Description

Technical Field

[0001] This utility model relates to the field of chamfering mold parts, and in particular to an automatic chamfering device for mold parts. Background Technology

[0002] The core technology behind chamfering of parts is to solve edge defects, assembly difficulties, and safety issues after part processing. Its development has been synchronized with the demands of mechanical manufacturing for precision, efficiency, and reliability. After parts are processed by cutting, stamping, etc., burrs, flash, and sharp corners are easily generated on the edges. These defects can lead to a decrease in the dimensional accuracy of the parts and may also scratch operators or damage mating components during subsequent assembly or use.

[0003] Existing technologies, such as the utility model patent with publication number CN220679563U, disclose a chamfering machine for mechanical parts. A rotating screw is rotatably mounted on the inner side of the mounting frame via bearings. A lifting sleeve is movably sleeved on the top surface of the outer side of the rotating screw. Connecting rods are fixedly mounted on both ends of the lifting sleeve, and a placement frame is fixedly mounted on the side surface of the connecting rods. An adjusting bolt is threaded to the middle of the side of the placement frame. This utility model's technical solution, through the adjustment of the position of the first abutment plate by the adjusting bolt and the transmission action of the rotating screw on the lifting sleeve, ensures that the outer sides of the first and second abutment plates can conform to the cylindrical mechanical parts for reinforcement and limiting. This allows the mechanical parts placed inside the placement frame to be simultaneously adjusted vertically, enabling rapid and simultaneous adjustment of the mechanical parts' processing position, reducing the labor required for operator adjustments.

[0004] In industrial production, it has been found that traditional chamfering equipment is prone to drill bit damage during repeated processing. Improper disassembly during rapid drill bit replacement can also damage the drill bit or chuck, affecting operational accuracy and quality. With the development of industrial automation, higher demands are placed on every stage of the production process, including drill bit disassembly. Traditional disassembly methods cannot meet the requirements of efficient and rapid tool change in automated production lines. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the drill bit or drill chuck is damaged when tools are used to disassemble traditional mold parts during the chamfering process.

[0006] To solve the above technical problems, this utility model provides an automatic chamfering device for mold parts, comprising: a base and connecting rails. An electrical control cabinet is fixedly connected to the upper surface of the base. Two fixed rails are fixedly connected to the upper surface of the base. A common support plate is slidably connected to the upper surfaces of the two fixed rails. A rotating column is threadedly connected to the side wall surface of the support plate. A motor is fixedly connected to the upper surface of the support plate. A quick-release device is installed at the output end of the motor. The lower surface of the connecting rail is fixedly connected to the upper surface of the base. A sliding plate is slidably connected to the upper surface of the connecting rail. A worktable is fixedly connected to the upper surface of the sliding plate. The quick-release device includes a drill bit body and a sleeve. The bottom surface of the sleeve is fixedly connected to the output end of the motor. The arc surface of the sleeve is provided with a connecting groove, and the arc surface of the drill bit body is provided with a fixing groove. A locking pin is slidably connected to the bottom surface of the connecting groove. The surface of the locking pin is slidably connected to the inner wall surface of the fixing groove. Adjusting plates are fixedly connected to both sides of the locking pin. First springs are fixedly connected to the lower surfaces of the two adjusting plates. The bottom ends of the two first springs are fixedly connected to the inner wall surface of the connecting groove. A limiting block is fixedly connected to the arc surface of the sleeve. A threaded rod is threadedly connected to the surface of the limiting block. A spacer is rotatably connected to the end of the threaded rod near the connecting groove. The surface of the spacer abuts against the upper surface of the locking pin.

[0007] The effect achieved by the above components is as follows: during the process of quickly disassembling the drill bit body, the drill bit body can be quickly disassembled using the quick-release device. At this time, the drill bit body can be fixed to the inner wall of the sleeve by the engagement of the chuck surface with the inner wall of the connecting groove and the inner wall of the fixing groove of the arc surface of the drill bit body. By using the abutment of the spacer block rotatably connected to the threaded rod with the chuck, the chuck can be prevented from moving, thus ensuring the stability of the drill bit body.

[0008] Preferably, the arc surface of the drill bit body is provided with a plurality of slots, and the inner arc surface of the sleeve is fixedly connected with a plurality of locking blocks, the locking blocks engaging with the slots.

[0009] The effect achieved by the above-mentioned components is that the engagement of several slots and blocks on the arc surface of the drill bit body can assist in the installation and fixation of the drill bit body.

[0010] Preferably, the upper surface of the connecting groove is fixedly connected to two fixing posts, the arc surface of the fixing posts is slidably connected to the inner wall of the first spring, and the arc surface of the fixing posts slides through the surface of the adjusting plate.

[0011] The effect achieved by the above components is that by using a fixed post that is slidably connected to the inner wall surface of the first spring, the spring will not bend during movement, thus extending the service life of the spring.

[0012] Preferably, the spacer has a conical cross-section and is a cemented carbide block.

[0013] The effect achieved by the above components is that by using hard metal spacers with a conical cross-section, the wear of the spacers can be reduced, thus lowering costs.

[0014] Preferably, a fixing device is fixedly connected to the upper surface of the worktable. The fixing device includes an auxiliary rail, the lower surface of which is fixedly connected to the upper surface of the worktable. A first caliper and a second caliper are slidably connected to the inner wall of the auxiliary rail. An auxiliary block is fixedly connected to the upper surface of both the first caliper and the second caliper. Several positioning grooves are formed on the side wall surface of the auxiliary rail. A rotating block is rotatably connected to the inner wall surface of the auxiliary block. Several auxiliary grooves are formed on the upper surface of the rotating block. A sliding block is slidably connected to the surface of the rotating block. A rotating rod is threadedly connected to the upper surface of the sliding block. The lower surface of the rotating rod engages with the surface of the auxiliary groove. A driven block is fixedly connected to the lower surface of the sliding block. An adjusting rod is threadedly connected to the surface of the driven block. A positioning block is rotatably connected to the end of the adjusting rod near the auxiliary rail. The end of the positioning block near the auxiliary rail engages with the surface of several positioning grooves. An adjusting hole is formed on the right-angled side of the worktable. The cross-sectional dimensions of the adjusting hole are adapted to the cross-sectional dimensions of the drill bit body.

[0015] The effect achieved by the above components is as follows: during the process of fixing the parts, the fixing device can be used to fix the parts. At this time, the parts can be clamped by the movement of the first caliper and the second caliper. The position of the sliding block can be fixed by the engagement of the rotating rod with the surface of several auxiliary grooves. The position of the first caliper and the second caliper can be fixed by the engagement between the positioning block and the positioning groove, thereby making the first caliper and the second caliper clamp the parts.

[0016] Preferably, the first caliper and the second caliper have a plurality of connecting grooves on their respective surfaces that are close to each other, and the plurality of connecting grooves are evenly distributed on the sidewall surfaces of the first caliper and the second caliper.

[0017] The effect achieved by the above components is that by using the opening of the connecting groove, the friction between the first and second calipers and the parts is increased, which facilitates the clamping of the parts.

[0018] Preferably, an auxiliary pad is fixedly connected to the upper surface of the workbench, and the position of the auxiliary pad corresponds to that of the first caliper and the second caliper.

[0019] The effect achieved by the above components is that by using auxiliary pads, the parts will not slide, thus facilitating their fixation.

[0020] Compared with related technologies, the automatic chamfering device for mold parts provided by this utility model has the following advantages:

[0021] This utility model provides an automatic chamfering device for mold parts. When it is necessary to quickly disassemble the drill bit body, a quick-release device can be used to quickly disassemble the drill bit body. At this time, the sleeve is fixed to the drill bit body by the locking pin. Rotating the threaded rod will make the surface of the partition block abut against the upper surface of the locking pin, so that the locking pin cannot move, thereby quickly fixing the drill bit body. The locking of the locking block and the locking groove can assist in fixing the drill bit body.

[0022] When it is necessary to fix the parts, a fixing device can be used to fix the parts. At this time, by moving the first caliper and the second caliper, the parts can be clamped. The position of the sliding block is fixed by using the rotating rod, so that the surface of the sliding block abuts against the surface of the auxiliary rail. Rotating the adjusting rod makes the positioning block engage with the positioning groove, preventing the first caliper and the second caliper from shaking. By using the auxiliary pad, the fixing of the parts can be assisted. Attached Figure Description
