Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically a general-purpose bracket for machining. Background Technology

[0002] Although existing machining brackets are constantly being innovated and developed, and basically meet people's needs, there is still room for improvement.

[0003] For example, patent document CN221436435U discloses a universal machining bracket, including a support plate. A fixing block is fixedly connected to the top of the support plate, and a connecting rod is rotatably connected to one side of the fixing block. A connecting block is fixedly connected to the outer circumference of the connecting rod, and a placement plate is fixedly connected to the top of the connecting block. A groove is formed on the top of the support plate, and a protrusion is slidably connected within the groove. A rack is fixedly connected to the top of the protrusion, and a gear is fixedly connected to the outer circumference of the connecting rod, with the gear meshing with the rack. This design not only allows the protrusion to move along the groove to a suitable position via a first threaded rod, thus achieving bracket angle adjustment and greatly increasing the bracket's application range, but also allows two take-up rollers to rotate clockwise via the output shaft of a self-locking motor, facilitating the clamping of parts of different thicknesses.

[0004] Although the bracket assembly described above can change the height and adjust the tilt angle, its support bottom is fixed to the ground, which means that the top support part can only be tilted left and right or forward and backward. The overall adjustment applicability is low. Therefore, a universal mechanically processed bracket is needed to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a universal bracket for machining, so as to solve the problem that although the bracket assembly mentioned in the background art can change the height and adjust the tilt angle, its support bottom is fixed to the ground, which means that its top support part can only be tilted left and right or forward and backward, resulting in low overall adjustment applicability.

[0006] This utility model provides the following technical solution: a general-purpose bracket for machining, including a support mechanism, wherein the support mechanism includes a tray for placing mechanical workpieces; It also includes a support mechanism, which includes a support base connected to the ground and a lifting screw screwed into a screw hole in the support base; And, a U-shaped seat and a U-shaped sleeve connected between the pallet and the lifting screw and fitted with bearings; Both sides of the U-shaped seat are connected to a second threaded sleeve into which a positioning screw is screwed, and the top of the positioning screw presses against the support plate for positioning.

[0007] To achieve the above technical solution, a lifting screw is used to rotate in the screw hole of the support base to achieve lifting. In conjunction with the U-shaped seat and U-shaped sleeve, the tilt direction changes with the lifting screw, so that the pallet can be tilted and lifted in multiple directions. Compared with the existing technology, the tilt adjustment direction of this device is more comprehensive, which improves the applicability of the device. At the same time, the overall operation is more convenient and easy to use.

[0008] As a further improvement to this utility model, handles are connected around the perimeter of the tray.

[0009] The above technical solution facilitates gripping of the pallet.

[0010] As a further improvement to this utility model, each of the four corners of the top of the pallet is connected to a first threaded sleeve, and a clamping screw for clamping the workpiece is screwed into the first threaded sleeve.

[0011] The above technical solution enables the workpiece to be clamped and limited.

[0012] As a further improvement to this utility model, the surface of the tray is provided with anti-slip texture.

[0013] The above technical solution improves the anti-slip effect of the pallet surface.

[0014] As a further improvement to this utility model, the length of the support base and the lifting screw is at least 50cm.

[0015] The above technical solution ensures the effective adjustment stroke of the lifting screw and support base.

[0016] As a further improvement to this utility model, the extrusion portion at the top of the positioning screw is designed in a spherical shape.

[0017] The above technical solution improves the extrusion positioning effect of the extrusion section on the pallet.

[0018] As a further improvement to this utility model, the second threaded sleeve is installed on the rotation trajectory of the U-shaped sleeve.

[0019] The above technical solution improves the stability of the positioning screw in positioning the pallet.

[0020] The technical effects and advantages of this utility model are as follows: This utility model uses a lifting screw that rotates in the screw hole of the support base to achieve lifting and lowering. With the help of the U-shaped seat and U-shaped sleeve, the tilting direction changes with the lifting screw, so that the pallet can be tilted and adjusted in multiple directions.

[0021] Compared with the prior art, this invention provides a more comprehensive tilt adjustment direction, enhancing its applicability, while also making overall operation more convenient and user-friendly. Attached Figure Description

[0028] Example: Referring to the accompanying drawings, this utility model provides a general-purpose support bracket for machining, including a support mechanism 100. The support mechanism 100 includes a support plate 111 for placing mechanical workpieces. Handles 1011 are connected around the support plate 111. First threaded sleeves 112 are connected to the four corners of the top of the support plate 111, and clamping screws 113 for clamping workpieces are screwed into the first threaded sleeves 112. Anti-slip textures are provided on the surface of the support plate 111. It also includes a support mechanism 200, which includes a support base 211 connected to the ground and a lifting screw 212 screwed into a screw hole in the support base 211; And, a U-shaped seat 2031 and a U-shaped sleeve 2032 connected between the pallet 111 and the lifting screw 212 and connected by bearings; Both sides of the U-shaped seat 2031 are connected to a second threaded sleeve 214 that is screwed into the positioning screw 215. The top of the positioning screw 215 presses against the support plate 111 for positioning. The length of the support seat 211 and the lifting screw 212 is at least 50cm. The pressing part 216 at the top of the positioning screw 215 is spherical. The second threaded sleeve 214 is installed on the rotation trajectory of the U-shaped sleeve 2032.

[0029] When the height or tilt angle needs to be adjusted, first hold the handles 1011 around the pallet 111 and rotate the pallet 111 to allow the lifting screw 212 to rotate in the screw hole of the support 211 to adjust the height and the tilt direction of the U-shaped seat 2031 and the U-shaped sleeve 2032. After adjustment, rotate the two positioning screws 215 in sequence to allow the positioning screws 215 to move under the engagement of the second screw sleeve 214 and press the pressing part 216 against the bottom end of the pallet 111, thereby limiting the tilt angle of the pallet 111. After the height and tilt angle of the pallet 111 are adjusted, the workpiece is placed on the top of the pallet 111. Then, the clamping screw 113 is rotated to move under the meshing action of the first screw sleeve 112, so that the ends of several clamping screws 113 clamp and limit the workpiece.
