Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical assembly technical field, and a kind of positioning device and clamp of vehicle hydraulic control unit. BACKGROUND

[0002] Vehicle hydraulic control unit has multiple housings according to model, but has multiple same related parts, in the press-fitting equipment for the press-fitting of these same parts, considering cost and energy efficiency, the same press-fitting equipment needs to be compatible with the press-fitting function of different housings. However, the press-fitting equipment needs to replace the positioning tooling of complete set of clamps when controlling the clamps to clamp different models of housings and other components.

[0003] Since the positioning tooling of the clamp needs to be quickly replaced to improve production efficiency, positioning pin holes are added to the clamp base and the positioning tooling, so that the positioning tooling has two positioning points, greatly improving the machining precision, processing cost and processing time. Since the machining precision is difficult to guarantee, and the two positioning points cannot be repaired once processed. This makes the spare parts of the positioning tooling extremely difficult to manufacture, and the positioning tooling is a high-frequency consumable part. The positioning tooling is frequently replaced and has wear and tear. If the base pin hole is worn, the complete set of clamps needs to be replaced, and the positioning tooling needs to be re-adapted for all models. If the model is increased or the housing is modified, the positioning hole position changes, and the positioning tooling needs to be re-manufactured, which cannot quickly respond and affects production. Therefore, a positioning device and clamp for vehicle hydraulic control unit are needed, which can reduce the adjustment time of the equipment when changing the model and improve the production efficiency. SUMMARY

[0004] In view of the above problems of the prior art, the present application provides a positioning device and clamp for vehicle hydraulic control unit, which can reduce the adjustment time of the equipment when changing the model and improve the production efficiency.

[0005] To achieve the above object, the first aspect of the present application provides a positioning device for a vehicle hydraulic control unit, comprising: a base; a first positioning mechanism, which is arranged on the base and has a first positioning part; a second positioning mechanism, which is slidably connected with the base along a first direction, and can approach and move away from the first positioning mechanism by sliding relative to the base along the first direction, and has a second positioning part; and an adjusting mechanism, which has an adjusting cylinder, an adjusting member and an adjusting head; the adjusting cylinder is fixedly arranged on the second positioning mechanism, and has a through hole extending along the first direction; the adjusting member is arranged in the through hole; the adjusting head is arranged at one end of the adjusting member facing the first positioning mechanism, and is threadedly connected with the adjusting member; the adjusting member can move in the through hole along the first direction; the adjusting member is engaged with the through hole at multiple positions in the through hole, so that the adjusting head is extended out of and retracted into the through hole; and the adjusting head is abutted against the first positioning mechanism when the adjusting head is extended out, so as to adjust the distance between the first positioning part and the second positioning part.

[0006] According to the above, the distance between the second positioning part and the first positioning part can be adjusted by slidably connecting the second positioning mechanism with the base. The distance between the first positioning part and the second positioning part can be positioned by arranging the adjusting mechanism and abutting the adjusting head against the first positioning mechanism. Thus, the adjustment time of the equipment when changing the model can be reduced, and the production efficiency can be improved.

[0007] The adjusting member can be fixed when the adjusting member drives the adjusting head to extend out and retract in by engaging the adjusting member with the through hole at multiple positions. Thus, the distance between the first positioning part and the second positioning part can be adjusted conveniently, so that the adjustment time of the equipment when changing the model can be reduced, and the production efficiency can be improved.

[0008] The adjusting head can be replaced conveniently when the adjusting head is worn out beyond a predetermined degree by threadedly connecting the adjusting head with the adjusting member. Meanwhile, the length of the adjusting head exposed by the adjusting cylinder when the adjusting head is in the extended state can be adjusted by rotating the adjusting head, so that the distance between the first positioning part and the second positioning part when the adjusting head is in the extended state can be adjusted, and the adaptation range of the positioning device can be improved.

[0009] As a possible implementation of the first aspect, the adjusting member includes a first adjusting end and a second adjusting end, the first adjusting end is cylindrical, the second adjusting end is flat, the axis of the first adjusting end coincides with the center line of the second adjusting end, and the adjusting head is arranged on the end face of the first adjusting end; the through hole includes a first hole section, a second hole section and a third hole section connected in sequence along a direction away from the first positioning mechanism, the first hole section and the third hole section are circular holes, the shape of the second hole section is adapted to the shape of the second adjusting end, and the connection positions of the second hole section and the first hole section and the third hole section are respectively provided with a first limiting surface and a second limiting surface facing the first positioning mechanism, and the second adjusting end can rotate around the axis of the first hole section after entering the first hole section.

[0010] As described above, by providing a first limiting surface and a second limiting surface in the through hole, when the second adjustment end is in the second hole section, the end surface of the second adjustment end abuts the second limiting surface, thereby enabling the adjustment member to engage with the through hole and retract the adjustment head into the through hole. Alternatively, when the second adjustment end is in the first hole section, the end surface of the second adjustment end abuts the first limiting surface, thereby enabling the adjustment member to engage with the through hole and extend the adjustment head so as to abut against the first positioning mechanism. Thus, by controlling the second adjustment end to abut against the first limiting surface or the second limiting surface, the extension and retraction of the adjustment head can be controlled, thereby adjusting the distance between the first positioning portion and the second positioning portion.

[0011] As a possible implementation manner of the first aspect, a threaded hole is provided on an end surface of the first adjustment end, and the adjustment head is threadedly connected to the threaded hole.

[0012] As a result, the adjustment head can be easily replaced when it is worn beyond a predetermined extent. Furthermore, the length of the adjustment head exposed from the first adjustment end can be adjusted by rotating the adjustment head, thereby adjusting the distance between the first positioning portion and the second positioning portion when the adjustment head is in the extended state, thereby increasing the adaptability range of the positioning device.

[0013] As a possible implementation manner of the first aspect, the adjustment mechanism further includes: an elastic member, which is disposed in the through hole and drives the adjustment member to move in a direction away from the first positioning mechanism.

[0014] As a possible implementation of the first aspect, the through hole also includes a fourth hole segment, the fourth hole segment is connected to the first hole segment, and a third limiting surface facing away from the first positioning mechanism is provided at the connection position between the fourth hole segment and the first hole segment; the elastic member is a spring, and the elastic member is sleeved on the first adjusting end, with one end abutting against the second adjusting end and the other end abutting against the third limiting surface.

[0015] As described above, by providing an elastic member to drive the adjustment member to move away from the first positioning mechanism, the end surface of the second adjustment end can be kept in contact with the first limit surface or the second limit surface, thereby keeping the adjustment head in the extended state or the retracted state. This can improve the stability of the positioning device.

[0016] As a possible implementation manner of the first aspect, the end surface of the second adjustment end is provided with a groove, and the shape of the groove is adapted to the shape of the end of the screwdriver.

[0017] As described above, by providing a groove on the end surface of the second adjustment end that matches the shape of the screwdriver tip, it is convenient for a worker to use a screwdriver to rotate the second adjustment end. This makes it easier for a worker to operate the adjustment member, causing the second adjustment end to abut against the first limiting surface or the second limiting surface, thereby controlling the extension and retraction of the adjustment head and further adjusting the distance between the first positioning portion and the second positioning portion.

[0018] As a possible implementation of the first aspect, two adjustment mechanisms are provided, and the two adjustment mechanisms are spaced apart along a second direction perpendicular to the first direction, and the two adjustment mechanisms adjust the distance between the first positioning portion and the second positioning portion to be different.

[0019] As described above, because the adjustment mechanism adjusts the distance between the first and second positioning portions to different values, the positioning device can be adapted to workpieces of different sizes, thereby increasing the adaptability of the positioning device. Specifically, when the adjustment heads of all adjustment mechanisms are retracted, the distance between the first and second positioning portions is minimized. As the workpiece size changes, the adjustment heads of the corresponding adjustment mechanisms can be controlled to extend, thereby maintaining the corresponding distance between the first and second positioning portions.

[0020] As a possible implementation of the first aspect, a slide rail is provided on the base, the first positioning mechanism and the second positioning mechanism are slidably connected to the slide rail, and a fastener is provided on the first positioning mechanism to fasten the first positioning mechanism to the slide rail.

[0021] As described above, the position of the first positioning mechanism on the slide rail can be adjusted, and further, when the adjusting head of the adjusting mechanism is in the retracted state, the distance between the first positioning portion and the second positioning portion can be adjusted. Thus, the adaptability range of the positioning device can be further improved.

[0022] A second aspect of the present application provides a clamp comprising the positioning device for the vehicle hydraulic control unit according to any one of the first aspects of the present application.

[0023] As described above, by slidably connecting the second positioning mechanism to the base, the distance between the second positioning portion and the first positioning portion can be adjusted. By providing an adjustment mechanism, the adjustment head of the adjustment mechanism extends and abuts against the first positioning mechanism, thereby adjusting the distance between the first and second positioning portions. This reduces equipment adjustment time when changing models, improving production efficiency.

[0024] These and other aspects of the present invention will become more readily apparent from the following description of the embodiment(s). BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Below, with reference to the accompanying drawings, the specific structure of a possible embodiment of the positioning device 10 in the present application is exemplarily described.

[0037] The positioning device 10 in the present application is a positioning device of a vehicle hydraulic control unit, comprising a base 100, a first positioning mechanism 200, a second positioning mechanism 300 and an adjusting mechanism 400. The first positioning mechanism 200 is arranged on the base 100 and has a first positioning part 220. The second positioning mechanism 300 is slidably connected with the base 100 along a first direction, i.e. a direction approaching or away from the first positioning mechanism 200, and the first positioning mechanism 200 has a second positioning part 320. The adjusting mechanism 400 is arranged on the second positioning mechanism 300 and has an adjusting head 440 which can be extended and retracted. When the adjusting head 440 is extended, it abuts against the first positioning mechanism 200 to adjust the distance between the first positioning part 220 and the second positioning part 320. Thus, by slidably connecting the second positioning mechanism 300 with the base 100, the distance between the second positioning part 320 and the first positioning part 220 can be adjusted. By arranging the adjusting mechanism 400, the adjusting head 440 of the adjusting mechanism 400 is extended to abut against the first positioning mechanism 200, so that the distance between the first positioning part 220 and the second positioning part 320 can be positioned. Thus, the adjustment time of the equipment when changing the model can be reduced, and the production efficiency can be improved.

[0038] In some embodiments, the adjusting mechanism 400 comprises an adjusting cylinder 410 and an adjusting piece 420. The adjusting cylinder 410 is fixedly arranged on the second positioning mechanism 300, and the adjusting cylinder 410 is provided with a through hole 414 extending along the direction approaching or away from the first positioning mechanism 200. The adjusting piece 420 is arranged in the through hole 414 and can move in the through hole 414 along the extension direction of the through hole 414. The adjusting piece 420 is clamped with the through hole 414 at multiple positions in the through hole 414, and the adjusting head 440 is arranged at one end of the adjusting piece 420 facing the first positioning mechanism 200. Thus, by clamping the adjusting piece 420 with the through hole 414 at multiple positions, the adjusting piece 420 can be fixed when driving the adjusting head 440 to extend or retract. Thus, the distance between the first positioning part 220 and the second positioning part 320 can be adjusted conveniently, so that the adjustment time of the equipment when changing the model can be reduced, and the production efficiency can be improved.

[0039] In some embodiments, the adjusting member 420 comprises a first adjusting end 421 and a second adjusting end 422, the first adjusting end 421 is cylindrical, the second adjusting end 422 is flat, the axis of the first adjusting end 421 coincides with the center line of the second adjusting end 422, and the adjusting head 440 is arranged on the end face of the first adjusting end 421. The through hole 414 comprises a first hole section 414a, a second hole section 414b and a third hole section 414c connected in sequence away from the first positioning mechanism 200, the first hole section 414a and the third hole section 414c are circular holes, the shape of the second hole section 414b is matched with the shape of the second adjusting end 422, and the second hole section 414b is provided with a first limiting surface 414e and a second limiting surface 414f facing the first positioning mechanism 200 at the connection positions of the first hole section 414a and the third hole section 414c, respectively. After the second adjusting end 422 enters the first hole section 414a, it can rotate around the axis of the first hole section 414a. Thus, by arranging the first limiting surface 414e and the second limiting surface 414f in the through hole 414, when the second adjusting end 422 is in the second hole section 414b, the end face of the second adjusting end 422 abuts against the second limiting surface 414f, so that the adjusting member 420 and the through hole 414 can be clamped, and the adjusting head 440 can be retracted into the through hole 414. When the second adjusting end 422 is in the first hole section 414a, the end face of the second adjusting end 422 abuts against the first limiting surface 414e, so that the adjusting member 420 and the through hole 414 can be clamped, and the adjusting head 440 can be extended out to abut against the first positioning mechanism 200. Thus, by controlling the second adjusting end 422 to abut against the first limiting surface 414e or the second limiting surface 414f, the extension and retraction of the adjusting head 440 can be controlled, and the distance between the first positioning part 220 and the second positioning part 320 can be adjusted.

[0040] In some embodiments, a threaded hole is arranged on the end face of the first adjusting end 421, and the adjusting head 440 is screwed with the threaded hole. Thus, when the adjusting head 440 is worn out beyond a predetermined degree, the adjusting head 440 can be conveniently replaced. At the same time, the length of the adjusting head 440 exposed from the first adjusting end 421 can be adjusted by rotating the adjusting head 440, so that the distance between the first positioning part 220 and the second positioning part 320 when the adjusting head 440 is in the extended state can be adjusted, and the adaptation range of the positioning device 10 can be improved.

[0041] In some embodiments, the adjusting mechanism 400 further comprises an elastic member 430 arranged in the through hole 414, and the elastic member 430 drives the adjusting member 420 to move away from the first positioning mechanism 200.

[0042] In some embodiments, the through hole 414 further includes a fourth hole section 414d, which is connected to the first hole section 414a. A third limiting surface 414g facing away from the first positioning mechanism 200 is provided at the connection point between the fourth hole section 414d and the first hole section 414a. The elastic member 430 is a spring. Specifically, the elastic member 430 is in a compressed state and is sleeved on the first adjustment end 421, with one end abutting the second adjustment end 422 and the other end abutting the third limiting surface 414g. Thus, by providing the elastic member 430 to drive the adjustment member 420 to move away from the first positioning mechanism 200, the end surface of the second adjustment end 422 can remain abutting the first limiting surface 414e or the second limiting surface 414f, thereby maintaining the adjustment head 440 in an extended or retracted state. This improves the stability of the positioning device 10.

[0043] In some embodiments, the elastic member 430 is a rubber band. Specifically, the elastic member 430 is in a stretched state, with one end of the elastic member 430 fixedly connected to the adjusting member 420 and the other end of the elastic member 430 fixedly connected to the through hole 414 .

[0044] In some embodiments, the end surface of the second adjustment end 422 is provided with a groove 424. The shape of the groove 424 is adapted to the shape of the end of a screwdriver, and can be, for example, a straight, cross, or hexagonal shape. Thus, by providing the groove 424 on the end surface of the second adjustment end 422 that is adapted to the shape of the end of the screwdriver, it is convenient for a worker to use a screwdriver to rotate the second adjustment end 422. This facilitates the worker's operation of the adjustment member 420, causing the second adjustment end 422 to abut against the first limiting surface 414e or the second limiting surface 414f, thereby controlling the extension and retraction of the adjustment head 440, and thereby adjusting the distance between the first positioning portion 220 and the second positioning portion 320.

[0045] In some embodiments, a plurality (e.g., two) of the adjustment mechanisms 400 are provided, and the plurality (e.g., two) of the adjustment mechanisms 400 are spaced apart along a second direction perpendicular to the first direction, and they adjust the distances between the first positioning portion 220 and the second positioning portion 320 to different degrees. Thus, because the adjustment mechanisms 400 adjust the distances between the first positioning portion 220 and the second positioning portion 320 to different degrees, the positioning device 10 can be adapted to workpieces of different sizes, thereby increasing the adaptability of the positioning device 10. Specifically, when the adjustment heads 440 of all the adjustment mechanisms 400 are retracted, the distance between the first positioning portion 220 and the second positioning portion 320 is minimized. As the size of the workpiece changes, the adjustment heads 440 of the corresponding adjustment mechanisms 400 can be controlled to extend, thereby maintaining a corresponding distance between the first positioning portion 220 and the second positioning portion 320.

[0046] In some embodiments, the adjustment mechanism 400 may also be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The adjustment mechanism 400 may control the adjustment head 440 to retract or extend to a predetermined length.

[0047] In some embodiments, the outer circumference of the adjusting member 420 is provided with protruding teeth, and the inner circumference of the through hole 414 is provided with a groove-shaped slide along the extension direction of the through hole. The slide is provided with branches extending away from the first positioning mechanism 200 at multiple positions to form a locking portion. The adjusting member 420 can be moved in a direction away from the first positioning mechanism 200 under the drive of the elastic member 430, so that the teeth on the adjusting member 420 slide along the slide. When the teeth slide into the locking portion, they are locked and connected with the locking portion. In this way, the locking position of the adjusting member 420 and the through hole 414 can be adjusted, and the extension and retraction of the adjusting head 440 from the adjusting cylinder 410 can be controlled, or the length of the adjusting head 440 extending from the adjusting cylinder 410 can be adjusted, that is, the distance between the first positioning portion 220 and the second positioning portion 320 can be adjusted.

[0048] In some embodiments, a slide rail 110 is provided on the base 100, and the first positioning mechanism 200 and the second positioning mechanism 300 are slidably connected to the slide rail 110. The first positioning mechanism 200 is provided with a fastener to fasten the first positioning mechanism 200 to the slide rail 110. Specifically, the fastener can be a bolt or other component. As a result, the position of the first positioning mechanism 200 on the slide rail 110 can be adjusted, and the distance between the first positioning portion 220 and the second positioning portion 320 can be adjusted when the adjustment head 440 of the adjustment mechanism 400 is in the retracted state. In this way, the adaptability range of the positioning device 10 can be further improved.

[0049] The above description provides an exemplary description of possible embodiments of the positioning device 10 in this application. This application also provides a fixture, which includes the positioning device 10. The positioning device 10 can be any possible implementation form of the positioning device 10 described above, which will not be described in detail.

[0050] Below, in conjunction with the accompanying drawings, the specific structure of the positioning device 10 in this application is described in detail in a specific embodiment.

[0051] Figure 1 Schematic diagram of the three-dimensional structure of the positioning device 10 in this application. When the clamp in this application clamps the workpiece in the vehicle hydraulic control unit, the positioning device 10 in this embodiment is used to position the workpiece. Figure 1As shown, the positioning device 10 in the present application includes a base 100, a first positioning mechanism 200, a second positioning mechanism 300 and an adjustment mechanism 400. Among them, the first positioning mechanism 200 is arranged on the base 100, and has a first positioning portion 220, which is used to be plugged and connected with the first positioning hole on the workpiece. The second positioning mechanism 300 is arranged on the base 100, and has a second positioning portion 320, which is used to be plugged and connected with the second positioning hole on the workpiece. The positioning device 10 realizes the positioning of the workpiece through the cooperation between the first positioning portion 220, the second positioning portion 320 and the first positioning hole and the second positioning hole on the workpiece. The adjustment mechanism 400 is arranged on the second positioning mechanism 300, and is used to adjust the distance between the first positioning portion 220 and the second positioning portion 320. Since there are various models of vehicle hydraulic control units, and the distances between the first and second positioning holes on the workpieces of different models of vehicle hydraulic control units vary, when the press-fitting equipment changes the model of the vehicle hydraulic control unit, the positioning device 10 in this embodiment can adjust the distance between the first positioning portion 220 and the second positioning portion 320 through the adjustment mechanism 400. This can reduce the equipment adjustment time when changing the model of the workpiece, thereby improving production efficiency.

[0058] like Figure 2-Figure 4As shown, the regulating tube 410 is provided with a through hole 414 extending in the vertical direction, the regulating member 420 is arranged in the through hole 414, and the regulating head 440 is arranged on the lower end surface of the regulating member 420. The regulating member 420 can move up and down in the through hole 414, so that the regulating head 440 can be extended or retracted by the regulating tube 410. Specifically, the through hole 414 includes a fourth hole section 414d, a first hole section 414a, a second hole section 414b and a third hole section 414c connected in sequence from bottom to top. Wherein, the third hole section 414c is a circular hole, located at the upper part in the second barrel 412, and forming an opening at the upper end of the regulating tube 410. The second hole section 414b is a flat hole, adapted to the shape of the second regulating end 422 described below, and is arranged at the middle position in the second barrel 412. The third hole section 414c and the second hole section 414b form a second limiting surface 414f toward the bottom at the connection position, and the second regulating end 422 described below abuts against the second limiting surface 414f after extending into the second hole section 414b. The first hole section 414a is a circular hole and is divided into two parts, the upper half being located at the bottom of the second barrel 412, and the lower half being a stepped hole in the middle of the first barrel 411. The first hole section 414a and the second hole section 414b form a first limiting surface 414e toward the bottom at the connection position, and the second regulating end 422 described below abuts against the first limiting surface 414e after being pushed into the first hole section 414a by the second hole section 414b and rotating. The fourth hole section 414d is a circular hole, a stepped hole in the lower position for the first barrel 411, and forms an opening at the lower end of the regulating barrel 410. The fourth hole section 414d and the first hole section 414a form a third limiting surface 414g facing upward at the connection position. The diameter of the first hole section 414a is adapted to the diameter of the elastic member 430. The elastic member 430 is arranged in the first hole section 414a, and the lower end of the elastic member 430 abuts against the third limiting surface 414g.

[0059] Figure 5 for Figure 2 Schematic diagram of the three-dimensional structure of the middle adjustment member 420, the elastic member 430 and the adjustment head 440. Figure 5 As shown, the adjustment member 420 includes a first adjustment end 421 and a second adjustment end 422. The first adjustment end 421 is cylindrical, while the second adjustment end 422 is flat. The axis of the first adjustment end 421 coincides with the centerline of the second adjustment end 422. The adjustment head 440 is disposed on the end surface of the first adjustment end 421. Viewed from the bottom up, at the connection point between the first and second adjustment ends 421 and 422, the second adjustment end 422 is exposed from within the first adjustment end 421, forming a fourth limiting surface 423 facing downward. The elastic member 430 is a compressed spring that is mounted on the first adjustment end 421, with the upper end of the elastic member 430 abutting against the fourth limiting surface 423.

[0060] like Figure 5As shown, the upper end face of the second adjusting end 422 is provided with a slot 424 in the shape of a straight line. A straight screwdriver is used to drive the second adjusting end 422 to rotate by inserting the tip of the screwdriver into the slot 424. The lower end face of the first adjusting end 421 is provided with a threaded hole, and the upper end of the adjusting head 440 is arranged in the threaded hole and is screwed with the threaded hole of the first adjusting end 421.

[0061] When the adjusting head 440 needs to be retracted, the second adjusting end 422 is driven to rotate by the screwdriver, so that the second adjusting end 422 is aligned with the second hole section 414b of the through hole 414. At this time, the adjusting member 420 moves upward under the driving of the elastic member 430, so that the upper end face of the second adjusting end 422 abuts against the second limiting face 414f, thereby making the adjusting head 440 retract into the through hole 414 of the adjusting cylinder 410. In this way, the second positioning mechanism 300 can be in the lowest position, and the first positioning part 220 and the second positioning part 320 can be adapted to a type of workpiece.

[0062] When the adjusting head 440 needs to be extended, the second adjusting end 422 is pushed by the screwdriver, so that the second adjusting end 422 is pushed from the second hole section 414b of the through hole 414 into the first hole section 414a. Then, the second adjusting end 422 is rotated by the screwdriver, so that the second adjusting end 422 is disengaged from the second hole section 414b of the through hole 414. After the second adjusting end 422 is loosened, the adjusting member 420 moves upward under the driving of the elastic member 430, so that the upper end face of the second adjusting end 422 abuts against the first limiting face 414e, thereby making the adjusting head 440 extend downward from the lower end of the adjusting cylinder 410. In this way, the adjusting head 440 can abut against the first mounting plate 210, the second mounting mechanism can be pushed to move upward on the slide rail 110, and the first positioning part 220 and the second positioning part 320 can be in positions adapted to another type of workpiece.

[0063] As shown in Figure 1 , Figure 2 The adjusting mechanism 400 is provided with two adjusting mechanisms 400, which are arranged at two side positions of the second mounting plate 310. When the two adjusting mechanisms 400 are in the extended state, the extension lengths of the adjusting heads 440 are different, so that the distances between the corresponding first positioning parts 220 and the second positioning parts 320 are different, that is, different types of workpieces are adapted. In this way, the number of types of workpieces that can be adapted by the positioning device 10 can be increased.
