Description

Technical Field

[0001] This utility model relates to the field of workpiece positioning technology, specifically a positioning fixture for machining columnar products. Background Technology

[0002] In machining, positioning the workpiece ensures that it is in the correct position relative to the tool or machine tool coordinate system in the machine tool or fixture, so as to ensure that the machining dimensions, shape and positional accuracy meet the design requirements. The positioning datum restricts the degree of freedom of the workpiece, keeps the relative position of the tool and the workpiece consistent, and avoids dimensional deviations due to positional deviations.

[0003] The prior art, patent CN222037671U, discloses a cylindrical workpiece clamping device. A slide rail is provided on the other side of the machine base, and a column is slidably connected to the slide rail. A lead screw is connected to the bottom of the column via a ball screw nut. The lead screw is mounted on the upper side of the slide rail via a bearing seat. A motor is mounted at one end of the lead screw and is connected to the lead screw for transmission. A rotating seat is provided above the column, and a connecting shaft is connected to the rotating seat. A top block is connected to the end of the connecting shaft, and the top block is correspondingly positioned with the clamping plate. This prior art, when fixing a cylindrical workpiece, only requires pre-fixing one side of the clamping plate and positioning the workpiece through the top block. It is simple to operate, saves time, and avoids workpiece loosening and clamping misalignment, thus possessing good practicality.

[0004] Although the design utilizes components such as top blocks and chucks to improve the rapid positioning of cylindrical workpieces and ensure their stability during processing, the shape of the workpieces often necessitates manual positioning when placed on the positioning table, followed by fixing with bolts or other materials to ensure their stability during processing. This operation not only increases the labor intensity of the workers but also hinders the improvement of processing efficiency for cylindrical workpieces. Utility Model Content

[0025] 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.

[0026] This utility model provides a positioning fixture for machining columnar products, such as... Figures 1-6 As shown, it includes a mounting plate 1, and a positioning component is provided at the top of the mounting plate 1. The positioning component includes a positioning platform 2 installed at the top of the mounting plate 1. A straight groove 3 is opened inside the positioning platform 2. A horizontal plate 4 is fixedly connected to the inner wall of the straight groove 3. A locking rod 5 is slidably connected inside the horizontal plate 4. A locking strip 7 is fixedly connected inside the locking rod 5 through a connecting spring 6. The end of the locking strip 7 is rotatably connected to the inside of the locking rod 5 through a rotating shaft 8. The bottom end of the locking rod 5 is fixedly connected to the top of the positioning platform 2 through a return spring 9. A dust removal component is provided on one side of the mounting plate 1.

[0027] The positioning assembly also includes a snap-fit ​​platform 10 mounted on the top of the positioning platform 2. The snap-fit ​​rod 5 slides inside the snap-fit ​​platform 10. A piston 11 is slidably connected to the top of the snap-fit ​​rod 5. An adsorption hole 12 is opened on the outer wall of the snap-fit ​​rod 5 at the piston 12.

[0028] The dust removal assembly includes an extension plate 13 mounted on one side of the mounting plate 1, an electric push rod 14 mounted on the top of the extension plate 13, and a cleaning rod 15 mounted on the output end of the electric push rod 14.

[0029] The top end of the cleaning rod 15 is threaded with a lead screw 16, the bottom end of the lead screw 16 is rotatably sleeved with a flexible strip 17, and the bottom end of the flexible strip 17 is fixedly connected with a brush.

[0030] A ring seat 18 is fixedly sleeved on the outer wall of the rotating shaft 8. A telescopic ratchet 19 is installed on the side wall of the ring seat 18. The outer wall of the locking bar 7 is engaged with the telescopic ratchet 19 through the locking rod 20.

[0031] Specifically, by setting up the positioning components, the cooperation of various parts can improve the rapid positioning of materials and processing equipment, reduce the labor intensity of manual positioning by operators, and improve processing efficiency. When processing, the material is placed on the positioning table 2, and the weight of the material will press down the clamping rod 5. Since the bottom end of the clamping rod 5 is connected to the positioning table 2 through the return spring 9, when its hole is aligned with the hole of the material, the material properties of the spring will cause the clamping rod 5 to rise quickly. When rising, the clamping strip 7 connected to the side wall of the clamping rod 5 through the connecting spring 6 will rotate with the rotation of the rotating shaft 8, thereby quickly clamping the material. Furthermore, through the cooperation of the ring seat 18, the telescopic ratchet 19 and the clamping rod 20, the clamping strip 7 will not be affected by the rotation of the spring 6. To address the issue of material resetting due to shaking, when the grooves in the processed material are deep, a lifting rod can be inserted into the straight groove 3, causing the locking rod 5 to slide within the horizontal plate 4, thereby locking the processed material above. This component has a simple structure and strong practicality, improving material positioning efficiency and stability during processing through the cooperation of various components. With the dust removal component, the electric push rod 14 can be activated, causing the push rod to move the cleaning rod 15, which in turn uses the soft strip 17 and its brush to clean the processed material, preventing impurities and debris from adhering to the processed material and affecting the processing quality. The position of the brush can be adjusted by rotating the lead screw 16 to accommodate columnar materials of different sizes.

[0032] Mounting bases 21 are fixedly connected to the four corners of the top of the mounting plate 1, and mounting bolts are threaded to the top of the mounting bases 21.

[0033] The top of the mounting plate 1 is fitted with a storage box 22, and the inner wall of the storage box 22 is fitted with a sealing cap.

[0034] A positioning ring 23 is installed at the top of the mounting plate 1, and there are several positioning rings 23.

[0035] Specifically, the mounting plate 1 can be quickly and stably connected to the external processing platform through the multiple mounting seats 21 on the mounting plate 1. The tightness of the connection can be improved by rotating the mounting bolts to prevent the mounting plate 1 from shaking during processing. The storage box 22 can collect the cleaned debris in a unified manner to prevent it from falling on the processing platform and affecting the operator's operation.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
