[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the fixture for processing ejector pins according to this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0019] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical 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 utility model based on the specific circumstances.

[0021] Please see Figures 1 to 3The jig for processing ejector pins according to this utility model includes a base 1; a clamping plate 2 fixedly disposed on the base 1, the clamping plate 2 being perpendicular to the base 1 and having a plurality of positioning grooves 22 arranged thereon; a sliding block 3 slidably locked on the base 1, one side of the sliding block 3 facing the positioning grooves 22; and a fixing block 4 fixedly disposed on the clamping plate 2, the fixing block 4 covering the positioning grooves 22.

[0022] In the above embodiment, firstly, multiple ejector pin raw materials to be processed are sequentially placed in several positioning slots 22 arranged on the clamping plate 2. Each positioning slot 22 ensures that the ejector pin raw materials can be stably and accurately positioned. Then, the sliding block 3, which is slidably locked on the base 1, is manually pushed so that it slides along the base 1 until one side of the sliding block 3 comes into face-to-face contact with the positioning slot 22. At this time, one end of the ejector pin raw material will abut against the sliding block 3. Through the blocking effect of the sliding block 3, one end of all the ejector pin raw materials is aligned flush, ensuring the consistency of the processing reference.

[0023] After alignment, the sliding stop 3 is locked to the base 1 using a locking mechanism to prevent it from moving during processing. Next, the fixing block 4 is fixedly set on the clamping plate 2, covering the positioning groove 22. Through the action of the fixing block 4, all the ejector pin raw materials are further fixed to ensure that they will not be displaced during processing.

[0024] At this point, the ejector pin material is securely fixed on the fixture. Next, machining operations, such as cutting and grinding, can be performed on the other end of the ejector pin material. This fixture design makes machining multiple ejector pins convenient, simple, and easy to operate. Furthermore, because it can simultaneously fix multiple ejector pin materials, it greatly saves time and significantly improves work efficiency.

[0025] Please see Figures 1 to 3 In another embodiment, the base 1 is provided with a slide rail 11, and the bottom of the sliding block 3 is provided with a groove 31 that is adapted to the slide rail 11.

[0026] In the above embodiment, when it is necessary to adjust the position of the sliding block 3, the sliding block 3 slides along the slide rail 11 of the base 1 through the slide groove 31 at its bottom until it reaches the desired position, thereby realizing the stable and precise movement and positioning of the sliding block 3 on the base 1.

[0027] Please see Figures 1 to 3 In another embodiment, one edge of the slide 11 is raised to form a first inclined surface 12, and one edge of the slide groove 31 is recessed to form a second inclined surface 32. When the sliding block 3 is disposed on the base 1, the first inclined surface 12 abuts against the second inclined surface 32.

[0028] In the above embodiment, one edge of the slide rail 11 is designed with an upward-curving first inclined surface 12, while one edge of the bottom groove 31 of the sliding block 3 is recessed inward, forming a corresponding second inclined surface 32. When the sliding block 3 slides along the slide rail 11 to the edge, the first inclined surface 12 and the second inclined surface 32 abut against each other. This design allows the sliding block 3 to automatically slow down its sliding speed and eventually stop when it reaches the predetermined position, achieving precise positioning. At the same time, the design of the inclined surface also increases the stability of the sliding block 3 at this position, preventing it from moving accidentally during processing.

[0029] Please see Figures 1 to 3 In another embodiment, the sliding block 3 is provided with a first through hole 33 extending through it.

[0030] In the above embodiment, the sliding stop 3 is designed with a first through hole 33 that runs through its entirety. The existence of this through hole makes it possible to lock the sliding stop 3. In actual operation, an iron rod can be selected and passed through the first through hole 33 of the sliding stop 3. One end of the iron rod is fixed to the plane of the processing table, so that the sliding stop 3 is firmly locked in the current position by the iron rod. In this way, the sliding stop 3 can be stably maintained in the preset position during any processing process that requires maintaining a fixed state, thereby completing the locking step of the sliding stop 3.

[0031] Please see Figures 1 to 3 In another embodiment, the first through hole 33 is a threaded hole.

[0032] In the above embodiment, when it is necessary to lock the sliding stop 3, a threaded iron rod or bolt can be used and screwed into the threaded hole. As the bolt is rotated deeper, the connection between the sliding stop 3 and the processing table becomes increasingly tight and stable until the head of the bolt is pressed against the surface of the processing table, and the sliding stop 3 is firmly locked in a fixed position. This design not only provides a stable locking effect but also facilitates quick installation and disassembly according to actual needs.

[0033] Please see Figures 1 to 3 In another embodiment, the top and bottom of the clamping plate 2 are provided with two fixing holes 21, one end of the fixing block 4 is provided with a second through hole 41, and the other end of the fixing block 4 is provided with a notch 42. The fixing block 4 can be swung and disposed in the fixing hole 21 located at the bottom of the clamping plate 2 through the second through hole 41.

[0034] In the above embodiment, the clamping plate 2 has two fixing holes 21 at both its top and bottom, and the fixing block 4 has a second through hole 41 at one end and a notch 42 at the other end. The fixing block 4 is connected to the fixing hole 21 at the bottom of the clamping plate 2 through its second through hole 41, allowing it to be swung. When it is necessary to place the ejector pin in the positioning groove 22 of the clamping plate 2, the operator only needs to swing the fixing block 4 to the positioning groove 22 so that the notch 42 is aligned with the fixing hole 21 at the top of the clamping plate 2. Then, by passing a locking pin through the fixing hole 21 at the top of the clamping plate 2 and fixing the notch 42 of the fixing block 4, the fixing block 4 can be easily locked onto the clamping plate 2, completing the entire fixing process. The operation is simple and quick.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
