Description
Technical Field
[0001] This utility model relates to the field of automotive half-shaft processing technology, and in particular to an automotive half-shaft chamfering device. Background Technology
[0002] The processing of automotive half-shafts requires multiple steps, including the use of a chamfering device to chamfer the half-shaft. For example, a chamfering device for automotive half-shaft processing disclosed in Chinese Patent Application No. CN202220942304.X involves placing both ends of the half-shaft to be chamfered into the connecting groove and the clamping groove, respectively. Then, rotating the locking sleeve adjusts the adjusting rod through the threaded connection, moving it towards the opposite direction and pushing the clamping groove towards the opposite direction, thereby fixing the half-shaft. Furthermore, the stabilizing through-hole stabilizes the adjusting rod during adjustment, achieving a convenient, quick, and stable fixation of the half-shaft. However, it still has the following technical problems.
[0003] The above structure requires rotating multiple locking sleeves to fix the half shaft of the car, which shows that the operation of fixing the half shaft is quite cumbersome. Utility Model Content
[0004] To address the cumbersome fixing operation of the half-shaft in the prior art mentioned in the background section, this utility model provides the following technical solution:
[0005] A chamfering device for automobile half-shafts, including a processing table;
[0006] The machining table includes a chamfering tool for chamfering automobile half-shafts, and a limit station is installed at the upper end of the machining table.
[0007] The limiting platform is symmetrically equipped with clamping components for limiting the movement of the automobile half-shaft.
[0008] The limiting platform is equipped with a reciprocating screw for controlling the two clamping parts to move in opposite directions. A transmission assembly for controlling the rotation of the reciprocating screw is installed in the middle of the reciprocating screw. Push plates for clamping the car half shaft are installed at the left and right ends of the limiting platform to cooperate with the clamping parts. Transmission rods are installed at the left and right ends of the transmission assembly.
[0009] Furthermore, a first bevel gear is installed in the middle of the reciprocating screw.
[0010] Furthermore, the transmission assembly includes a rotating rod, a handwheel is mounted on the front end of the rotating rod, a third bevel gear is sleeved on the front end of the rotating rod, a handle for rotating the third bevel gear is mounted on the outer wall of the third bevel gear, and a second bevel gear is mounted on the rear end of the rotating rod for cooperating with the first bevel gear to control the rotation of the reciprocating screw.
[0011] Furthermore, a fourth bevel gear is installed at one end of the transmission rod to cooperate with the third bevel gear to control the rotation of the transmission rod, and a worm gear is installed at the other end of the transmission rod.
[0012] Furthermore, a threaded sleeve is installed at the middle of the front end of the push plate, and a screw is installed at the middle of the threaded sleeve to cooperate with the threaded sleeve to control the push plate to move back and forth. A worm wheel is installed at the front end of the screw to cooperate with the worm gear to control the rotation of the screw.
[0013] Furthermore, the clamping member includes a lead screw nut for cooperating with a reciprocating lead screw to control the clamping member to move left and right. The upper end of the lead screw nut is equipped with a support block for supporting the automobile half shaft. The middle part of the support block has a slot for limiting the automobile half shaft.
[0014] Furthermore, a clamping rod for clamping the automobile half shaft is installed on one side of the slot, a connecting rod is installed at the front end of the clamping rod, and a limiting seat for limiting the connecting rod is installed at the upper end of the lead screw nut. A spring for controlling the clamping rod to reset is sleeved on the rod body.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] Before chamfering the car half-shaft, the handwheel is first rotated, causing the rotating rod to drive the second bevel gear to rotate. The second bevel gear, in conjunction with the first bevel gear, drives the reciprocating screw to rotate. The reciprocating screw, in conjunction with the screw nut, drives the two clamping parts to move in opposite directions, facilitating the clamping of car half-shafts of different lengths. The car half-shaft is then placed in the slot, and the handle is used to rotate the third bevel gear. The third bevel gear, in conjunction with the fourth bevel gear, controls the transmission rod to rotate, causing the worm gear, in conjunction with the worm wheel, to drive the screw to rotate. As the screw rotates, the threaded sleeve moves backward synchronously to clamp the car half-shaft. Finally, the car half-shaft is chamfered using a chamfering tool. This invention only requires rotating the third bevel gear when clamping the car half-shaft, making the operation simple and quick. Attached Figure Description

[0025] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0026] Please see Figures 1-5 This utility model provides a chamfering device for automobile half-shafts, including a processing table 100. The processing table 100 includes a chamfering cutter 160 for chamfering automobile half-shafts. Chamfering of automobile half-shafts is prior art, therefore, this utility model does not describe the specific structure in detail. A limiting platform 110 is fixedly installed at the upper end of the processing table 100. Clamping members 200 for limiting the automobile half-shaft are symmetrically installed on the left and right sides of the middle of the limiting platform 110. By limiting the automobile half-shaft with clamping members 200, it is convenient for the chamfering cutter 160 to chamfer the automobile half-shaft.
[0027] The limiting stage 110 is internally equipped with a reciprocating screw 120 for controlling the reverse movement of the two clamping members 200, and the helical grooves at both ends of the reciprocating screw 120 rotate in opposite directions. A first bevel gear 121 is fixedly installed in the middle of the reciprocating screw 120. A transmission assembly 130 for controlling the rotation of the reciprocating screw 120 is installed in the middle of the reciprocating screw 120. The transmission assembly 130 includes a rotating rod 131, and a second bevel gear 135 is fixedly installed at the rear end of the rotating rod 131 to cooperate with the first bevel gear 121 to control the rotation of the reciprocating screw 120. A handwheel 132 is fixedly installed at the front end of the rotating rod 131 by an internal hex bolt. The handwheel 132 and the rotating rod 131 are connected by a key, so that when the handwheel 132 is rotated, the rotating rod 131 is rotated synchronously. The front end of the rotating rod 131 is fitted with a third bevel gear 133, and the rear wall of the front handwheel 132 of the rotating rod 131 is not completely close to it. The third bevel gear 133 can rotate on the rod body of the rotating rod 131. Multiple handles 134 for rotating the third bevel gear 133 are fixedly installed on the outer wall of the third bevel gear 133.
[0028] Transmission rods 140 are installed at both ends of the transmission assembly 130. A fourth bevel gear 141 is fixedly installed at one end of the transmission rod 140 near the rotating rod 131. The fourth bevel gear 141 is used to cooperate with the third bevel gear 133 to control the rotation of the transmission rod 140. The rear end of the third bevel gear 133 meshes with the fourth bevel gear 141. When the third bevel gear 133 rotates, the fourth bevel gear 141 synchronously drives the transmission rod 140 to rotate. A worm gear 142 is fixedly installed at the other end of the transmission rod 140.
[0029] Push plates 150 are installed at both ends of the limiting platform 110 to clamp the automobile half-shaft in conjunction with the clamping component 200. A threaded sleeve 151 is fixedly installed at the front middle of the push plate 150. A screw 153 is installed at the middle of the threaded sleeve 151 to control the push plate 150 to move back and forth. The rear end of the screw 153 is machined with an external thread to control the push plate 150 to move back and forth in conjunction with the threaded sleeve 151. A worm wheel 152 is fixedly installed at the front end of the screw 153 to control the rotation of the screw 153 in conjunction with the worm gear 142. When the transmission rod 140 rotates, the worm gear 142 synchronously drives the worm wheel 152 to rotate, so that the screw 153, in conjunction with the threaded sleeve 151, drives the push plate 150 to move backward, so as to clamp the automobile half-shaft in conjunction with the clamping component 200.
[0030] The clamping member 200 includes a screw nut 210 for cooperating with the reciprocating screw 120 to control the left and right movement of the clamping member 200. When the reciprocating screw 120 rotates, the screw nut 210 moves left and right on the rod of the reciprocating screw 120 so as to adjust the distance between the two clamping members 200 according to the different sizes of automobile half shafts.
[0031] A support block 220 for supporting the automobile half-shaft is fixedly installed on the upper end of the lead screw nut 210 by bolts. The support block 220 has a groove 221 for limiting the automobile half-shaft in the middle. A clamping rod 230 for clamping the automobile half-shaft is installed on one side of the groove 221. After one end of the automobile half-shaft is placed in the groove 221, the clamping rod 230 is controlled to press the automobile half-shaft into the groove cavity of the groove 221, so that the clamping rod 230 clamps and limits the automobile half-shaft.
[0032] A connecting rod 231 is fixedly installed at the front end of the clamping rod 230, and a limiting seat 211 for limiting the connecting rod 231 is fixedly installed at the upper end of the lead screw nut 210. A spring 240 for controlling the clamping rod 230 to reset is sleeved on the rod body of the connecting rod 231. A limiting block for limiting the spring 240 is fixedly installed at one end of the connecting rod 231, so that the spring 240 is between the limiting block and the limiting seat 211 on the connecting rod 231. When the push plate 150 moves away from the connecting rod 231, the spring 240 pushes the limiting block at one end of the connecting rod 231 to control the clamping rod 230 away from the car half shaft, so as to facilitate the disassembly of the car half shaft.
[0033] Before chamfering the half-shaft, the handwheel 132 is rotated, causing the rotating rod 131 to drive the second bevel gear 135 to rotate. The second bevel gear 135, in conjunction with the first bevel gear 121, drives the reciprocating screw 120 to rotate. The reciprocating screw 120, in conjunction with the screw nut 210, drives the two clamping parts 200 to move in opposite directions, facilitating the clamping of half-shafts of different lengths. The half-shaft is then placed in the slot 221. The handle 134 is used to rotate the third bevel gear 133. The third bevel gear 133, in conjunction with the fourth bevel gear 141, controls the transmission rod 140 to rotate, causing the worm gear 142, in conjunction with the worm wheel 152, to drive the screw 153 to rotate. As the screw 153 rotates, it drives the threaded sleeve 151 to move backward synchronously, clamping the half-shaft. When disassembling the half-shaft, rotating the third bevel gear 133 in the opposite direction controls the push plate 150 to move away from the half-shaft, facilitating disassembly.
[0034] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
