Description

Technical Field

[0001] This utility model relates to the field of tennis machine plastic parts processing technology, and in particular to an auxiliary device for positioning the opening of the ball ejection shell of a tennis machine. Background Technology

[0002] Tennis machines play an important role in tennis training and fitness. They mainly use a launching device to launch tennis balls from a storage tank to a specific area via a control unit. Through the cooperation of sensors and control units, they can launch balls with different forces and angles to different areas to achieve training and fitness effects.

[0003] The ball served from a tennis machine needs to pass through the ball outlet, which is generally an injection-molded part. To facilitate installation, mounting holes need to be cut into the edge of the injection-molded ball outlet shell. Directly machining the mounting holes during the injection molding process not only increases the complexity of the mold and the difficulty of mold design and processing, but also increases the mold production cost. Moreover, directly cutting the mounting holes during production can easily cause flash to form inside the holes. Therefore, the mounting holes need to be machined separately. When machining the mounting holes, providing sufficient limits and positioning can facilitate the cutting of the mounting holes, and auxiliary equipment is needed to help the hole-cutting equipment to be effectively positioned at the hole-cutting position. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing an auxiliary device for positioning the opening of the ball ejection shell of a tennis machine.

[0005] This utility model is achieved through the following technical solution:

The positioning assembly is installed on the top of the base assembly, and the workpiece is clamped on the top of the positioning assembly. The base assembly includes a mounting base, a slide rail, a sliding seat, a drilling machine mounting plate, and a limiting strip. The slide rail is fixedly installed on the top of one end of the mounting base, the sliding seat is movably connected to the slide rail, the drilling machine mounting plate is movably installed on the top of the sliding seat, and the limiting strip is fixedly installed on one side of the drilling machine mounting plate.

The card seat is fixedly disposed on the top of the positioning seat, the support block is installed on the top of the card seat, and the limiting support platform is fixedly disposed at one end of the positioning seat.

[0008] The positioning component mainly limits and supports the workpiece, thereby facilitating the drilling equipment to perform drilling work in a fixed position.

[0009] In a preferred embodiment of the present invention, one end of the workpiece is provided with an installation hole, the top of the limiting support platform is provided with a machining deflection hole that cooperates with it, and the side of the limiting support platform is provided with a limiting slot that cooperates with the limiting insert according to the position of the installation hole.

[0010] The tool hole facilitates the drilling equipment's processing, avoids interference between the limit support table and the processing equipment, and the limit slot allows the drilling machine to move to the appropriate position and be effectively positioned, thereby ensuring the drilling position.

[0011] In a preferred embodiment of the present invention, the top of the card holder is provided with a card groove that mates with the bottom of the support block, and the top of the support block is in contact with the inner side of the top of the workpiece;

[0012] The mounting bracket and the support block are connected by screws, which reduces production difficulty, reduces material loss, and facilitates processing. The support block provides effective support to the inner top of the workpiece. The support block can also be clamped to the outer side of the bottom rib plate of the workpiece to achieve a limiting effect.

[0013] In a preferred embodiment of the present invention, the bottom of the sliding seat is provided with a sliding groove that cooperates with the slide rail, the bottom of the drilling machine mounting plate is provided with a retaining strip, and the top of the sliding seat is provided with a guide groove that cooperates with the drilling machine mounting plate.

[0022] like Figure 1-4 The tennis ball ejection shell opening positioning auxiliary device shown includes a base assembly 1, a positioning assembly 2, and a workpiece 3. The positioning assembly 2 is installed on the top of the base assembly 1, and the workpiece 3 is clamped on the top of the positioning assembly 2. The base assembly 1 includes a mounting base 11, a slide rail 12, a sliding seat 13, a drilling machine mounting plate 14, and a limiting strip 15. The slide rail 12 is fixedly installed on the top of one end of the mounting base 11, the sliding seat 13 is movably connected to the slide rail 12, the drilling machine mounting plate 14 is movably installed on the top of the sliding seat 13, and the limiting strip 15 is fixedly installed on one side of the drilling machine mounting plate 14.

[0023] Specifically, the positioning component 2 includes a positioning seat 21, a retaining seat 22, a support block 23, and a limiting support platform 24. The retaining seat 22 is fixedly mounted on the top of the positioning seat 21, the support block 23 is mounted on the top of the retaining seat 22, and the limiting support platform 24 is fixedly mounted on one end of the positioning seat 21. One end of the workpiece 3 is provided with an installation hole. The top of the limiting support platform 24 is provided with a machining deflection hole that cooperates with it. The side of the limiting support platform 24 is provided with a limiting slot that cooperates with the limiting insert 15 according to the position of the installation hole. The top of the retaining seat 22 is provided with a slot that cooperates with the bottom of the support block 23. The top of the support block 23 is attached to the inner side of the top of the workpiece 3. The bottom of the sliding seat 13 is provided with a sliding groove that cooperates with the slide rail 12. The bottom of the drilling machine mounting plate 14 is provided with a retaining strip, and the top of the sliding seat 13 is provided with a guide slot that cooperates with the drilling machine mounting plate 14.

[0024] In this embodiment, the support block 23 is fixed to the top slot of the card seat 22 by screws. The support block 23 and the card seat 22 are separate structures, which effectively reduces the processing difficulty and the amount of material used. After the workpiece 3 is installed, the assembled support block 23 will clamp and limit the bottom rib plate of the workpiece 3 and provide effective support on the inner side of the top of the workpiece 3. One bottom end of the workpiece 3 contacts the top of the limiting support platform 24 and is limited by the top slot of the limiting support platform 24, thereby realizing the limiting and positioning effect of the workpiece 3.

[0025] Furthermore, the drilling machine is installed at a suitable position on the top of the drilling machine mounting plate 14, and the sliding seat 13 is slid back and forth on the top of the slide rail 12 to adjust the position of the drilling machine. Then, the position of the drilling machine mounting plate 14 is changed by sliding it left and right, so that the limiting insert 15 on one side of the drilling machine mounting plate 14 is engaged in the limiting slot on the outer side of the corresponding limiting support table 24. At this time, the processing end of the drilling machine will be located on the top outer side of the mounting hole of the workpiece 3. Pressing down the drilling machine handle can realize the drilling operation. Through the cooperation between the limiting slot on the top outer side of the limiting support table 24 and the limiting insert 15 on one side of the drilling machine mounting plate 14, the processing position can be quickly positioned and switched, which is convenient for drilling operation.
