Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of box body processing equipment, specifically a box body processing positioning device. Background Technology
[0002] A receiver is a container or shell used to install internal components and some operating structures, such as a gun receiver or magazine. When processing a receiver, it is necessary to first position the receiver before it can be easily machined. However, since different receivers have different shapes and structures, traditional positioning fixtures are difficult to meet the positioning requirements. Simply clamping and positioning the receiver alone will lead to unstable positioning during processing, affecting the processing accuracy and failing to meet the design requirements. Therefore, there is an urgent need for a device that can stably position a specific receiver. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides the following technical solution: a casing processing and positioning device, comprising a casing body and a mounting base. The casing body has a first feature portion on one side of its left front end, a second feature portion on its top side, and a third feature portion on its right end. The inner wall of the third feature portion is provided with a sliding groove. A left support plate and a right support plate are respectively fixedly installed on the top sides of the left and right ends of the mounting base. A left-end positioning component for positioning the left end of the casing body is provided on the right side of the left support plate, and a right-end positioning component for positioning the right end of the casing body is provided on the left side of the right support plate. A compression positioning component for further positioning and limiting the casing body is provided at the end of the left-end positioning component and above the casing body.
[0004] As an optimization, the left-end positioning component includes a fixed plate fixedly installed on the right side of the left support plate, a sliding plate slidably connected between the two fixed plates, a pull rod fixedly installed through the left support plate at the center of the left side of the sliding plate, a compression spring fixedly installed between the sliding plate and the left support plate, and a limiting groove for the first feature to enter is opened inside the fixed plate located in front. By sliding the first feature into the right end of the limiting groove, the limiting function can be achieved.
[0005] As an optimization, the limiting groove is L-shaped, with a vertical part and a horizontal part, and the bottom wall of the horizontal part is provided with an arc-shaped slide corresponding to the bottom of the box body.
[0006] As an optimization, the right-end positioning component includes a first support, a second support, and a limiting post fixedly installed on the left side of the right support plate. The limiting post is located between the first support and the second support. A plug rod is inserted through the center of the first support, the second support, and the limiting post. The plug rod is inserted through the third feature portion. By inserting the plug rod along the first support through the third feature portion and finally into the second support, the body of the box can be limited.
[0007] As an optimization, the end of the insertion rod has a threaded portion, and the threaded portion is screwed into the second support. By screwing the insertion rod into the second support, the insertion rod can be tightened and fixed in place.
[0008] As an optimization, a limiting block is fixedly installed on the outer side of the limiting post, and the limiting block is correspondingly slidably inserted into the slide groove. By inserting the limiting block into the slide groove, the rotation of the box body is further restricted from the inside.
[0009] As an optimization, the extrusion positioning assembly includes a pad and a pressure plate, and the pad has a groove corresponding to the second feature at its center. A screw is rotatably connected to the end of the pressure plate, and a washer is sleeved on the outer side of the end of the screw located above the pressure plate. A threaded hole is opened at the end of the fixing plate located at the rear, and the screw is screwed into the threaded hole. By pressing the pressure plate tightly against the top side of the pad, the box body can be further extruded and positioned.
[0010] The beneficial effects of this utility model are as follows: This box body processing and positioning device can position the left end of the box body by limiting the first feature part through the limiting groove at the left end positioning component, and then position and limit the right end of the box body through the right end positioning component. By positioning from both ends simultaneously, a stable positioning effect can be achieved, preventing the box body from deviating and shifting during processing, thus affecting the processing accuracy. By aligning the pad with the second feature part and pressing it down, the pad is fitted onto the outside of the second feature part. Then, by turning the screw inside the threaded hole, the pressure plate is pressed tightly against the top side of the pad, thereby further squeezing and positioning the box body, further improving the stable positioning effect.

[0018] 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.
[0019] Please see Figure 1-2 A box body processing and positioning device includes a box body 100 and a mounting base 1. The left end of the box body 100 has a first feature 101 on one side of the front, the top side of the box body 100 has a second feature 102, and the right end of the box body 100 has a third feature 103. The inner wall of the third feature 103 is provided with a sliding groove 104. The left and right ends of the mounting base 1 are respectively fixedly mounted with a left support plate 2 and a right support plate 3. The right side of the left support plate 2 is provided with a left end positioning component 4 for positioning the left end of the box body 100, and the left side of the right support plate 3 is provided with a right end positioning component for positioning the right end of the box body 100. The end of the left end positioning component 4 and above the box body 100 is provided with a compression positioning component 5 for further positioning and limiting the box body 100.
[0020] Please see Figure 3The left-end positioning component 4 includes a fixed plate 6 fixedly installed on the right side of the left support plate 2. A sliding plate 7 is slidably connected between the two fixed plates 6. A pull rod 8 that passes through the left support plate 2 is fixedly installed at the center of the left side of the sliding plate 7. A compression spring 9 is fixedly installed between the sliding plate 7 and the left support plate 2. The fixed plate 6 located in front has a limiting groove 10 for the first feature part 101 to enter. The limiting groove 10 is "L" shaped and has a vertical part and a horizontal part. The bottom wall of the horizontal part has an arc-shaped slide corresponding to the bottom of the box body 100. By pulling the pull rod 8 to the left, the sliding plate 7 will move to the left side of the limiting groove 10. At this time, the box body 100 can be placed down between the two fixed plates 6, and the first feature part 101 will slide into the limiting groove 10. Then, by releasing the pull rod 8, the sliding plate 7 will push the box body 100 to the right under the action of the compression spring 9. Therefore, the first feature part 101 will slide into the right end of the limiting groove 10, which can play a limiting role.
[0021] Please see Figure 4 The right-end positioning assembly includes a first support 11, a second support 12, and a limiting post 13 fixedly installed on the left side of the right support plate 3. The limiting post 13 is located between the first support 11 and the second support 12. A plug rod 14 is inserted through the center of the first support 11, the second support 12, and the limiting post 13. The end of the plug rod 14 has a threaded part, which is screwed into the second support 12. By screwing the plug rod 14 into the second support 12, the plug rod 14 can be tightly fixed in position, improving its positioning stability. The insertion rod 14 is inserted through the third feature portion 103. By inserting the insertion rod 14 along the first support 11 through the third feature portion 103 and finally into the second support 12, the box body 100 can be limited to prevent it from deviating and shifting during processing, thus affecting the processing accuracy. A limiting block 15 is fixedly installed on the outside of the limiting post 13, and the limiting block 15 is correspondingly slidably inserted into the slide groove 104. By inserting the limiting block 15 into the slide groove 104, the rotation of the box body 100 is further limited from the inside.
[0022] Please see Figure 5 The compression positioning assembly 5 includes a pad 16 and a pressure plate 18. The pad 16 has a groove 17 corresponding to the second feature 102 at its center. A screw 19 is rotatably connected to the end of the pressure plate 18. A washer ring 20 is sleeved on the outer side of the end of the screw 19 above the pressure plate 18. A threaded hole 21 is opened at the end of the fixing plate 6 located at the rear. The screw 19 is screwed into the threaded hole 21. By aligning the pad 16 with the second feature 102 and sleeved on its outer side, and then turning the screw 19 inside the threaded hole 21, the pressure plate 18 can be pressed tightly against the top side of the pad 16, thereby further compressing and positioning the box body 100 and further improving the stable positioning effect.
[0023] When in use, first pull the lever 8 to the left to move the slide plate 7 to the left side of the limiting groove 10. At this time, the box body 100 can be placed down between the two fixing plates 6, and the first feature part 101 will slide into the limiting groove 10. Then, release the lever 8, and the slide plate 7 will push the box body 100 to the right under the action of the compression spring 9. Therefore, the first feature part 101 will slide into the right end of the limiting groove 10 for locking and limiting.
[0024] At the same time, the right end of the box body 100 will abut against the left side of the right support plate 3 under the action of elastic force. At this time, the insertion rod 14 will pass through the third feature part 103 and the limiting post 13 along the first support 11, and then the insertion rod 14 will be twisted so that the end of the insertion rod 14 will be screwed into the second support 12, which can tighten and fix the insertion rod 14, thereby limiting and positioning the box body 100.
[0025] Finally, align the pad 16 with the second feature 102 and place it on its outer side. Then, by turning the screw 19 inside the threaded hole 21, the pressure plate 18 can be pressed tightly against the top side of the pad 16, thereby further squeezing and positioning the box body 100.
[0026] In summary, this box body processing and positioning device can position the left end of the box body 100 by limiting the first feature part 101 with the four limiting grooves 10 at the left end positioning component, and then position and limit the right end of the box body 100 by the right end positioning component. By positioning from both ends at the same time, it can achieve a stable positioning effect and prevent the box body from deviating and shifting during processing, thus affecting the processing accuracy.
[0027] By aligning the pad 16 with the second feature 102 and pressing it down, the pad 16 is fitted onto the outside of the second feature 102. Then, by turning the screw 19 inside the threaded hole 21, the pressure plate 18 is pressed tightly against the top side of the pad 16, thereby further squeezing and positioning the box body 100 and further improving the stable positioning effect.
