Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a universal adjustable small parts grinding clamp. Background Technology

[0002] Grinding of small parts is a key technology in the field of precision machining. By using high-precision grinding tools to cut the surface of tiny workpieces, high dimensional accuracy and high surface finish can be achieved. It is widely used in industries such as electronics, aerospace, and medical devices.

[0003] Utility model patent CN211565533U discloses a multifunctional grinding fixture, which includes a spindle, a V-shaped reference block, and a U-shaped clamping block. The spindle is provided with a small chuck reference hole along the spindle axis and a first thread fixing hole along the spindle radially. The first thread fixing hole is connected to the small chuck reference hole. The end face of the spindle has a dovetail groove along the spindle radially. The V-shaped reference block is provided with a dovetail-shaped protrusion that mates with the dovetail groove. The V-shaped reference block is also provided with a fastening groove. Both ends of the U-shaped clamping block have inward protrusions with fastening steps that mate with the fastening groove. The U-shaped clamping block is provided with bolts for fastening the V-shaped reference block, the U-shaped clamping block, and the part clamped between the V-shaped reference block and the U-shaped clamping block. This invention utilizes a small chuck reference hole on the spindle, along with a core sleeve, a V-shaped reference block, and a U-shaped clamping block, to clamp parts of various sizes and shapes, providing a multi-functional grinding fixture that greatly expands its applicability.

[0004] This multi-functional grinding fixture can only achieve limited angle adjustment by shims between the adjusting step and the support block, and cannot achieve free and flexible adjustment of multiple angles, making it difficult to meet the grinding needs of parts with complex angles. At the same time, the fixture uses V-grooves, fastening grooves and fastening steps to cooperate with fastening steps and bolts to fasten parts, but it is not designed with a convenient adjustment structure for small parts of different sizes, nor does it have the function of replacing clamping parts of different specifications, making it difficult to adapt to the clamping and fixing of small parts of various sizes. In view of this, we propose a universal adjustable small parts grinding fixture. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1-8 A universal adjustable small parts grinding clamp includes a grinding table 100, which includes a base 110 and an adjusting seat 120 hinged to the front edge of the base 110. A stop post 122 is fixed to the rear edge of the bottom surface of the adjusting seat 120. When the stop post 122 abuts against the top surface of the base 110, the top surface of the adjusting seat 120 is parallel to the bottom surface of the base 110. By inserting pads of different thicknesses under the stop post 122, the angle between the adjusting seat 120 and the base 110 can be changed, so that the adjusting seat 120 can form different angles of inclination on the base 110, thereby realizing the flexible adjustment of the tilt angle of the part during the grinding process.

[0041] like Figure 1 and Figure 3As shown, in this invention, a rotary clamping mechanism 200 is rotatably connected to the top of the grinding table 100. The grinding table 100 can adjust the tilt angle of the part, and the rotary clamping mechanism 200 can drive the part to rotate circumferentially. The rotary clamping mechanism 200 includes a rotating component 210 mounted on the grinding table 100 and a pair of clamping components 220 for clamping the part. The cooperation between the rotary clamping mechanism 200 and the grinding table 100 provides multiple angle adjustment methods for the part. The tilt angle can be adjusted by the grinding table 100, and circumferential rotation can be achieved by the rotary clamping mechanism 200, meeting different processing requirements.

[0042] like Figure 2 and Figure 4 As shown, specifically, the top of the adjusting seat 120 is provided with a protruding post 121, and the rotating assembly 210 includes a turntable 211 sleeved on the outside of the protruding post 121 and a locking screw 212 that is threaded laterally connected to the turntable 211. The bottom surface of the turntable 211 is provided with a shaft hole 2111, and the protruding post 121 extends into the shaft hole 2111. The turntable 211 rotates on the protruding post 121 through the shaft hole 2111. The outer surface of the turntable 211 is provided with a threaded hole for mounting the clamping screw 212. The threaded hole is connected to the shaft hole 2111. The first end of the clamping screw 212 is provided with a first handle 2121. The end of the clamping screw 212 can abut against the protrusion 121. The cooperation between the turntable 211 and the protrusion 121 realizes the rotation function of the rotating assembly 210. The setting of the clamping screw 212 and the first handle 2121 allows the operator to rotate the first handle 2121 to drive the clamping screw 212 to move, and fix the turntable 211 at a specified angle position of the protrusion 121, ensuring the stability of the part position during rotational processing.

[0043] like Figure 1 and Figure 5 As shown, the clamping assembly 220 further includes a fixed base 221 fixed to the rotating assembly 210, an adjusting screw 222 that extends laterally through the fixed base 221 and is threadedly connected to the fixed base 221, a mounting base 223 hooked to the end of the adjusting screw 222, and a clamping head 224 mounted on the end of the mounting base 223. By rotating the adjusting screw 222, the clamping head 224 can be brought into contact with the part. By bringing the clamping heads 224 on both clamping assemblies 220 into contact with the part, the part can be clamped. The threaded connection between the adjusting screw 222 and the fixed base 221, together with the mounting base 223 and the clamping head 224, allows the operator to precisely adjust the position of the clamping head 224 by rotating the adjusting screw 222, thereby achieving stable clamping of parts of different sizes.

[0044] like Figure 5 and Figure 6As shown, the end of the adjusting screw 222 is provided with a hanging rod 2221 with a T-shaped cross-section, and the rear end face of the mounting base 223 is provided with a hanging groove 2233 with a T-shaped cross-section. The hanging rod 2221 is hung into the hanging groove 2233. The beginning end of the adjusting screw 222 is provided with a second handle 2222 for easy operation by the operator. The T-shaped fit structure between the hanging rod 2221 and the hanging groove 2233 enhances the stability of the connection while ensuring that the mounting base 223 can move with the adjusting screw 222.

[0045] like Figure 5 and Figure 6 As shown, it is worth noting that a pair of guide rods 2234 are fixed at the rear end face of the mounting base 223. The guide rods 2234 pass through the fixed base 221 and are slidably connected to the fixed base 221. The slidable connection between the guide rods 2234 and the fixed base 221 provides guidance for the movement of the mounting base 223, enabling the mounting base 223 to move smoothly under the drive of the adjusting screw 222, avoiding deviation and ensuring the accuracy of the clamping head 224 in clamping the part.

[0046] like Figure 5-7 As shown, it is worth noting that a protruding plate 2231 is provided at the bottom edge of the front end face of the mounting base 223, and a tailstock 2241 is provided at the rear end position of the clamping head 224. A slot 2232 is formed at the rear end edge of the top surface of the protruding plate 2231, and a groove 2242 is formed at the rear end edge of the bottom surface of the tailstock 2241. A protruding edge 2243 is provided at the bottom of the groove at the rear end edge of the groove 2242. The protruding edge 2243 can be inserted into the slot 2232. The tailstock 2241 is detachably connected to the protruding plate 2231 by bolts, so that the clamping head 224 is detachably connected to the mounting base 223. The cooperation of the protruding plate 2231, the slot 2232, the tailstock 2241, the groove 2242, the protruding edge 2243, and the bolts realizes the detachable connection of the clamping head 224 to the mounting base 223.

[0047] like Figure 8 As shown, it should be added that the clamping assembly 220 is equipped with multiple clamping heads 224 of different thicknesses. The inclusion of multiple clamping heads 224 of different thicknesses further enhances the adaptability of the clamping assembly 220 to small parts of different sizes. By replacing the clamping head 224 of appropriate thickness, it can be ensured that various small parts can be firmly clamped.

[0048] In this embodiment, the universal adjustable small parts grinding chuck is used as follows: First, according to the required tilt angle of the part, a pad of appropriate thickness is placed under the abutment 122, and the tilt angle of the adjusting seat 120 on the base 110 is adjusted. Then, the part is placed between the two clamping components 220. By rotating the second handle 2222, the adjusting screw 222 is rotated, causing the clamping head 224 to move and abut against the part, completing the initial clamping of the part. Next, if the current clamping head 224 is not suitable for the part size, the clamping head 224 can be removed from the mounting base 223 by removing the bolts, and a clamping head 224 of appropriate thickness can be replaced and reinstalled to clamp the part. Finally, according to the processing requirements of the part, the first handle 2121 is rotated to loosen the abutment screw 212, and the turntable 211 is rotated to adjust the circumferential angle of the part. After adjustment, the first handle 2121 is rotated again to make the abutment screw 212 abut against the protrusion 121 to fix the turntable 211, and the grinding process of the part can begin.
