Description

Technical Field

[0001] This application relates to the field of mechanical assembly technology, specifically to a positioning device. Background Technology

[0002] When assembling the center beam of a truck, a positioning device is often required. The center beam includes a partition plate, a lower cover plate, and two web plates arranged opposite each other. During assembly, the web plates are usually placed on the positioning surfaces on both sides of the positioning device, and a clamping device is used to clamp and position the web plates on the positioning surfaces. Then, the web plates, partition plates, and lower cover plates are welded together.

[0003] The proposed solution provides a positioning device that is movable on one side. This device employs a positioning method where one side is movable and the other is fixed. The positioning device includes a fixed side and a movable side, both of which are provided with positioning surfaces. The movable side is rotatably connected to the fixed side via a pin. During assembly, the movable and fixed sides cooperate to position the two web plates 7. After assembly, when the middle beam needs to be lifted and detached from the positioning device, the friction between the web plate 7 of the middle beam and the positioning surface of the movable side during the upward movement causes the movable side to rotate upward around the pin, thus facilitating the lifting of the middle beam.

[0004] However, the pin connection requires a certain clearance, that is, the pin and the fixed side and the positioning side need to be fitted with clearance. As a result, the distance between the positioning side and the fixed side is not fixed, which leads to insufficient positioning accuracy of the web plate 7 and is not conducive to assembly.

[0064] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0065] In the embodiments of the present application, the terms "first" and "second" are mainly used to distinguish the same or similar features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features.

[0066] The first direction in the present embodiment is the left-right direction, the second direction is the front-back direction, and the first direction is perpendicular to the second direction.

[0067] Please refer to Figures 1 to 10 , Figure 1 is a structural schematic view of the positioning device in an embodiment of the present application; Figure 2 is Figure 1 a front view of the positioning device in the embodiment; Figure 3 is Figure 1 a side view of the positioning device in the embodiment; Figure 4 is Figure 1 a top view of the positioning device in the embodiment; Figure 5 is Figure 1 a front view of the positioning base 1 in the embodiment; Figure 6 is Figure 1 a side view of the positioning base 1 in the embodiment; Figure 7 is Figure 1 a top view of the positioning base 1 in the embodiment; Figure 8 is Figure 1 a front view of the movable positioning component 2 in the embodiment; Figure 9 is Figure 1 a side view of the movable positioning component 2 in the embodiment; Figure 10 is Figure 1 a top view of the movable positioning component 2 in the embodiment.

[0068] The positioning device in the embodiment, as shown in Figure 1 , 2 includes a positioning base 1 and movable positioning components 2 located on both sides of the positioning base 1 respectively, the structures of the movable positioning components 2 on both sides are completely the same, only different in the distribution direction, and the movable positioning components 2 on both sides are respectively named as the first movable positioning component 21 and the second movable positioning component 22. Figure 5As shown, the positioning base 1 is a wedge-shaped body, having a first inclined surface 11 and a second inclined surface 12 respectively located at two sides thereof, the first inclined surface 11 and the second inclined surface 12 are opposite in inclination direction and same in inclination angle, and are symmetrically arranged with respect to the central axis of the positioning base 1. In this embodiment, the positioning base 1 is symmetrically structured with respect to the central axis, so that the first movable positioning component 21 and the second movable positioning component 22 located at two sides of the positioning base 1 can be same in shape, size and other structural parameters, and only need to be processed according to the same parameters during processing, thereby reducing the complexity of processing.

[0069] In combination Figure 1 and Figure 8 As can be seen, one side surface of the second movable positioning component 22 is a fourth inclined surface 221, and the other side surface vertically extends in the working state and is perpendicular to the horizontal plane to serve as a second positioning surface 222; correspondingly, for the first movable positioning component 21, one side surface is a third inclined surface 211, and the other side surface is a first positioning surface 212. The third inclined surface 211 of the first movable positioning component 21 is in abutment with the first inclined surface 11 of the positioning base 1, and the fourth inclined surface 221 of the second movable positioning component 22 is in abutment with the second inclined surface 12 of the positioning base 1, and the first positioning surface 212 and the second positioning surface 222 are used to abut with the side surface of the to-be-positioned component, such as the web plate 7 of the middle beam, which is located between the first positioning surface 212 and the clamping device 8 and between the second positioning surface 222 and the clamping device 8, and the to-be-positioned component is clamped and positioned by the clamping device 8 to form an assembly, such as the middle beam.

[0070] In this way, the first movable positioning component 21 can slide along the direction of the first inclined surface 11, and the second movable positioning component 22 can slide along the direction of the second inclined surface 12. The third inclined surface 211 and the fourth inclined surface 221 can be provided with long strip-shaped protrusions to make the sliding more smooth. When the side surface of the to-be-positioned component contacts the first positioning surface 212 or the second positioning surface 222, a load perpendicular to the first positioning surface 212 and perpendicular to the second positioning surface 222 is respectively applied to the to-be-positioned component on both sides, so that the first movable positioning component 21 and the second movable positioning component 22 do not move relative to the inclined surface, i.e. self-locking is achieved by means of friction, thereby keeping the positioning stable during assembly.

[0071] In detail, take the first movable positioning component 21 as an example. After pressing the component to be positioned, the first movable positioning component 21 will be subjected to a horizontal rightward force. Since the positioning base 1 is fixed, the first movable positioning component 21 will press the positioning base 1, and a vertical pressure will be generated on the contact surface between the two, i.e. the first inclined surface 11 and the third inclined surface 211. The force that the positioning base 1 is subjected to from the first movable positioning component 21 and the force that the first movable positioning component 21 is subjected to from the positioning base 1 are a pair of interaction forces, which are equal in size, opposite in direction, and act on different points. The supporting force that the positioning base 1 provides to the first movable positioning component 21 is vertical to the inclined surface and leftward and upward. The first movable positioning component 21 and the positioning base 1 will have a relative movement or a tendency to move upward along the inclined surface, and then a friction force that hinders the movement will be generated, which is downward along the inclined surface and depends on the friction coefficient between the first inclined surface 11 and the third inclined surface 211 and the pressure between the first movable positioning component 21 and the positioning base 1. The friction coefficient is determined by the material of the contact surface. The movement state of the first movable positioning component 21 will depend on the resultant force, i.e. only the pressure on the contact surface.

[0072] The force analysis of the first movable positioning component 21 is as follows. In the horizontal direction, the first movable positioning component 21 is subjected to the horizontal component of the supporting force of the positioning base 1, the pressure applied to the component to be positioned, and the horizontal component of the friction force. In the vertical direction, the positioning base 1 is subjected to the vertical component of the supporting force, the vertical component of the friction force, and the gravity. As long as the resultant force of the gravity and the vertical component of the friction force is greater than the vertical component of the supporting force, self-locking can be achieved. Therefore, according to the gravity and the friction factor, the angle of the third inclined surface 211 can be set at a suitable angle, so that no matter how large the force applied to the component to be positioned is, the first movable positioning component 21 can remain stationary relative to the positioning base 1. Similarly, as long as the angles of the second inclined surface 12 and the fourth inclined surface 221 are suitable, self-locking can also be achieved for the second movable positioning component 22. In the embodiment, the angles of the first inclined surface 11 and the second inclined surface 12 are selected to be the same.

[0073] In addition, when the assembly containing the component to be positioned is hoisted out after assembly, the assembly moves upward relative to the first positioning surface 212 and the second positioning surface 222, i.e. the component to be positioned generates a vertical upward friction force on the first positioning surface 212 and the second positioning surface 222. Under the action of the friction force, the movable positioning component 2 will not be in a force balance state, and the self-locking is released, i.e. the movable positioning component 2 moves upward along the first inclined surface 11 or the second inclined surface 12 relative to the positioning base 1 until the assembly is completely hoisted out.

[0074] Therefore, compared with the scheme in the prior art, the positioning device in the embodiment adopts the inclined surface matched movable positioning component 2 and positioning base 1 to realize self-locking positioning, which is reliable and can meet the positioning accuracy requirement, and meanwhile, the self-locking is automatically released when the assembly is lifted out, which is beneficial to the smooth lifting out of the assembly.

[0075] Please continue to refer to Figures 11 to 15 , Figure 11 for Figure 5 the front view of the fixed positioning block 13 of the positioning base 1 in the embodiment; Figure 12 for Figure 11 the side view of the fixed positioning block 13 in the embodiment; Figure 13 for Figure 11 the top view of the fixed positioning block 13 in the embodiment; Figure 14 for Figure 5 the front view of the positioning surface adjusting plate 14 of the positioning base 1 in the embodiment; Figure 15 for Figure 14 the side view of the positioning surface adjusting plate 14 in the embodiment.

[0076] As shown in Figure 5 , the positioning base 1 includes the fixed positioning block 13, which is also a wedge-shaped body (shown in Figure 11 ), and the two side surfaces 131 of the fixed positioning block 13 are inclined surfaces with the same inclination angle as the first inclined surface 11 and the second inclined surface 12. The positioning base 1 can also include the positioning surface adjusting plate 14 (shown in Figure 14 ), which is located on the two sides of the fixed positioning block 13 and assembled with the fixed positioning block 13 as the positioning base 1, i.e., the positioning base 1 is a split structure. Specifically, when the to-be-positioned component is assembled, the positioning surface adjusting plate 14 is arranged between the fixed positioning block 13 and the movable positioning component 2, and the positioning surface adjusting plate 14 is a parallelepiped with the same height as the fixed positioning block 13, the bottom surface and the top surface are rectangular, the front side surface and the rear side surface are parallelograms, and the left side surface and the right side surface are inclined surfaces with the same inclination angle as the first inclined surface 11 and the second inclined surface 12. When the fixed positioning block 13 directly contacts the movable positioning component 2, the two side surfaces 131 of the fixed positioning block 13 are the first inclined surface 11 and the second inclined surface 12, respectively; when the fixed positioning block 13 does not directly contact the movable positioning component 2, a certain gap is left between them, and then a plurality of positioning surface adjusting plates 14 can be inserted into the gap according to the requirement, and the outer side surface 141 of the outermost positioning surface adjusting plate 14 is the first inclined surface 11 or the second inclined surface 12. In this way, the distance between the first positioning surface 212 and the second positioning surface 222 can be changed by changing the number of the positioning surface adjusting plates 14, thereby realizing the distance-adjustable function of the positioning device.

[0077] Please refer to Figures 16 to 18 , Figure 16 for Figure 1 The first side plate 4 and the second side plate 5 are fixed to the connecting base 3 in the front view; Figure 17 for Figure 16 Side view; Figure 18 for Figure 16 Top view.

[0078] Depend on Figure 1 As can be seen, the positioning device used in this embodiment also includes a connecting base 3. Both the positioning base 1 and the movable positioning component 2 are disposed on the connecting base 3, which can be used to connect to the assembly platform. Disposing the positioning base 1 and the movable positioning component 2 on the connecting base 3 helps to ensure the positioning effect.

[0079] The first movable positioning component 21 and the second movable positioning component 22 along Figure 1 The first direction shown is distributed as follows: the connecting base 3 is a rectangular plate with a first side 31 and a second side 32 distributed along the second direction shown. It can be seen that the second direction shown is perpendicular to the first direction shown. Figure 1 As can be seen, the positioning device used in this embodiment also includes a first side plate 4 and a second side plate 5. The first side plate 4 is connected to the first side portion 31 of the connecting base 3, and the second side plate 5 is connected to the second side portion 32 of the connecting base 3. Both the first side plate 4 and the second side plate 5 are perpendicular to the plane where the connecting base 3 is located. The connection method can be welding or integral molding. The entire positioning base 1 is disposed between the first side plate 4 and the second side plate 5. The movable positioning component 2 is partially disposed between the first side plate 4 and the second side plate 5, and the remaining part extends out of the first side plate 4 and the second side plate 5 along the first direction so as to fit and abut against the component to be positioned to achieve the positioning function. The front and rear surfaces of the positioning base 1 and the movable positioning component 2 are both in contact with the first side plate 4 and the second side plate 5. This arrangement can restrict the positioning device and prevent the movable positioning component 2 from moving relative to the positioning base 1 along the second direction when the pressure applied to the movable positioning component 2 is too large, thereby further improving the processing and assembly accuracy of the positioning device.

[0080] Please continue to refer to this. Figures 19 to 20 , Figure 19 for Figure 1 Front view of the middle slide bar 6; Figure 20 for Figure 1 Side view of the middle slider 6.

[0081] The positioning device used in this embodiment also includes a slide bar 6 (shown in...). Figure 1 ),Depend on Figure 20 It can be seen that slide bar 6 can specifically be a locating pin. For example... Figure 16The first side plate 4 and the second side plate 5 are respectively provided with a first sliding groove 4a and a first sliding groove 5a on one side along the first direction, the first sliding groove 4a and the first sliding groove 5a are both inclined grooves, the projections along the second direction are coincident and parallel to the first inclined surface 11; correspondingly, the first side plate 4 and the second side plate 5 are respectively provided with a second sliding groove 4b and a second sliding groove 5b on the other side along the first direction, the second sliding groove 4b and the second sliding groove 5b are both inclined grooves, the projections along the second direction are coincident and parallel to the second inclined surface 12. As shown in Figure 8 The movable positioning component 2 is provided with a pin hole 2a, and the slide rod 6 can be inserted into the pin hole 2a and the corresponding first sliding groove 4a, the first sliding groove 5a, or the pin hole 2a and the corresponding second sliding groove 4b, the second sliding groove 5b, and the slide rod 6 is provided as a positioning pin to facilitate the positioning function and reduce the probability of falling off from the positioning device.

[0082] As mentioned above, when the lifting assembly is lifted, the movable positioning component 2 will move upward under the friction of the component to be positioned, at this time, the sliding groove and the slide rod 6 are matched, and under the guidance of the sliding groove, the first movable positioning component 21 and the second movable positioning component 22 will approach each other, thereby reducing the distance between them and generating a spacing with the component to be positioned, so that the lifting is more smooth.

[0083] In the embodiment, the same side plate includes two groups of sliding grooves, and the first side plate 4 is taken as an example for description, the first side plate 4 is provided with two groups of the first sliding groove 4a and the second sliding groove 4b at different heights, and one group of the first sliding groove 4a and the second sliding groove 4b can also achieve the purpose, but multiple groups of the first sliding groove 4a and the second sliding groove 4b can ensure more accurate positioning during movement and increase the mobility of the movable positioning component 2. In the embodiment, two groups of the first sliding groove 4a and the second sliding groove 4b are provided, which can achieve the expected effect under the premise of controllable cost. Obviously, when the sliding groove is provided as two groups, the pin hole 2a on the movable positioning component 2 matched with the first sliding groove 4a, the first sliding groove 5a and the second sliding groove 4b, the second sliding groove 5b should also be provided as two groups at different heights to realize one-to-one positioning.

[0084] Please refer to Figures 21 to 23 , Figure 21 It is a front view when two positioning surface adjusting plates 14 are respectively arranged between the fixed positioning block 13 and the first movable positioning component 21 and between the fixed positioning block 13 and the second movable positioning component 22 of the positioning device in the embodiment; Figure 22 It is a front view when one positioning surface adjusting plate 14 is respectively arranged between the fixed positioning block 13 and the first movable positioning component 21 and between the fixed positioning block 13 and the second movable positioning component 22 of the positioning device in the embodiment; Figure 23This is a front view of the positioning device in this embodiment when there is no positioning surface adjustment plate 14 between the fixed positioning block 13 and the first movable positioning component 21, or between the fixed positioning block 13 and the second movable positioning component 21.

[0085] Furthermore, such as Figure 8 As shown, the movable positioning component 2 has multiple pin holes 2a at the same height, and the upper pin holes 2a correspond one-to-one with the lower pin holes 2a, with the distance between each pin hole 2a being the same. In this embodiment, the length of the positioning surface adjustment plate 14 along the first direction is equal to the distance between two adjacent pin holes 2a. Specifically, the number of positioning surface adjustment plates 14 corresponds to the position of the pin holes 2a into which the slide rod 6 is inserted. When the pin hole 2a into which the slide rod 6 is inserted is located at the outermost position, the number of positioning surface adjustment plates 14 is the maximum, which is two (e.g., ...). Figure 21 As shown); when the slide rod 6 moves inward by one pin hole 2a, the positioning surface adjustment plate 14 decreases by one, becoming one (as shown). Figure 22 As shown); when the slide rod 6 is inserted into the innermost pin hole 2a, the fixed positioning block 13 directly engages with the movable positioning component 2, and the positioning surface adjustment plate 14 is no longer needed (as shown). Figure 23 (As shown). That is, for every time the slide rod 6 moves inward by one pin hole 2a, the positioning surface adjustment plate 14 is reduced by one accordingly, thereby realizing the function of strictly adjusting the distance one-to-one and achieving positioning.

[0086] In this embodiment, the same movable positioning component 2 of the positioning device has three pin holes 2a at the same height, and the number of positioning surface adjustment plates 14 on each side is two. Obviously, the more pin holes 2a are provided, the more positioning surface adjustment plates 14 are required, and the farther the distance between the first positioning surface 212 and the second positioning surface 222 that the positioning device can adjust is. Correspondingly, the space occupied by the positioning device is also larger. The number of pin holes 2a and the number of positioning surface adjustment plates 14 can be set according to specific needs, and the pin holes 2a at appropriate positions can be selected for positioning.

[0087] Can be combined Figure 1 and Figure 8For the first movable positioning component 21, the inner surface 2131 of the movable positioning block 213 (i.e. the side surface close to the positioning base 1) is a slope, which is the third slope 211; the outer surface 2132 of the movable positioning block 213 (i.e. the side surface away from the positioning base 1) is perpendicular to the connecting base 3, and the first positioning plate 214 is fixed to the outer surface 2132 of the movable positioning block 213, the outer surface of the first positioning plate 214 is the first positioning surface 212, and the outer surface can have a plurality of inclined grooves 214a distributed in the height direction; correspondingly, for the second movable positioning component 22, the second movable positioning component 22 comprises a movable positioning block 223 and a first positioning plate 224. The inner surface 2231 of the movable positioning block 223 (i.e. the side surface close to the positioning base 1) is a slope, which is the fourth slope 221; the outer surface 2232 of the movable positioning block 223 (i.e. the side surface away from the positioning base 1) is perpendicular to the connecting base 3, and the first positioning plate 224 is fixed to the outer surface 2232 of the movable positioning block 223, the outer surface of the first positioning plate 224 is the second positioning surface 222, and the outer surface of the first positioning plate 224 has a plurality of inclined grooves 224a distributed in the height direction. The provision of the inclined grooves 214a and 224a can increase the friction, so that the movable positioning component 2 is more easily removed from the self-locking state and moved along the slope.

[0088] Obviously, due to the existence of the sliding grooves, the movable positioning component 2 will not always move upward along the slope, and will remain stationary with the positioning base 1 when the sliding rod 6 slides to the upper part of the first sliding grooves 4a, 5a and the second sliding grooves 4b, 5b, thereby achieving the limiting of the movable positioning component 2. Therefore, it is not necessary to install the movable positioning component 2 every time the assembly is lifted out, which improves the work efficiency. In addition, as the movable positioning component 2 moves, the distance between the first positioning surface 212 and the second positioning surface 222 will decrease, which makes it easy to lift out the assembly. At the same time, the movement of the movable positioning component 2 is realized by relying on the friction, without the need to increase external power devices, which is also conducive to reducing costs.

[0089] The second movable positioning component 2 is provided with a movable positioning block 223 and a first positioning plate 224, which are separate. On the one hand, the first positioning plate 224 and the movable positioning block 223 can be connected by fasteners, and the fasteners themselves can adjust the distance between the first positioning plate 224 and the movable positioning block 223 in the first direction, thereby further increasing the flexibility of adjustment. On the other hand, the separate provision of the first positioning plate 224 also facilitates the machining of the inclined grooves 224a.

[0090] As Figure 8As shown, the movable positioning component 2 further comprises a second positioning plate 215. For the first movable positioning component 21, the bottom end of the first movable positioning component 21 has a protrusion 2133 extending outward (i.e. away from one end of the positioning base 1), the second positioning plate 215 is arranged at the upper end of the protrusion 2133, and the length of the first positioning plate 214 along the first direction is less than the length of the protrusion 2133 and the second positioning plate 215 along the first direction; similarly, for the second movable positioning component 22, the bottom end of the second movable positioning component 22 has a protrusion 2233 extending outward (i.e. away from one end of the positioning base 1), the second positioning plate 225 is arranged at the upper end of the protrusion 2233, and the length of the first positioning plate 224 along the first direction is less than the length of the protrusion 2233 and the second positioning plate 225 along the first direction. In this way, the lower part of the component to be positioned can be positioned and its movement in the vertical direction can be limited, and more accurate positioning can be achieved in cooperation with the first positioning plate 214 and the second positioning plate 224 to ensure assembly accuracy.

[0091] Please refer to Figures 24 to 25 , Figure 24 for Figure 8 the top view of the positioning surface fine adjustment pad 23 in the embodiment; Figure 25 for Figure 8 the side view of the positioning surface fine adjustment pad 23 in the embodiment.

[0092] Looking at Figure 1 and Figure 8 , it can be observed that the movable positioning component 2 further comprises a positioning surface fine adjustment pad 23, which is arranged between the connecting base 3 and the movable positioning block 213 and between the connecting base 3 and the movable positioning block 223, respectively at the bottom of the movable positioning block 213 and the movable positioning block 223, and is connected to the connecting base 3. The positioning surface fine adjustment pad 23 has a certain thickness, and is arranged at the lower part of the movable positioning block 213 and the movable positioning block 223, which is equivalent to the upward movement of the movable positioning component 2 along the inclined surface, i.e. the distance between the first positioning surface 212 and the first positioning surface 222 is shortened. It can be seen that the positioning surface fine adjustment pad 23 can realize small distance adjustment and can further improve the flexibility of adjustment. Obviously, the thickness of the positioning surface fine adjustment pad 23 can be set according to actual needs.

[0093] Please continue to refer to Figures 26 to 28 , Figure 26 for the overall view of the tooling when the positioning device in the embodiment is used to assemble the web 7 of the center sill; Figure 27 for the partial enlarged view of the positioning device in the embodiment placed on the assembly platform 10; Figure 28 for the front view of the positioning device in the embodiment placed on the assembly platform 10.

[0094] By Figure 16It can be seen that the middle part of the bottom of the connecting base 3 is provided with a positioning groove 3a, which facilitates the accurate fixing of the positioning device in the middle of the assembly platform 10 (shown in Figure 28 ) during fixing. The assembly platform 10 can be arranged with multiple positioning devices along the length direction of the web plate 7 to more reliably and stably position the longer web plate 7.

[0095] As shown in Figure 26 , 28 , the clamping device 8 can be matched with the two positioning faces of the movable positioning component 2 to realize the positioning of the web plate 7, that is, the web plate 7 is clamped between the clamping device 8 and the movable positioning component 2. The clamping device 8 can include a pressing bolt which can be rotated to press against the web plate 7. The two side web plates 7 are placed on the movable positioning component 2 respectively, and then the clamping device 8 is used to press the web plate 7 tightly, so that self-locking can be realized. Then the partition plate can be assembled and welded, and the lower cover plate 9 can be installed. When the girder assembly is completed, the hoisting device is used to hoist the girder web plate 7, at this time the movable positioning component 2 is subjected to upward friction, the self-locking is released, the distance between the two end faces is shortened, and the girder web plate 7 is hoisted out smoothly.

[0096] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, several improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
