Abstract
Description
Technical Field
[0001] This invention relates to the field of steering gear fixture technology, and more particularly to a fixture and system for machining steering gear housings. Background Technology
[0002] Steering gears are used to increase the force transmitted from the steering wheel to the steering transmission mechanism and to change the direction of force transmission. They are widely used in many industrial fields. Steering gear housings usually have high precision requirements and need to be ground and processed again after forming. Steering gear surfaces have many holes and bosses.
[0003] Existing clamps mostly clamp by squeezing from both sides towards the center. Because the steering gear housing has many holes and protrusions on its surface, the clamping is unstable. A dedicated clamp for a single steering gear would also increase the cost. Summary of the Invention
[0004] The purpose of this invention is to provide a machining fixture and system for steering gear housings, which aims to solve the problems that existing fixtures mostly clamp the steering gear housing by squeezing from both sides towards the center. Because the steering gear housing has many holes and protrusions on its surface, the clamping is unstable, and a single dedicated steering gear fixture would increase costs.
[0005] To achieve the above objectives, the present invention provides a machining fixture for steering gear housings, comprising a base, a rotating disk, a lifting assembly, a support plate, a rotating component, a clamping plate, a circular slide rail, and multiple clamping components. The clamping plate has placement holes. The rotating disk is rotatably mounted above the base. The lifting assembly is fixed above the rotating disk. The support plate is disposed on the lifting assembly. The rotating component is rotatably mounted on one side of the support plate. The clamping plate is fixed to one side of the support plate. The circular slide rail is fixed to the side of the clamping plate away from the rotating component. Multiple clamping components are arranged on the circular slide rail.
[0006] The clamping component includes a slide block, a clamping seat, a strong spring, and a clamping block. The slide block is slidably mounted on the circular slide rail; the clamping seat is fixed above the slide block; the clamping block is slidably mounted on the clamping seat; the strong spring and the clamping block are fixedly connected, and are also fixedly connected to the clamping seat.
[0007] The clamping component further includes a first telescopic rod and a second telescopic rod. The first telescopic rod is fixed to one side of the clamping seat. The second telescopic rod is slidably connected to the first telescopic rod and is fixedly connected to the clamping block.
[0008] The lifting assembly includes a column, a rack, a support base, a gear, a gear shaft, a torsion ring, and a fixing component. The column is fixed above the rotating disk; the rack is fixed to one side of the column; the support base is slidably mounted on the column; the gear shaft is disposed in the support base; the gear and the gear shaft are fixedly connected and mesh with the rack; the torsion ring is fixed to the side of the gear shaft away from the gear; and the fixing component is disposed in the support base.
[0009] The fixing component includes a locking block, a first spring, and a rebound plate. The locking block is fixed in the support base; the rebound plate is fixed on the gear shaft; the first spring and the rebound plate are fixedly connected, and are also fixedly connected to the support base.
[0010] The rotating component includes a rotating shaft, a roller, and a fixed rod. The roller has multiple through holes. The rotating shaft is rotatably disposed at the end of the support plate. The roller is fixed on the rotating shaft. The fixed rod is slidably mounted on the support plate.
[0011] The aforementioned steering gear housing machining fixture further includes a caster wheel, a counterweight, and a pry bar. The caster wheel is mounted below the base; the counterweight is fixed to the side of the base away from the caster wheel; and the pry bar is fixed to the side of the base near the caster wheel.
[0012] On the other hand, a steering gear housing processing system is applied to the aforementioned steering gear housing processing fixture, comprising a large grinder and a large cutter, wherein the large grinder is disposed on one side of the base; and the large cutter is disposed on the side of the base away from the large grinder.
[0013] This invention discloses a steering gear housing processing fixture. The rotary disk can rotate relative to the base, flexibly changing its angle. A lifting assembly is used to raise or lower the height. One end of a support plate is connected to the lifting assembly, changing its height with the lifting assembly. The other end is provided with a rotating component and a clamping plate. The rotating component can drive the clamping plate to rotate, changing the surface to be ground. The clamping plate and the placement hole are used to place the steering gear workpiece to be clamped. A circular slide rail allows multiple clamping components to move flexibly, clamping the workpiece. The clamping components can slide to avoid bosses, holes, etc. on the steering gear surface, directly clamping onto the steering gear housing, improving clamping stability.
[0014] The sliding block of the clamping member is used to slide relative to the circular slide rail; the clamping seat is used to support the clamping block. When the steering gear housing is placed in, the clamping block and the strong spring are pushed back. After placement, the strong spring rebounds and holds the steering gear housing against it to complete the clamping.
[0015] By using multiple flexible sliding clamping components in coordination, the system avoids protrusions and holes on the steering gear surface and directly clamps onto the steering gear housing, improving clamping stability. The placement angle, height, and machining surface can be adjusted via the rotary table, lifting assembly, and rotating components, facilitating integration with large precision machining equipment and improving the efficiency of grinding, cutting, and other processing. This solves the problem that existing clamps often clamp by squeezing from both sides towards the center, which leads to unstable clamping due to the many holes and protrusions on the steering gear housing surface, while a single dedicated steering gear clamp would increase costs.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0028] First Embodiment
[0029] Please see Figures 1-5 , Figure 1 This is a schematic diagram of the structure of a steering gear housing machining fixture according to the first embodiment of the present invention; Figure 2 This is a partially enlarged view of detail A of a machining steering gear housing fixture according to the first embodiment of the present invention; Figure 3 This is a cross-sectional view based on the gear shaft of a machining steering gear housing fixture according to a first embodiment of the present invention; Figure 4 This is a partially enlarged view of detail B of a machining steering gear housing fixture according to the first embodiment of the present invention; Figure 5 This is a cross-sectional view of a machining steering gear housing fixture based on the support plate according to a first embodiment of the present invention.
[0030] This invention provides a machining fixture for steering gear housings, comprising a base 101, a rotating disk 102, a lifting assembly 103, a support plate 104, a rotating component 105, a clamping plate 106, a circular slide rail 107, and multiple clamping components 108. The clamping plate 106 has placement holes 109. Each clamping component 108 includes a slide block 110, a clamping seat 111, a strong spring 112, a clamping block 113, a first telescopic rod 114, and a second telescopic rod 115. The lifting assembly 103 includes a column 116, a rack 117, a support seat 118, a gear 119, a gear shaft 120, a torsion ring 121, and a fixing component 122. The fixing component 122 includes a locking block 123, a first spring 124, and a return plate 125. The rotating component 105 includes a rotating shaft 126, a roller 127, and a fixing rod 128. The roller 127 has multiple through holes 129.
[0031] The aforementioned solution addresses the problem that existing clamps often clamp by squeezing from both sides towards the center, which leads to unstable clamping due to the numerous holes and protrusions on the steering gear housing surface. Furthermore, using a dedicated steering gear clamp increases costs. Understandably, the aforementioned solution avoids clamping the protrusions and holes on the steering gear housing surface, allowing for flexible clamping. It also allows for multi-degree-of-freedom movement, facilitating integration with large precision machining machines after clamping the steering gear housing and improving processing efficiency.
[0032] In this embodiment, the rotating disk 102 is rotatably mounted above the base 101; the lifting assembly 103 is fixed above the rotating disk 102; the support plate 104 is disposed on the lifting assembly 103; the rotating component 105 is rotatably mounted on one side of the support plate 104; the clamping plate 106 is fixed on one side of the support plate 104; the circular slide rail 107 is fixed on the side of the clamping plate 106 away from the rotating component 105; a plurality of clamping components 108 are arranged on the circular slide rail 107; the rotating disk 102 can rotate relative to the base 101, flexibly changing its angle; the lifting assembly 103 is used to lift or... The height is reduced; one end of the support plate 104 is connected to the lifting assembly 103 and changes height with the lifting assembly 103, and the other end is provided with the rotating part 105 and the clamping plate 106. The rotating part 105 can drive the clamping plate 106 to rotate, changing the surface to be polished; the clamping plate 106 and the placement hole 109 are used to place the steering gear workpiece to be clamped. The circular slide rail 107 allows multiple clamping parts 108 to move flexibly, and the workpiece is clamped by multiple clamping parts 108. The clamping parts 108 can slide to avoid the bosses, holes, etc. on the surface of the steering gear, and are directly clamped on the steering gear housing, improving the clamping firmness.
[0033] The slide block 110 is slidably mounted on the circular slide rail 107; the clamping seat 111 is fixed above the slide block 110; the clamping block 113 is slidably mounted on the clamping seat 111; the strong spring 112 is fixedly connected to the clamping block 113 and to the clamping seat 111; the slide block 110 of the clamping member 108 is used to slide relative to the circular slide rail 107; the clamping seat 111 is used to support the clamping block 113. When the steering gear housing is placed in, the clamping block 113 and the strong spring 112 are pushed back. After placement, the strong spring 112 rebounds and holds the steering gear housing in place to complete the clamping.
[0034] The first telescopic rod 114 is fixed to one side of the clamping seat 111; the second telescopic rod 115 is slidably connected to the first telescopic rod 114 and fixedly connected to the clamping block 113; the first telescopic rod 114 and the second telescopic rod 115 are used to cooperate with the movement of the clamping block 113 and to restrict the force spring 112 so that its elastic force remains linear.
[0035] Secondly, the column 116 is fixed above the rotating disk 102; the rack 117 is fixed to one side of the column 116; the support base 118 is slidably mounted on the column 116; the gear shaft 120 is disposed in the support base 118; the gear 119 is fixedly connected to the gear shaft 120 and meshes with the rack 117; the torsion ring 121 is fixed to the side of the gear shaft 120 away from the gear 119; the fixing member 122 is disposed in the support base 118; the support plate 104 is mounted on one side of the support base 118, which can drive the support plate 104 to slide up and down relative to the column 116; the torsion ring 121 is used to rotate the gear shaft 120 and the gear 119 from the outside, so that the gear 119 rotates on the rack 117, thereby driving the support base 118 to slide up and down; the gear 119 can be finely adjusted in height to make the clamping member 108 height accurate.
[0036] Furthermore, the locking block 123 is fixed in the support base 118; the spring plate 125 is fixed on the gear shaft 120; the first spring 124 and the spring plate 125 are fixedly connected, and are also fixedly connected to the support base 118; the width of the locking block 123 is smaller than the width of the rack 117. After the gear shaft 120 is pressed, the gear 119 only meshes with the rack 117, and then rotates to adjust the height. When released, the gear shaft 120 pops out under the action of the first spring 124 and the spring plate 125, meshes with the rack 117, and is locked on the locking block 123, thereby preventing it from slipping after the height adjustment.
[0037] Finally, the rotating shaft 126 is rotatably disposed at the end of the support plate 104; the roller 127 is fixed on the rotating shaft 126; the fixing rod 128 is slidably mounted on the support plate 104; one end of the roller 127 is fixed with the clamping plate 106, the rotating shaft 126 and the roller 127 can rotate relative to the support plate 104 to drive the clamping plate 106 to rotate, and after clamping, the processing surface is adjusted. The fixing rod 128 can be inserted into the adjacent through hole 129 to fix the roller 127.
[0038] During the processing of the steering gear housing using this device, the sliding block 110 of the clamping member 108 is slid to avoid protrusions, holes, etc. on the surface of the steering gear. After the steering gear housing is placed in, the strong spring 112 rebounds, holding the steering gear housing in place. Then, the torsion ring 121 is pressed to push the gear 119 out of the locking block 123. After being pushed out, it is rotated to precisely adjust the height. After being released, the gear shaft 120 is ejected under the action of the first spring 124 and the return plate 125, meshing with the rack 117 while locking onto the locking block 123 to prevent slippage after height adjustment. Then, the fixing rod 128 is pulled out, the roller 127 is rotated to adjust the processing surface, and after adjustment, the gear shaft 120 is released. The fixing rod 128 is inserted into the adjacent through hole 129 to fix the roller 127. Then, the steering gear housing is precision machined. This device uses multiple flexible sliding clamping parts 108 to cooperate with each other, avoiding bosses and holes on the steering gear surface, and directly clamping onto the steering gear housing, improving the clamping firmness. The placement angle, height and processing surface can be adjusted by the rotating disk 102, the lifting assembly 103 and the rotating part 105, which is convenient for cooperation with large precision machining equipment and improves the processing efficiency of grinding, cutting and other processes. This solves the problem that existing clamps mostly clamp from both sides to the center, because the steering gear housing surface has many holes and bosses, which will lead to unstable clamping, and a single steering gear-specific clamp will increase the cost.

[0042] The caster wheel 201 is installed below the base 101; the counterweight 202 is fixed to the side of the base 101 away from the caster wheel 201; the pry bar 203 is fixed to the side of the base 101 near the caster wheel 201; the caster wheel 201 provides mobility for easy movement to the processing machine; the counterweight 202 is used to fix and lock the device to prevent movement; when movement is required, the base 101 is tilted at a certain angle by the pry bar 203 to lift the counterweight 202 off the ground, and then moved, thus facilitating movement to the processing machine.

Similarly, the large cutting machine 302 can be used for cutting. Through the cooperation of the clamping device and the large grinding machine 301 and the large cutting machine 302, manual processing is replaced, and the processing efficiency of the steering gear housing is improved.
