Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of basketball hoop processing equipment, and in particular to a positioning fixture for basketball hoop processing. Background Technology
[0002] During the production and processing of basketball hoops, various components (such as the backboard mounting frame, uprights, and base connectors) need to be cut, welded, and drilled. Because the backboard mounting frame is mostly made of metal and is relatively large, positioning clamps are needed to secure it during these processes.
[0003] In the existing technology, the positioning devices for backboard mounting frame processing are mostly general-purpose clamps. However, general-purpose clamps have poor flexibility and are inconvenient to use, which seriously affects the processing efficiency of backboard mounting frames. Furthermore, the size of general-purpose clamps cannot be adjusted, which cannot meet the processing needs of backboard mounting frames of different sizes, and their practicality is not high.
[0004] To address the aforementioned technical deficiencies, a solution is proposed: the backboard mounting frame is placed outside the first and second support bars, and a crank handle is used to drive the double-acting screw to rotate. Under the influence of the double-acting screw, the first and second screw nuts will move away from each other, and the first and second support bars will also move away from each other. Once the first and second support bars abut against the inner wall of the backboard mounting frame, the backboard mounting frame can be fixed. The overall flexibility is good, and fixing the backboard mounting frame is relatively simple and convenient. Utility Model Content
[0005] The purpose of this invention is to provide a positioning fixture for processing basketball hoops to solve the problems mentioned above.
[0006] The objective of this utility model can be achieved through the following technical solution: a positioning fixture for processing basketball hoops, comprising: The clamping assembly includes a base, a connecting plate fixed to the top of the base, a first support plate and a second support plate correspondingly fixed to the outer wall of the connecting plate, a first bearing and a second bearing correspondingly installed inside the first support plate and the second support plate, a bidirectional lead screw fixed inside the first bearing and the second bearing, a crank fixed to one end of the bidirectional lead screw, a first lead screw nut and a second lead screw nut correspondingly threaded onto the outer wall of the bidirectional lead screw, and a first support bar and a second support bar correspondingly fixed to the outer wall of the first lead screw nut and the second lead screw nut.
[0007] Preferably, the first lead screw nut and the second lead screw nut are threadedly installed in different thread regions of the bidirectional lead screw.
[0008] Preferably, it also includes a limiting component, which includes a limiting groove formed on the outer wall of the connecting plate and two sets of limiting strips correspondingly and movably disposed in the limiting groove.
[0009] Preferably, the two sets of limiting strips are fixed to the first lead screw nut and the second lead screw nut respectively.
[0010] Preferably, both sets of limiting strips have positioning holes at their bottoms, a connecting block is fixed to the outer wall of the connecting plate, a movable plate is movably arranged inside the connecting block, two sets of first through holes are correspondingly opened at the top of the connecting block, two sets of positioning rods are correspondingly fixed at the top of the movable plate, and the two sets of positioning rods pass through the two sets of first through holes and are correspondingly engaged inside the two sets of positioning holes.
[0011] Preferably, the bottom of the connecting block is provided with two sets of second through holes, and the bottom of the movable plate is provided with two sets of connecting rods passing through the two sets of second through holes, and a foot pedal is fixed to one end of each of the two sets of connecting rods.
[0012] Preferably, both sets of connecting rods are provided with springs on their exterior, and the two ends of the two sets of springs are fixed to the bottom of the movable plate and the bottom of the connecting block, respectively.
[0013] The beneficial effects of this utility model are: 1. Place the backboard mounting frame outside the first and second support bars, then use a crank to drive the double-acting screw to rotate. Under the drive of the double-acting screw, the first and second screw nuts will move away from each other, and the first and second support bars will also move away from each other. When the first and second support bars abut against the inner wall of the backboard mounting frame, the backboard mounting frame can be fixed. Compared with the existing ones, this utility model has better flexibility and is simpler and more convenient to fix the backboard mounting frame, thereby improving the processing efficiency of the backboard mounting frame. Furthermore, since the first and second support bars can move towards each other or away from each other, the distance between the first and second support bars is adjustable, making the first and second support bars suitable for fixing backboard mounting frames of different sizes, resulting in high overall practicality.
[0014] 2. Since the two sets of limiting strips are movably set inside the limiting groove, and the two sets of limiting strips are fixed to the first screw nut and the second screw nut respectively, the movement path of the first screw nut and the second screw nut can be limited by the cooperation of the two sets of limiting strips and the limiting groove, so as to avoid the angle of the first screw nut and the second screw nut from shifting, thereby ensuring the fixing effect of the first support strip and the second support strip on the backboard mounting frame; Under the action of the two sets of springs, the two sets of connecting rods will be driven to rise in the two sets of second through holes. Similarly, the movable plate will also rise inside the connecting block, and the two sets of positioning rods will also rise in the two sets of first through holes. When the tops of the two sets of positioning rods are engaged in the two sets of positioning holes, the two sets of limiting strips can be fixed, which indirectly achieves the purpose of fixing the first screw nut and the second screw nut, further ensuring the fixing effect of the first support and the second support on the backboard mounting frame.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1: The application background of this utility model is based on the fact that in the existing technology, the positioning devices for backboard mounting frame processing are mostly general-purpose clamps. However, general-purpose clamps have poor flexibility, are inconvenient to use, and seriously affect the processing efficiency of backboard mounting frames. Furthermore, the size of general-purpose clamps cannot be adjusted, which cannot meet the processing needs of backboard mounting frames of different sizes, and their practicality is not high. The technical solution of this utility model is to solve the problem of how to improve the flexibility of general-purpose clamps and make them adjustable. Please see Figures 1-2 As shown, this embodiment is a positioning fixture for processing basketball hoops, including: a fixture assembly 100, including a base 101, a connecting plate 102 fixed to the top of the base 101, a first support plate 103 and a second support plate 104 correspondingly fixed to the outer wall of the connecting plate 102, a first bearing 105 and a second bearing 106 correspondingly installed inside the first support plate 103 and the second support plate 104, a bidirectional lead screw 107 fixed inside the first bearing 105 and the second bearing 106, a crank handle 108 fixed to one end of the bidirectional lead screw 107, a first lead screw nut 109 and a second lead screw nut 110 correspondingly threaded on the outer wall of the bidirectional lead screw 107, a first support bar 111 and a second support bar 112 correspondingly fixed to the outer wall of the first lead screw nut 109 and the second lead screw nut 110, and the first lead screw nut 109 and the second lead screw nut 110 correspondingly threaded on different thread areas of the bidirectional lead screw 107; The backboard mounting frame is placed outside the first support bar 111 and the second support bar 112. The crank handle 108 drives the double-acting screw 107 to rotate. Driven by the double-acting screw 107, the first screw nut 109 and the second screw nut 110 move away from each other, and the first support bar 111 and the second support bar 112 also move away from each other. Once the first support bar 111 and the second support bar 112 abut against the inner wall of the backboard mounting frame, the backboard mounting frame can be fixed. Compared to existing designs, this invention offers better flexibility and is simpler and more convenient to fix the backboard mounting frame, thus improving the processing efficiency. Furthermore, since the first support bar 111 and the second support bar 112 can move towards each other or away from each other, the distance between them is adjustable, making them suitable for fixing backboard mounting frames of different sizes, resulting in high overall practicality.
[0019] Example 2: Please refer to Figures 1-4As shown, this embodiment is a positioning fixture for processing basketball hoops, and also includes a limiting component 200. The limiting component 200 includes a limiting groove 201 formed on the outer wall of the connecting plate 102, and two sets of limiting strips 202 correspondingly and movably disposed in the limiting groove 201. The two sets of limiting strips 202 are fixed to the first lead screw nut 109 and the second lead screw nut 110 respectively. The bottom of each set of limiting strips 202 is provided with a positioning hole 203. A connecting block 204 is fixed on the outer wall of the connecting plate 102. A movable plate 205 is movably disposed inside the connecting block 204. The top of the connecting block 204 is provided with two sets of first through holes. Hole 206, two sets of positioning rods 207 are fixed to the top of movable plate 205, the two sets of positioning rods 207 pass through two sets of first through holes 206 and are correspondingly engaged in the interior of two sets of positioning holes 203, two sets of second through holes 208 are correspondingly opened at the bottom of connecting block 204, two sets of connecting rods 209 are fixed to the bottom of movable plate 205, passing through two sets of second through holes 208, a foot plate 210 is fixed to one end of the two sets of connecting rods 209, and springs 211 are provided on the outside of the two sets of connecting rods 209, and the two ends of the two sets of springs 211 are correspondingly fixed to the bottom of movable plate 205 and the bottom of inner connection block 204; Since the two sets of limiting strips 202 are movably set inside the limiting groove 201, and the two sets of limiting strips 202 are fixed to the first lead screw nut 109 and the second lead screw nut 110 respectively, the movement path of the first lead screw nut 109 and the second lead screw nut 110 can be limited by the cooperation of the two sets of limiting strips 202 and the limiting groove 201, so as to avoid the angle of the first lead screw nut 109 and the second lead screw nut 110 from shifting, thereby ensuring the fixing effect of the first support strip 111 and the second support strip 112 on the backboard mounting frame; Under the action of the two sets of springs 211, the two sets of connecting rods 209 will be driven to rise within the two sets of second through holes 208. Similarly, the movable plate 205 will also rise within the connecting block 204, and the two sets of positioning rods 207 will also rise within the two sets of first through holes 206. When the tops of the two sets of positioning rods 207 are engaged with the two sets of positioning holes 203, the two sets of limiting strips 202 can be fixed, thereby indirectly achieving the purpose of fixing the first lead screw nut 109 and the second lead screw nut 110, further ensuring the fixing effect of the first support strip 111 and the second support strip 112 on the backboard mounting frame.
[0020] In summary, please refer to the following: Figures 1-4Before fixing the backboard mounting frame, the worker steps on the foot pedal 210. The foot pedal 210 drives the two sets of connecting rods 209 to descend within the two sets of second through holes 208. The movable plate 205 also descends within the connecting block 204, and the two sets of positioning rods 207 descend within the two sets of first through holes 206. This is to prevent the two sets of positioning rods 207 from obstructing the movement of the two sets of limiting strips 202. The worker then places the backboard mounting frame outside the first support bar 111 and the second support bar 112, and uses the crank 108 to drive the double-acting screw 107 to rotate. Driven by the double-acting screw 107, the first screw nut 109 and the second screw nut 110 move away from each other, while the first support bar 111... The second support bar 112 will also move away from each other. When the first support bar 111 and the second support bar 112 abut against the inner wall of the backboard mounting frame, the backboard mounting frame can be fixed. When the staff releases the foot pedal 210, the two sets of springs 211 will drive the two sets of connecting rods 209 to move upward in the two sets of second through holes 208. Similarly, the movable plate 205 will also move upward in the connecting block 204, and the two sets of positioning rods 207 will also move upward in the two sets of first through holes 206. When the tops of the two sets of positioning rods 207 are engaged in the two sets of positioning holes 203, the two sets of limiting bars 202 can be fixed, thereby indirectly achieving the purpose of fixing the first screw nut 109 and the second screw nut 110.
[0021] As can be seen from Embodiments 1 and 2, on the one hand, this utility model has good flexibility and is relatively simple and convenient to fix the backboard mounting frame, thereby improving the processing efficiency of the backboard mounting frame; and since the first support bar 111 and the second support bar 112 can move towards each other or away from each other, the distance between the first support bar 111 and the second support bar 112 is adjustable, making the first support bar 111 and the second support bar 112 suitable for fixing backboard mounting frames of different sizes, with high overall practicality; on the other hand, with the cooperation of the two sets of limiting bars 202 and limiting grooves 201, the first support bar 111 can be used to fix the backboard mounting frame of different sizes. The movement paths of the first lead screw nut 109 and the second lead screw nut 110 are limited to prevent the angles of the first lead screw nut 109 and the second lead screw nut 110 from shifting, thereby ensuring the fixing effect of the first support bar 111 and the second support bar 112 on the backboard mounting frame; and when the tops of the two sets of positioning rods 207 are engaged with the two sets of positioning holes 203, the two sets of limiting bars 202 can be fixed, indirectly achieving the purpose of fixing the first lead screw nut 109 and the second lead screw nut 110, further ensuring the fixing effect of the first support bar 111 and the second support bar 112 on the backboard mounting frame.
[0022] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
