Description

Technical Field

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

[0002] Automotive parts are various components, assemblies, and auxiliary products that make up a car, covering core systems such as engines, chassis, bodies, and electronic equipment, as well as parts for repair and replacement.

[0003] Under current conditions, a broaching grinder with convenient positioning, as disclosed in CN222095534U, is commonly used. This grinder includes a base and two support plates, and also includes an adjustment structure installed between the two support plates. This facilitates adjustment of the cutting position and provides positioning during the cutting process, making the cutting of materials more stable and improving cutting efficiency. However, this device lacks a workpiece fixing mechanism. Without any component to limit and fix the workpiece position during processing, displacement is likely to occur, leading to deviations in processing dimensions. Furthermore, the cutting area and the generated debris are completely exposed, allowing the debris to fly freely and easily cause injury to the operator's eyes and skin. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the lack of a stable workpiece clamping mechanism in existing broach grinding machines, which leads to deviations in machining dimensions and the easy occurrence of machining debris splashing and causing personal injury. Therefore, this invention proposes a broach grinding machine for machining automotive parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A broaching grinder for processing automotive parts includes a worktable and a tool assembly movably mounted on the worktable for workpiece processing. The worktable is provided with a graded adjustable clamping mechanism for clamping the workpiece, and the clamping mechanism includes a clamping plate movably mounted on the worktable for clamping the workpiece. The worktable is provided with a protective mechanism for intercepting workpiece debris, and the protective mechanism includes a fixed plate fixedly mounted on the worktable, and a protective cover for intercepting debris is mounted on the fixed plate by a pin.

[0007] Preferably, the clamping mechanism further includes a rotating rod rotatably mounted on the worktable, and a gear and a fixed wheel are keyed to the rotating rod. Two slide rods are fixedly mounted on the worktable, and rack one and rack two are slidably sleeved on the two slide rods respectively, which mesh with the gear and perform primary adjustment of the clamping plate.

[0008] The rack one and rack two are respectively fixedly installed with transmission blocks extending to the position above the worktable, and the transmission blocks are fixedly installed with mounting blocks. The mounting blocks are slidably fitted with guide rods integrally connected to the clamping plate. The mounting blocks are threadedly connected with hand-tightening bolts for readjusting the clamping plate. The worktable is movably provided with a limiting block for fixing the rotating rod.

[0009] Preferably, a fixing block is fixedly installed on the workbench, and a moving rod for applying pressure to the limiting block is slidably sleeved inside the fixing block. The fixing wheel has circumferentially distributed limiting grooves that correspond to the limiting block.

[0010] Preferably, the slide bar is horizontally positioned on both sides of the rotating rod, and the cross-section of the slide bar has a cross-shaped structure.

[0011] Preferably, the protective mechanism further includes a safety block fixedly installed on the protective cover, a pressure sensor corresponding to the safety block is fixedly installed on the fixed plate, and a positioning block is fixedly installed on the protective cover.

[0012] Preferably, the safety block is vertically mounted on the protective cover, and a magnetic block with opposite poles attracting each other is provided between the worktable and the positioning block.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model achieves rapid initial positioning of the workpiece through the combination of servo motor drive and mechanical transmission, and then completes secondary fixation through manual fine adjustment. The clamping process is efficient and convenient. At the same time, the limiting block and fixed wheel limit cooperation and the pressure fixation of the hand-tightened bolt ensure the stability and firmness of the workpiece clamping. It can adapt to the clamping requirements of workpieces of different specifications, effectively ensure the positional stability of the workpiece in the subsequent processing, and help improve the processing quality.

[0015] 2. This utility model can quickly cover the working area of ​​the worktable by rotating the protective cover around the pin shaft. The protective cover can be quickly fixed by adsorption with the positioning block, which can effectively intercept processing debris. At the same time, the safety block and the pressure sensor work together to ensure that the tool assembly can work normally when the protective cover is in the designated position. Once the protective cover is opened during processing, the pressure sensor sends a signal to the controller to immediately control the tool assembly to stop working, which can effectively avoid accidental injury to the staff and help improve the safety and reliability of equipment operation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A broaching grinder for processing automotive parts includes a worktable 1 and a tool assembly movably mounted on the worktable 1 for workpiece processing. A controller is provided on the worktable 1. The tool assembly is slidably connected to the worktable 1 via a linear guide rail and can reciprocate along the length of the worktable 1 to meet the processing needs of different workstations.

[0024] The worktable 1 is equipped with a clamping mechanism that allows for graded adjustment and workpiece clamping. The clamping mechanism enables graded adjustment and fixation of the workpiece, combining rapid positioning with precise clamping. This helps improve the adaptability and clamping stability of the workpiece and ensures processing quality.

[0025] The clamping mechanism includes a clamping plate 15 that is movably mounted on the worktable 1 and used to clamp the workpiece. The inner side of the clamping plate 15 is fitted with a rubber anti-slip pad to avoid scratching the surface of the workpiece during clamping and to increase the friction of the clamping surface.

[0026] The workbench 1 is equipped with a protective mechanism to intercept workpiece debris. The protective mechanism effectively intercepts processing debris through the protective cover 18, which can quickly cover the work area, preventing the debris generated during processing from accidentally injuring the workers. At the same time, the safety block 20 and the pressure sensor 5 work together to achieve a safety interlock that prevents the tool assembly from starting when the protective cover 18 is not fully closed, which helps to improve operational safety.

[0027] The protective mechanism includes a fixed plate 17 fixedly installed on the workbench 1, and a protective cover 18 for intercepting debris is installed on the fixed plate 17 by a pin. The protective cover 18 is made of transparent tempered glass, which makes it easy for operators to observe the processing status and has sufficient impact resistance to effectively block metal debris that splashes during processing.

[0028] The clamping mechanism also includes a rotating rod 2 rotatably mounted on the worktable 1. A servo motor for driving the rotating rod 2 to rotate is fixedly mounted on the worktable 1. A gear 3 and a fixed wheel 4 are keyed to the rotating rod 2. Two slide rods 6 are fixedly mounted on the worktable 1. A rack 7 and a rack 8 are slidably mounted on the two slide rods 6, which mesh with the gear 3 and perform primary adjustment of the clamping plate 15. The rack 7 and rack 8 are located on both sides of the gear 3, forming a symmetrical meshing structure with the gear 3, ensuring that when the gear 3 rotates, it can drive the rack 7 and rack 8 to move synchronously in opposite directions or towards each other.

[0029] A transmission block 12 extending to the top of the worktable 1 is fixedly installed on rack 7 and rack 8 respectively, and an mounting block 13 is fixedly installed on the transmission block 12. The mounting block 13 and the transmission block 12 are detachably connected by bolts, which facilitates subsequent maintenance and replacement.

[0030] The mounting block 13 is slidably fitted with a guide rod 14 that is integrally connected to the clamping plate 15. The mounting block 13 is threadedly connected with a hand-tightening bolt 16 for readjusting the clamping plate 15. The end of the hand-tightening bolt 16 is rotatably connected to the clamping plate 15 through a bearing to prevent the clamping plate 15 from rotating synchronously when the hand-tightening bolt 16 rotates.

[0031] A limiting block 11 for fixing the rotating rod 2 is movably installed on the workbench 1. The limiting block 11 can move in a direction perpendicular to the axis of the rotating rod 2 to achieve limiting or separation from the fixed wheel 4.

[0032] A fixed block 9 is fixedly installed on the workbench 1, and a movable rod 10 for applying pressure to the limiting block 11 is slidably sleeved inside the fixed block 9. The movable rod 10 consists of a limiting rod, a spring, and a movable block. The spring is welded between the movable block and the fixed block 9 and is in a compressed state to ensure that a continuous pushing force is applied to the limiting block 11.

[0033] The fixed wheel 4 has circumferentially distributed limiting grooves that correspond to the limiting block 11. The number of limiting grooves is adapted to the gear position of the gear 3 driving the rack to move, so as to ensure that the rotating rod 2 can be accurately positioned and fixed after the initial adjustment.

[0034] The slide rod 6 is horizontally positioned on both sides of the rotating rod 2. The cross-section of the slide rod 6 has a cross-shaped structure. The rack 7 and rack 8 are provided with cross-shaped grooves that are compatible with the slide rod 6. Through the cooperation of the cross-shaped structure, the rack 7 and rack 8 can be effectively prevented from deflecting during the sliding process, thus ensuring the accuracy of the movement direction.

[0035] The protective mechanism also includes a safety block 20 fixedly installed on the protective cover 18. A pressure sensor 5 corresponding to the safety block 20 is fixedly installed on the fixed plate 17. The pressure sensor 5 is fixed to the corresponding position of the fixed plate 17 by a bracket to ensure that the safety block 20 can accurately abut against the pressure sensor 5 when the protective cover 18 is closed. A positioning block 19 is fixedly installed on the protective cover 18.

[0036] The safety block 20 is vertically mounted on the protective cover 18, and the safety block 20 is located on the side of the protective cover 18 closer to the fixed plate 17, to prevent accidental contact with the pressure sensor 5 from causing it to send an incorrect signal to the controller, thereby further improving the safety of the equipment.

[0037] A magnetic block with opposite poles is provided between the worktable 1 and the positioning block 19. The magnetic block is embedded in the corresponding position of the worktable 1 and the positioning block 19. The magnetic block can quickly achieve the initial fixation of the protective cover 18 through the adsorption force of the magnetic block, which helps to improve the convenience of operation.

[0038] It should be noted that the specific models and specifications of the controller, pressure sensor 5, and servo motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0039] The functional principle of this utility model can be explained through the following operation methods:

[0040] Place the workpiece to be processed on the worktable 1, pull the moving rod 10, the moving rod 10 drives the limit block 11 to disconnect from the fixed wheel 4, the controller controls the servo motor to start, and then adjust the hand-tightening bolt 16 to the initial state;

[0041] The output of the servo motor drives the rotating rod 2 to rotate, and the rotating rod 2 drives the key-connected gear 3 to rotate. The gear 3 drives the two transmission blocks 12 to move towards each other through the meshing rack 7 and rack 8. The transmission blocks 12 drive the mounting block 13 to move synchronously. The mounting block 13 drives the clamping plate 15 to move to fit with the workpiece through the guide rod 14, completing the initial positioning of the workpiece. Then the moving rod 10 is released, and the moving rod 10 applies pressure to the limiting block 11, so that the limiting block 11 extends into the limiting groove of the fixed wheel 4 to fix the rotating rod 2.

[0042] Rotate the hand-tightening bolt 16, which drives the clamping plate 15 to move along the guide rod 14 and apply pressure to the workpiece, thereby achieving precise fixation of the workpiece. Then rotate the protective cover 18 around the pin on the fixing plate 17, so that the protective cover 18 covers the working area of ​​the worktable 1. The positioning block 19 is attracted to the worktable 1 by the magnetic blocks with opposite poles, thus completing the fixation of the protective cover 18.

[0043] During the rotation of the protective cover 18, the safety block 20 is rotated synchronously. When the protective cover 18 completely covers the working area, the safety block 20 abuts against the pressure sensor 5. The pressure sensor 5 sends an electrical signal to the controller, which controls the tool assembly to start and process the workpiece. During the processing, the protective cover 18 intercepts workpiece debris.

[0044] If the protective cover 18 is accidentally opened during processing, the protective cover 18 will cause the safety block 20 to disengage from the pressure sensor 5. The pressure sensor 5 will then send an electrical signal to the controller, which will stop the tool assembly from working, thus preventing workers from being injured by machinery.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
