to be removed from the front cover assembly 2 assembled on the vehicle body frame 1. For this reason, in an implementable method of the present application, a pushing mechanism 33 is also provided on the base 31, and the pushing mechanism 33 includes a pushing portion 331, and the pushing portion 331 moves relative to the base 31 to push the front cover assembly 2 away from the multiple positioning mechanisms 32.

[0045] The pushing mechanism 33 includes a pushing portion 331, which can move relative to the base 31 to push the front cover assembly 2 out of the multiple positioning mechanisms 32. The pushing portion 331 can move in the horizontal direction of the base 31 to push the front cover assembly 2 out of the multiple positioning mechanisms 32, and the pushing portion 331 can also move in the vertical direction of the base 31 to push the front cover assembly 2 out of the multiple positioning mechanisms 32. The present application does not limit this. In one possible implementation of the present application, the pushing portion 331 moves in the vertical direction of the base 31 to push the front cover assembly 2 out of the multiple positioning mechanisms 32.

[0046] For example, the push part 331 moves along the vertical direction of the base 31 to push the front cover assembly 2 out of the multiple positioning mechanisms 32. The push part 331 can perform translational movement along the vertical direction of the base 31 or rotational movement along the vertical direction of the base 31. This application does not limit this. Compared with the translational movement of the push part 331 along the vertical direction of the base 31, the rotational movement along the vertical direction of the base 31 saves more movement space and movement displacement. Therefore, in one possible implementation of the application, the push part 331 can rotate relative to the base 31 along the vertical direction of the base 31 to push the front cover assembly 2 out of the multiple positioning mechanisms 32.

[0047] The pushing portion 331 can move relative to the base 31, such as the pushing portion 331 rotates relative to the base 31 to push the front cover assembly 2 out of the plurality of positioning mechanisms 32. The pushing portion 331 is generally hinged on the base 31. In addition, the pushing portion 331 also requires a pushing driving member 332 to provide a certain power for the pushing portion 331 to drive the pushing portion 331 to move relative to the base 31 along the base 31. Specifically, the pushing mechanism 33 also includes a pushing driving member 332, one end of the pushing driving member 332 is fixed to the pushing portion 331, and the other end of the pushing driving member 332 is fixed to the base 31. The pushing driving member 332 is extended and retracted in a direction close to or away from the front cover assembly 2, so that the pushing portion 331 rotates relative to the base 31.

[0048] The pushing drive member 332 can be a motor, a cylinder, or other types of drives. The use of a motor drive can ensure a certain driving accuracy, can achieve a high speed, and has strong adaptability; the use of a cylinder drive is easy to install and maintain, and does not require high requirements from the user; since the cylinder drive is easy to install and maintain, and does not require high requirements from the user, in one implementable method of the present application, the pushing drive portion 332 uses a cylinder drive.

[0049] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8 Since the assembly device 3 includes a plurality of positioning mechanisms 32, the plurality of positioning mechanisms 32 are used to position different front cover assemblies 2 respectively, and each positioning mechanism 32 can switch between the positioning state and the avoidance state. If the switching is performed manually, the switching time of the positioning mechanism 32 will be affected. Therefore, a switching mechanism 42 is also provided on the assembly device 3. The switching mechanism 42 is used to provide power to drive the corresponding positioning mechanism 32 to switch between the positioning state and the avoidance state. In this way, the corresponding positioning mechanism 32 can be switched according to the front cover assemblies 2 of different models, saving switching time.

[0050] The switching mechanism 42 is used to provide power for each positioning mechanism 32 to switch between the positioning state and the avoidance state. In one possible implementation of the present application, the switching mechanism 42 includes a plurality of driving members 421, and the plurality of driving members 421 are connected to the plurality of positioning mechanisms 32 in a one-to-one correspondence. The driving members 421 are used to provide power for the corresponding positioning mechanism 32 to switch between the positioning state and the avoidance state. It can be understood that the above description does not mean that the technical solution provided in this embodiment can only be driven by a driving member. Under the premise of not affecting the implementation purpose, those skilled in the art can also use manual drive.

[0051] Since the assembly device 3 includes a plurality of positioning mechanisms 32, the plurality of positioning mechanisms 32 are respectively connected to the base 31, each positioning mechanism 32 is used to respectively position a different front cover assembly 2, and each positioning mechanism 32 can switch between a positioning state and an avoidance state, wherein when the positioning mechanism 32 is in the positioning state, it can position the front cover assembly 2 in the position to be positioned, and when the positioning mechanism 32 is in the avoidance state, it can avoid the front cover assembly 2 in the position to be assembled. At this time, the positioning state is to completely position the front cover assembly 2 on the positioning mechanism 32. In order to accurately position the front cover assembly 2, it is necessary not only to position the outer wall of the front cover assembly 2, but also to position the inner wall of the front cover assembly 2. In some embodiments provided in the present application, the positioning mechanism 32 includes a positioning portion 321, the positioning portion 321 includes a bracket 3211, a stop member 3212 and a support member 3213, the stop member 3212 and the support member 3213 are connected to the bracket 3211, and can move relative to the bracket 3211 in a direction close to or away from the front cover assembly 2. When the positioning mechanism 32 is in a positioning state, the stop member 3212 abuts against the outer wall of the front cover assembly 2 in the position to be assembled, and the support member 3213 abuts against the inner wall of the front cover assembly 2 in the position to be assembled, and supports the front cover assembly 2.

[0052] It should be noted that the abutment member 3212 is used to abut against the outer wall of the front cover assembly 2 in the position to be assembled. Correspondingly, the abutment driving member 4211 is also needed to provide the abutment member 3212 with power for abutting against the outer wall of the front cover assembly 2 in the position to be assembled. Specifically, the driving member 421 also includes an abutment driving member 4211. When the abutment driving member 4211 is opened, the abutment driving member 4211 provides the abutment member 3212 with power for abutting against the outer wall of the front cover assembly 2 in the position to be assembled.

[0053] Similarly, the support member 3213 abuts against the inner wall of the front cover assembly 2 in the position to be assembled and supports the front cover assembly 2. Correspondingly, the support driving member 4212 is also required to provide the support member 3213 with power to abut against the inner wall of the front cover assembly 2 in the position to be assembled. Specifically, the driving member 421 also includes a support driving member 4212. When the support driving member 4212 is opened, the support driving member 4212 provides the support member 3213 with power to abut against the inner wall of the front cover assembly 2 in the position to be assembled.

[0054] Specifically, the abutting driving member 4211 and the supporting driving member 4212 can be a motor, a cylinder, or other types of drives. The use of motor drive can ensure a certain driving accuracy, can achieve a high speed, and has strong adaptability; the use of cylinder drive is easy to install and maintain, and does not require high requirements from the user; since the cylinder drive is easy to install and maintain, and does not require high requirements from the user, in one implementable method of the present application, the abutting driving member 4211 and the supporting driving member 4212 use cylinder drive.

[0055] Reference Figure 2 , Figure 3 and Fig. 9When there are two positioning mechanisms 32, and the positioning mechanism 32 includes a positioning portion 321, and the positioning portion 321 includes a supporting member 3212 and a supporting member 3213, an example of how the two positioning mechanisms 32 perform conversion of two front cover assemblies 2 under the switching of the switching mechanism 42 is provided. Similar to the above embodiment, the two front cover assemblies 2 include a front cover assembly of vehicle type A and a front cover assembly of vehicle type B. When the current workstation needs to assemble the front cover assembly of vehicle type A, the first supporting member 42121 in the supporting member 4212 in the positioning portion 321 of the corresponding positioning mechanism 32 is opened, and the first supporting member 32131 in the supporting member 3213 is used to abut against the inner wall of the front cover assembly 2 of vehicle type A in the position to be assembled under the action of the first supporting member 42121, and support the front cover assembly 2. The abutting driving member 4211 is opened, and the first abutting member 32121 in the abutting member 3212 abuts against the outer wall of the front hood assembly 2 of the vehicle model A in the assembly position under the action of the abutting driving member 4211, and the second supporting driving member 42122 in the supporting driving member 4212 is closed; then, if the current station needs to assemble the front hood assembly of the vehicle model B, the second supporting driving member 42122 in the supporting driving member 4212 is opened, and the second supporting member 32132 in the supporting member 3213 is opened. Under the action of the second supporting driving member 42122, it is used to abut against the inner wall of the front hood assembly 2 of the vehicle type B in the position to be assembled, and support the front hood assembly 2, the abutting driving member 4211 is closed, so that the first abutting member 32121 abutting against the outer wall of the front hood assembly 2 of the vehicle type A is avoided, and the second abutting member 32122 in the abutting member 3212 is used to abut against the outer wall of the front hood assembly 2 of the vehicle type A in the position to be assembled, and the first supporting driving member 42121 in the supporting driving member 4212 is closed.

[0056] It should be supplemented that, in addition to the function of abutting against the inner wall of the front cover assembly 2 in the position to be assembled and supporting the front cover assembly 2, the support member 3213 also has the function of detecting whether it can completely fit with the inner wall of the front cover assembly 2, and can also have the function of measuring the position inside the front cover assembly 2. The support member 3213 can be a positioning block, the support member 3213 can also be a combination of a positioning block and an H-shaped block, the support member 3213 can also be a combination of a positioning block, an H-shaped block and a measuring reference, and the present application does not impose any restrictions on this.

[0057] In order to further accurately position the front cover assembly 2, the present application also provides an implementable solution, the positioning portion 321 includes a positioning pin 3214, the positioning pin 3214 is connected to the bracket 3211, and can move relative to the bracket 3211 in a direction close to or away from the front cover assembly 2; when the positioning mechanism 32 is in a positioning state, the abutment member 3212 abuts against the outer wall of the front cover assembly 2 in the position to be assembled, and the support member 3213 abuts against the inner wall of the front cover assembly 2 in the position to be assembled and supports the front cover assembly 2, and the positioning pin 3214 extends into the positioning hole of the inner wall of the front cover assembly 2, which further limits the relative position relationship between the front cover assembly 2 and the positioning mechanism 32.

[0058] It should be noted that, refer to Figure 1 and Fig. 9 The positioning pin 3214 extends into the positioning hole on the inner wall of the front cover assembly 2. Correspondingly, a positioning drive is required to provide power for the positioning pin 3214 to extend into the positioning hole on the inner wall of the front cover assembly 2. Specifically, the drive 421 also includes a positioning drive. When the positioning drive is opened, the positioning drive provides power for the positioning pin 3214 to extend into the positioning hole on the inner wall of the front cover assembly 2.

[0059] Since the support member 3213 abuts against the inner wall of the front cover assembly 2 in the position to be assembled and supports the front cover assembly 2, and the positioning pin 3214 extends into the positioning hole of the inner wall of the front cover assembly 2, both are for positioning the inner wall of the front cover assembly 2. In order to save design costs, no positioning drive member may be provided, and only the support drive member 4212 is provided. When the support drive member 4212 is opened, the support drive member 4212 provides the support member 3213 with power to abut against the inner wall of the front cover assembly 2 in the position to be assembled, and also provides the positioning pin 3214 with power to extend into the positioning hole of the inner wall of the front cover assembly 2. When there are two positioning mechanisms 32, the positioning parts 321 of the two positioning mechanisms 32 both include the abutting member 3212, the support member 3213 and the positioning pin 3214.

[0060] Reference Figure 2 , Figure 3 and Fig. 9When there are two positioning mechanisms 32, and the positioning portion 321 of the positioning mechanism 32 includes a support member 3212, a support member 3213 and a positioning pin 3214, an example of how the two positioning mechanisms 32 complete the conversion of the two front cover assemblies 2 under the switching of the switching mechanism 42 is the same as the above embodiment. The two front cover assemblies 2 include a front cover assembly of a vehicle model A and a front cover assembly of a vehicle model B. If the current workstation needs to assemble the front cover assembly of the vehicle model A, the first support driving member 4212 in the support driving member 4212 1 is opened, the first supporting member 32131 in the supporting member 3213 abuts against the inner wall of the front cover assembly 2 of the vehicle type A in the to-be-assembled position under the action of the first supporting driving member 42121, and supports the front cover assembly 2 of the vehicle type A, the first locating pin 32141 in the locating pin 3214 extends into the locating hole on the inner wall of the front cover assembly 2 of the vehicle type A under the action of the first supporting driving member 42121, the abutting driving member 4211 is opened, and the first abutting member 32121 in the abutting member 3212 abuts against the abutting driving member 42121. 11, it abuts against the outer wall of the front hood assembly 2 of the vehicle type A in the position to be assembled, and the second support driving member 42122 in the support driving member 4212 is closed; then, if the current station needs to assemble the front hood assembly 2 of the vehicle type B, the second support driving member 42122 in the support driving member 4212 is opened, and the second support member 32132 in the support member 3213 abuts against the inner wall of the front hood assembly 2 of the vehicle type B in the position to be assembled under the action of the second support driving member 42122, and Supporting the front hood assembly 2 of vehicle type B, the second positioning pin 32142 in the positioning pin 3214 is used to extend into the positioning hole of the inner wall of the front hood assembly 2 of vehicle type B under the action of the second supporting driving member 42122, and the abutting driving member 4211 is closed, so that the first abutting member 32121 abutting against the outer wall of the front hood assembly 2 of vehicle type A is avoided, and the second abutting member 32122 in the abutting member 3212 abuts against the outer wall of the front hood assembly of vehicle type B, and the first supporting driving member 42121 in the supporting driving member 4212 is closed.

[0061] If the positioning portion 321 only includes the abutment member 3212, the support member 3213 and the positioning pin 3214, it is impossible to determine the relative position relationship between the front cover assembly 2 and the vehicle body frame 1, and accurate installation cannot be performed. For this reason, the present application provides an implementable solution, so that the positioning portion 321, in addition to the abutment member 3212, the support member 3213 and the positioning pin 3214, also includes a detection member 3215, so as to accurately install the front cover assembly 2 on the vehicle body frame 1.

[0062] Reference Fig. 9Specifically, the positioning portion 321 includes a detection member 3215, and the detection member 3215 is used to detect the position of the front cover assembly 2. Since the sensor has the characteristics of miniaturization, digitization, intelligence, multi-function, systematization, and networking, in order to accurately install the front cover assembly 2 on the vehicle body frame 1 and save space, for example, the detection member 3215 can be a sensor, which is a detection device that can sense the measured information and can change the sensed information into an electrical signal or other required form of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording and control.

[0063] Reference Figure 2 , Figure 3 and Fig. 9When there are two positioning mechanisms 32 and the positioning portion 321 of the positioning mechanism 32 includes abutment member 3212, a support member 3213, a positioning pin 3214, and a detection member 3215, an example of how the two positioning mechanisms 32 complete the conversion of two front cover assemblies 2 under the switching of the switching mechanism 42 is provided. Similar to the above embodiment, the two front cover assemblies 2 include a front cover assembly of vehicle type A and a front cover assembly of vehicle type B. When the current workstation needs to assemble the front cover assembly of vehicle type A, the first support driving member 42121 in the support driving member 4212 is opened, and the first support member 32131 in the support member 3213 abuts against the front cover of vehicle type A in the position to be assembled under the action of the first support driving member 42121. The front hood assembly 2 is mounted on the inner wall of the vehicle type A and supports the front hood assembly 2 of the vehicle type A. The first locating pin 32141 in the locating pin 3214 is used to extend into the locating hole on the inner wall of the front hood assembly 2 of the vehicle type A under the action of the first supporting driving member 42121, and the abutting driving member 4211 is opened. The first abutting member 32121 in the abutting member 3212 abuts against the outer wall of the front hood assembly 2 of the vehicle type A in the position to be assembled under the action of the abutting driving member 4211, and the second supporting driving member 42122 in the supporting driving member 4212 is closed. The first detecting member 32151 in the detecting member 3215 senses that the front hood assembly of the vehicle type A has reached the installation position of the body frame 1 of the vehicle type A, and the hinge nut of the front hood assembly of the vehicle type A is manually tightened. Next, if the current workstation needs to assemble the front hood assembly of model B, the second support driving member 42122 in the support driving member 4212 is opened, and the second support member 32132 in the support member 3213 abuts against the inner wall of the front hood assembly 2 of model B in the to-be-assembled position under the action of the second support driving member 42122, and supports the front hood assembly 2 of model A, and the second locating pin 32142 in the locating pin 3214 is used to extend into the inner wall of the front hood assembly 2 of model B under the action of the second support driving member 42122. In the positioning hole, the abutment driving member 4211 is closed, so that the first abutment member 32121 abutting against the outer wall of the front hood assembly of vehicle type A is avoided, and the second abutment member 32122 in the abutment member 3212 abuts against the outer wall of the front hood assembly 2 of vehicle type B in the position to be assembled, and the first support driving member 42121 in the support driving member 4212 is closed, and the second detection member 32152 in the detection member 3215 senses that the front hood assembly of vehicle type B has reached the installation position of the body frame 1 of vehicle type B, and the hinge nut of the front hood assembly of vehicle type B is tightened manually.

[0064] This application also provides some other embodiments, refer to Figure 1 , Fig. 9 and Fig.10A translation positioning mechanism 34 is provided between the base 31 and the plurality of positioning mechanisms 32. The translation positioning mechanism 34 is used to drive the plurality of positioning mechanisms 32 to approach or move away from the front cover assembly 2, so that the plurality of positioning mechanisms 32 can be translated to a position where they can switch between a positioning state and an avoidance state. In this way, the relative positions of the plurality of positioning mechanisms 32 relative to the vehicle body frame 1 or the front cover assembly 2 can be conveniently adjusted.

[0065] Specifically, when the assembly device 3 receives the start signal, the multiple positioning mechanisms 32 are driven by the translation positioning mechanism 34 to approach the front cover assembly 2 until the multiple positioning mechanisms 32 can be translated to a position where they can switch between the positioning state and the avoidance state. When one of the multiple positioning mechanisms 32 positions the corresponding front cover assembly 2, the front cover assembly 2 is installed on the vehicle body frame 1 by manually tightening the hinge nut of the front cover assembly 2. The pushing portion 331 of the pushing mechanism 33 can move relative to the base 31 to push the front cover assembly 2 out of the multiple positioning mechanisms 32. After that, the multiple positioning mechanisms 32 can also be driven by the translation positioning mechanism 34 to move away from the front cover assembly 2 and return to their original positions.

[0066] The translation positioning mechanism 34 may include a gear rack, a sliding guide rail, or other types of translation positioning members 341, and the present application does not limit this. Due to the high manufacturing and installation precision requirements of the gear rack, and the disadvantages of being unsuitable for long-distance transmission and high design cost, preferably, the translation positioning member 341 is a sliding guide rail. Specifically, the translation positioning member 341 extends in the direction in which the multiple positioning mechanisms 32 approach or move away from the front cover assembly 2, and the translation positioning member 341 is slidably connected to the multiple positioning mechanisms 32, so that the multiple positioning mechanisms 32 can all be translated to a position where the positioning state and the avoidance state can be switched.

[0067] In addition, in order to prevent impurities from entering the sliding guide rail and affecting the stability of the positioning mechanism 32 sliding horizontally along the base 31, a sliding cover plate can be provided on the sliding guide rail to cover part of the sliding guide rail and prevent impurities from entering the interior of the sliding guide rail.

[0068] It should be noted that, if a sliding guide rail is used for the translational positioning member 341, the sliding guide rail is used to drive the multiple positioning mechanisms 32 to move closer to or away from the front cover assembly 2. Correspondingly, the translational positioning mechanism 34 should also include a translational positioning drive member 342, which is connected to the sliding guide rail. The translational positioning drive member 342 is used to provide power for the multiple positioning mechanisms 3 to move closer to or away from the front cover assembly 2.

[0069] Specifically, the translational positioning drive component 342 can be a motor, a cylinder, or other types of drives. The use of a motor drive can ensure a certain driving accuracy, can achieve a high rotation speed, and has strong adaptability; the use of a cylinder drive is easy to install and maintain, and does not require high requirements from the user; since the cylinder drive is easy to install and maintain, and does not require high requirements from the user, in one implementable method of the present application, the translational positioning drive component 342 uses a cylinder.

[0070] Reference Fig.10 , since the translation positioning mechanism 34 is used to drive the multiple positioning mechanisms 32 to approach or move away from the front cover assembly 2, but when the positioning mechanism 32 reaches a position where it can switch between the positioning state and the avoidance state, the positioning mechanism 32 can also move along the horizontal direction of the base 31 during the process of the positioning mechanism 32 positioning the front cover assembly 32, resulting in the positioning mechanism 32 being unable to position the front cover assembly 2 or inaccurately positioning. In addition, when the site is uneven and has a certain inclination angle along the horizontal direction of the base 31, the multiple positioning mechanisms 32 may spontaneously displace along the horizontal direction of the base 31, requiring the operator to manually fix them, wasting time. To this end, an embodiment of the present application provides an implementable method, in which a locking positioning mechanism 35 is provided between the multiple positioning mechanisms 32 and the translation positioning mechanism 34, so that the multiple positioning mechanisms 32 can be locked to a position where they can switch between the positioning state and the avoidance state. Specifically, the locking positioning mechanism 35 includes a locking positioning member 351, which is arranged on the translation positioning mechanism. When the multiple positioning mechanisms 32 approach the front cover assembly 32 and reach a position where the positioning state and the switching state can be switched, the multiple positioning mechanisms 32 can be abutted against the locking positioning member 351 to lock the multiple positioning mechanisms 32 to a position where the positioning state and the avoidance state can be switched.

[0071] The locking positioning member 351 may be a clamping protrusion provided on the translation positioning mechanism 34, and the clamping protrusion is provided at a position where the plurality of positioning mechanisms 32 can switch between the positioning state and the avoidance state. When the translation positioning mechanism 34 drives the plurality of positioning mechanisms 32 to translate to a position where the positioning state and the avoidance state can be switched, the plurality of positioning mechanisms 32 can abut against the clamping protrusion, so that the plurality of positioning mechanisms can be locked to a position where the positioning state and the avoidance state can be switched.

[0072] Reference Fig. 9 and Fig.10The locking positioning member 351 can also be provided at the first locking cylinder 3511 and the second locking cylinder 3512 at both ends of the translation positioning mechanism 34. When the positioning mechanism 32 moves away from the front cover assembly 2 along the horizontal direction of the base 31, the first locking cylinder 351 close to the front cover assembly 2 opens, and the plurality of positioning mechanisms 32 move along the horizontal direction of the base 31 and away from the front cover assembly 2 under the drive of the translation positioning mechanism 34 until the plurality of positioning mechanisms 32 are completely separated from the front cover assembly 2 and the second locking cylinder 351 away from the front cover assembly 2 is opened. 2 is closed to lock the positioning mechanism 32 and move it along the horizontal direction of the base 31 and away from the front cover assembly 2; when the positioning mechanism 32 approaches the front cover assembly 2 along the horizontal direction of the base 31, the second locking cylinder 3512 away from the front cover assembly 2 is opened, and the multiple positioning mechanisms 32 are driven by the translation positioning mechanism 34 to move along the horizontal direction of the base 31 and close to the front cover assembly 2 until they reach a position where the multiple positioning mechanisms 32 can switch between the positioning state and the avoidance state, and the first locking cylinder 351 close to the front cover assembly 2 is closed.

[0073] When the plurality of positioning mechanisms 32 reach a position where they can switch between the positioning state and the avoidance state in the horizontal direction of the base 31, the locking positioning mechanism 35 works to lock the movement of the positioning mechanism 32 in the horizontal direction of the base 31. The operator needs to manually observe whether the plurality of positioning mechanisms 32 produce the target displacement in the horizontal direction of the base 31. The observation result is inaccurate. In order to make the observed structure more accurate, a first contact in place switch 38, a second contact in place switch 40, a first induction switch 39 and a second induction switch 41 are provided at both ends of the translation positioning mechanism 34. The first contact in place switch 38 is electrically connected to the first induction switch 39 and is simultaneously provided at one end close to the front cover assembly 2 to judge and display whether the positioning mechanism 32 is in the horizontal direction of the base 31 and close to the front cover assembly 2. When the positioning mechanism 32 is close to the front cover assembly 2 and reaches a position where the positioning state and the avoidance state can be switched, the second contact position switch 40 is electrically connected to the second inductive switch 41 and is simultaneously arranged at the end away from the front cover assembly 2 to judge and display the position of the positioning mechanism 32 along the horizontal direction of the base 31 and away from the front cover assembly 2 until the multiple positioning mechanisms 32 are completely separated from the front cover assembly 2. Taking the first contact position switch 38 and the first inductive switch 39 as an example, when the positioning mechanism 32 reaches a position close to the front cover assembly 2 and reaches a position where the positioning state and the avoidance state can be switched, the contact position switch is triggered, causing the first inductive switch 39 to generate an electrical signal. Under the instruction of the electrical signal, the operator makes the locking positioning mechanism 35 work to limit the movement of the positioning mechanism 32 along the horizontal direction of the base 31. Since the sensor has the characteristics of miniaturization, digitization, intelligence, multi-function, systematization, and networking, the first inductive switch 39 and the second inductive switch 41 here can also be sensors.

[0074] The present application also provides some other embodiments, refer to Figure 1 and Fig.10 A translation pushing mechanism 36 is provided between the base 31 and the pushing mechanism 33, and the translation pushing mechanism 36 is used to drive the pushing mechanism 33 to move in the horizontal direction of the base 31. The pushing mechanism 33 moves in the horizontal direction of the base 31, and the relative position of the pushing mechanism 33 with respect to the vehicle body frame 1 or the front cover assembly 2 can be conveniently adjusted, so that the pushing mechanism 33 reaches the target position.

[0075] Specifically, when the assembly device 3 receives the start signal, the pushing mechanism 33 approaches the front cover assembly 2 under the drive of the translation pushing mechanism 36 until the pushing mechanism 33 reaches a position where it can push the front cover assembly 2 to disengage from the positioning mechanism 32. The pushing portion 331 of the pushing mechanism 33 can move relative to the base 31 to push the front cover assembly 2 to disengage from the multiple positioning mechanisms 32. After the multiple positioning mechanisms 32 are completely disengaged from the front cover assembly 2, the pushing mechanism 33 can be driven by the translation pushing mechanism 36 to move away from the front cover assembly 2 and return to its original position.

[0076] The translation push mechanism 36 may include a gear rack, a sliding guide rail, or other types of translation push members 361, and the present application does not limit this. Due to the high manufacturing and installation precision requirements of the gear rack, and the disadvantages of being unsuitable for long-distance transmission and high design cost, and in order to be consistent with the first translation positioning member 341, the translation push member 361 is also selected as a sliding guide rail.

[0077] In addition, in order to prevent impurities from entering the sliding guide rail and affecting the stability of the pushing mechanism 33 sliding horizontally along the base 31, a sliding cover can be provided on the sliding guide rail to cover part of the sliding guide rail and prevent impurities from entering the interior of the sliding guide rail.

[0078] It should be noted that, if a sliding guide rail is used for the translation push member 361, the sliding guide rail is used to drive the pushing mechanism 33 to be displaced in the horizontal direction of the base 31. Correspondingly, the translation push mechanism 36 should also include a translation push drive member 362, which is connected to the sliding guide rail. The translation push drive member 362 is used to provide the sliding guide rail with power to drive the pushing mechanism 33 to be displaced in the horizontal direction of the base 31.

[0079] Specifically, the translational push drive member 362 can be a motor, a cylinder, or other types of drives. The use of a motor drive can ensure a certain driving accuracy, can achieve a high speed, and has strong adaptability; the use of a cylinder drive is easy to install and maintain, and does not require high requirements from the user; since the cylinder drive is easy to install and maintain, and does not require high requirements from the user, in one implementable method of the present application, the translational push drive member 362 uses a cylinder.

[0080] Reference Figure 1 , Fig. 9 and Fig.10 The push mechanism 33 is preferably actuated by a user to move the push mechanism 33 in a horizontal direction relative to the base 31 so as to prevent the push mechanism 33 from moving out of the positioning mechanism 32. Specifically, the locking push mechanism 37 includes a locking push member 371, and the locking positioning member 371 is arranged on the translation push mechanism 36. When the pushing mechanism 33 approaches the front cover assembly 32 and reaches a position where the front cover assembly 2 can be separated from multiple positioning mechanisms 32, the pushing mechanism 33 can abut against the locking push member 371 to lock the movable part 331 to a position where the front cover assembly 2 can be separated from multiple positioning mechanisms 32.

[0081] The locking pusher 371 may be a snap-on protrusion disposed on the translation positioning mechanism 36, and the snap-on protrusion is disposed at a position where the pushing mechanism can cause the front cover assembly 2 to be separated from the plurality of positioning mechanisms 32. When the translation pushing mechanism 36 drives the pushing mechanism 33 to reach a position where the front cover assembly 2 can be separated from the plurality of positioning mechanisms 32, the pushing mechanism 33 may abut against the snap-on protrusion to lock the pushing mechanism 33 to a position where the front cover assembly 2 can be separated from the plurality of positioning mechanisms 32.

[0082] Reference Figure 1 and Fig.10The locking pusher 371 can also be provided with a third locking cylinder 3711 and a fourth locking cylinder 3712 at both ends of the translation push mechanism 36. When the push mechanism 33 moves away from the front cover assembly 2 along the horizontal direction of the base 31, the third locking cylinder 3711 close to the front cover assembly 2 opens, and the push mechanism 33 moves along the horizontal direction of the base 31 and away from the front cover assembly 2 under the drive of the translation push mechanism 36 until it reaches a position where the push mechanism 32 does not interfere with the front cover assembly 2, and the fourth locking cylinder 3711 away from the front cover assembly 2 is locked. 2 is closed to lock the pushing mechanism 33 and move it along the horizontal direction of the base 31 and away from the front cover assembly 2; when the pushing mechanism 33 approaches the front cover assembly 2 along the horizontal direction of the base 31, the fourth locking cylinder 3712 away from the front cover assembly 2 is opened, and the pushing mechanism 33 moves along the horizontal direction of the base 31 and close to the front cover assembly 2 under the drive of the translation pushing mechanism 36, until it reaches the position where the pushing mechanism 32 can push the front cover assembly 2 to disengage from the multiple positioning mechanisms 32, and the third locking cylinder 3711 close to the front cover assembly 2 is closed.

[0083] When the pushing mechanism 33 moves in the horizontal direction of the base 31, the pushing mechanism 32 reaches a position where it can push the front cover assembly 2 to disengage from the multiple positioning mechanisms 32 or a position where the pushing mechanism 32 does not interfere with the front cover assembly 2, and the locking pushing mechanism 37 works to lock the movement of the pushing mechanism 33 in the horizontal direction of the base 31. The operator needs to manually observe whether the pushing mechanism 33 produces a target displacement in the horizontal direction of the base 31, which leads to inaccurate observation of the structure. In order to make the observed structure more accurate, a third contact in place switch, a fourth contact in place switch, a third induction switch and a fourth induction switch can be set at both ends of the translation pushing mechanism 36. The third contact in place switch is electrically connected to the third induction switch and is simultaneously set at one end close to the front cover assembly 2 to judge and display that the pushing mechanism 33 is in the horizontal direction of the base 31 and close to the front cover assembly 2 until the pushing mechanism 32 reaches a position where the front cover assembly 2 can be pushed out of the multiple positioning mechanisms 32. The fourth contact in place switch is electrically connected to the fourth induction switch and is simultaneously set at one end away from the front cover assembly 2 to judge and display that the pushing mechanism 33 is in the horizontal direction of the base 31 and the pushing mechanism 32 does not interfere with the position of the front cover assembly 2. Taking the third contact in place switch and the third induction switch as an example, when the pushing mechanism 33 reaches close to the front cover assembly 2 until the pushing mechanism 32 reaches a position where the front cover assembly 2 can be pushed out of the multiple positioning mechanisms 32, the third contact in place switch is triggered, causing the third induction switch to generate an electrical signal. Under the instruction of the electrical signal, the operator makes the locking pushing mechanism 37 work to limit the movement of the pushing mechanism 33 in the horizontal direction of the base 31. Since sensors have the characteristics of miniaturization, digitization, intelligence, multi-function, systematization and networking, the third induction switch and the fourth induction switch here can also be sensors.

[0084] Of course, the translational positioning member 341 in the translational positioning mechanism 34 and the translational pushing member 361 in the translational pushing mechanism 36 can both be located on the same platform 311, that is, the translational positioning mechanism 34 and the translational pushing mechanism 36 share one platform 311. In order to save costs, in an implementable method of the present application, the first contact in place switch 38, the second contact in place switch 40, the first sensing switch 39 and the second sensing switch 41 are all located on the platform 311 shared by the translational positioning mechanism 34 and the translational pushing mechanism 36, which can determine and display whether the multiple positioning mechanisms 32 are displaced in the horizontal direction of the base 31, and can also determine and display whether the pushing mechanism 33 is displaced in the horizontal direction of the base 31.

[0085] Reference Figure 1 Since the above-mentioned drives are all cylinder driven, there are multiple air pipes and cables. In order to avoid damage to the air pipes and cables during movement, a drag chain 312 is also provided on the base 31. Multiple air pipes and cables can be provided in the drag chain 312 to protect the air pipes and cables.

[0086] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
