Description

Technical Field

[0001] This utility model specifically relates to the field of automotive mold polishing technology, and more specifically to a reciprocating grinding mechanism for polishing mold surfaces. Background Technology

[0002] After processing (such as cutting, electrical discharge machining), the surface of the mold will have microscopic uneven textures. In order to ensure the accuracy of the mold after closing, the mold surface needs to be polished to achieve the required processing precision. A smooth surface can reduce the friction between the mold and the molding material (such as metal, plastic, rubber), reduce material adhesion, and extend the service life of the mold. Polishing of the mold is generally achieved by mechanical friction between the abrasive (sandpaper, polishing paste, polishing wheel, etc.) and the mold surface.

[0003] However, in practice, it has been noted that the rotation and movement directions of the polishing wheel are key factors affecting the polishing effect, efficiency, and safety during mold polishing or metal surface treatment. During the reciprocating polishing of the mold surface, since the polishing cloth wheel always rotates in one direction, the rotation and movement directions of the polishing cloth wheel will be the same during one stroke. At this time, the polishing effect will be greatly reduced, thus affecting the polishing accuracy of the mold. Utility Model Content

[0004] The purpose of this invention is to provide a reciprocating polishing mechanism for polishing mold surfaces. By utilizing the cooperation between a steering mechanism and a trapezoidal steering plate, the screw-driven reciprocating steering mechanism is turned during movement, ensuring that the rotation direction of the polishing cloth wheel is always opposite to its movement direction during the reciprocating polishing process, thereby improving the polishing effect on the mold. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reciprocating polishing mechanism for polishing the surface of a mold includes a mold fixing worktable for fixing the mold, a polisher above the mold fixing worktable, and a reciprocating turning mechanism installed above the polisher.

[0007] The reciprocating steering mechanism includes a steering shaft fixedly connected to the polisher, and positioning clamps are provided on both sides of the steering shaft. A hollow shell is sleeved on the outside of the steering shaft and the positioning clamps, and an end fixing plate is fixedly connected to the top of the hollow shell.

[0008] The steering shaft includes a diamond-shaped center plate, with steering rollers movably connected to both ends of the diamond-shaped center plate. An extension fixing post is fixedly connected to the lower part of the diamond-shaped center plate, and a steering gear is fixedly connected to the outer side of the extension fixing post.

[0009] As a further technical solution of this utility model, the steering gear includes an eccentric bent plate, and an extension fixing column passes through one end of the eccentric bent plate, while the other end of the eccentric bent plate is integrally provided with a cylindrical protrusion.

[0010] The eccentric bent plate is symmetrically fixedly connected to a fastener mounting plate at one end near the extension fixing column, and the fastener mounting plate is bolted to the extension fixing column.

[0011] As a further technical solution of this utility model, the positioning clamp includes concave clamping seats that fit against both sides of the rhomboid center plate, and the two sides of the concave clamping seats are symmetrically provided with limiting grooves, and each limiting groove is slidably fitted with a positioning slide rail.

[0012] As a further technical solution of this utility model, a compression spring is fixedly connected to the side of the concave clamping seat away from the rhomboid center plate, and the other end of the compression spring is fixedly connected to the hollow shell.

[0013] The positioning slide rail is fixedly connected to the inner side of the hollow shell.

[0014] As a further technical solution of this utility model, the top of the end fixing plate is integrally provided with a sliding connecting seat, and the sliding connecting seat is provided with a threaded hole, and a threaded screw is threadedly fitted on the inner side of the threaded hole, and both ends of the threaded screw are movably connected to a support side plate.

[0015] A servo motor is fixedly connected to the side of the support plate on any one side, and one end of the servo motor is engaged with the end of the threaded screw.

[0016] As a further technical solution of this utility model, the two supporting side plates are symmetrically fixedly connected with limiting slide rods, and both sides of the sliding connecting seat are provided with light holes corresponding to the limiting slide rods, and the limiting slide rods pass through the inner side of the light holes.

[0017] As a further technical solution of this utility model, the two ends of the threaded screw are also provided with linear modules, and the linear modules are fixedly connected to the side of the support side plate away from the threaded screw. Moreover, the bottom of the support side plate is also integrally provided with a trapezoidal steering plate corresponding to the cylindrical protrusion.

[0018] As a further technical solution of this utility model, a base is fixedly connected to the bottom of the mold fixing workbench, and a protective cover is fixedly connected to the top of the base. The linear modules are fixedly connected to both sides of the protective cover, and the mold fixing workbench is located on the lower inner side of the protective cover.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model uses the threaded engagement between the threaded hole and the threaded screw to enable the reciprocating steering mechanism to drive the polisher to slide above the mold. The servo motor at the end enables the reciprocating steering mechanism to move back and forth. When the end of the steering mechanism contacts the trapezoidal steering plate, the steering mechanism drives the steering shaft connected to the polisher to rotate, ensuring that the movement direction of the polishing cloth wheel is always opposite to the rotation direction, thereby improving the polishing effect on the mold surface.

[0021] 2. In this utility model, the compression spring pushes the concave clamping seat toward the rhomboid center plate through its own elastic force. The concave clamping seat is fixed by the groove on its side that corresponds to the rhomboid center plate, so that it moves in one direction. During the turning process, the rhomboid center plate can push the concave clamping seats on both sides to move outward, compressing the compression spring on the other side of the concave clamping seat. When the rhomboid center plate passes the center of the concave clamping seat, the reaction force of the compression spring helps the rhomboid center plate to complete the turning.

[0022] 3. In this utility model, both sides of the concave clamping seat are provided with limiting slide grooves, and positioning slide rails are inserted and matched in the limiting slide grooves. When the concave clamping seat slides inside the hollow shell, the sliding cooperation between the limiting slide grooves and the positioning slide rails can limit the concave clamping seat, so that it can only slide laterally.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-9 This utility model embodiment provides a reciprocating polishing mechanism for polishing the surface of a mold, including a mold fixing worktable 3 for fixing the mold, a polisher 9 above the mold fixing worktable 3, and a reciprocating turning mechanism 8 installed above the polisher 9.

[0036] The reciprocating steering mechanism 8 includes a steering shaft 85 fixedly connected to the polisher 9. Both sides of the steering shaft 85 are provided with positioning clamps 86. A hollow shell 81 is sleeved on the outside of the steering shaft 85 and the positioning clamps 86. An end fixing plate 82 is fixedly connected to the top of the hollow shell 81.

[0037] The steering shaft 85 includes a rhomboid center plate 851, with steering rollers 852 movably connected to both ends of the rhomboid center plate 851. An extension fixing post 853 is fixedly connected to the lower part of the rhomboid center plate 851, and a steering gear 83 is fixedly connected to the outer side of the extension fixing post 853.

[0038] Furthermore, the steering gear 83 includes an eccentric bent plate 831, and an extension fixing post 853 passes through one end of the eccentric bent plate 831, while the other end of the eccentric bent plate 831 is integrally provided with a cylindrical protrusion 833.

[0039] The eccentric bent plate 831 is symmetrically fixedly connected to a fastener mounting plate 832 at one end near the extension fixing post 853, and the fastener mounting plate 832 is bolted to the extension fixing post 853.

[0040] Furthermore, the positioning clamp 86 includes concave clamping seats 861 that fit against both sides of the rhomboid center plate 851, and both sides of the concave clamping seats 861 are symmetrically provided with limiting grooves 864, and each limiting groove 864 is slidably fitted with a positioning slide rail 863.

[0041] More specifically, a compression spring 862 is fixedly connected to the side of the concave clamping seat 861 away from the rhomboid center plate 851, and the other end of the compression spring 862 is fixedly connected to the hollow shell 81.

[0042] The positioning slide rail 863 is fixedly connected to the inner side of the hollow shell 81.

[0043] By adopting the above technical solution, the compression spring 862 pushes the concave clamping seat 861 toward the rhomboid center plate 851 with its own elastic force. The grooves on the side of the concave clamping seat 861 that correspond to the rhomboid center plate 851 fix it, so that it moves in one direction. During the turning process, the rhomboid center plate 851 can push the concave clamping seats 861 on both sides to move outward, compressing the compression spring 862 on the other side of the concave clamping seat 861. When the rhomboid center plate 851 passes the center of the concave clamping seat 861, the reaction force of the compression spring 862 helps the rhomboid center plate 85 to complete the turning.

[0044] Furthermore, the top of the end fixing plate 82 is integrally provided with a sliding connecting seat 84, and the sliding connecting seat 84 is provided with a threaded hole 841, and the inner side of the threaded hole 841 is threaded with a threaded screw 6, and both ends of the threaded screw 6 are movably connected to a support side plate 5.

[0045] A servo motor is fixedly connected to the side of the support plate 5 on any one side, and one end of the servo motor is engaged with the end of the threaded screw 6.

[0046] By adopting the above technical solution, the reciprocating steering mechanism 8 drives the polisher 9 to slide above the mold through the threaded engagement between the threaded hole 841 and the threaded screw 6. The reciprocating steering mechanism 8 is moved back and forth by the servo motor set at the end. When the end of the steering device 83 contacts the trapezoidal steering plate 10, the steering device 83 drives the steering shaft 85 connected to the polisher 9 to rotate, ensuring that the movement direction of the polishing cloth wheel 93 is always opposite to the rotation direction, thereby improving the polishing effect on the mold surface.

[0047] More specifically, the two supporting side plates 5 are symmetrically fixedly connected with limiting slide rods 7, and both sides of the sliding connecting seat 84 are provided with light holes 842 corresponding to the limiting slide rods 7, and the limiting slide rods 7 pass through the inner side of the light holes 842.

[0048] Furthermore, the threaded screw 6 is provided with linear modules 4 at both ends, and the linear modules 4 are fixedly connected to the side of the support side plate 5 away from the threaded screw 6. Moreover, the bottom of the support side plate 5 is integrally provided with a trapezoidal steering plate 10 corresponding to the cylindrical protrusion 833.

[0049] Furthermore, a base 2 is fixedly connected to the bottom of the mold fixing workbench 3, and a protective cover 1 is fixedly connected to the top of the base 2. The linear module 4 is fixedly connected to both sides of the protective cover 1, and the mold fixing workbench 3 is located on the inner side of the protective cover 1.

[0050] By adopting the above technical solution, both sides of the concave clamping seat 861 are provided with limiting slide grooves 864, and positioning slide rails 863 are inserted and matched in the limiting slide grooves 864. When the concave clamping seat 861 slides inside the hollow shell 81, the sliding cooperation between the limiting slide grooves 864 and the positioning slide rails 863 can limit the concave clamping seat 861, so that it can only slide laterally.

[0051] Furthermore, the polisher 9 includes a connecting bracket 91 fixedly connected to the bottom of the extended fixed column 853. A rotary motor 92 and a polishing cloth wheel 93 are respectively provided on both sides of the connecting bracket 91. The rotary motor 92 is fixedly connected to the connecting bracket 91, and the end of the rotary motor 92 passes through the connecting bracket 91 and is in transmission cooperation with the polishing cloth wheel 93. The rotary motor 92 drives the polishing cloth wheel 93 to rotate at high speed.

[0052] More specifically, the trapezoidal turning plates 10 on both sides are staggered to ensure that when the eccentric bent plate 831 moves with the hollow shell 81, the cylindrical protrusion 833 at the end of the eccentric bent plate 831 can contact the inclined surface of the trapezoidal turning plate 10. As the hollow shell 81 moves, the inclined surface of the trapezoidal turning plate 10 can guide the cylindrical protrusion 833, so that the cylindrical protrusion 833 deflects around the extended fixed column 853 as the axis.

[0053] More specifically, the end of the eccentric bent plate 831 away from the extension fixing post 853 is inclined towards the side closer to the support side plate 5, ensuring that the cylindrical protrusion 833 at the end of the eccentric bent plate 831 first contacts the trapezoidal turning plate 10. When the trapezoidal turning plate 10 guides the cylindrical protrusion 833 to the side, the rhomboid center plate 851 has already passed the center position of the concave clamping seat 861 and deflected to one side. Through mutual cooperation, the concave clamping seat 861 is flipped.

[0054] The working principle of this utility model is as follows: In use, the car mold to be polished is first placed on the mold fixing worktable 3. Then, the cylinder at the bottom pushes the mold fixing worktable 3 upwards until the mold contacts the polishing cloth wheel 93 in the polisher 9. The rotary motor 92 drives the polishing cloth wheel 93 to rotate at high speed to polish the mold surface. Simultaneously, the servo motor at the end of the threaded screw 6 provides power. Through the threaded engagement between the threaded screw 6 and the sliding connecting seat 84, the reciprocating steering mechanism 8 drives the polisher 9 to move on the mold surface. When the polisher 9 moves to the limit position at either end, the trapezoidal steering plate 10 contacts the cylindrical protrusion 833 at the end of the eccentric bending plate 831. As the reciprocating steering mechanism 8 continues to move, the eccentric bending plate 831 will be affected by the trapezoidal steering plate... The obstruction of 10 causes the extension fixing post 853 to deflect, and at the same time, the extension fixing post 853 causes the rhomboid center plate 851 to rotate. The steering rollers 852 at both ends of the rhomboid center plate 851 push the concave clamping seat 861 to move outward, compressing the compression spring 862. When the rhomboid center plate 851 passes the center position of the concave clamping seat 861, the reaction force of the compression spring 862 will push the rhomboid center plate 851 to continue rotating until the steering is completed, causing the polisher 9 to flip. Then, the servo motor at the end of the threaded screw 6 rotates in the opposite direction, driving the polisher 9 to move back and forth. The reciprocating movement of the polisher 9 can ensure that the direction of movement is opposite to the rotation direction of the polishing cloth wheel 93, thereby improving the polishing effect. The structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.
