Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive shaft processing technology, and in particular to a multi-station automotive shaft processing positioning fixture. Background Technology
[0002] An automotive axle is a shaft that bears both bending moment and torque. It is a key component connecting parts and main components of a product. The axle itself rotates, supporting parts and transmitting power. Gears, pulleys, and other shaft-mounted parts are generally mounted on the axle. Conventional devices are time-consuming, labor-intensive, and inconvenient when fixing automotive axles of different specifications, thus affecting the device's fixing effect on the automotive axle.
[0003] Existing technology CN218657826U discloses a multi-station automotive shaft machining positioning fixture, including a mounting base, mounting holes, a U-shaped frame, a knob, a double-acting lead screw, sliding plates, and triangular chucks. The operator fixes the U-shaped frame and its auxiliary mechanisms in a designated machine tool work area by aligning the mounting base with the mounting holes. Then, according to the length of the automotive shaft, the operator rotates the double-acting lead screw via the knob. The rotation of the double-acting lead screw drives two sliding plates to move simultaneously along a dovetail slide. When the double-acting lead screw rotates clockwise, the two sliding plates move closer together; conversely, when it rotates counterclockwise, they move further apart. The knob is then stopped after the distance between the two sliding plates is adjusted to match the automotive shaft to be machined. The operator places the automotive shaft to be machined between the two triangular chucks and then rotates the triangular chucks, causing the jaws on the chucks to clamp and fix the automotive shaft, thus affecting the device's fixing effect on the automotive shaft.
[0004] During normal use, when machining a fixed rotating shaft, the debris generated during machining can easily fall off and adhere to the bidirectional lead screw. When the bidirectional lead screw drives the sliding plate to move, the debris on the bidirectional lead screw can easily get stuck between the bidirectional lead screw and the sliding plate, thus affecting the movement of the sliding plate and consequently affecting the performance of the device. Utility Model Content
[0005] The purpose of this utility model is to provide a multi-station automotive shaft machining positioning fixture, which solves the problem that when machining a fixed shaft in the prior art, the debris generated during machining easily falls off and adheres to the bidirectional lead screw. When the bidirectional lead screw rotates to drive the sliding plate to move, the debris on the bidirectional lead screw is easily stuck between the bidirectional lead screw and the sliding plate, thus affecting the movement of the sliding plate and thus affecting the use effect of the device.
[0006] To achieve the above objectives, this utility model provides a multi-station automotive shaft machining positioning fixture, including a base and a structural device. The structural device includes a sliding plate, a triangular chuck, a slider, a block, a bidirectional lead screw, a rotating block, a rotating cylinder, a seat, and a limiting component. The slider is slidably mounted on one side of the base. The bidirectional lead screw is rotatably connected to the base and threadedly connected to the slider. The rotating block is fixedly mounted on the side of the bidirectional lead screw away from the slider. The block is slidably connected to the base and fixedly connected to the slider. The sliding plate is fixedly mounted on the side of the block away from the slider. The rotating cylinder is rotatably mounted on the side of the sliding plate away from the base. The triangular chuck is fixedly connected to the rotating cylinder and rotatably connected to the sliding plate. The seat is fixedly mounted on the side of the base away from the rotating cylinder. The limiting component is connected to the sliding plate and the rotating cylinder.
[0007] The limiting component includes a driven wheel and a fixing member. The driven wheel is fixedly connected to the rotating drum and rotatably connected to the sliding plate. The fixing member is connected to the driven wheel and to the sliding plate.
[0008] The fixing component includes a fixing block and a driving component. The fixing block is slidably connected to the sliding plate and meshes with the driven wheel. The driving component is connected to the sliding plate and to the fixing block.
[0009] The driving component includes a driving screw and a driving block. The driving block is rotatably connected to the sliding plate and is located on the side of the sliding plate away from the rotating cylinder. The driving screw is fixedly connected to the driving block and threadedly connected to the fixed block.
[0010] The structural device further includes a limiting rod and a limiting cylinder. The limiting cylinder is fixedly connected to the slider and is located on the side of the slider closer to the block. The limiting cylinder is slidably connected to the limiting rod and fixedly connected to the base.
[0011] This utility model discloses a multi-station automotive shaft machining positioning fixture. A rotating drive block rotates on a sliding plate, driving a drive screw to rotate. The drive screw meshes with the drive block, driving a fixed block to move on the sliding plate, causing the sliding plate to abut against the driven wheel, thus limiting the rotation angle of the driven wheel and consequently limiting the rotation angle of the rotary drum and the triangular chuck. Rotating the rotating block drives a bidirectional lead screw to rotate on a base. The bidirectional lead screw's rotation drives a slider, moving the block on the base. The block's movement causes the sliding plate and the triangular chuck to move. The block, slider, base, and sliding plate work together to block debris generated during machining, preventing debris from affecting the movement of the sliding plate and thus improving the device's performance.

Detailed Implementation
[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The first embodiment of this application is as follows:
[0021] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the multi-station automotive shaft machining positioning fixture according to the first embodiment of this utility model. Figure 2 This is a schematic diagram of the structure of the bidirectional lead screw and rotating block of this utility model. Figure 3 This is a schematic diagram of the structure of the driven wheel and the fixing block of this utility model. This utility model provides a multi-station automotive axle machining positioning fixture, including a base 101 and a structural device. The structural device includes a sliding plate 102, a triangular chuck 103, a slider 104, a block 105, a two-way lead screw 106, a rotating block 107, a rotating cylinder 108, a seat 109, and a limiting component. The limiting component includes a driven wheel 110 and a fixing member. The fixing member includes a fixing block 111 and a driving component. The driving component includes a driving lead screw 112 and a driving block 113. The aforementioned solution solves the problems encountered in the development of existing technologies. When machining a fixed rotating shaft, the debris generated during machining easily falls off and adheres to the bidirectional lead screw 106. When the bidirectional lead screw 106 drives the sliding plate 102 to move, the debris on the bidirectional lead screw 106 easily gets stuck between the bidirectional lead screw 106 and the sliding plate 102, thus affecting the movement of the sliding plate 102 and thus affecting the performance of the device. It is understood that the aforementioned solution can be used when machining a fixed rotating shaft in the prior art, where the debris generated during machining easily falls off and adheres to the bidirectional lead screw 106.
[0022] In this specific embodiment, by rotating the rotating block 107, the bidirectional lead screw 106 is driven to rotate on the base 101. When the bidirectional lead screw 106 rotates, it drives the slider 104 to move the block 105 on the base 101. When the block 105 moves, it drives the sliding plate 102 and the triangular chuck 103 to move. The block 105, the slider 104, the base 101, and the sliding plate 102 cooperate to block the debris generated during processing, preventing the debris from affecting the movement of the sliding plate 102, thereby improving the performance of the device.
[0023] The slider 104 is slidably mounted on one side of the base 101. The bidirectional lead screw 106 is rotatably connected to the base 101 and threadedly connected to the slider 104. The rotating block 107 is fixedly mounted on the side of the bidirectional lead screw 106 away from the slider 104. The block 105 is slidably connected to the base 101 and fixedly connected to the slider 104. The sliding plate 102 is fixedly mounted on the side of the block 105 away from the slider 104. The rotating cylinder 108 is rotatably mounted on the side of the sliding plate 102 away from the base 101. The triangular chuck 103 is fixedly connected to the rotating cylinder 108 and rotatably connected to the sliding plate 102. The seat 109 is fixedly mounted on the... The base 101 is located away from the rotating cylinder 108. The limiting component is connected to the sliding plate 102 and the rotating cylinder 108. The bottom of the base 101 has a groove, and the end of the base 101 has a rotating hole. There are multiple blocks 105 and multiple sliders 104. The left side of each slider 104 has a through threaded hole, and the through threaded holes of two sliders 104 are opposite. The upper outer side of each slider 104 is slidably connected to the groove of the base 101. The front and rear ends of each slider 104 are fixedly connected to the bottom ends of two blocks 105, respectively. The outer side of the bidirectional lead screw 106 has an external thread, and the external threads at both ends are opposite. The external thread of the bidirectional lead screw 106 is connected to the slider 104. The system includes a through-threaded hole connection, with the end of the bidirectional lead screw 106 fixedly connected to the rotating block 107 via a rotating hole in the base 101. The end of the sliding plate 102 is hollow, and there are multiple sliding plates 102. The lower outer part of the sliding plate 102 is fixedly connected to the top of two blocks 105. There are multiple rotating cylinders 108, with the outer horizontal end of each rotating cylinder 108 rotatably connected to the inner side of the sliding plate 102. There are multiple triangular chucks 103, located at the horizontal end of each rotating cylinder 108. There are multiple bases 109, with mounting holes at the horizontal end of each base 109. Bolts are fixed to the machine tool through these mounting holes. The vertical end of the base 109... The top is fixedly connected to the bottom of the vertical end of the base 109. Multiple limiting components restrict the rotation angle of the rotating cylinder 108 on the sliding plate 102. By rotating the rotating block 107, the bidirectional lead screw 106 is driven to rotate on the base 101. When the bidirectional lead screw 106 rotates, it drives the slider 104 to move the block 105 on the base 101. As the block 105 moves, it drives the sliding plate 102 and the triangular chuck 103 to move. The block 105, slider 104, base 101, and sliding plate 102 cooperate to block debris generated during processing, preventing debris from affecting the movement of the sliding plate 102.This improves the effectiveness of the device.
[0024] Secondly, the driven wheel 110 is fixedly connected to the rotating drum 108 and rotatably connected to the sliding plate 102; the fixing member is connected to the driven wheel 110 and the sliding plate 102. The inner side of the sliding plate 102 is designed with a rotating groove, and the outer side of the driven wheel 110 is designed with teeth. The inner side of the driven wheel 110 is fixedly connected to the outer side of the horizontal end of the rotating drum 108. The rotation angle of the driven wheel 110 is limited by the fixing member. The driven wheel 110 drives the rotating drum 108 to rotate on the sliding plate 102, and the rotation angle is limited.
[0025] Meanwhile, the fixed block 111 is slidably connected to the sliding plate 102 and engages with the driven wheel 110; the driving component is connected to the sliding plate 102 and the fixed block 111. The sliding plate 102 has a sliding cavity inside and a rotating hole at its outer front end. The fixed block 111 has teeth on its inner side, and the teeth of the fixed block 111 engage with the teeth of the driven wheel 110. The driving component drives the fixed block 111 to move on the sliding cavity of the sliding plate 102 through the rotating hole of the sliding plate 102. By driving the fixed block 111 to move on the sliding plate 102, the sliding plate 102 abuts against the driven wheel 110, thereby limiting the rotation angle of the driven wheel 110.
[0026] Then, the drive block 113 is rotatably connected to the sliding plate 102 and is located on the side of the sliding plate 102 away from the rotating cylinder 108; the drive screw 112 is fixedly connected to the drive block 113 and threadedly connected to the fixed block 111. The left end of the fixed block 111 is designed with an internal threaded hole, and the outer side of the drive screw 112 is designed with an external thread. The external thread of the drive screw 112 meshes with the internal threaded hole of the drive block 113. The left end of the drive block 113 is designed with a groove. The outer side of the drive block 113 is rotatably connected to the rotating hole of the sliding plate 102. The outer side of the closed end of the drive block 113 is fixedly connected to the end of the drive screw 112. By rotating the drive block 113 on the sliding plate 102, the drive block 113 drives the drive screw 112 to rotate. The drive screw 112 meshes with the drive block 113, thereby driving the fixed block 111 to move.
[0027] When using the multi-station automotive shaft machining positioning fixture of this embodiment, the drive block 113 rotates on the sliding plate 102. During rotation, the drive block 113 drives the drive screw 112 to rotate. The drive screw 112 meshes with the drive block 113, driving the fixed block 111 to move on the sliding plate 102, causing the sliding plate 102 to abut against the driven wheel 110, thus limiting the rotation angle of the driven wheel 110, and consequently limiting the rotation angle of the rotary drum 108 and the triangular chuck 103. The rotating block 107 drives the bidirectional lead screw 106 to rotate on the base 101. When the bidirectional lead screw 106 rotates, it drives the slider 104 to move the block 105 on the base 101. When the block 105 moves, it drives the sliding plate 102 and the triangular chuck 103 to move. The block 105, slider 104, base 101 and sliding plate 102 cooperate to block the debris generated during processing, so as to avoid the debris affecting the movement of the sliding plate 102, thereby improving the use effect of the device.
[0028] The second embodiment of this application is as follows:
[0029] Please see Figure 4 and Figure 5 , Figure 4 This is a structural schematic diagram of the base and limiting rod of this utility model. Figure 5 This is a schematic diagram of the slider and limiting cylinder of this utility model. Based on the first embodiment, the structural device of this embodiment further includes a limiting rod 201 and a limiting cylinder 202.
[0030] In this specific embodiment, the slider 104 drives the limiting cylinder 202 to move on the limiting rod 201, thereby limiting the movement angle of the slider 104 and improving the stability of the slider 104 during movement.
[0031] The limiting cylinder 202 is fixedly connected to the slider 104 and located on the side of the slider 104 near the block 105. The limiting cylinder 202 is slidably connected to the limiting rod 201 and fixedly connected to the base 101. The slider 104 has mounting holes on both sides of its horizontal end. There are multiple limiting cylinders 202, and each limiting cylinder 202 has a sliding hole at its end. The outer side of the limiting cylinder 202 is fixedly connected to the mounting hole of the slider 104. There are multiple limiting rods 201, and the end of each limiting rod 201 is fixedly connected to the inner side of the vertical end of the base 101 through the sliding hole of the limiting cylinder 202. The slider 104 drives the limiting cylinder 202 to move on the limiting rod 201, thereby limiting the movement angle of the slider 104 and improving the stability of the slider 104 during movement.
[0032] When using the multi-station automotive shaft machining positioning fixture of this embodiment, the slider 104 drives the limiting cylinder 202 to move on the limiting rod 201, thereby limiting the movement angle of the slider 104 and improving the stability of the slider 104 during movement.
