Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a bar stock rough grinding device. Background Technology

[0002] In the field of machining, especially in the rough grinding of bar stock, ensuring the stability of the workpiece throughout the grinding process is one of the key factors in obtaining high-quality finished products.

[0003] Most existing bar grinding equipment relies on simple clamps to hold the workpiece in place. While this method meets basic holding requirements, it is prone to slight displacement of the workpiece due to vibrations or impacts during high-speed grinding, affecting the surface quality and dimensional accuracy of the final product. This means that even if the workpiece is initially secured, it may still wobble due to external forces, especially when processing bars with large length-to-diameter ratios or irregularly shaped workpieces. Utility Model Content

The two protrusions are respectively located in the first sliding groove and the second sliding groove. One end of the sliding frame is rotatably connected to the translation block. The telescopic rod of the electric push rod is connected to the translation block. The electric push rod drives the sliding frame to move through the translation block, and the bar is further fixed through the contact between the sliding frame and the bar.

[0008] As a preferred technical solution of this utility model, the bar rough grinding device also includes a motor, the output shaft of which is connected to the clamping assembly and mounted on the base two, and the motor drives the clamping assembly to rotate.

[0009] As a preferred technical solution of this utility model, the bar rough grinding device also includes a cooling box, an inlet pipe and an outlet pipe. The cooling box is installed on the grinding wheel spindle, and the inlet pipe and outlet pipe are respectively connected to the cooling box. The grinding wheel spindle is cooled by circulating coolant.

[0010] As a preferred technical solution of this utility model, the bar rough grinding device also includes an anti-slip pad, which is disposed on the contact surface between the fixed block and the bar to increase the friction between the fixed block and the bar.

[0011] The beneficial effects are as follows: 1.

[0020] A rough grinding apparatus for bar stock, see [link / reference] Figures 1-5 As shown, the system includes a base 1, a base 2, an electric slide 2, an electric slide 3, a grinding wheel spindle 4, a grinding wheel 5, a synchronous follower bracket 6, a clamping assembly 8, a motor 9, a fixing block 11, an electric push rod 12, a sliding frame 13, a translation block 120, a protrusion 150, a water inlet pipe 16, a water outlet pipe 17, a cooling box 18, and an anti-slip pad. Base 1 is located to the left of base 2 7. Electric slides 2 and 3 are respectively mounted on base 1. The grinding wheel spindle 4 is mounted on electric slide 3. The cooling box... The cooling tank 18 is installed on the grinding wheel spindle 4. The inlet pipe 16 and outlet pipe 17 are respectively connected to the cooling tank 18. The cooling water circulates to cool the grinding wheel spindle 4 and reduce thermal deformation during processing. The grinding wheel drive assembly 31 is located on the rear side of the grinding wheel spindle 4 and is connected to the grinding wheel spindle 4 through a transmission mechanism. The output shaft of the grinding wheel spindle 4 is connected to the grinding wheel 5. The clamping assembly 8 for holding the bar stock 10 is fixedly installed on the base 2 7. The output shaft of the motor 9 is connected to the clamping assembly 8 and installed on the base 2 7. Motor 9 drives the clamping assembly 8 to rotate, jointly realizing the collaborative processing of grinding wheel 5 and bar stock 10. Synchronous follower bracket 6 is set on electric slide table 3, and fixed block 11 is installed on base 7 to support bar stock 10. Anti-slip pad is set on the contact surface between fixed block 11 and bar stock 10 to increase the friction between fixed block 11 and bar stock 10 and prevent bar stock 10 from sliding during processing. The synchronous follower bracket 6 and fixed block 11 provide stable support together. The upper end of fixed block 11 is provided with two protrusions 1. 50. The sliding frame 13 is provided with a first sliding groove 14 and a second sliding groove 15. Two protrusions 150 are located in the first sliding groove 14 and the second sliding groove 15 respectively. One end of the sliding frame 13 is rotatably connected to the translation block 120. The telescopic rod of the electric push rod 12 is connected to the translation block 120. The electric push rod 12 drives the sliding frame 13 to move through the translation block 120. The contact between the sliding frame 13 and the bar stock 10 further fixes the bar stock 10. The precise processing of the bar stock 10 by the grinding wheel 5 is achieved by the movement of the electric slide table 12 and the electric slide table 23.

[0021] In use, the bar stock 10 is first installed in the clamping assembly 8, which is fixed on the base 7. The bar stock 10 is rotated by the motor 9. The fixing block 11 is fixed on the base 7, and the synchronous follower bracket 6 is set on the electric slide table 3. The clamping assembly 8 and the synchronous follower bracket 6 jointly support the bar stock 10. The upper end of the fixing block 11 is provided with two protrusions 150. The sliding frame 13 is slidably connected to the protrusions 150 through the first slide groove 14 and the second slide groove 15, respectively. The electric push rod 12 drives the slide table 13. The moving frame 13 moves along the protrusion 150, so that the sliding frame 13 contacts the bar stock 10, further fixing the bar stock 10 and ensuring its stability. The electric slide table 12 and the electric slide table 23 work together to adjust the overall position of the device. The electric slide table 23 drives the grinding wheel spindle 4 and the synchronous follower bracket 6 to move left and right and back and forth. The grinding wheel spindle 4 achieves precise position adjustment through the electric slide table 23. The grinding wheel drive assembly 31 drives the grinding wheel spindle 4 through the transmission mechanism, so that the grinding wheel 5 performs rough grinding and fine grinding on the bar stock 10.

[0022] During processing, the cooling box 18 is installed on and surrounds the grinding wheel spindle 4. Coolant is circulated through the inlet pipe 16 and outlet pipe 17 to cool the grinding wheel spindle 4 and reduce thermal deformation during processing. The synchronous follower bracket 6 slides left and right via the electric slide table 3, allowing for flexible adjustment of its position according to the processing requirements of the bar stock 10, ensuring optimal support angle and contact point with the bar stock 10 throughout the processing. The fixing block 11 is firmly fixed to the base 7, serving as a stable support point. Its structural design ensures reliable contact with the bar stock 10. Together with the synchronous follower bracket 6, they form a dynamic and static support system, providing comprehensive stability for the bar stock 10. The anti-slip pads on the fixing block 11 further enhance the friction with the bar stock 10, effectively preventing the bar stock 10 from sliding or shifting during processing. Simultaneously, the electric push rod 12 drives the sliding frame 13 to move along the protrusions 150 on the fixing block 11 via the translation block 120. The two protrusions 150 are located in the first slide groove 14 and the second slide groove 15, respectively, forming additional fixing points to further press the bar stock 10, ensuring its stability during high-speed rotation and grinding. This multi-point support and fixing design significantly improves the stability of the bar stock 10 during high-speed processing, ensuring that it will not shift due to vibration or impact, thereby guaranteeing the processing accuracy of rough grinding and fine grinding, and ultimately achieving high-precision grinding of the bar stock 10.
