Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring assembly, in particular to sealing ring assembly equipment. Background Art

[0002] The production and manufacturing of automotive parts involves many sealing ring assembly scenarios. Current sealing ring assembly equipment can usually only produce at a single station and has a slow pace.

[0003] Specifically, the current assembly process of the sealing ring assembly equipment is: take the sealing ring at the material taking position → stretch the sealing ring → move it to the workpiece → install the sealing ring on the workpiece → return to the material taking position to take the sealing ring... and repeat this cycle until the sealing ring assembly of all workpieces is completed.

[0004] The single-station working mode of the current sealing ring assembly equipment means that only one operation can be performed at a time, resulting in a long time-consuming sealing ring assembly and low production efficiency.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the utility model, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In view of this, the utility model provides a sealing ring assembly device, which can work in a multi-station form, so that the sealing ring can be taken and installed at the same time, which greatly shortens the sealing ring assembly time and improves production efficiency.

[0007] One aspect of the utility model provides a sealing ring assembly device, including: a first rotating machine and a plurality of sealing ring stretching units arranged on the first rotating machine, each of the sealing ring stretching units including a stretching needle component and a first driving mechanism capable of driving the stretching needle component to move, the first rotating machine can be rotated until at least one sealing ring stretching unit is located at a material picking work position and at least one sealing ring stretching unit is located at a transfer work position; a second rotating machine and a plurality of sealing ring installation units arranged on the second rotating machine, each of the sealing ring installation units including a sleeve component and a second driving mechanism capable of driving the sleeve component to move, the second rotating machine can be rotated until at least one sealing ring installation unit is located at the transfer work position and at least one sealing ring installation unit is located at the installation work position.

[0008] The first driving mechanism can drive the support needle component to move and open, so as to pick up and stretch the sealing ring; the second driving mechanism can drive the sleeve component to move, so as to remove the sealing ring on the support needle component and install it on the target workpiece. By setting multiple sealing ring stretching units on the first rotating machine, and the first rotating machine can rotate to at least one sealing ring stretching unit located at the material picking work position and at least one sealing ring stretching unit located at the transfer work position, and setting multiple sealing ring installation units on the second rotating machine, and the second rotating machine can rotate to at least one sealing ring installation unit located at the transfer work position and at least one sealing ring installation unit located at the installation work position; then, the sealing ring stretching unit located at the material picking work position can pick up and stretch the sealing ring, the sealing ring installation unit located at the transfer work position can remove the sealing ring from the corresponding sealing ring stretching unit, and the sealing ring installation unit located at the installation work position can install the sealing ring on the target workpiece. In this way, the material picking and installation of the sealing ring are carried out simultaneously, which can greatly shorten the sealing ring assembly time and improve production efficiency.

[0009] In some embodiments, the pin member includes two parallel cylindrical pins.

[0010] Two cylindrical support pins are used to open the sealing ring, and the expansion range is small, which can greatly reduce the probability of damage to the sealing ring.

[0011] In some embodiments, the first driving mechanism connects the two cylindrical pins via a pair of parallel opening and closing jaws.

[0012] The first driving mechanism can drive the parallel opening and closing jaws to open in parallel, drive the cylindrical support needle to open, so as to open the sealing ring; in addition, the first driving mechanism can also drive the parallel opening and closing jaws to move forward and backward, drive the cylindrical support needle to move, so as to realize the material collection and transportation of the sealing ring.

[0013] In some embodiments, the transfer workstation is provided with a tooling plate. When the sealing ring installation unit is located at the transfer workstation, the first driving mechanism can drive the support needle component to move until the sealing ring part sleeved on the support needle component contacts the tooling plate and tilts.

[0014] The first driving mechanism drives the pin support component to move so that the sealing ring part contacts the tooling plate and tilts, thereby leaving space for the sealing ring installation unit to remove the sealing ring.

[0015] In some embodiments, the sleeve component comprises a sleeve provided with an annular groove.

[0016] In this way, when the sleeve is driven by the second driving mechanism to extend into the sealing ring, the annular groove can hook the sealing ring to ensure that the sealing ring is not taken away when the support needle component is withdrawn, so that the sealing ring can be removed from the support needle component.

[0017] In some embodiments, the sleeve component also includes a push cylinder that is telescopically sleeved outside the sleeve; when the sealing ring installation unit is located at the installation working position, the second driving mechanism can drive the sleeve to abut the target workpiece, and drive the push cylinder to push the sealing ring sleeved in the annular groove to the target position of the target workpiece.

[0018] During the installation of the sealing ring, the second driving mechanism first drives the sleeve and the push cylinder to move together until the sleeve abuts the target workpiece, and then drives the push cylinder to push the sealing ring sleeved in the annular groove until the sealing ring is pushed to the target position. The sleeve and the push cylinder cooperate to avoid the sealing ring from turning over, ensuring that the sealing ring is accurately installed at the target position of the target workpiece to ensure sealing performance.

[0019] In some embodiments, the push cylinder is connected to the sleeve via a spring.

[0020] In this way, during the installation of the sealing ring, the sleeve and the push cylinder can move together first, and then the push cylinder compresses the spring and moves relative to the sleeve to install the sealing ring in place.

[0021] In some embodiments, the first rotating platform is driven to rotate by a third driving mechanism, and the second rotating platform is driven to rotate by a fourth driving mechanism.

[0022] In this way, the rotation of the first rotating platform and the second rotating platform is achieved.

[0023] In some embodiments, each driving mechanism is a cylinder.

[0024] Through the cylinder, each component can be driven to move stably and accurately.

[0025] Compared with the prior art, the beneficial effects of the present invention include at least:

[0026] The sealing ring assembly equipment of the present invention can work in a multi-station form through the cooperation of multiple sealing ring spreading units and a first rotating machine as well as multiple sealing ring installation units and a second rotating machine, so that the sealing ring can be taken and installed at the same time, which greatly shortens the sealing ring assembly time, improves production efficiency, and ensures accurate installation of the sealing ring.

Figure 2 It shows the structure of the sealing ring expansion unit located at the material taking working position. Figure 3 and Figure 4 The structure of the sealing ring expansion unit and the sealing ring installation unit located at the transfer work station is shown in the figure. Figure 5 The structure of the sealing ring installation unit at the installation work position is shown in FIG. Figures 1 to 5 As shown, the sealing ring assembly device provided by the embodiment of the utility model includes:

[0037] A first rotating machine 10 and a plurality of sealing ring opening units 11 arranged on the first rotating machine 10, each sealing ring opening unit 11 comprises a pin-opening component 111 and a first driving mechanism 112 capable of driving the pin-opening component 111 to move, and the first rotating machine 10 can rotate until at least one sealing ring opening unit 11 is located at a material taking work position A and at least one sealing ring opening unit 11 is located at a transfer work position B;

[0038] The second rotating machine 20 and a plurality of sealing ring installation units 22 arranged on the second rotating machine 20, each sealing ring installation unit 22 includes a sleeve component 222 and a second driving mechanism 223 capable of driving the sleeve component 222 to move, and the second rotating machine 20 can be rotated until at least one sealing ring installation unit 22 is located at the transfer work position B and at least one sealing ring installation unit 22 is located at the installation work position C.

[0039] The first driving mechanism 112 can drive the support needle component 111 to move and open, so as to remove and open the sealing ring 30 ; the second driving mechanism 223 can drive the sleeve component 222 to move, so as to remove the sealing ring 30 on the support needle component 111 and install it on the target workpiece 40 . By arranging a plurality of sealing ring stretching units 11 on the first rotating machine 10, and the first rotating machine 10 can rotate to at least one sealing ring stretching unit 11 at the material picking work position A, and at least one sealing ring stretching unit 11 at the transfer work position B, and arranging a plurality of sealing ring installation units 22 on the second rotating machine 20, and the second rotating machine 20 can rotate to at least one sealing ring installation unit 22 at the transfer work position B, and at least one sealing ring installation unit 22 at the installation work position C; then, the sealing ring stretching unit 11 at the material picking work position A can pick up and stretch the sealing ring 30, the sealing ring installation unit 22 at the transfer work position B can remove the sealing ring 30 from the corresponding sealing ring stretching unit 11, and the sealing ring installation unit 22 at the installation work position C can install the sealing ring 30 on the target workpiece 40. In this way, the material picking and installation of the sealing ring 30 are carried out simultaneously, which can greatly shorten the sealing ring assembly time and improve production efficiency.

[0040] The number of the sealing ring expansion unit 11 and the sealing ring installation unit 22 can be set as required. Figure 1 In the embodiment shown, the sealing ring expansion unit 11 and the sealing ring installation unit 22 each include two, and correspondingly, the material taking workstation A, the transfer workstation B, and the installation workstation C each include one; then in this embodiment, the single sealing ring assembly time can be shortened by at least half. In other embodiments, the number of the sealing ring expansion unit 11 and the sealing ring installation unit 22 can include more than three, and correspondingly, the material taking workstation A, the transfer workstation B, and the installation workstation C are each provided with more than two, which can further shorten the single sealing ring assembly time. How to set it specifically can be comprehensively considered according to the production efficiency requirements and the complexity requirements of the sealing ring assembly equipment.

[0041] In some embodiments, the pin member 111 includes two parallel cylindrical pins.

[0042] The current sealing ring assembly equipment usually uses three claws to open the sealing ring, which is very easy to produce obvious indentations and damage on the sealing ring. When the three claws are disengaged, it is also very easy to produce scars on the sealing ring. However, the utility model uses two cylindrical support pins to open the sealing ring 30, and the expansion range is small, which can greatly reduce the probability of damage to the sealing ring 30.

[0043] In some embodiments, the first driving mechanism 112 connects two cylindrical pins via a pair of parallel opening and closing jaws 114 .

[0044] The first driving mechanism 112 can drive the parallel opening and closing jaws 114 to open in parallel (along the "X" direction), driving the cylindrical support needle to open to open the sealing ring 30; in addition, the first driving mechanism 112 can also drive the parallel opening and closing jaws 114 to move forward and backward (along the "Z" direction), driving the cylindrical support needle to move, so as to realize the material collection and transportation of the sealing ring 30.

[0045] In some embodiments, the transfer work station B is provided with a tooling plate b. When the sealing ring installation unit 22 is located at the transfer work station B, the first driving mechanism 112 can drive the support needle component 111 to move until the sealing ring 30 mounted on the support needle component 111 partially contacts the tooling plate b and tilts.

[0046] The first driving mechanism 112 drives the pin support member 111 to move so that the sealing ring 30 partially contacts the tooling plate b and tilts, thereby leaving space for the sealing ring installation unit 22 to remove the sealing ring 30. Figures 1 to 4As shown, after the first rotating machine 10 drives the sealing ring opening unit 11 to rotate from the material picking workstation A to the transfer workstation B, the first driving mechanism 112 drives the support needle component 111 to retreat along the "Z" direction (specifically, retreat relative to the sealing ring installation unit 22 located at the transfer workstation B) until the bottom of the sealing ring 30 hits the tooling plate b and is blocked by the tooling plate b, but the top of the sealing ring 30 continues to retreat driven by the first driving mechanism 112, so that the sealing ring 30 is tilted as a whole, so that the sleeve component 222 can extend into the sealing ring 30 driven by the second driving mechanism 223 to remove the sealing ring 30 from the support needle component 111.

[0047] In some embodiments, the sleeve component 222 includes a sleeve 222a having an annular groove 222a'.

[0048] In this way, when the sleeve 222a is driven by the second driving mechanism 223 to extend into the sealing ring 30, the annular groove 222a' can hook the sealing ring 30, ensuring that the sealing ring 30 will not be taken away from the pin component 111 when it is withdrawn, so that the sealing ring 30 can be removed from the pin component 111. Specifically, when the sleeve 222a extends into the sealing ring 30, a part of the sealing ring 30 is hooked by the annular groove 222a'; then the first driving mechanism 112 drives the pin component 111 to retreat along the "Z" direction until the sealing ring 30 is separated from the pin component 111. During this process, the annular groove 222a' hooks the sealing ring 30 to prevent the sealing ring 30 from being taken away by the pin component 111, and the sealing ring 30 can be completely inserted into the annular groove 222a' due to its own rebound effect during the process of separating from the pin component 111.

[0049] In some embodiments, the sleeve component 222 also includes a push cylinder 222b that is telescopically sleeved on the outside of the sleeve 222a; when the sealing ring installation unit 22 is located at the installation working position C, the second driving mechanism 223 can drive the sleeve 222a to abut the target workpiece 40, and drive the push cylinder 222b to push the sealing ring 30 sleeved in the annular groove 222a' to the target position of the target workpiece 40.

[0050] During the installation of the sealing ring 30, the second driving mechanism 223 first drives the sleeve 222a and the push cylinder 222b to move together until the sleeve 222a abuts against the target workpiece 40, and then drives the push cylinder 222b to push the sealing ring 30 sleeved in the annular groove 222a' until the sealing ring 30 is pushed to the target position. The sleeve 222a cooperates with the push cylinder 222b to prevent the sealing ring 30 from turning over, ensuring that the sealing ring 30 is accurately installed at the target position of the target workpiece 40 to ensure sealing performance.

[0051] In some embodiments, the push tube 222b is connected to the sleeve 222a via a spring 222c. Thus, during the installation of the sealing ring 30, the sleeve 222a and the push tube 222b can move together first, and then the push tube 222b compresses the spring 222c and moves relative to the sleeve 222a to install the sealing ring 30 in place.

[0052] In some embodiments, the first rotating platform 10 is driven to rotate by a third driving mechanism, and the second rotating platform 20 is driven to rotate by a fourth driving mechanism. In this way, the first rotating platform 10 and the second rotating platform 20 are rotated.

[0053] In some embodiments, each driving mechanism is a cylinder, through which each component can be driven to move stably and accurately.

[0054] Combine the following Figures 1 to 5 As shown, the specific process of sealing ring assembly using sealing ring assembly equipment is explained.

[0055] The sealing ring expansion unit 11 located at the material taking work position A works, and the first driving mechanism 112 drives the support needle component 111 to extend into the sealing ring 30 and expand it, so as to realize the material taking of the sealing ring 30. In this process, the sealing ring installation unit 22 and the sealing ring expansion unit 11 located at the transfer work position B, and the sealing ring installation unit 22 located at the installation work position C can respectively perform the transfer work and the installation work of the sealing ring 30.

[0056] The first rotating machine 10 rotates to drive the sealing ring expansion unit 11 that has completed the material collection to move to the transfer work position B for the transfer of the sealing ring 30, and drives the sealing ring expansion unit 11 originally located at the transfer work position B to move to the material collection work position A for the collection of the sealing ring 30. In this process, the second rotating machine 20 can rotate to drive the sealing ring installation unit 22 originally located at the installation work position C to move to the transfer work position B for the transfer of the sealing ring 30, and drive the sealing ring installation unit 22 originally located at the transfer work position B to move to the installation work position C for the installation of the sealing ring 30.

[0057] The sealing ring expansion unit 11 and the sealing ring installation unit 22 located at the transfer workstation B cooperate to perform the transfer work of the sealing ring 30, specifically: the first driving mechanism 112 drives the support needle component 111 to retreat to tilt the sealing ring 30, the second driving mechanism 223 drives the sleeve component 222 to move toward the sealing ring 30 so that the sealing ring 30 is partially inserted into the annular groove 222a' of the sleeve 222a, and the first driving mechanism 112 continues to drive the support needle component 111 to retreat to separate the sealing ring 30 from the support needle, and the sealing ring 30 is completely inserted into the annular groove 222a' of the sleeve 222a due to the elastic potential energy. In this process, the sealing ring expansion unit 11 located at the material taking workstation A can take the sealing ring 30, and the sealing ring installation unit 22 located at the installation workstation C can install the sealing ring 30.

[0058] The second rotating machine 20 rotates to drive the sealing ring installation unit 22 that has taken the sealing ring 30 to move to the installation work position C for installing the sealing ring 30, and drives the sealing ring installation unit 22 originally located at the installation work position C to move to the transfer work position B for transferring the sealing ring 30. In this process, the first rotating machine 10 can rotate to drive the sealing ring expansion unit 11 originally located at the transfer work position B to move to the material taking work position A for taking the sealing ring 30, and drives the sealing ring expansion unit 11 originally located at the material taking work position A to move to the transfer work position B for transferring the sealing ring 30.

[0059] The sealing ring installation unit 22 located at the installation work position C works, and first drives the sleeve 222a and the push cylinder 222b to move together until the sleeve 222a abuts the target workpiece 40 through the second driving mechanism 223, and then drives the push cylinder 222b to make the push cylinder 222b push the sealing ring 30 sleeved in the annular groove 222a' until the sealing ring 30 is pushed to the target position, so as to complete the installation of the sealing ring 30. In this process, the sealing ring expansion unit 11 located at the material removal work position A can perform the material removal work of the sealing ring 30, and the sealing ring installation unit 22 and the sealing ring expansion unit 11 located at the transfer work position B can perform the transfer work of the sealing ring 30.

[0060] In this way, by taking and installing the sealing ring 30 at the same time, the assembly time of the sealing ring 30 can be greatly shortened, and the assembly time of a single sealing ring can be shortened to less than 3 seconds, effectively improving production efficiency. In addition, each driving mechanism cooperates with each other and is precisely controlled to achieve accurate assembly of the sealing ring 30.

[0061] In summary, the sealing ring assembly equipment of the utility model can work in a multi-station form through the cooperation of multiple sealing ring stretching units 11 and the first rotating machine 10 and multiple sealing ring installation units 22 and the second rotating machine 20, so that the material collection and installation of the sealing ring 30 can be carried out simultaneously, which greatly shortens the sealing ring assembly time, improves production efficiency, and ensures the accurate installation of the sealing ring 30.

[0062] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
