Description

Technical Field

[0001] The utility model relates to the technical field of rack fine grinding, in particular to a clamping device for rack fine grinding. Background Art

[0002] Racks are divided into two types: straight racks and helical racks. Helical racks are further divided into right-handed (rotational) and left-handed (rotational) according to the inclination direction of the teeth. The tooth line of a straight rack (i.e. a rack) is a straight line perpendicular to the direction of movement of the teeth, and the tooth line of a helical rack (i.e. a rack) forms an angle with the direction of movement of the teeth. At present, for the processing of racks, when the length of the rack is greater than 1mm and the tooth surface is a hardened tooth surface (50HRC-60HRC), the factory's ordinary milling machine cannot process it. In this case, the factory's production department can only outsource the processing, which will inevitably cause its production cost to increase significantly, the processing quality to vary, and even its delivery cycle to be difficult to guarantee.

[0003] In the patent document with the publication number CN204430471U, a clamping device for fine grinding of racks is disclosed. The device adjusts the hanging wheel of the thread grinder according to the pitch of the rack to be processed, adjusts the angle of the grinding wheel head frame to zero degrees, trims the grinding wheel according to the tooth angle of the rack to be processed, and then fixes the base of the device on the workbench of the thread grinder through the open mounting groove. The rack to be processed is pressed on the clamp body with a clamping bolt, and the tooth shape of the grinding wheel is aligned with the tooth shape of the rack to be processed. The driving handle is turned upward, and the driving handle can drive the clamp body to compress the reset spring downward through the driving rack. After releasing the reset spring, the reset spring can drive the clamp body to reset upward, and the processing of one tooth width of the rack to be processed can be completed in this reciprocating manner. After processing each tooth of the rack to be processed, the grinding wheel is withdrawn, and the workbench of the thread grinder moves an appropriate distance to process the next tooth.

[0004] However, after the rack is clamped and fixed, the device cannot allow the other side to be processed. When processing is required, the rack needs to be disassembled and reinstalled, which affects work efficiency. At the same time, the device cannot promptly remove the waste chips generated by the rack surface finishing, resulting in too much waste chips adhering to the surface, thereby affecting the quality of fine grinding.

[0005] Therefore, we propose a clamping device for rack fine grinding to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a clamping device for fine grinding of a rack, such as Figure 1 As shown, the workbench 1 includes a workbench 1, and legs 2 are respectively installed at the four corners of the bottom of the workbench 1. A drainage groove 3 is opened inside the workbench 1, and a water guide plate 5 is installed at the bottom of the drainage groove 3. A chip collection housing 6 is fixedly connected to the bottom of the water guide plate 5. Figure 2 As shown, chip discharge ports 4 are provided on both sides of the bottom of the chip collection housing 6, so that waste chips can be discharged through the chip discharge ports 4. Figure 3 As shown, a screw rod 19 is installed inside the chip collection shell 6, a sliding rod 20 is installed inside the chip collection shell 6, a rotating arm 18 is installed on one side of the screw rod 19, and the outer surface of the screw rod 19 is located inside the chip collection shell 6 and a cleaning plate 21 is installed. By shaking the rotating arm 18, the rotating arm 18 drives the screw rod 19 to rotate, thereby engaging with the cleaning plate 21. The cleaning plate 21 adopts a lightweight design to ensure that when the screw rod 19 rotates, the movement of the cleaning plate 21 can be easily seen; the cleaning plate 21 is repeatedly moved inside the chip collection shell 6, so that the waste chips inside the chip collection shell 6 are discharged from the chip discharge ports 4 on both sides, as shown in FIG. Figure 2As shown, a water tank 14 is installed at the bottom of the workbench 1, a transport pipe 16 is installed on one side of the water tank 14, a transport pump 15 is installed on the outer surface of the transport pipe 16, a connecting bracket 17 is installed on the top of the workbench 1, and a movable block 13 is movably connected to the outer surface of the connecting bracket 17, and the movable block 13 is fixedly connected to the transport pipe 16. The water inside the water tank 14 is transported through the transport pipe 16 by the transport pump 15, so as to flush the surface of the rack. At the same time, by moving the movable block 13, the movable pipe 16 can be driven to move, so as to adjust the position of the spray.

[0022] like Figure 1 As shown, a movable groove 7 is opened inside the workbench 1, and a hydraulic rod 8 is installed inside the movable groove 7. The output end of the hydraulic rod 8 is connected to a connecting rod 9, and a motor 10 is installed on one side of the top of the connecting rod 9. The output shaft of the motor 10 passes through the connecting rod 9 and is connected to a hydraulic rod 2 11. A clamping plate 12 is installed at the output end of the hydraulic rod 2 11. By placing the rack inside the clamping plate 12 and clamping it with the clamping plate 12, the entire rack can be driven to move by the hydraulic rod 8, thereby facilitating rapid positioning of the rack.

[0023] The bottom of the chip discharge port 4 may be connected to a cleaning box so that the waste chips can be collected uniformly, thereby preventing the waste chips from being discharged randomly and causing environmental pollution.

[0024] The transport pipe 16 is a retractable plastic hose, so that by moving the moving block 13, the transport pipe 16 can be retracted and expanded accordingly, thereby continuously supplying water.

[0025] The chip collecting housing 6 has an interior provided with a mounting groove for mounting a screw rod 19 and a slide rod 20 .

[0026] The rack to be processed is placed between the two clamping plates 12, and the hydraulic rod 11 is started to push the clamping plates 12 to start moving inward at the same time, so that the rack is clamped and fixed by the clamping plates 12. The hydraulic rod 18 is started to drive the connecting rod 9 to move quickly, so that the rack is quickly positioned. When the rack is ground (grinding is mainly done by the staff using a handheld grinding tool to trim the rack, or by adapting the entire clamping device to a grinder under the existing technology), the transport pump 15 is started to be driven by the transport pump 15. The delivery pump 15 transports the water inside the water tank 14 through the transport pipe 16 to flush the surface of the rack, so that the waste chips on the surface of the rack are gathered inside the chip collecting shell 6 through the water guide plate 5, and the waste chips are uniformly collected and discharged by connecting the waste chip box at the bottom of the chip discharge port 4. The rotating arm 18 is further rotated to drive the screw rod 19 to move, so that the cleaning plate 21 is further repeatedly moved inside the chip collecting shell 6, thereby pushing the debris inside the chip collecting shell 6 to the chip discharge ports 4 on both sides, so as to keep the chip collecting shell 6 from accumulating.
