Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing tooling, specifically to a high-performance rear wheel steering housing fixture for new energy vehicles. Background Technology

[0002] In traditional car design, only the front wheels are responsible for steering, while the rear wheels remain fixed. However, rear-wheel steering technology breaks this traditional design limitation, giving the rear wheels the ability to steer according to driving conditions. This steering can be in the same direction as the front wheels, designed to enhance high-speed stability; it can be in the opposite direction to improve low-speed agility; or it can even be independent of the front wheels, thus significantly improving handling.

[0003] In the production of rear wheel steering housings, frequent transport of the housings is necessary, allowing them to move between multiple workstations for different processing steps. Existing technologies typically use transfer trolleys for this purpose. However, these trolleys lack specific fixtures for the rear wheel steering housings, causing them to easily fall off or rotate during transport. This necessitates recalibration before reassembly at subsequent workstations, impacting the processing efficiency of those stations. Utility Model Content

[0004] In order to overcome the problem that the rear wheel steering housing is prone to falling or overturning during the transportation process in the prior art, this application provides a high-performance rear wheel steering housing clamp for new energy vehicles.

[0005] This application adopts the following technical solution: a high-performance rear wheel steering housing clamp for new energy vehicles, which is set on a transfer platform and includes two uprights and two clamping units, with each upright having a clamping unit;

[0006] The clamping unit includes a base plate, a movable clamping plate, and a fixed clamping plate. The base plate extends vertically and is detachably mounted on the upright. The movable clamping plate and the fixed clamping plate both extend horizontally. The movable clamping plate can slide along the height direction of the base plate, and the fixed clamping plate is fixedly connected to the base plate.

[0007] A tension spring is provided between the movable clamping plate and the fixed clamping plate. When the rear wheel steering housing is clamped between the movable clamping plate and the fixed clamping plate, the tension spring is in a stretched state.

[0008] Optionally, the upright has several through holes, and the base plate has at least one pair of fixing holes. The fixing holes can be coaxially arranged with the through holes. Bolts are inserted into the coaxial fixing holes and through holes, and the bolts are used to lock the base plate.

[0009] Optionally, each of the two base plates has a sliding groove on one side opposite to the other, and each of the two base plates has a receiving groove on its inner side. The sliding groove and the receiving groove are interconnected, and the inner diameter of the receiving groove is larger than the inner diameter of the sliding groove.

[0010] The movable clamp is provided with a connecting rod, and the receiving groove is provided with a slider. One end of the connecting rod is connected to the movable clamp, and the other end of the connecting rod passes through the sliding groove and is connected to the slider. The tension spring is provided in the receiving groove and is located between the inner wall of the receiving groove and the outer wall of the slider.

[0011] Optionally, the inner wall of the slider is fitted with the inner wall of the receiving groove, the slider can slide up and down in the receiving groove, and the connecting rod can slide up and down in the groove.

[0012] Optionally, both the movable clamping plate facing the fixed clamping plate and the fixed clamping plate facing the movable clamping plate have arc-shaped surfaces.

[0013] Optionally, the transfer platform includes a pair of support seats, each of the support seats having a mounting base on its top, and the two uprights are respectively and correspondingly mounted on the two mounting bases.

[0014] Optionally, each of the mounting bases is provided with a through hole extending in a horizontal direction, and a lead screw is inserted through the two through holes. A knob is adapted to be screwed on both ends of the lead screw, and a compression spring is sleeved on the lead screw.

[0015] One of the knobs is located on the outside of one of the bearing seats, and the other knob is located on the outside of the other bearing seat. One end of the compression spring is in contact with the inside of one of the mounting seats, and the other end of the compression spring is in contact with the inside of the other mounting seat.

[0016] Compared to existing technologies, this application utilizes the pulling action of a tension spring on the movable clamping plate to maintain a lower distance between the movable and fixed clamping plates. Furthermore, both the movable and fixed clamping plates have arc-shaped surfaces, which automatically widens the distance between the movable and fixed clamping plates after the rear wheel steering housing is inserted between them. Under the elastic tension of the tension spring, the rear wheel steering housing is reliably clamped and fixed, facilitating its transport. Attached Figure Description

[0022] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] like Figure 1-4 As shown, a high-performance rear wheel steering housing clamp for new energy vehicles is mounted on a transfer platform and includes two uprights 1 and two clamping units 2. Each upright 1 is equipped with a clamping unit 2. The clamping unit 2 includes a base plate 21, a movable clamping plate 22, and a fixed clamping plate 23. The base plate 21 extends vertically and is detachably mounted on the uprights 1. The movable clamping plate 22 and the fixed clamping plate 23 both extend horizontally. The movable clamping plate 22 can slide along the height direction of the base plate 21, and the fixed clamping plate 23 is fixedly connected to the base plate 21. A tension spring 24 is provided between the movable clamping plate 22 and the fixed clamping plate 23. When the rear wheel steering housing is clamped between the movable clamping plate 22 and the fixed clamping plate 23, the tension spring 24 is in a stretched state.

[0024] Under the action of the tension spring 24, there is an elastic force between the movable clamping plate 22 and the fixed clamping plate 23. When the tension spring 24 is in its natural extended state, the distance between the movable clamping plate 22 and the fixed clamping plate 23 is at its minimum and is less than the outer diameter of the rear wheel steering housing. When the rear wheel steering housing is inserted between the movable clamping plate 22 and the fixed clamping plate 23, the movable clamping plate 22 and the fixed clamping plate 23 will be spread apart (i.e., the distance between them will increase). At this time, the tension spring 24 is in an extended state, which can reliably fix the rear wheel steering housing between the movable clamping plate 22 and the fixed clamping plate 23, effectively improving the fixing strength of the rear wheel steering housing on the transfer platform, ensuring that the rear wheel steering housing will not fall off the transfer platform during the transfer process, and also ensuring that the rear wheel steering housing can be transferred to the subsequent workstation in the same posture, thus improving the transfer and assembly efficiency.

[0025] The upright 1 has several through holes 11, and the base plate 21 has at least one pair of fixing holes 211. The fixing holes 211 can be coaxially arranged with the through holes 11. Bolts 12 are inserted into the coaxial fixing holes 211 and through holes 11, and the bolts 12 are used to lock the base plate 21. By aligning the fixing holes 211 with different through holes 11, the installation height of the upright 1 can be adjusted, thereby changing the height of the clamping unit 2, so that the clamp can adapt to different usage environments.

[0026] Each of the two base plates 21 has a sliding groove 212 on one side opposite to the other, and a receiving groove 213 on the inner side of each of the two base plates 21. The sliding groove 212 and the receiving groove 213 are interconnected, and the inner diameter of the receiving groove 213 is larger than the inner diameter of the sliding groove 212. A connecting rod 221 is provided on the movable clamping plate 22, and a slider 222 is provided in the receiving groove 213. One end of the connecting rod 221 is connected to the movable clamping plate 22, and the other end of the connecting rod 221 passes through the sliding groove 212 and is connected to the slider 222. A tension spring 24 is provided in the receiving groove 213 and is located between the inner wall of the receiving groove 213 and the outer wall of the slider 222. The tension spring 24 is set and confined within the receiving groove 213, ensuring that the tension spring 24 can be reliably stretched or reset. Furthermore, under the action of the slider 222 and the connecting rod 221, the movable clamping plate 22 can reliably slide up and down, thus realizing the movable connection between the movable clamping plate 22 and the base plate 21, ensuring that the distance between the movable clamping plate 22 and the fixed clamping plate 23 can be reliably adjusted.

[0027] The inner wall of the slider 222 fits against the inner wall of the receiving groove 213. The slider 222 can slide up and down in the receiving groove 213, and the connecting rod 221 can slide up and down in the sliding groove 212. By reasonably setting the dimensions of the slider 222 and the connecting rod 221, it is ensured that the slider 222 is restricted in the receiving groove 213 and the connecting rod 221 is restricted in the sliding groove 212, thereby ensuring that the movable clamp 22 can move reliably.

[0028] Both the movable clamping plate 22 facing the fixed clamping plate 23 and the fixed clamping plate 23 facing the movable clamping plate 22 are provided with arc-shaped surfaces 223. When it is necessary to clamp the rear wheel steering housing, the rear wheel steering housing can be directly inserted between the movable clamping plate 22 and the fixed clamping plate 23. At this time, under the guidance of the arc-shaped surfaces 223, the horizontal insertion of the rear wheel steering housing can drive the movable clamping plate 22 to move vertically, thereby improving the clamping efficiency.

[0029] The transfer platform includes a pair of support seats 3. Each support seat 3 has a mounting base 31 on its top. Two uprights 1 are respectively and correspondingly mounted on the two mounting bases 31. Each mounting base 31 has a through hole 310 extending in the horizontal direction. A lead screw 32 is inserted into the two through holes 310. A knob 33 is adapted to be screwed on both ends of the lead screw 32. A compression spring 34 is sleeved on the lead screw 32. One knob 33 is located on the outside of one support seat 3, and the other knob 33 is located on the outside of the other support seat 3. One end of the compression spring 34 is in contact with the inside of one mounting base 31, and the other end of the compression spring 34 is in contact with the inside of the other mounting base 31.

[0030] The knob 33 and the lead screw 32 are connected by a thread. The lead screw 32 passes through the mounting base 31 via the through hole 310 (i.e., there is no direct connection between the lead screw 32 and the mounting base 31). Thus, when the knob 33 is rotated, the two mounting bases 31 located between the two knobs 33 can move, meaning the position between the two mounting bases 31 is adjustable. Furthermore, under the elastic force of the compressed spring, the mounting base 31 can tightly engage with the corresponding knob 33, thereby ensuring that the distance between the two bearing bases 3 is fixed after adjustment. By adjusting the distance between the two bearing bases 3, the fixture can adapt to rear wheel steering housings of different sizes. Simultaneously, during clamping, the rear wheel steering housing can be placed between the two clamping units 2, and then the position of the knob 33 can be adjusted to reduce the distance between the two bearing bases 3, allowing the rear wheel steering housing to automatically and completely insert into the clamping unit 2, further improving clamping efficiency.

[0031] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
