Detailed Implementation

[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] Example: Please refer to Figures 1 to 6. According to an embodiment of this utility model, an anti-deformation device for processing a thin-walled slotted connector housing is provided, which can reduce the probability of deformation of the connector housing 100 during polishing. The anti-deformation device includes a main body 200, an adjusting screw 300, and multiple support members 400. The main body 200 has a base plate 210 and a side plate 220 vertically fixed to the base plate 210. The adjusting screw 300 is rotatably connected to the side plate 220, and the adjusting screw 300 is provided with two external threads 310 arranged along its own axial direction with opposite directions. A movable nut 320 is threadedly connected to the external threads 310. Multiple support members 400 are arranged circumferentially around the adjusting screw 300. The multiple support members 400 are slidably connected to the side plate 220 along the radial direction of the adjusting screw 300, and the inner side of each support member 400 is hinged to the movable nut 320 through a connecting rod 330. Specifically, in this embodiment, the connecting rod 330 and the movable nut 320, as well as the connecting rod 330 and the support member 400, are rotatably connected by a rotating shaft 340.

[0028] The anti-deformation device for the thin-walled slotted connector housing with the above-described structure works by rotating the adjusting screw 300 during use to bring the two moving nuts 320 as close as possible, causing multiple support members 400 to move closer to the adjusting screw 300. Then, the connector housing 100 to be polished is placed on the support members 400, and the adjusting screw 300 is rotated in the opposite direction to separate the two moving nuts 320. This causes the support members 400 to expand outwards radially along the adjusting screw 300 until they are tightly against the inner wall of the connector housing 100, providing support for the inner wall. Polishing the outer surface of the connector housing 100 at this point effectively reduces the probability of deformation and minimizes the possibility of deformation during polishing, ensuring the product's appearance quality.

[0029] In this exemplary embodiment, as shown in Figures 3 and 4, a slider 430 is fixedly mounted on the support member 400, and a groove 221 suitable for sliding engagement with the slider 430 is provided on the side plate 220. Specifically, in this embodiment, the slider 430 is a rod-shaped structure with different diameters at both ends. The small end of the slider 430 is fixedly connected to the side plate 220, and the large end of the slider 430 is a free end. A columnar connecting platform 222 protrudes from one side of the side plate 220, and the groove 221 is provided on the connecting platform 222. The groove 221 has a notch formed on the end face of the connecting groove, and the width of the notch is the same as the diameter of the small end of the slider 430. An assembly opening is formed on the edge of the connecting groove, and the large end of the slider 430 can be inserted into the groove 221 through the assembly opening. It can be understood that the support member 400 can slide smoothly along the radial direction of the adjusting screw 300 through the engagement of the slider 430 and the groove 221. The assembly opening is provided to facilitate the insertion of the slider 430 into the groove 221.

[0030] In this exemplary embodiment, as shown in FIG4, the support member 400 has an arc-shaped plate structure, and the diameter of the circle containing the outer arc surface of the support member 400 is the same as the diameter of the circle containing the inner arc surface of the connector housing 100. This can maximize the contact surface between the support member 400 and the connector housing 100, thereby reducing the probability of the support member 400 crushing and damaging the inner wall of the connector housing 100.

[0031] In this exemplary embodiment, as shown in Figures 5 and 6, the anti-deformation device for the thin-walled slotted connector housing 100 includes two sets of support members 400. The diameters of the outer arc surfaces of the two sets of support members 400 are different, and the two sets of support members 400 are detachably connected. In this way, the inner walls of connector housings 100 with different inner diameters can be supported by the two sets of support members 400 with different diameters of their outer arc surfaces, improving the applicability of the anti-deformation device. In other embodiments, the number of support members 400 can be set according to actual needs, for example, more than two sets, with the diameters of the outer arc surfaces of adjacent sets of support members 400 being different.

[0032] In this exemplary embodiment, as shown in FIG6, the two sets of support members 400 consist of a plurality of first support members 410 and a plurality of second support members 420. The diameter of the circle containing the outer arc surface of the first support member 410 is smaller than the diameter of the circle containing the outer arc surface of the second support member 420. The first support members 410 and the second support members 420 are fixed together by magnetic attraction. Specifically, in this embodiment, a magnetic block 440 is embedded and fixedly disposed on the outer side of the first support member 410, and the second support member 420 is made of magnetic material. It can be understood that fixing the two sets of support members 400 together by magnetic attraction facilitates the assembly and disassembly of the two sets of support members 400. In other embodiments, the two sets of support members 400 can also be connected by snap-fit ​​or bolt connection.

[0033] In this exemplary embodiment, as shown in FIG6, a positioning pin 450 is provided on the inner side of the second support member 420, and a positioning hole 460 suitable for positioning and engaging with the positioning pin 450 is provided on the outer side of the first support member 410. Specifically, in this embodiment, the positioning pin 450 is cylindrical and there are two of them; correspondingly, there are also two positioning holes 460. It can be understood that the engagement of the positioning pin 450 and the positioning hole 460 allows for a tighter connection between the first support member 410 and the second support member 420. In other embodiments, the positioning pin 450 can also be provided on the outer side of the first support member 410, and the positioning hole 460 can be provided on the inner side of the second support member 420. The positioning pin 450 can also be a polygonal prism, and correspondingly, the positioning hole 460 is polygonal. When the positioning pin 450 is a polygonal prism, the number of positioning pins 450 can be only one.

[0034] In this exemplary embodiment, as shown in FIG4, an adjusting screw 300 is disposed through the side plate 220. Two external threads 310 with opposite directions of rotation are disposed at one end of the adjusting screw 300, and a knob 340 is fixedly disposed at the other end of the adjusting screw 300. The outer side of the knob 340 is provided with anti-slip texture. The operator can drive the adjusting screw 300 to rotate by squeezing the knob 340 with his hand, which is more labor-saving, and the anti-slip texture can also increase friction and reduce the phenomenon of hand slippage. In other embodiments, the knob 340 can be replaced by a motor. The housing of the motor is fixed on the side plate 220, and the output shaft of the motor is fixedly connected to the end of the adjusting screw 300 by a coupling. This can replace manual driving of the adjusting screw 300 to rotate, making it more convenient to use.

[0035] In this exemplary embodiment, as shown in Figures 2, 3, and 5, a collection trough 500 is placed on a base plate 210 located below the plurality of supports 400, with the opening of the collection trough 500 facing upwards. By providing the collection trough 500, waste shavings generated during the grinding of the connector can be collected, ensuring a clean processing environment and facilitating subsequent processing of the waste shavings.

[0036] In this exemplary embodiment, as shown in FIG3, the bottom sides of the collection tank 500 extend downward to form protruding edges 510 arranged along their width direction. The distance between the two protruding edges 510 is equal to the width of the base plate 210. The end of the base plate 210 away from the side plate 220 extends upward to form a boss 211. The distance between the boss 211 and the side plate 220 is equal to the length of the collection tank 500. By setting the protruding edges 510, the collection tank 500 can be restricted to move in the left and right direction on the base plate 210. By cooperating with the side plate 220, the collection tank 500 can be restricted to move in the front and back direction on the base plate 210, thereby restricting the horizontal movement of the collection tank 500 and ensuring that the collection tank 500 can be stably placed on the base plate 210. It also makes it convenient to remove the collection tank 500 from the base.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
