Description

Technical Field

[0001] This utility model relates to the field of dumbbell processing technology, specifically to a metal rod grinding device for dumbbell processing. Background Technology

[0002] Dumbbells are commonly used fitness equipment. During their production, the metal rods used for connecting the bars need to be polished. Existing polishing devices collect the debris from the cutting process into a collection chamber at the bottom of the device. However, when the metal rods are cooled by spraying coolant, the debris becomes coated with coolant, significantly increasing its stickiness and making it easy to stick to the inside of the collection chamber, making it difficult to clean out.

[0003] In the prior art, Chinese patent document CN219747300U was proposed to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: A metal connecting rod grinding device includes a worktable, a clamp is provided on the upper surface of the worktable, and a grinding mechanism is provided on the inner wall of the worktable. This utility model incorporates a filter cylinder, providing the internal force for tilting and sliding. Simultaneously, a heating plate is provided inside the stirring blades, allowing the heating plate to transfer heat to the debris through the stirring blades, drying the debris. This facilitates the discharge of debris through the stirring of the stirring blades and the tilting and rolling of the filter cylinder. This solves the problem in existing devices where, when the metal connecting rod is cooled by spraying coolant, the debris becomes heavily viscous due to the coolant, easily adhering to the inside of the collection chamber and making it difficult to remove.

[0004] However, the above solution uses a surface clamping method, which results in a large amount of the metal rod being blocked, affecting the area that can be polished. Utility Model Content

[0005] The purpose of this invention is to provide a metal rod grinding device for dumbbell processing, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A metal rod grinding device for dumbbell processing includes a grinding table, the grinding table including a table body, a waste hopper fixedly installed on the inner wall of the table body, and a support member provided on the top of the waste hopper;

[0008] The platform surface is provided with two sets of clamping members, left and right. Each set of clamping members includes a docking unit and a clamping unit, and the clamping unit is disposed on the surface of the docking unit.

[0009] The bottom of the waste hopper is equipped with a rotating component.

[0010] A further improvement of this utility model is that the support member includes a connecting plate, the end face of which is fixedly connected to the inner wall of the waste hopper, a self-locking screw is threadedly installed on the surface of the connecting plate, a supporting arc plate is provided at the top of the self-locking screw, and the self-locking screw is rotatably connected to the inner wall of the supporting arc plate through a bearing seat. By setting the support member, the metal rod can be placed on the supporting arc plate and moved upward by rotating the self-locking screw for positioning, which can be achieved by a single person. At the same time, the supporting arc plate and the self-locking screw can also support the metal rod during grinding to prevent the metal rod from falling due to pressure.

[0011] A further improvement of this utility model is that the docking unit includes a support base, the bottom surface of which is fixedly connected to the top surface of the platform, and a rotating disk is slidably mounted horizontally through the top of the support base. A short gear rod is fixedly mounted on the outer side of the rotating disk. By setting the rotating disk, a clamping unit can be installed, and the metal rod can be driven to rotate in cooperation with the short gear rod and the rotating component.

[0012] A further improvement of this utility model is that the clamping unit includes a connecting frame, the end face of the connecting frame is fixedly connected to the inner side of the rotating disk, a screw is threaded through one end of the connecting frame, and a clamping block is fixedly installed at one end of the screw. By setting the clamping component, the screw can drive the clamping movement to clamp both ends of the metal rod, thereby effectively reducing the contact area with the surface of the metal rod, so that the side surface of the metal rod can be polished. At the same time, a dust cover can be set to protect the screw.

[0013] A further improvement of this utility model is that the rotating component includes a dual-axis geared motor, the top surface of the dual-axis geared motor support is fixedly connected to the bottom surface of the waste hopper, a long gear rod is fixedly installed at the output end of the dual-axis geared motor, and a synchronous toothed belt is meshed at the end of the long gear rod. The model of the dual-axis geared motor is MBW15.

[0014] A further improvement of this utility model is that: dust covers are slidably fitted onto the surfaces of both the screw and the clamping block, and the other end of the dust cover is slidably fitted onto the surface of the connecting frame. By setting the dust cover, the screw can be protected and prevent debris from adhering and affecting its rotation and movement.

[0015] A further improvement of this utility model is that: a hexagonal rotating handle is fixedly installed on both the self-locking screw and the screw end, and the synchronous toothed belt passes through the platform and meshes with the short gear rod.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a metal rod grinding device for dumbbell processing. By setting a clamping component, the screw can drive the clamping movement to clamp both ends of the metal rod, thereby effectively reducing the contact area with the surface of the metal rod and realizing that the side surface of the metal rod can be ground. At the same time, a dust cover can be set to protect the screw.

[0018] 2. This utility model provides a metal rod grinding device for dumbbell processing. By setting a rotating component, a dual-axis reduction motor can be started to drive the long gear rod to rotate, thereby driving the short gear rod and the rotating disk to rotate under the series of synchronous toothed belts, which in turn can drive the clamping unit and the metal rod to rotate to expand the grinding range.

[0019] 3. This utility model provides a metal rod grinding device for dumbbell processing. By setting a support member, the metal rod can be placed on the support arc plate and moved upward by rotating the self-locking screw for positioning. It can be operated by a single person.

[0034] Example 3

[0035] like Figures 1-5As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the rotating component 4 includes a dual-axis reduction motor 41, the top surface of the support of the dual-axis reduction motor 41 is fixedly connected to the bottom surface of the waste hopper 102, a long gear rod 42 is fixedly installed at the output end of the dual-axis reduction motor 41, a synchronous toothed belt 43 is meshed at the end of the long gear rod 42, a hexagonal rotating handle is fixedly installed at the ends of the self-locking screw 22 and the screw 35, and the synchronous toothed belt 43 passes through the platform 101 and meshes with the short gear rod 33.
