However, the components on the positioning device often affect the processing operations near the contact area, and the position of the ball-squeezing wheel needs to be disassembled and adjusted, which increases the processing time and reduces production efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a positioning device for processing a ball squeezing wheel of a tennis machine in view of the defects of the prior art, so as to solve the problems in the above-mentioned background technology.

[0004] A positioning device for processing a ball-squeezing wheel of a tennis machine comprises a workbench and a driving mechanism and a limiting mechanism mounted on the workbench. The limiting mechanism comprises a positioning disk, a bracket, an electric cylinder, a lower limiting portion, a roller, an upper limiting portion, a limiting plate and a roller. The positioning disk is mounted on the driving mechanism. There are two brackets symmetrically arranged about the center point of the positioning disk. The electric cylinder is mounted on the bracket. The lower limiting portion is mounted at the output end of the electric cylinder. A plurality of rollers are arranged in the middle of the lower limiting portion. The upper limiting portion is supported by studs and nuts. The limiting plate is mounted on the concave arc surface of the upper limiting portion. A plurality of rollers are arranged on the limiting plate.

[0005] By adopting the above technical solution, the ball-extruding wheel can be quickly and conveniently limited, and the position of the ball-extruding wheel can be adjusted without disassembly, so that the position of the ball-extruding wheel to be processed is moved to the bottom of the external processing equipment, and the parts for positioning the ball-extruding wheel do not need to rotate accordingly, which can avoid affecting the normal processing of the ball-extruding wheel by the processing equipment due to the positioning part.

[0006] The driving mechanism includes a toothed disc, a gear and a reduction motor. The gear is installed at the output end of the reduction motor. The toothed disc is rotatably installed on the workbench and meshes with the gear for transmission.

[0007] By adopting the above technical solution, the position of the ball squeezing wheel is adjusted.

[0008] The positioning disc is coaxially mounted on the gear disc.

[0009] By adopting the above technical solution, it is ensured that the positioning disc drives the ball squeezing wheel to rotate synchronously.

[0010] Support rods sliding along the bracket are also installed on both sides of the lower limit portion.

[0011] By adopting the above technical solution, the lower limit part is well supported.

[0012] The lower limit part, upper limit part and limit plate are all arranged in arc-shaped structures. The roller is installed in the middle of the lower limit part and is distributed along the arc direction of the lower limit part. Its side protrudes from the lower limit part. The roller is arranged to protrude from the limit plate and is distributed along the arc direction of the limit plate.

[0013] By adopting the above technical solution, the ball squeezing wheel is fitted for limitation.

[0014] The beneficial effects of the positioning device for processing the ball squeezing wheel of the tennis machine of the utility model are:

[0015] Place the ball-extruding wheel on the positioning plate and limit its bottom. Then, drive the electric cylinder to push the lower limit part so that the roller is close to the side of the ball-extruding wheel, and turn the nut on the stud to adjust the height of the upper limit part so that the bottom side of the roller is close to the edge of the upper end surface of the ball-extruding wheel. The height of the upper limit part is limited, which is convenient for quickly limiting the ball-extruding wheel. The position of the ball-extruding wheel can be adjusted without disassembly, so that the position of the ball-extruding wheel to be processed is moved to the bottom of the external processing equipment. The parts for positioning the ball-extruding wheel do not need to rotate accordingly, which can avoid affecting the normal processing of the ball-extruding wheel by the processing equipment due to the positioning part.

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0020] Reference Figure 1-2A positioning device for processing a ball-squeezing wheel of a tennis machine comprises a workbench 1 and a driving mechanism and a limiting mechanism mounted on the workbench 1. The limiting mechanism comprises a positioning plate 5, a bracket 6, an electric cylinder 7, a lower limiting portion 8, a roller 10, an upper limiting portion 11, a limiting plate 12 and a roller 13. The positioning plate 5 is mounted on the driving mechanism. There are two brackets 6, which are symmetrically arranged about the center point of the positioning plate 5. The electric cylinder 7 is mounted on the bracket 6. The lower limiting portion 8 is mounted at the output end of the electric cylinder 7. A plurality of rollers 10 are arranged in the middle of the lower limiting portion 8. The upper limiting portion 11 is supported by a stud 14 and a nut 15. The limiting plate 12 is mounted on the concave arc surface of the upper limiting portion 11. A plurality of rollers 13 are arranged on the limiting plate 12.

[0021] The driving mechanism includes a gear disc 2, a gear 3 and a reduction motor 4. The gear 3 is installed at the output end of the reduction motor 4. The gear disc 2 is rotatably installed on the workbench 1 and meshes with the gear 3 for transmission.

[0022] The positioning disc 5 is coaxially mounted on the toothed disc 2; the structure of the positioning disc 5 is adapted to the structure of the ball-extruding wheel 16, so that the ball-extruding wheel 16 can be directly placed on the positioning disc 5. The mounting shaft in the middle of the positioning disc 5 can pass through the keyway in the middle of the ball-extruding wheel 16, and when the positioning disc 5 is inserted into the keyway of the ball-extruding wheel 16, its top end does not exceed the keyway of the ball-extruding wheel 16.

[0023] Support rods 9 that slide along the bracket 6 are also installed on both sides of the lower limit portion 8; ensuring the stability of the movement of the lower limit portion 8; the lower limit portion 8, the upper limit portion 11 and the limit plate 12 are all arranged in an arc-shaped structure, the roller 10 is installed in the middle of the lower limit portion 8, distributed along the arc direction of the lower limit portion 8, and its side protrudes from the lower limit portion 8. The roller 13 is arranged to protrude from the limit plate 12 and distributed along the arc direction of the limit plate 12;

[0024] The design is based on the curvature of the ball-extruding wheel 16 so that the roller 10 can be stably fitted on the side of the ball-extruding wheel 16, and the roller 13 can be stably fitted on the side of the upper end surface of the ball-extruding wheel 16, so that the ball-extruding wheel 16 can rotate smoothly.

[0025] Working principle: Place the ball-squeezing wheel 16 on the positioning plate 5 and limit its bottom. Then drive the electric cylinder 7 to push the lower limit part 8 so that the roller 10 is close to the side of the ball-squeezing wheel 16. Turn the nut 15 on the stud 14 to adjust the height of the upper limit part 11 so that the bottom side of the roller 13 is in contact with the upper end edge of the ball-squeezing wheel 16 to limit the height of the upper limit part 11.

[0026] After the ball-extruding wheel 16 is defined, the reduction motor 4 can be driven to rotate the toothed disc 2 through the gear 3, and the toothed disc 2 can synchronously drive the ball-extruding wheel 16 to rotate through the positioning disc 5, so that the processing position of the ball-extruding wheel 16 is moved to the bottom of the external processing equipment, and processing can be carried out;

[0027] The device can quickly and conveniently limit the ball-extruding wheel 16, and the position of the ball-extruding wheel 16 can be adjusted without disassembly, so that the position of the ball-extruding wheel 16 to be processed is moved to the bottom of the external processing equipment, and the parts for positioning the ball-extruding wheel 16 do not need to rotate with it, so as to avoid the positioning part affecting the normal processing of the ball-extruding wheel 16 by the processing equipment.

[0028] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
