Description

Technical Field

[0001] The utility model relates to the technical field of volleyball production, in particular to a positioning device for volleyball production. Background Art

[0002] Volleyball is a ball sport. The court is rectangular with a high net in the middle. The two teams (six players each) occupy one side of the court. The players use their hands to hit the ball over the net. The ball used in volleyball is made of sheepskin or artificial leather as the shell and rubber as the bladder. It is similar in size to a football.

[0003] During the production of volleyballs, they need to be positioned to ensure that they will not be displaced or misplaced, thereby ensuring the stability and consistency of the production process. During the positioning process of the volleyballs, most of the currently available positioning devices position the volleyballs through the left and right sides, and the two-side positioning method will also cause the volleyballs to slightly roll or rotate. When the volleyballs roll during production, they will be displaced or misplaced, resulting in the size, shape and weight of the volleyballs not meeting the specification requirements. To this end, we propose a positioning device for volleyball production to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a positioning device for volleyball production, which has the advantage of being able to clamp the volleyball in production on four sides, thereby solving the problem of displacement or misalignment of the volleyball due to unstable positioning during production.

[0006] The positioning assembly includes a servo motor fixed on the lower surface of the positioning plate, the output shaft of the servo motor is fixed with a driving sprocket, the outer surface of the driving sprocket is transmission-connected with a transmission chain, the end of the transmission chain away from the driving sprocket is transmission-connected with a driven sprocket, the inner circumferential wall of the driven sprocket is fixed with a first threaded rod, the outer surface of the first threaded rod is fixed with a second bevel gear, and the bottom surface of the second bevel gear is meshed with the first bevel gear.

[0007] Furthermore, the directions of the threads opened at both ends of the outer surfaces of the first threaded rod and the second threaded rod are opposite, and the two groups of positioning blocks are respectively arranged on the outer surfaces of the first threaded rod and the second threaded rod and are threadedly connected thereto.

[0008] Furthermore, the positioning plate is provided with four long holes for the positioning blocks to move, and two limit blocks are fixed on each positioning block. Limit grooves are also provided at both ends of the long holes, and the two limit blocks are respectively located inside the limit grooves and are slidably connected thereto.

[0009] Furthermore, anti-skid pads are fixed to opposite ends of the four positioning clamps, the anti-skid pads are soft, and a plurality of anti-skid grooves equidistantly distributed are formed on the anti-skid pads.

[0010] Furthermore, the buffer assembly includes a sleeve fixed between the four positioning blocks, a sleeve rod is sleeved inside the sleeve, and the buffer assembly also includes a spring fixed between the four positioning blocks.

[0011] Furthermore, the four springs are respectively sleeved with the four sleeves and sleeve rods, and opposite ends of the four springs are respectively fixed to opposite ends of the four positioning clamps.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 In this embodiment, a positioning device for volleyball production includes a positioning plate 1, two groups of positioning blocks 2, each with two positioning blocks, and two groups of positioning clamps 3, each with two positioning clamps. In addition, anti-skid pads are fixed at opposite ends of the four positioning clamps 3. The anti-skid pads are soft and have multiple anti-skid grooves equidistantly distributed on the anti-skid pads, which can effectively avoid the problem of volleyball sliding during positioning. The positioning plate 1 is provided with four long holes for the positioning blocks 2 to move, and each positioning block 2 is fixed with two limit blocks. Limiting grooves are also provided at both ends of the long hole. The two limit blocks are respectively located inside the limiting grooves and are slidably connected thereto. A positioning component is provided on the bottom surface of the positioning plate 1, and a buffer component is provided on the positioning block 2.

[0021] By setting up a positioning component, the four sides of the volleyball can be positioned. The four-sided positioning method can effectively avoid the problem of the volleyball slightly rotating during the positioning process causing the produced volleyball to have substandard size. At the same time, by setting up a buffer component, when the volleyball is clamped, the problem of the volleyball being damaged due to excessive clamping force can be effectively avoided.

[0022] See also Figure 2 In order to clamp and position the volleyball on all sides, the positioning assembly in this embodiment includes a servo motor 4 fixed on the lower surface of the positioning plate 1, the output shaft of the servo motor 4 is fixed with a driving sprocket 5, the outer surface of the driving sprocket 5 is transmission-connected with a transmission chain 6, the end of the transmission chain 6 away from the driving sprocket 5 is transmission-connected with a driven sprocket 7, the inner circumferential wall of the driven sprocket 7 is fixed with a first threaded rod 8, the outer surface of the first threaded rod 8 is fixed with a second bevel gear 10, and the bottom surface of the second bevel gear 10 is meshed with the first bevel gear 9.

[0023] Among them, the thread directions at both ends of the outer surfaces of the first threaded rod 8 and the second threaded rod 81 are opposite. By setting the thread directions at both ends of the first threaded rod 8 and the second threaded rod 81 to be opposite, the two groups of positioning blocks 3 can be driven to move to the opposite or opposite ends. The two groups of positioning blocks 2 are respectively arranged on the outer surfaces of the first threaded rod 8 and the second threaded rod 81 and are threadedly connected to them.

[0024] During operation, the servo motor 4 is first started. When the output shaft of the servo motor 4 rotates, the driving sprocket 5 fixed on the output shaft of the servo motor 4 is driven to rotate. During the rotation of the driving sprocket 5, the driven sprocket 7 is driven to rotate through the transmission chain 6 arranged on the outer surface of the driving sprocket 5. During the rotation of the driven sprocket 7, the first threaded rod 8 fixed in the driven sprocket 7 is driven to rotate. During the rotation of the first threaded rod 8, the first bevel gear 9 fixed on the outer surface of the first threaded rod 8 is driven to rotate. During the rotation of the first bevel gear 9, the second bevel gear 10 meshing therewith is driven to rotate. During the rotation of the second bevel gear 10, the second bevel gear 10 drives the second threaded rod 81 to rotate, so as to achieve the purpose of rotating the first threaded rod 8 and the second threaded rod 81 at the same time. During the rotation of the first threaded rod 8 and the second threaded rod 81, the two positioning blocks 2 respectively arranged on their outer surfaces are driven to move to the opposite end. When moving, the positioning clamp 3 is driven to clamp and position the volleyball.

[0025] See also Figure 3 In order to prevent the volleyball from being damaged due to excessive clamping force, the buffer assembly in this embodiment includes a sleeve 11 fixed between the four positioning blocks 2, a sleeve rod 12 is sleeved in the sleeve 11, and the buffer assembly also includes a spring 13 fixed between the four positioning blocks 2.

[0026] The four springs 13 are respectively sleeved with the four sleeves 11 and the sleeve rods 12 , and opposite ends of the four springs 13 are respectively fixed to opposite ends of the four positioning clamps 3 .

[0027] During operation, the four positioning clamps 3 move toward the opposite end and position the volleyball. When the four sides of the volleyball contact the positioning clamps 3, the sleeve rod 12 arranged on the positioning clamps 3 will shrink into the sleeve 11. At the same time, the positioning clamps 3 will squeeze the spring 13, so that the spring 13 is compressed and stores energy. When the positioning block 2 moves to a suitable position, the elastic action of the spring 13 clamps and positions the volleyball, thereby avoiding the problem of damage to the volleyball due to excessive clamping force.
