Description

Technical Field

[0001] The utility model belongs to the technical field of grinder tooling, and in particular relates to a grinder tooling. Background Art

[0002] A grinder is a type of machine tool that uses abrasive tools to grind the surface of a workpiece. Grinding is one of the main methods for precision machining of machine parts. The principle of a grinder is to grind the surface of a workpiece by means of relative friction between a high-speed rotating grinding wheel and the workpiece surface. Since the rotation speed of the grinding wheel is very high, the grinder mainly relies on the relative friction between the grinding wheel and the workpiece to achieve grinding, which places high requirements on the fixed stability of the workpiece.

[0003] At present, most grinding machines mainly use strong magnetic adsorption to assemble and fix the workpiece during use. When this method is used to adsorb and fix the workpiece, the fixation state of the workpiece is closely related to the contact area between the workpiece and the worktable. For workpieces of the same quality, when the contact area between the workpiece and the worktable is large, the fixation state of the workpiece is relatively stable; when the contact area between the workpiece and the worktable is small, the fixation state of the workpiece is poor.

[0004] When grinding a workpiece with poor surface flatness, a corresponding fixed tool is needed to clamp and fix the workpiece. In the prior art, the tooling for grinding machines is large in size and has a small scope of application. At the same time, most of them cannot be magnetically fixed with the workbench, which makes the application of the tooling for grinding machines very limited and the actual application effect is poor.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a tooling for a grinding machine.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0007] The utility model aims to provide a tool for a grinder, which can improve the application range and practical application effect of the tool for a grinder.

[0008] In order to achieve the above-mentioned purpose, a specific embodiment of the utility model provides a tooling for a grinding machine, comprising: a workbench, a side-mounted clamping assembly, and an unfolded fixing assembly.

[0009] The side-mounted clamping assembly is fixedly installed above the workbench, and the side-mounted clamping assembly includes an assembly slide rail, which is fixedly connected to the side wall of the workbench, and a pair of fixed sliders are slidably installed on the side of the assembly slide rail away from the workbench, a threaded rod is threadedly connected between the pair of fixed sliders, and a clamping plate is slidably installed above the pair of fixed sliders.

[0010] The expandable fixing assembly is fixedly assembled above the workbench, and the expandable fixing assembly includes a pair of clamping fixing blocks, which are arranged on one side of a pair of clamping plates close to each other, and a pair of movable fixing blocks are hinged on one side of the pair of clamping fixing blocks close to each other.

[0011] In one or more embodiments of the utility model, both ends of the assembly slide rail are fixedly connected to a shaft fixing frame, the threaded rod passes through the shaft fixing frame, and the threaded rod is rotatably connected to the shaft fixing frame.

[0012] In one or more embodiments of the utility model, the two sides of the threaded rod are provided with external threads in opposite directions, and the pair of fixed sliders are provided with internal threads in the same direction. Through the cooperation between the internal and external threads, the pair of fixed sliders can move in opposite directions with the rotation of the threaded rod, thereby facilitating the driving of the pair of clamping plates to move. The end of the threaded rod located outside the rotating shaft fixing frame is fixedly connected to a rotating handle.

[0013] In one or more embodiments of the utility model, a pair of fixed sliders are rotatably connected with lifting threaded rods on their upper parts, the lifting threaded rods penetrate the clamping plate, and the lifting threaded rods are threadedly connected to the clamping plate. The lifting threaded rods play the role of thread locking and limiting and lifting and lowering guide for the clamping plate.

[0014] In one or more embodiments of the utility model, the outer side of the lifting threaded rod is rotatably mounted with a guide limit frame, and the guide limit frame is fixedly mounted above the fixed slider. The guide limit frame plays a role in assembling and fixing the lifting threaded rod. At the same time, the guide limit frame plays a role in lifting and limiting the clamping plate, thereby reducing the rotation of the clamping plate with the rotation of the lifting threaded rod under the action of the thread. The lifting threaded rod is fixedly connected to a lifting end head at one end outside the guide limit frame. The lifting threaded rod is controlled in rotation by controlling the rotation of the lifting end head, thereby facilitating the control of the lifting and lowering state of the clamping plate.

[0015] In one or more embodiments of the utility model, a pair of the clamping and fixing blocks are fixedly connected to a mounting plate on one side away from the movable fixing block, and the mounting plate is fixedly mounted above the clamping plate.

The movable fixing block is received by the receiving grooves, thereby ensuring the flatness of the clamping surface of the movable fixing block. The bottom of the pair of receiving grooves is cut with a sliding limit groove. The sliding limit groove plays the role of assembling and sliding limit for the supporting slider.

[0017] In one or more embodiments of the utility model, a support slider is slidably mounted in the sliding limit groove, and the support slider plays a role of supporting limit and moving control on the connecting rod. A sliding screw is rotatably connected in the clamping and fixing block, and the sliding screw runs through the clamping and fixing block and the support slider, and the sliding screw is threadedly connected to the support slider.

[0018] In one or more embodiments of the utility model, the two ends of the sliding screw are provided with external threads in opposite directions, and the pair of supporting sliders are provided with internal threads in the same direction. This facilitates the pair of supporting sliders to move in opposite directions as the sliding screw rotates under the action of the internal and external threads. The end of the sliding screw located outside the clamping fixed block is fixedly connected to an unfolding rotating end. The sliding screw is driven to rotate by controlling the rotation of the unfolding rotating end.

[0019] In one or more embodiments of the utility model, a connecting rod is hinged between the support slider and the movable fixed block. The connecting rod serves to connect the support slider and the movable fixed block, and the expansion angle of the movable fixed block is adjusted by controlling the movement of the connecting rod, so that the movable fixed block can be adaptively adjusted according to the actual situation of the workpiece.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, a tool for a grinding machine in one embodiment of the utility model comprises: a workbench 1, a side-mounted clamping assembly 2, and an unfoldable fixing assembly 3.

[0032] like Figure 6 As shown, the side-mounted clamping assembly 2 is fixedly mounted above the workbench 1, and the side-mounted clamping assembly 2 includes an assembly slide rail 201, and the assembly slide rail 201 is fixedly connected to the side wall of the workbench 1. The assembly slide rail 201 plays the role of assembly limit and sliding guide for the fixed slider 202.

[0033] like Figures 2 to 3 As shown, a pair of fixed sliders 202 are slidably mounted on one side of the assembly rail 201 away from the workbench 1. The fixed sliders 202 play the role of assembly limit for the clamping plate 204 and the lifting threaded rod 207. The movement of the clamping plate 204 is controlled by sliding the fixed sliders 202.

[0034] like Figures 2 to 3 As shown, a threaded rod 203 is threadedly connected between a pair of fixed sliders 202. The threaded rod 203 plays the role of supporting, limiting and moving control for the fixed sliders 202.

[0035] like Figures 2 to 3 As shown, both ends of the assembly slide rail 201 are fixedly connected with a shaft fixing frame 205, and the threaded rod 203 is arranged through the shaft fixing frame 205, and the threaded rod 203 is rotatably connected to the shaft fixing frame 205. The shaft fixing frame 205 plays the role of assembly limit for the threaded rod 203, ensuring the transmission stability of the threaded rod 203.

[0036] It is worth noting that the two sides of the threaded rod 203 are bored with external threads in opposite directions, and the pair of fixed sliders 202 are bored with internal threads in the same direction. Through the cooperation of the internal and external threads, the pair of fixed sliders 202 can move in opposite directions with the rotation of the threaded rod 203, thereby facilitating the movement of the pair of clamping plates 204.

[0037] like Figures 2 to 3 As shown, one end of the threaded rod 203 outside the rotating shaft fixing frame 205 is fixedly connected with a rotating handle 206. The threaded rod 203 is driven to rotate by controlling the rotating handle 206 to rotate.

[0038] like Figures 2 to 3 As shown, a clamping plate 204 is slidably mounted on the top of a pair of fixed sliders 202. The clamping plate 204 plays a role in assembling and fixing the expandable fixing assembly 3.

[0039] like Figures 2 to 3As shown, a pair of fixed sliders 202 are rotatably connected with lifting threaded rods 207 on their upper sides, the lifting threaded rods 207 are arranged through the clamping plate 204, and the lifting threaded rods 207 are threadedly connected with the clamping plate 204. The lifting threaded rods 207 play the role of thread locking and limiting and lifting and lowering guide for the clamping plate 204.

[0040] like Figures 2 to 3 As shown, the outer side of the lifting threaded rod 207 is rotatably equipped with a guide limit frame 208, and the guide limit frame 208 is fixedly assembled above the fixed slider 202. The guide limit frame 208 plays a role in assembling and fixing the lifting threaded rod 207. At the same time, the guide limit frame 208 plays a role in lifting and limiting the clamping plate 204, reducing the rotation of the clamping plate 204 with the rotation of the lifting threaded rod 207 under the action of the thread.

[0041] like Figures 2 to 3 As shown, one end of the lifting threaded rod 207 outside the guide limit frame 208 is fixedly connected with a lifting end 209. By controlling the rotation of the lifting end 209, the lifting threaded rod 207 is rotationally controlled, so as to facilitate the control of the lifting state of the clamping plate 204.

[0042] like Figures 2 to 5 As shown, the expandable fixing assembly 3 is fixedly assembled above the workbench 1, and the expandable fixing assembly 3 includes a pair of clamping and fixing blocks 301, and the pair of clamping and fixing blocks 301 are arranged on the side close to the pair of clamping plates 204. The clamping and fixing blocks 301 play the role of assembly limit and storage for the movable fixing blocks 302. At the same time, the workpiece can be clamped and fixed by the mutual cooperation of the pair of clamping and fixing blocks 301.

[0043] like Figures 2 to 5 As shown, a pair of clamping and fixing blocks 301 are hingedly connected to a pair of movable fixing blocks 302 on one side thereof, so as to facilitate clamping and fixing workpieces with poor outer surface flatness through the cooperation between the movable fixing blocks 302 and the clamping and fixing blocks 301.

[0044] like Figures 2 to 5 As shown, a pair of clamping and fixing blocks 301 are fixedly connected to a mounting plate 303 on one side away from the movable fixing block 302, and the mounting plate 303 is fixedly mounted above the clamping plate 204. The clamping and fixing blocks 301 are assembled and fixed by assembling and fixing the mounting plate 303.

[0045] Among them, a pair of receiving grooves are cut on the side of the pair of clamping and fixing blocks 301 away from the clamping plate 204, and the pair of receiving grooves are arranged in cooperation with the movable fixing block 302. The movable fixing block 302 is received by the receiving grooves, thereby ensuring the flatness of the clamping surface of the movable fixing block 302.

[0046] Specifically, a pair of the receiving grooves are both provided with sliding limit grooves at the bottom thereof, and the sliding limit grooves play the role of assembling and sliding limit for the supporting slider 304 .

[0047] like Figures 4 to 5 As shown, a support slider 304 is slidably mounted in the sliding limit groove, and the support slider 304 plays a role in supporting, limiting and moving control of the connecting rod 307.

[0048] like Figures 4 to 5 As shown, a sliding screw 305 is rotatably connected in the clamping and fixing block 301, and the sliding screw 305 is arranged through the clamping and fixing block 301 and the supporting slider 304, and the sliding screw 305 is threadedly connected to the supporting slider 304. The sliding screw 305 plays the role of assembly limit and sliding control for the supporting slider 304.

[0049] It is worth noting that the two ends of the sliding screw 305 are bored with external threads in opposite directions, and the pair of supporting sliders 304 are bored with internal threads in the same direction, so that the pair of supporting sliders 304 can move in opposite directions as the sliding screw 305 rotates under the action of the internal and external threads.

[0050] like Figures 4 to 5 As shown, one end of the sliding screw 305 located outside the clamping fixed block 301 is fixedly connected to the unfolding rotating end 306. The sliding screw 305 is driven to rotate by controlling the unfolding rotating end 306 to rotate.

[0051] like Figures 4 to 5 As shown, a connecting rod 307 is hinged between the support slider 304 and the movable fixed block 302. The connecting rod 307 serves to connect the support slider 304 and the movable fixed block 302. By controlling the movement of the connecting rod 307, the expansion angle of the movable fixed block 302 is adjusted, so that the movable fixed block 302 can be adaptively adjusted according to the actual situation of the workpiece.

[0052] When in use, the workpiece to be processed is placed on the workbench 1, and the threaded rod 203 is driven to rotate by controlling the rotation of the rotating handle 206. A pair of fixed sliders 202 drive a pair of clamping plates 204 to move in opposite directions under the action of internal and external threads.

[0053] As the pair of clamping plates 204 move, the workpiece to be processed can be initially clamped by the pair of clamping and fixing blocks 301. At the same time, the clamping plates 204 can be adjusted in level by controlling the rotation of the lifting threaded rod 207, and the height of the clamping and fixing blocks 301 can be adjusted according to the actual situation of the workpiece to be processed, thereby improving the clamping and fixing effect of the clamping and fixing blocks 301 on the workpiece to be processed. Subsequently, the workpiece to be processed can be auxiliaryly fixed by magnetic adsorption of the workbench 1.

[0054] When the outer surface flatness of the workpiece to be processed is poor, the sliding screw 305 can be driven to rotate by controlling the rotation of the unfolding rotating end 306, and a pair of supporting sliders 304 move in opposite directions under the action of internal and external threads. The connecting rod 307 is moved by the movement of a pair of supporting sliders 304, so as to control the unfolding state of the movable fixed block 302. By adjusting the unfolding state of the movable fixed block 302, the clamping fixed block 301 can cooperate with the movable fixed block 302 to clamp and fix the workpiece to be processed.

[0055] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
