Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to a grinding device for automotive parts processing. Background Technology

[0002] Among automotive parts, shafts are among the most frequently used components, typically for transmitting power and bearing loads. After machining, shafts require surface polishing to increase their smoothness. However, during shaft machining, workers typically hold the shaft's two end faces and bring its radial side close to a belt sander. The belt sander then polishes the radial end faces. Because the belt size is fixed while shaft lengths vary, workers must not only rotate the shaft but also move it horizontally. This operation is time-consuming and labor-intensive, and the sanding belt can easily cause abrasions to the workers' hands, posing a safety hazard. Therefore, a polishing device for automotive parts machining is needed to solve these problems. Summary of the Invention

[0003] In view of the above situation and to overcome the shortcomings of the prior art, this device provides a grinding device for processing automotive parts. When processing axle-type automotive parts, the device eliminates the need for workers to hold the parts manually, thus improving the safety of worker operation. At the same time, the device has the advantage of high grinding efficiency.

[0004] The purpose of this utility model is to provide a grinding device for processing automotive parts, including a base, a belt sander fixedly installed on the top of the base, a base fixedly connected to the top of the base, the base being located on one side of the belt sander, a movable plate slidably connected to the top of the base, the movable plate sliding back and forth controlled by a propulsion mechanism fixedly connected to the top of the base, a translation frame and a reciprocating rotation mechanism respectively connected to the top of the movable plate, the translation frame slidably connected to the movable plate, the reciprocating rotation mechanism fixedly connected to the movable plate, the translation frame sliding on the top of the movable plate under the control of the reciprocating rotation mechanism, a clamping mechanism fixedly connected to one side of the translation frame, the clamping mechanism and the translation frame working together to clamp both ends of shaft-type parts.

[0005] Furthermore, a first mounting frame and a second mounting frame are fixedly connected to the left and right sides of the rear end of the translation frame, respectively. The first mounting frame is connected to the clamping mechanism, and the second mounting frame is connected to the reciprocating rotation mechanism. A slider is fixedly connected to the bottom of the translation frame, and a groove that cooperates with the slider is opened on the top of the moving plate. The slider and the groove are slidably connected.

[0006] Furthermore, the clamping mechanism includes an electric telescopic rod, which is fixedly installed at the front end of the translation frame. A sliding shaft is splined on the surface of the first mounting frame. One end of the sliding shaft is rotatably connected to a first clamping block, and the other end of the sliding shaft and the extended end of the electric telescopic rod are fixedly connected to a synchronization plate.

[0007] Furthermore, the reciprocating rotation mechanism includes a vertical plate, a lead screw sleeve fixedly connected to the rear end of the vertical plate, a lead screw threadedly connected to the lead screw sleeve, a second clamping block fixedly connected to one end of the lead screw, the second clamping block being rotatably connected to the second mounting frame, a spherical universal joint fixedly connected to the other end of the lead screw, a connecting rod fixedly connected to the surface of the spherical universal joint, a rotating rod hinged to the other end of the connecting rod, and the rotating rod being fixedly connected to the output end of the first motor fixedly connected to the front end of the vertical plate.

[0008] Furthermore, the propulsion mechanism includes a handwheel, with a threaded rod coaxially fixedly connected to the rear end of the handwheel. The threaded rod is rotatably mounted in a mounting groove on the top of the base, and a threaded sleeve is threadedly connected to the surface of the threaded rod. The threaded rod is fixedly connected to the bottom of the moving plate.

[0009] Furthermore, the front end of the moving plate is provided with a receiving groove that cooperates with the belt sander.

[0010] The working principle and usage principle of this utility model are as follows: The device places both ends of the axle-type automotive parts between the first clamping block and the second clamping block. The clamping mechanism controls the first clamping block to move toward the second clamping block, thereby fixing the axle-type automotive parts. In the reciprocating rotation mechanism, the second clamping block is rotated by the combination of a lead screw, lead screw sleeve, connecting rod and rotating rod. The rotating second clamping block drives the axle-type automotive parts clamped between the first clamping block and the second clamping block to rotate axially. The movement of the second clamping block drives the translation frame to slide on the top of the moving block synchronously through the second mounting frame, thereby causing the axle-type automotive parts clamped between the first clamping block and the second clamping block to move laterally. At this time, the axle-type automotive parts clamped between the first clamping block and the second clamping block can slide laterally reciprocally while rotating. Then, the pushing mechanism controls the moving plate to push the axle-type automotive parts toward the belt sander. The friction generated between the sander belt and the radial surface of the axle-type automotive parts achieves the surface grinding of the axle-type automotive parts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Compared with the prior art, this utility model can control the axle-type automotive parts to reciprocate laterally while rotating during the grinding process, which facilitates uniform grinding of the surface of the axle-type automotive parts with a longer length by the belt sander, and effectively improves the grinding efficiency of the axle-type automotive parts.

[0013] 2. Compared with the prior art, the present invention can effectively improve the fixing and grinding effect of axle-type automotive parts by combining the pushing mechanism and the clamping mechanism, thereby increasing the stability and safety of grinding axle-type automotive parts.

[0019] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0020] according to Figures 1 to 4 As shown, a grinding device for processing automotive parts includes a base 1, a belt sander 2 fixedly mounted on the top of the base 1, a base 3 fixedly connected to the top of the base 1, the base 3 being located on one side of the belt sander 2, a movable plate 4 slidably connected to the top of the base 3, the movable plate 4 being controlled to slide back and forth by a pushing mechanism 8 fixedly connected to the top of the base 3, a translation frame 5 and a reciprocating rotation mechanism 7 respectively connected to the top of the movable plate 4, the translation frame 5 being slidably connected to the movable plate 4, the reciprocating rotation mechanism 7 being fixedly connected to the movable plate 4, the translation frame 5 sliding on the top of the movable plate 4 under the control of the reciprocating rotation mechanism 7, a clamping mechanism 6 fixedly connected to one side of the translation frame 5, the clamping mechanism 6 and the translation frame 5 being used to clamp both ends of shaft-type parts.

[0021] In specific implementation, the belt sander 2 can be a vertical belt sander 2. Specifically, one side of the sanding belt of the belt sander 2 is vertically set. The base 3 is set on the vertical sanding belt side of the vertical belt sander 2. Two T-shaped blocks are fixedly connected to the bottom of the moving plate 4. Two T-shaped grooves are opened at the top of the base 3 corresponding to the two T-shaped blocks. The moving plate 4 and the base 3 are slidably connected through the T-shaped blocks and T-shaped grooves. The moving plate 4 is moved towards the belt sander 2 by manually operating the propulsion mechanism 8, so that the axle-type automotive parts fixed on the moving plate 4 by the clamping mechanism 6 come into contact with the surface of the sanding belt. The surface of the axle-type automotive parts is polished by the sanding belt. The combination of the clamping mechanism 6 and the propulsion mechanism 8 can avoid the problem of workers having to hold both ends of the parts and close to the sanding belt when polishing axle-type automotive parts, thus improving the safety of workers when polishing axle-type automotive parts. A translation frame 5 is slidably set on the top of the moving plate 4. The sliding frame 5, controlled by the reciprocating rotation mechanism 7, can slide left and right on the top surface of the sliding plate 4. The left and right reciprocating sliding of the sliding frame 5, in conjunction with the clamping mechanism 6, drives the axle-type automotive parts clamped between the sliding frame 5 and the clamping mechanism 6 to slide left and right. This facilitates the control of the left and right displacement of the axle-type automotive parts when grinding long axle-type automotive parts, thereby facilitating the transverse reciprocating grinding of the radial surface of the axle-type parts. The reciprocating rotation mechanism 7 can also control the axial rotation of the axle-type automotive parts clamped between the clamping mechanism 6 and the sliding frame 5. The contact between the axially rotating axle-type automotive parts and the sanding belt can perform circumferential grinding of the axial and radial surfaces. This allows for simultaneous rotation and control of the axial displacement of the axle-type automotive parts during grinding, improving the grinding efficiency of axle-type automotive parts.

[0022] Furthermore, a first mounting frame 51 and a second mounting frame 52 are fixedly connected to the left and right sides of the rear end of the translation frame 5, respectively. The first mounting frame 51 is connected to the clamping mechanism 6, and the second mounting frame 52 is connected to the reciprocating rotation mechanism 7. A slider 53 is fixedly connected to the bottom of the translation frame 5, and a groove 54 that cooperates with the slider 53 is opened on the top of the moving plate 4. The slider 53 and the groove 54 are slidably connected.

[0023] In specific implementation, the rear end of the translation frame 5 is connected to the clamping mechanism 6 and the reciprocating rotation mechanism 7 through the first mounting frame 51 and the second mounting frame 52 respectively. The clamping mechanism 6 and the translation frame 5 can clamp axle-type automotive parts. The reciprocating rotation mechanism 7 can control the translation frame 5 to slide left and right on the top of the moving plate 4, thereby driving the axle-type automotive parts clamped between the clamping mechanism 6 and the translation frame 5 to perform left and right translation and grinding. The translation frame 5 is slidably connected to the moving plate 4 through the bottom slider 53, which increases the stability of the connection between the translation frame 5 and the moving plate 4.

[0024] Furthermore, the clamping mechanism 6 includes an electric telescopic rod 61, which is fixedly installed at the front end of the translation frame 5. A sliding shaft 63 is splinedly connected to the surface of the first mounting frame 51. One end of the sliding shaft 63 is rotatably connected to a first clamping block 64, and the other end of the sliding shaft 63 is fixedly connected to a synchronization plate 62 together with the extended end of the electric telescopic rod 61.

[0025] In practice, the sliding shaft 63 is splinedly connected to the first mounting frame 51, and the sliding shaft 63 is rotatably connected to the first clamping block 64. When the electric telescopic rod 61 controls the extension end to retract, it drives the sliding shaft 63 to move synchronously through the synchronous plate 62, so that the first clamping block 64 moves towards the second clamping block 78 to clamp and fix both ends of the axle-type automotive parts.

[0026] Furthermore, the reciprocating rotation mechanism 7 includes a vertical plate 71, a lead screw sleeve 72 fixedly connected to the rear end of the vertical plate 71, a lead screw 73 internally threadedly connected to the lead screw sleeve 72, a second clamping block 78 fixedly connected to one end of the lead screw 73, the second clamping block 78 being rotatably connected to the second mounting frame 52, a spherical universal joint 74 fixedly connected to the other end of the lead screw 73, a connecting rod 75 fixedly connected to the surface of the spherical universal joint 74, a rotating rod 76 hinged to the other end of the connecting rod 75, and the rotating rod 76 being fixedly connected to the output end of the first motor 77 fixedly connected to the front end of the vertical plate 71.

[0027] In specific implementation, the output end of the first motor 77 passes through the vertical plate 71 and is fixedly connected to the inner side of the top of the rotating rod 76. The outer side of the bottom end of the rotating rod 76 is hinged to one end of the connecting rod 75. The other end of the connecting rod 75 is connected to one end of the lead screw 73 through a ball joint 74. The ball joint 74 allows the connecting rod 75 and the lead screw 73 to rotate while facilitating the rotation of the lead screw 73. When the first motor 77 and the rotating rod 76 work together to control the reciprocating horizontal movement of the connecting rod 75 and the lead screw 73 at one end of the connecting rod 75, and because the second clamping block 78 is rotatably connected to the second mounting frame 52 and the second clamping block 78 is fixedly connected to the lead screw 73, when the lead screw 73 moves horizontally, it can drive the translation frame 5 to slide horizontally on the top of the moving block, realizing the radial horizontal movement grinding of the shaft-type automotive parts. A lead screw sleeve 72 is fixedly connected to one side. The lead screw sleeve 72 is rotatably connected to the vertical plate 71 and threadedly connected to the lead screw. In order to ensure that the lead screw 73 moves and rotates in the direction of the lead screw sleeve 72, a ball screw can be used in combination with the lead screw sleeve 72. The ball reduces the friction between the lead screw 73 and the lead screw sleeve 72, making it easier for the lead screw 73 to rotate axially under the influence of the lead screw sleeve 72 when it makes linear motion. Therefore, when the lead screw 73 rotates axially, it drives the second clamping block 78 to rotate. Since the first clamping block 64 and the second clamping block 78 clamp and fix the axle-type automotive parts, the rotation of the second clamping block 78 can drive the axle-type automotive parts to rotate axially synchronously, realizing the rotational grinding of the radial surface of the axle-type automotive parts.

[0028] Furthermore, the propulsion mechanism 8 includes a handwheel 81, with a threaded rod 82 coaxially fixedly connected to the rear end of the handwheel 81. The threaded rod 82 is rotatably mounted in the mounting groove at the top of the base 3, and a threaded sleeve 83 is threadedly connected to the surface of the threaded rod 82. The threaded rod 82 is fixedly connected to the bottom of the movable plate 4.

[0029] In practical implementation, the mounting slot is opened on the top of the base 3. Two mounting sleeves for mounting the threaded rod 82 can be installed at the bottom of the mounting slot. The threaded rod 82 can be rotated axially through the two mounting sleeves. The threaded sleeve 83 at the bottom of the moving plate 4 is threadedly connected to the threaded rod 82. The front end of the threaded rod 82 is coaxially fixedly connected to a handwheel 81. When it is necessary to adjust the distance between the part and the sanding belt according to the diameter of the axle-type automotive part, the handwheel 81 is turned, which drives the threaded rod 82 to rotate. The rotating threaded rod 82 drives the moving block to slide back and forth on the top of the base 3 through the threaded sleeve 83, thereby realizing the adjustment of the distance between the moving plate 4 and the sanding machine 2.

[0030] Furthermore, the front end of the movable plate 4 is provided with a receiving groove that cooperates with the belt sander 2.

[0031] In practical implementation, the receiving groove can conveniently prevent the sanding belt from rubbing against the side wall of the moving plate 4 when adjusting the position of the moving plate 4 and the sander 2, and provide space for the movement of the moving plate 4. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit it; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
