Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a metal surface polishing device. Background Technology

[0002] The two ends of metal jewelry require frequent polishing to meet requirements. Due to the small size of metal jewelry, it is difficult to clamp and automate the polishing process. Utility Model Content

[0003] To solve the above problems, this technical solution provides a metal surface polishing device.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A metal surface polishing device, comprising

[0006] frame;

[0007] A transport rack is used to place workpieces and allow them to roll from one end to the other.

[0008] A positioning mechanism for positioning the workpiece on the transport frame at the polishing station;

[0009] Clamping mechanism, used to clamp the workpiece at the polishing station from the top and bottom;

[0010] A polishing mechanism for polishing the front and back of a workpiece held by the clamping mechanism;

[0011] A moving mechanism is used to drive the polishing mechanism to move closer to or further away from the polishing station;

[0012] When the polishing mechanism moves toward the polishing station, it is linked to the positioning mechanism, which gradually moves away from the polishing station to cancel the positioning of the workpiece; when the polishing mechanism moves away from the polishing station, it is linked to the positioning mechanism, which gradually moves toward the polishing station to position the workpiece.

[0013] As described above, a metal surface polishing device includes a clamping mechanism comprising clamping cylinders respectively disposed on the upper and lower sides of the transport frame, a clamping head disposed on the output end of the clamping cylinder, a clamping slider disposed on the clamping head, and a clamping slide rail cooperating with the clamping slider.

[0014] As described above, in a metal surface polishing device, the workpiece is provided with an annular groove, and the clamping head is provided with a semi-circular clamping groove. The two clamping cylinders drive the two clamping heads respectively so that the clamping groove is inserted into the annular groove.

[0015] As described above, in a metal surface polishing device, the moving mechanism includes a moving cylinder mounted on the frame, a moving platform connected to the output end of the moving cylinder, a moving slide rail mounted on the frame, and a moving slider disposed between the moving platform and the moving slide rail. The polishing mechanism and the positioning mechanism are mounted on the moving platform.

[0016] As described above, a metal surface polishing device includes polishing machines respectively arranged on the left and right sides of the transport frame and mounted on the moving platform. The transport frame is provided with left and right openings corresponding to the two polishing machines, and the left and right openings allow the front and rear of the workpiece to be exposed on the transport frame.

[0017] As described above, in a metal surface polishing device, the positioning mechanism includes a positioning rod, a transmission rod mounted on the moving platform and hinged to the lower end of the positioning rod, and a hinge seat on the transport frame that is hinged to the middle of the transmission rod. When the moving platform moves toward the transport frame, the transmission rod pushes the positioning rod so that the upper part of the positioning rod exits the transport frame.

[0018] In the metal surface polishing equipment described above, a space is left between the positioning mechanism and the polishing station for a workpiece to rest.

[0019] The beneficial effects of this application are:

[0020] This invention provides a metal surface polishing device. A workpiece is placed on a transport frame and rolls down under gravity until it is stopped by a positioning mechanism, bringing it to a polishing station. A clamping mechanism holds the workpiece, and then the polishing mechanism, driven by a moving mechanism, begins polishing. Simultaneously, the positioning mechanism releases its grip. After polishing, the clamping mechanism releases its grip, the polishing mechanism gradually moves away from the workpiece, and the workpiece begins to roll down. At the same time, the positioning mechanism begins to restrain the next workpiece. This achieves automated polishing. Attached Figure Description

[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0022] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0023] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] A metal surface polishing device, comprising

[0025] Rack 1;

[0026] Transport frame 2, which is used to place workpiece 7 and allow the workpiece to roll from one end to the other;

[0027] Positioning mechanism 3, which is used to position the workpiece of the transport frame 2 on the polishing station 8;

[0028] Clamping mechanism 4 is used to clamp the workpiece at the polishing station from the top and bottom.

[0029] Polishing mechanism 5 is used to polish the front and back of the workpiece held by clamping mechanism 4;

[0030] The moving mechanism 6 is used to drive the polishing mechanism 5 to move toward or away from the polishing station;

[0031] When the polishing mechanism 5 moves toward the polishing station, it is linked to the positioning mechanism 3, which gradually moves away from the polishing station to cancel the positioning of the workpiece; when the polishing mechanism 5 moves away from the polishing station, it is linked to the positioning mechanism 3, which gradually moves toward the polishing station to position the workpiece.

[0032] This utility model provides a metal surface polishing device. The workpiece is placed on a transport frame and rolls down under the action of gravity until it is restricted by a positioning mechanism, so that a workpiece stops at the polishing station. The clamping mechanism clamps the workpiece, and then the polishing mechanism starts polishing the workpiece under the drive of the moving mechanism. At the same time, the positioning mechanism releases the restriction. After polishing is completed, the clamping mechanism releases the clamp, the polishing mechanism gradually moves away from the workpiece, and the workpiece begins to roll down. At the same time, the positioning mechanism begins to restrict the next workpiece.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the clamping mechanism 4 includes clamping cylinders 41 respectively disposed on the upper and lower sides of the transport frame 2, a clamping head 42 disposed on the output end of the clamping cylinder 41, a clamping slider 43 disposed on the clamping head 42, and a clamping slide rail 44 cooperating with the clamping slider 43. The clamping head is inserted into the transport frame for clamping.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the workpiece is provided with an annular groove 71, and the clamping head 42 is provided with a semi-circular clamping groove 45. The two clamping cylinders 41 respectively drive the two clamping heads 42 so that the clamping groove 45 is inserted into the annular groove 71. By utilizing the shape of the workpiece itself, the workpiece can be limited while being clamped.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the moving mechanism 6 includes a moving cylinder 61 mounted on the frame 1, a moving platform 62 connected to the output end of the moving cylinder 61, a moving slide rail 63 mounted on the frame 1, and a moving slider 64 disposed between the moving platform 62 and the moving slide rail 63. The polishing mechanism 5 and the positioning mechanism 3 are mounted on the moving platform 62. The positioning mechanism does not require an additional drive source, which is beneficial for simplifying the structure.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the polishing mechanism 5 includes polishing machines 51 respectively arranged on the left and right sides of the transport frame 2 and mounted on the moving platform 62. The transport frame 2 is provided with left and right openings 21 corresponding to the two polishing machines 51, and the left and right openings 21 allow the front and back of the workpiece to be exposed on the transport frame 2.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the positioning mechanism 3 includes a positioning rod 31, a transmission rod 32 mounted on the moving platform 62 and hinged to the lower end of the positioning rod 31, and a hinge seat 22 hinged to the middle of the transmission rod 32 on the transport frame 2. When the moving platform 62 moves towards the transport frame 2, the transmission rod 32 pushes the positioning rod 31, causing the upper part of the positioning rod 31 to exit the transport frame 2. When the moving platform drives the polishing machine to exit, the positioning rod gradually enters the transport frame, allowing the polished workpiece to have a time roller and pass over the positioning rod. Subsequently, the positioning rod enters the transport frame to position the next workpiece.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, a space 9 is left between the positioning mechanism 3 and the polishing station for a workpiece to rest. This helps prevent the polishing machine from contacting the positioning rod, provides adjustment space to accommodate different workpiece sizes, and allows the polished workpiece to rest in the space for observation of the polishing effect.

[0039] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
