[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] The main purpose of the part fixture in this application is to improve the fixture so that parts with machining structures on both sides can be clamped and fixed at one time, and the machining of the two sides can be performed separately under the condition of clamping and fixing at one time, thereby avoiding the disassembly and assembly operation of separate clamping and machining and improving the machining accuracy.

[0028] Combination Figures 3-5 The part fixture tooling of this utility model is used to clamp part 4 once. The main structure includes a fixture body 1 and a clamping part 2. The fixture body 1 is specifically a fixture seat structure, which is used to fix it on the processing equipment, while the clamping part 2 is mainly used to clamp and fix the double-sided processed part 4.

[0029] The clamping part 2 is provided with a positioning mechanism and a fixing mechanism. The positioning mechanism includes a positioning block 3 for positioning and clamping the corners of the part 4. The part 4 can be quickly positioned and installed on the side wall of the clamping part 2 through the positioning mechanism.

[0030] In this application, in order to facilitate fixing on the clamping part 2, the part 4 includes a pair of through holes 41, which are mainly used for clamping the part 4 on the clamping part 2.

[0031] The through hole 41 is specifically the structure of the part 4 itself, and it can also be a through hole 41 structure specially set up to cooperate with the clamping and fixing on the clamping part 2.

[0032] The fixing mechanism includes a fixing post 5 and a screw 52. The fixing post 5 is connected to the through hole 41 and the part 4 is fastened and clamped by the screw 52.

[0033] When part 4 is clamped and fixed, the fixing post 5 passes through the through hole 41 on part 4, and the screw 52 is threadedly connected to the fixing post 5, so that the screw 52 head exposed on the end of the fixing post 5 is fastened to part 4.

[0034] Combination Figures 1-2 The specific structure of part 4 is defined by the side of the arc-shaped ball table 44, which is the front side of part 4, and the other side including the circular central countersunk hole 42 is the back side. The structures to be processed include the circular central countersunk hole 42 on the back side and the through groove on the arc-shaped ball table 44 on the front side that corresponds to the countersunk hole.

[0035] Based on the structure that needs to be processed as described above, the paired through holes 41 are respectively provided on both sides of the circular central countersunk hole 42 and the arc-shaped ball platform 44, which can fix the part 4 on both sides in the width direction of the part 4.

[0036] In this utility model, part 4 is specifically clamped on one side of the clamping part 2 during positioning and clamping, so that the reverse side of part 4 is attached and fixed to the side wall of the clamping part 2.

[0037] Based on this, the positioning mechanism and the fixing mechanism are arranged on the side wall of the clamping part 2 on the same side. The clamping part 2 includes a vertical plane 21 arranged opposite to each other. The positioning block 3 and the fixing post 5 are arranged on the vertical plane 21. The extension direction of the fixing post 5 is arranged horizontally and perpendicular to the vertical plane 21, so that the reverse side of the part 4 can be attached and fixed on the vertical plane 21.

[0038] A machining clearance groove 6 is provided on the side wall of the clamping part 2. The machining clearance groove 6 is used to machine the circular center countersunk hole 42 and includes a clearance groove opened on the side wall.

[0039] Compared to the aforementioned vertical plane 21, the side wall on the other side of the clamping part 2 specifically includes a beveled plane 22. An anti-cavity recess is formed on the beveled plane 22. The setting of the beveled plane 22 can increase the overall rigidity of the fixture and help ensure machining accuracy.

[0040] In one specific embodiment, the part 4 to be processed includes a square part 4, and the positioning block 3 includes four sets of corner positioning blocks 3 distributed in an L-shape. Each set of corner positioning blocks 3 includes two long strip structures, which are distributed in an L-shape and correspond to each corner of the square part 4, so that the corners of the square part 4 can be positioned and clamped.

[0041] From the perspective of fastening and installing part 4, the through hole 41 on part 4 includes a light hole that runs through the thickness direction of part 4. The light hole is clearance-fitted with the fixing post 5. During the installation process, the reverse side of the square part 4 faces the vertical plane 21 and is quickly positioned and clamped by the positioning block 3, while the fixing post 5 passes through the light hole.

[0042] The fixing post 5 is provided with a threaded channel 51, and the screw 52 is threaded into the threaded channel 51, with the screw head of the screw 52 exposed at the end of the fixing post 5, thus pressing and fixing the part 4.

[0043] To facilitate locking installation, part 4 is provided with a locking groove 43 at the light hole. The locking groove 43 includes an open groove at the edge of part 4. See the attached figure. The locking groove 43 is specifically a side-open groove structure, which is conducive to the screwing operation of screw 52.

[0044] In order to ensure that the screw 52 can lock and fix the part 4, the end face of the fixing post 5 is recessed into the groove surface of the locking groove 43 when the hole and the fixing post 5 are connected, or the end face of the fixing post 5 is flush with the groove surface of the locking groove 43, so as to ensure that the screw head of the screw 52 is exposed on the groove surface of the locking groove 43, thereby achieving the press-fit fixing relationship of the part 4.

[0045] In this embodiment, the threaded channel 51 is directly disposed between the end face of the fixed post 5 and the groove surface of the anti-cavity recess, which can ensure the connection length of the screw 52 in the threaded channel 51 in the fixed post 5 and ensure the locking strength.

[0046] In another specific embodiment, the recessed slot includes an open top slot 61 and an annular groove 62 located below the top slot 61. The structure of the annular groove 62 facilitates the processing of the circular central countersunk hole 42.

[0047] To ensure the tool length when the cutter is lowered, the circumferential groove surface 62 is set parallel to the vertical plane 21. That is, the thickness of the gap between the circumferential groove surface 62 and the oblique cutting plane 22 gradually increases from top to bottom, which can match the oblique cutting direction of the inclined plane and ensure that the machining tools for the circular central countersunk hole 42 and the through groove on the arc-shaped ball platform 44 are all in the direction of vertical cutting, thus ensuring machining accuracy.

[0048] To further ensure machining accuracy, a machining tapered hole 7 is provided between the threaded channels 51 on the clamping part 2. The machining tapered hole 7 gradually transitions from the oblique cutting plane 22 to the vertical plane 21. By setting the machining tapered hole 7, the feed machining of tools of different sizes can be met. At the same time, this setting can effectively shorten the tool loading length, improve the tool machining rigidity, effectively reduce tool vibration during machining, and thus improve tool life.

[0049] This utility model also provides a parts processing device, including processing equipment and any of the parts clamping fixtures in the foregoing embodiments. The clamping part 2 and the fixture body 1 are an integral structure. The parts 4 are clamped and fixed in the clamping part 2, and the fixture body 1 is connected and installed on the processing equipment.

[0050] This invention enables the structural processing of different parts on both sides of part 4 in a single clamping state, improving production efficiency and product accuracy, and reducing the investment in additional equipment and production costs.

[0051] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
