Description

Technical fields:

[0001] This application relates to the field of nut processing technology, and in particular to a ball screw nut tapping device. Background technology:

[0002] Ball screw nuts are part of ball screw drive assemblies. They possess advantages such as high precision, high efficiency, high rigidity, and high load-bearing capacity, and are widely used in machine tools, automation equipment, and other fields. They are key components for achieving precise position control and efficient power transmission. Ball screw nuts are typically square in shape, with four holes pre-machined on their end faces. These holes are then threaded using a tapping machine to secure related connecting parts.

[0003] The existing processing technology involves using a clamping assembly to fix the nut, and then changing the position of the nut relative to the tapping tap by moving the clamping assembly, thereby tapping the four holes of the nut. However, this method is prone to deviations in the tapping position due to human error, which in turn affects the installation of the connector and causes product quality defects. Furthermore, manually aligning the tapping tap and the nut holes is time-consuming, which greatly reduces processing efficiency. Utility Model Content:

[0004] To solve the above-mentioned technical problems, this utility model provides a ball screw nut tapping device. The technical problem it solves is that errors caused by manual movement of the tapping cone lead to tapping position deviations, resulting in product quality defects. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A ball screw nut tapping device, comprising:

[0006] A rectangular limiting groove is formed on the upper surface of the tapping machine's operating table;

[0007] The tapping tap is connected to the operating table in the vertical direction by a lifting structure;

[0008] A clamping assembly for securing the ball screw nut is mounted on the upper surface of the operating table.

[0009] The limiting block is connected to the rectangular limiting groove in a sliding structure. The limiting block is connected to the lower end of the clamping assembly in a fixed structure. When the limiting block is located at one of the four corners of the rectangular limiting groove, a tapping tap is used to tap one of the four holes of the nut.

[0010] The power mechanism that drives the tapping tap to rise and fall.

[0011] Furthermore, the clamping assembly includes a clamping seat, the upper end face of which is provided with a sliding groove, and the clamping seat is connected to a clamping block for clamping the nut in a sliding structure.

[0012] The limiting block is connected to the lower end face of the clamping seat.

[0013] Furthermore, a bolt is threaded through one side of the clamping seat, and one end of the bolt passes through the side and is connected to the clamping block in a rotating manner.

[0014] Furthermore, the rectangular limiting groove is set in a square shape.

[0015] The beneficial effects of this utility model are as follows: by setting the limiting block and the rectangular limiting groove, the clamping seat and the nut can move relative to the tapping tap. The four corners of the rectangular limiting groove are used to quickly position the limiting block, thereby ensuring that when the four holes of the ball screw nut are at different corners of the rectangular limiting groove, one hole is always located below the tapping tap, which ensures the accuracy of tapping, greatly reduces the error caused by manual alignment, and improves work efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0022] A ball screw nut tapping device includes a rectangular limiting groove 2 formed on the upper surface of a tapping machine operating table 1; a tapping cone 3 is vertically connected to the operating table 1 via a lifting structure; a clamping assembly for fixing the ball screw nut is provided on the upper surface of the operating table 1, and a limiting block 4 is fixedly connected to the lower end of the clamping assembly via a fixed structure. The limiting block 4 is connected to the rectangular limiting groove 2 via a sliding structure. When the limiting block 4 is located at one of the four corners of the rectangular limiting groove 2, the tapping cone 3 is used to tap one of the four holes of the nut. The power mechanism that drives the tapping cone 3 to rise and fall is described in detail. The connection structure between the tapping cone 3 and the operating table 1 and the power structure that drives the tapping cone 3 to rise and fall are prior art.

[0023] Furthermore, by setting the limiting block 4 and the rectangular limiting groove 2, the clamping seat and the nut can move relative to the tapping tap. The four corners of the rectangular limiting groove are used to quickly position the limiting block, thereby ensuring that when the four holes of the ball screw nut are at different corners of the rectangular limiting groove, one hole is always located below the tapping tap, which ensures the accuracy of tapping, greatly reduces the error caused by manual alignment, and improves work efficiency.

[0024] It should be noted that the clamping assembly includes a clamping seat 5, the upper end face of which is provided with a sliding groove 6. The clamping seat 5 is connected to a clamping block 8 for clamping the nut in a sliding structure. The clamping block 8 fixes the nut and ensures the stability of the nut during the tapping process. The lower end face of the clamping seat 5 is connected to the limiting block 4. When the two adjacent surfaces of the limiting block 4 are in contact with the two adjacent surfaces of the rectangular limiting groove 2, the ball screw nut is positioned to ensure that one hole is located directly below the tapping cone 3.

[0025] It should be noted that a bolt 7 is threaded through one side of the clamping seat 5, and one end of the bolt 7 passes through the side and is connected to the clamping block 8 in a rotating manner. The clamping block 8 is controlled by the engagement of the bolt 7 with the clamping seat 5, so that the clamping block 8 can slide along the slide groove 6, thereby realizing the clamping and release of the nut.

[0026] Specifically, the rectangular limiting groove 2 is square in shape and matches the shape of the nut. By moving the limiting block 4 in different corners of the rectangular limiting groove 2, the four holes of the nut are respectively sent to the bottom of the tapping tap.

[0027] The working principle and process of this utility model are as follows:

[0028] Loosen bolt 7; bolt 7 moves, causing clamping block 8 to move towards clamping seat 5. Place nut on the upper surface of slide groove 6, then tighten bolt 7; bolt 7 moves clamping block 8 to clamp nut. Figure 3 As shown, when the clamping assembly is in the clamping state, the bottom surface and the two adjacent sides of the nut are in contact with the clamping seat 5 and the clamping block 8 respectively, and are fixed by the clamping seat 5 and the clamping block 8, ensuring the stability of the nut during the tapping process; and the width of the nut is equal to the width of the clamping seat 5, ensuring that the nut can be placed in the same position on the clamping seat 5, avoiding the positional deviation between the tapping tap 3 and the hole of the nut.

[0029] The tapping process is as follows Figure 3As shown, the nut has four holes A, B, C, and D, and the four corners of the rectangular limiting groove 2 are A', B', C', and D', respectively. When the clamping assembly clamps the ball screw nut, the limiting block 4 is located at A' of the rectangular limiting groove 2. At this time, the two adjacent surfaces of the limiting block 4 are in contact with the two adjacent surfaces of the rectangular limiting groove 2. The A hole of the nut is located directly below the tapping tap 3. During operation, the power mechanism is started first, and the power mechanism drives the tapping tap 3 to descend vertically to tap the nut. After the first hole is tapped, the power mechanism is started to raise the tapping tap 3. Then, move the clamping seat 5 to the right along the rectangular limiting groove 2 until the limiting block 4 is at position B' of the rectangular limiting groove 2. At this time, the B hole of the nut is directly below the tapping tap 3. Then, start the power mechanism, which drives the tapping tap 3 to descend and tap the nut. The second hole is tapped. Repeat the above operation until all four holes on the nut are tapped. Loosen the bolt 7. The bolt 7 moves and drives the clamping block 8 to move to one side of the clamping seat 5. Remove the nut.
