[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example
[0029] A valve ball grinding and positioning device with an anti-displacement structure includes a positioning frame 1. A controller is located on the right side of the positioning frame 1. A back frame 2 for mounting and fixing grinding tools is fixed to the back of the top of the positioning frame 1. Square columns 5 are inserted into the top of both sides of the positioning frame 1. A reinforcing shaft 7 is rotatably installed in each set of square columns 5. A fixing cone 10 for inserting into the inner cavity of the valve ball is fixed to one end of the reinforcing shaft 7 that is close to each other. An anti-displacement component is provided on the positioning frame 1 to cooperate with the fixing cone 10 and to position the valve ball. The anti-displacement component includes an electric slide rail 3 that is fixed to the back of the positioning frame 1 by a fixing frame and has a built-in positive and negative threaded rod. An L-shaped docking frame 4, one end of which is fixed to the square column 5, is fixed in the electric slide rail 3 by symmetrically arranged slides. The fixed cones 10 have grooves 11 on their adjacent sides. Rotating shafts 14 are rotatably mounted on the outer sides of the front and back of the inner cavity of the grooves 11. Gears 16 and abutment plates 15 are fixed sequentially from the inside to the outside on each set of rotating shafts 14. Strip holes 19 are opened on the back of the top and the front of the bottom of the inner cavity of each set of reinforcing shafts 7. Push pins 17 are inserted into each set of strip holes 19. Placement slots 22 are opened on the inner sides of the upper and lower sets of push pins 17 that are close to each other. Multiple sets of teeth 18 that mesh with gears 16 are fixed sequentially in the left and right direction in the placement slots 22. Electric push rods 12 are fixed to the opposite ends of the reinforcing shafts 7 through a mounting bracket. The piston rod of the electric push rod 12 is fixed to a vertical plate 13, and one end of each of the two adjacent sets of push pins 17 is fixed to the vertical plate 13.
[0030] Specifically, by setting an anti-detachment component, the electric slide rail 3 provides a driving source, which can drive two sets of fixed cones 10 to move synchronously and squeeze and position the side of the valve ball according to its size. The design of the electric push rod 12, in conjunction with the teeth 18 and gears 16, can change the angle of the abutment plate 15 to squeeze and position the inside of the valve ball. The multi-directional and multi-means positioning method improves the positioning stability of the valve ball by the positioning device, effectively avoids the valve ball from easily shifting during the grinding process, and improves the grinding effect on the surface of the valve ball.
[0031] A motor 8 is fixed to the right side of the top of the right square column 5. A synchronous pulley 9 driven by a synchronous belt is fixed to the end of the output shaft of the motor 8 and the right side reinforcing shaft 7.
[0032] Specifically, the design of the motor 8 and the synchronous pulley 9, together with the synchronous belt, can drive the reinforcing shaft 7 to rotate, thereby driving the positioned valve ball to rotate synchronously, so as to uniformly polish the surface of the valve ball, improve polishing efficiency, and the design of the synchronous pulley 9 and the synchronous belt can effectively prevent slippage.
[0033] The top of both sides of the positioning frame 1 is fixed with U-shaped frames 6 that are snapped into the bottom of the square column 5.
[0034] Specifically, the design of the U-shaped frame 6 facilitates sliding support at the bottom of the square column 5, improving the stability of the square column 5 when it moves and preventing one end from easily sagging, which would affect the stability of the square column 5 when it moves.
[0035] The inner sides of the upper and lower push columns 17 that are close to each other are fixed with locking seats 20. The side of the locking seat 20 away from the push column 17 is locked with a strip slide plate 21. The side of the strip slide plate 21 away from the locking seat 20 is fixed in the groove 11.
[0036] Specifically, by utilizing the mutual sliding of the locking seat 20 and the strip slide plate 21, the direction of movement of one end of the push post 17 can be limited, preventing the one end of the push post 17 from deviating during movement, thus affecting the normal meshing of the teeth 18 and the gear 16, and also preventing any impact on the normal drive of the abutment plate 15.
[0037] There is a gap on the side where two adjacent sets of gears 16 are close to each other.
[0038] Specifically, the spacing design can effectively prevent the gears 16 from rubbing against each other and interfering with each other during transfer, thus avoiding affecting the normal operation of the gears 16 and the stability of the device during operation.
[0039] Each set of 15 support plates has an L-shaped structure.
[0040] Specifically, the L-shaped design of the abutment plate 15 provides sufficient installation space for the gears 16, avoids friction between adjacent sets of gears 16, and prevents the abutment plate 15 from contacting and colliding with the gears 16 when rotating, thus improving the stability of the abutment plate 15 when rotating.The specific usage process is as follows: The user installs the grinding tool on the back frame 2 and places the valve ball to be ground between the two sets of fixed cones 10. At this time, the user activates the electric slide rail 3 through the controller and uses its built-in positive and negative threaded rods to drive the two sets of slides on it to move in opposite directions, thereby driving the two sets of L-shaped docking frames 4 to move in opposite directions, thereby pushing the two sets of square columns 5 to move inward, so that the fixed cones 10 can be inserted into the hole of the valve ball. As the fixed cones 10 continue to move, they squeeze and position the two sides of the valve ball. At this time, the electric push rod 12 is activated through the controller, which drives the vertical plate 13 to move outward, thereby driving the two sets of push columns 17 to move synchronously. Since the push columns 17 are symmetrically arranged vertically and staggered, and the teeth 18 are located on the push columns 17 The two sets of pushers 17 move close to each other, thus driving the two sets of gears 16 to rotate synchronously in opposite directions. This causes the two adjacent sets of abutments 15 to swing synchronously in opposite directions, further squeezing and positioning the inside of the valve ball. This multi-directional and multi-method positioning method improves the positioning stability of the valve ball and effectively prevents the valve ball from easily shifting during grinding. At this time, the user can start the motor 8 via the controller, and with the transmission of the synchronous pulley 9 and synchronous belt, the reinforcing shaft 7 and the valve ball on it can rotate synchronously, facilitating uniform grinding of the valve ball surface by the grinding tools. By setting an anti-detachment component, the electric slide rail 3 provides the driving source, driving the two sets of fixed cones 10 to move synchronously and squeezing and positioning the sides of the valve ball according to its size. The electric push rod 12, along with teeth 18 and gears 16, can change the angle of the abutment plate 15 to press and position the valve ball internally. This multi-directional and multi-method positioning improves the positioning stability of the valve ball and effectively prevents it from shifting during grinding, thus improving the grinding effect on the valve ball surface. The design of the motor 8 and synchronous pulley 9, along with the synchronous belt, drives the reinforcing shaft 7 to rotate, thereby driving the positioned valve ball to rotate synchronously, ensuring uniform grinding of the valve ball surface and improving grinding efficiency. The synchronous pulley 9 and synchronous belt design effectively prevent slippage. The U-shaped frame 6 facilitates sliding support at the bottom of the square column 5, improving the stability of the square column 5 during movement. To prevent one end from sagging and affecting the stability of the square column 5 during movement, the sliding of the locking seat 20 and the strip slide plate 21 can limit the direction of movement of one end of the push column 17, preventing the push column 17 from deviating during movement and affecting the normal meshing of the teeth 18 and gear 16, and also preventing it from affecting the normal drive of the abutment plate 15. The spacing design can effectively prevent the gears 16 from rubbing against each other and interfering with each other during transfer, affecting the normal operation of the gears 16 and the stability of the device during operation. The L-shaped design of the abutment plate 15 can provide sufficient installation space for the gears 16, preventing adjacent sets of gears 16 from rubbing against each other, and at the same time preventing the abutment plate 15 from contacting and colliding with the gears 16 when rotating, thus improving the stability of the abutment plate 15 during rotation.
[0041] Therefore, by setting up an anti-detachment component, the valve ball can be autonomously positioned in multiple directions on both sides and inside according to its size. At this time, the multi-directional and multi-method positioning method improves the positioning stability of the valve ball by the positioning device, effectively preventing the valve ball from shifting during the grinding process, and greatly improving the grinding effect and accuracy of the grinding tool on the surface of the valve ball.
[0042] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
