Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary mechanisms for drilling equipment, and in particular to a positioning mechanism for a racket three-way drilling machine. Background Technology

[0002] Because of the stringing requirements, racket tee holes usually need to be drilled with a drilling machine. In order to facilitate mechanized production, the general processing procedure is to first position the racket frame and then drill precise holes.

[0003] Patent CN111152293B discloses a drilling device for a badminton racket three-way joint, including a support foot, a fixing platform, and a machine housing. The support foot is installed at the four corners of the bottom of the fixing platform. Two identical support plates are installed at the top center of the fixing platform. The machine housing is located on top of the support plates and is connected to the support plates by screws. A clamping mechanism, a pushing mechanism, and a feeding mechanism are sequentially installed at one end of the top of the fixing platform. A blocking mechanism is provided on one side of the support plate. The two ends of the blocking mechanism are respectively connected to the two identical support plates by screws. By controlling the machine, the badminton racket is fixed, eliminating the need for a person to hold the badminton racket by hand, thus preventing injury and ensuring high safety. Furthermore, the machine can automatically feed the racket, greatly reducing labor costs.

[0004] When using the above device, the racket that has already been punched needs to be removed from the clamping mechanism before the racket to be punched is installed on the clamping mechanism. During this process, the equipment is in a stopped state, the positioning process is inefficient, and the punching efficiency is affected. Utility Model Content

They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0027] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0028] See Figure 1 As shown in the figure, the positioning mechanism of a racket three-way punching machine according to an embodiment of the present invention includes a base 1, a lifting mechanism 2, an intermittent rotation mechanism 3, and several clamps 4.

[0029] See Figure 2 As shown, the intermittent rotation mechanism 3 includes a horizontal plate 301. A cam divider 302 and a motor for driving the cam divider 302 are fixedly mounted on the top of the horizontal plate 301. A plum blossom mold 305 is fixedly mounted on the rotating end of the cam divider 302, and a clamp 4 is set on the plum blossom mold 305. When the motor drives the cam divider 302 to rotate intermittently, rotational feeding is achieved.

[0030] See Figure 3 As shown, the fixture 4 includes a first arc-shaped plate 401 and a second arc-shaped plate 402. The first arc-shaped plate 401 is fixedly mounted on the plum blossom mold 305. A guide rod 4011 is fixedly connected to the bottom of the first arc-shaped plate 401. A sliding groove 4021 is provided at the bottom of the second arc-shaped plate 402. The second arc-shaped plate 402 is slidably mounted on the guide rod 4011 through the sliding groove 4021. An elastic sheet 403 is provided between the first arc-shaped plate 401 and the second arc-shaped plate 402. Under the elastic force of the elastic sheet 403, the second arc-shaped plate 402 can move away from the first arc-shaped plate 401. In order to facilitate the limiting of the racket frame and facilitate the discharge of waste generated by drilling, an arc-shaped limiting groove 4012 is provided on the side of the first arc-shaped plate 401 away from the second arc-shaped plate 402. A number of racket shaft supports 306 are provided on the edge of the plum blossom mold 305 corresponding to the arc-shaped limiting groove 4012 to support the racket shaft.

[0031] In use, the racket frame is fitted onto the first arc-shaped plate 401 and the second arc-shaped plate 402, with the first and second arc-shaped plates 401 and 402 positioned inside the racket frame. The elasticity of the elastic sheet 403 secures the racket frame with the first and second arc-shaped plates 401 and 402, while simultaneously placing the part of the racket frame requiring a hole within the arc-shaped limiting groove 4012. When the racket frame needs to be removed, simply pull the racket frame towards the first arc-shaped plate 401. At this time, the second arc-shaped plate 402 moves towards the first arc-shaped plate 401, and the racket frame can be lifted upwards to disassemble it.

[0032] See Figure 2 As shown, the lifting mechanism 2 includes a cylinder 201, which is fixedly installed on the top of the base 1. A top block is fixedly installed on the top of the piston rod of the cylinder 201, and the top block abuts against the bottom of the horizontal plate 301. By controlling the extension and retraction of the piston rod of the cylinder 201, the intermittent rotation mechanism 3 can be driven to lift and lower.

[0033] To ensure that the intermittent rotation mechanism 3 can rise and fall stably, side plates 101 are fixedly installed on both opposite sides of the base 1. A slide rail 102 is fixedly installed on the inner side of the side plate 101. A slider 304 is slidably installed on the slide rail 102. Side slide plates 303 are fixedly connected to both opposite sides of the horizontal plate 301. The slider 304 is fixedly connected to one side of the side slide plate 303.

[0034] In order to achieve automatic operation of the equipment, the positioning mechanism of the racket three-way punching machine in this embodiment of the utility model is also provided with a control box 6. The control box 6 is equipped with a PLC controller, a motor, a solenoid valve that controls the extension and retraction of the piston rod of the cylinder 201, and is controlled by the PLC controller.

[0035] In use, the racket frame is fitted onto the first arc plate 401 and the second arc plate 402, so that the first arc plate 401 and the second arc plate 402 are located inside the racket frame. The elasticity of the elastic sheet 403 fixes the badminton racket to the first arc plate 401 and the second arc plate 402. At the same time, the part of the racket frame that needs to be drilled is placed at the arc-shaped limiting groove 4012. The cam divider 302 drives the clamp 4 holding the racket frame to move and rotate so as to drill holes one by one.

[0036] The above description illustrates the basic principles of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only for illustrating the principles of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
