Description

Technical Field

[0001] This utility model relates to the field of positioning structure technology, specifically a steel ball positioning structure. Background Technology

[0002] The steel ball positioning structure achieves high-precision, low-friction positioning or fixing functions through the rolling or snapping characteristics of steel balls, and is widely used in precision machinery, automated equipment and high-end manufacturing fields.

[0003] In quick-clamping tools, ball spring positioning structures are often used to fix parts. The spring presses the ball into the positioning hole of the mating part to achieve fixation or positioning. However, in ball spring positioning structures, the steel column and spring are usually set inside the outer shell. After long-term use, the outer shell is prone to damage, the ball wears out significantly, the spring elasticity decreases, or the spring breaks. When these situations occur, it is impossible to disassemble the ball spring positioning structure for targeted repair, and often a new ball spring positioning structure is replaced, resulting in waste. Therefore, it is necessary to provide a ball spring positioning structure to solve the above problems. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-7 A steel ball positioning structure includes a mounting frame 1, which has a threaded hole. The upper end of the mounting frame 1 is threadedly connected to a housing 2 through the threaded hole. An elastic positioning component 5 is provided inside the housing 2.

[0028] The outer shell 2 includes a first half-screw shell 201 and a second half-screw shell 202. The first half-screw shell 201 and the second half-screw shell 202 are provided with a slot 203 on the upper end of the side close to each other. The upper end of the outer shell 2 is provided with a fixing component 3 for fixing the first half-screw shell 201 and the second half-screw shell 202.

[0029] The fixing component 3 includes a post 302, which is inserted into the slot 203.

[0030] The elastic positioning component 5 includes a spring 501, a top circular plate 502, a limiting base 503, and a steel ball 504. The upper end of the spring 501 is connected to the top circular plate 502, and the lower end of the spring 501 is connected to the limiting base 503. The steel ball 504 is rotatably mounted on the lower end of the limiting base 503. The lower end of the steel ball 504 passes through the lower opening of the outer shell 2 and extends to the outside. When the steel ball 504 is compressed, it will push the spring 501 to contract through the limiting base 503, and then the steel ball 504 can retract into the interior of the outer shell 2. When the steel ball 504 loses pressure, the spring 501 presses the steel ball 504 into the positioning hole of the mating part to achieve positioning.

[0031] The fixing component 3 further includes a first vertical plate frame 301, a second vertical plate frame 303, and a positioning pin 304. Two first vertical plate frames 301 are provided, respectively fixed to the upper surfaces of the first semi-screw shell 201 and the second semi-screw shell 202. The second vertical plate frame 303 is located on the upper surface of the insert post 302. Both the first and second vertical plate frames 301 and 303 have through holes. The front end of the outer surface of the positioning pin 304 has a first external thread. The front end of the positioning pin 304 passes through the through hole and through the first external thread. The external threaded connection is secured with a fastening nut 305. After the first half-shell 201 and the second half-shell 202 are aligned and the elastic positioning component 5 is placed inside, the insert post 302 is inserted into the slot 203, and then the front end of the positioning pin 304 is passed through the through hole at the upper end of the first vertical plate frame 301 and the second vertical plate frame 303. Finally, the fastening nut 305 is tightened, thereby achieving a tight connection between the first half-shell 201 and the second half-shell 202. The whole assembly is convenient, and when a certain part is damaged, it can be replaced at any time to avoid waste.

[0032] Among them, the lower end of the outer surface of the first half-shell 201 and the second half-shell 202 are provided with the second external thread 6. The lower end of the first half-shell 201 and the second half-shell 202 are threadedly connected to the limiting bottom ring 7 through the second external thread 6. By rotating the limiting bottom ring 7, the limiting bottom ring 7 can be effectively fitted onto the lower end of the outer surface of the outer shell 2, further ensuring the stability between the first half-shell 201 and the second half-shell 202.

[0033] The first and second half-shells 201 and the second half-shell 202 are both provided with handles 4 on their upper outer surfaces. The mounting bracket 1 is provided with a base plate 101 at its lower end. The base plate 101 is provided with fixing holes 102. The handles 4 make it easy for the operator to rotate the outer shell 2 and move it up and down by turning the handles 4. The base plate 101 and fixing holes 102 make it easy to install and fix the mounting bracket 1 and ensure the stability of the mounting bracket 1.

[0034] Working principle: The outer shell 2 includes a first half-screw shell 201 and a second half-screw shell 202. When the first half-screw shell 201 and the second half-screw shell 202 are aligned and the elastic positioning component 5 is placed inside, the insert post 302 is inserted into the slot 203, and then the front end of the positioning pin 304 passes through the through hole at the upper end of the first vertical plate frame 301 and the second vertical plate frame 303. Finally, the fastening nut 305 is tightened, thereby achieving a tight connection between the first half-screw shell 201 and the second half-screw shell 202. By rotating the limiting bottom ring 7, the limiting bottom ring 7 can be effectively fitted onto the lower end of the outer surface of the outer shell 2, further ensuring the stability between the first half-screw shell 201 and the second half-screw shell 202. The whole assembly is convenient, and when a certain part is damaged, it can be replaced at any time to avoid waste.

[0035] Furthermore, by providing a handle 4, the operator can easily rotate the outer casing 2 and move it up and down by turning the handle 4 to effectively adjust its position; when the steel ball 504 is compressed, it will push the spring 501 to contract through the limiting base 503, and then the steel ball 504 can retract into the inner casing 2. When the steel ball 504 loses pressure, the spring 501 presses the steel ball 504 into the positioning hole of the mating part to achieve positioning; by providing a base plate 101 and a fixing hole 102, it is easy to install and fix the mounting bracket 1 to ensure the stability of the mounting bracket 1.
