Description

Technical Field

[0001] This utility model belongs to the field of spindle box machining and positioning, and particularly relates to a positioning fixture for spindle box machining. Background Technology

[0002] A positioning fixture for spindle box machining is a device used to fix the spindle box, ensuring its accurate position during machining, thereby improving machining accuracy and efficiency. By precisely positioning the spindle box within the machine tool, the fixture guarantees the positional accuracy of the machined surface relative to the reference surface. At the same time, the spindle box is kept firm to prevent displacement due to vibration or force during the machining process, thereby reducing spindle box errors and machining deviations and ensuring the dimensional accuracy and geometric tolerances of key parts of the spindle box.

[0003] Currently, most spindle box positioning fixtures use T-bolts and pressure blocks. One end of the pressure block contacts the edge of the spindle box, and the T-bolt inserts into a T-slot inside the worktable. The T-bolt provides tension to the pressure block, and tightening the nut on the T-bolt applies pressure to the pressure block, which in turn applies pressure to the spindle box, thus maintaining its stability. While this type of positioning fixture effectively positions and fixes the spindle box, the pressure block only applies pressure from above. When the cutting force on the spindle box is large, this can cause it to wobble, reducing its machining accuracy. Therefore, we propose a positioning fixture for spindle box machining. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for machining a spindle box, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a positioning fixture for machining a spindle box, comprising: a T-block, a support seat provided above the T-block, and one side of the support seat having an inclined angle, a first locking bolt provided inside the support seat, the first locking bolt being threadedly connected to the inner side of the T-block, a top block contacting the side of the support seat with the inclined angle, the top block having an adapted inclined angle on one side of the support seat, and a second locking bolt provided inside the top block, the second locking bolt being threadedly connected to the inner side of the support seat; The top block has a slide rail on its inner side, and a slider is slidably connected to the inner wall of the slide rail. A third locking bolt is threaded to the inner wall of the slider, and a pressure block is fixedly connected to the side of the slider located outside the slide rail.

[0006] In this technical solution, pressure is applied above the spindle box by a pressure block to maintain the stability of the spindle box's vertical position and prevent the spindle box from shaking.

[0007] In the above technical solution, a support plate is fixedly connected above the top block, the outer surface of the third locking bolt is rotatably connected to the inner wall of the support plate, and the bottom end of the third locking bolt is rotatably connected to the inner bottom wall of the slide.

[0008] In this technical solution, a supporting force is provided for the third locking bolt.

[0009] In the above technical solution, further, a diagonal brace is fixedly connected to one side of the slider, and the other side of the diagonal brace is fixedly connected to the top of the pressure block.

[0010] This technical solution improves the stability of the compressed blocks.

[0011] In the above technical solution, a through hole is further provided on the inner side of the support base, and the first locking bolt is located inside the through hole. A protruding strip is fixedly connected to the lower part of the support base.

[0017] The beneficial effects of this utility model are: 1. This positioning fixture for machining the spindle box uses the cooperation between the top block, the pressure block, and the third locking bolt. The top block applies clamping force to the outside of the spindle box to horizontally position it and maintain the stability of its horizontal position. The third locking bolt serves as the power source to provide power for the movement of the pressure block. The pressure block applies pressure above the spindle box to maintain the stability of its vertical position, prevent the spindle box from shaking, and improve the machining accuracy of the spindle box.

[0018] 2. The positioning fixture for machining the spindle box, through the cooperation between the support seat, the convex strip and the first locking bolt, and through the contact between the convex strip and the T-slot inside the worktable, provides resistance to the support seat, preventing the support seat from moving when the first locking bolt is tightened, thereby improving the stability of the support seat when tightening the first locking bolt and improving the convenience of locking the support seat and the T-block.

[0023] Example 1: This example provides a positioning fixture for machining a spindle box, including a T-block 1. The T-block 1 has a support base 2 on top, with one side of the support base 2 having an inclined angle. A first locking bolt 3 is installed inside the support base 2 and is threadedly connected to the inner side of the T-block 1. A top block 4 contacts the side of the support base 2 with the inclined angle, and the top block 4 has a matching inclined angle on one side of the support base 2. A second locking bolt 5 is installed inside the top block 4 and is threadedly connected to the inner side of the support base 2. By placing the T-block 1 into the T-groove inside the worktable, support is provided for the components above. The support base 2 is connected to the T-block 1 via the first locking bolt 3, giving the support base 2 stability. When the second locking bolt 5 pushes the top block 4 downwards via the inclined angle of the support base 2, the top block 4 has a forward movement trajectory.

[0024] A slide 6 is provided on the inner side of the top block 4. A slider 7 is slidably connected to the inner wall of the slide 6. A third locking bolt 8 is threadedly connected to the inner wall of the slider 7. A pressure block 9 is fixedly connected to the side of the slider 7 located outside the slide 6.

[0025] The slide rail 6 provides space for the slider 7 to move, the third locking bolt 8 provides power for the slider 7 and the pressure block 9 to move, and the pressure block 9 applies pressure above the spindle box.

[0026] Example 2: This example provides a positioning fixture for machining a spindle box. In addition to the technical solution of the above example, it also has the following technical features: a support plate 10 is fixedly connected above the top block 4; the outer surface of the third locking bolt 8 is rotatably connected to the inner wall of the support plate 10; and the bottom end of the third locking bolt 8 is rotatably connected to the inner bottom wall of the slide 6.

[0027] The support plate 10 provides support for the third locking bolt 8, thereby maintaining the stability of the third locking bolt 8.

[0028] Example 3: This example provides a positioning fixture for spindle box machining. In addition to the technical solutions of the above examples, it also has the following technical features: a diagonal brace 11 is fixedly connected to one side of the slider 7, and the other side of the diagonal brace 11 is fixedly connected to the top of the pressure block 9.

[0029] The inclined brace 11 provides support for the pressure block 9, improves the stability of the pressure block 9, and prevents the pressure block 9 from being subjected to the opposite force from below, which would cause the pressure block 9 to deform.

[0030] Example 4: This example provides a positioning fixture for spindle box machining. In addition to the technical solutions of the above examples, it also has the following technical features: a through hole 12 is provided on the inner side of the support base 2, and the first locking bolt 3 is located inside the through hole 12. A protrusion 16 is fixedly connected to the lower part of the support base 2.

[0031] The support seat 2 provides a space for the first locking bolt 3 through the through hole 12. The support seat 2 contacts the T-slot inside the workbench through the protrusion 16, which provides resistance to the support seat 2 and keeps the support seat 2 stable when the first locking bolt 3 is tightened.

[0032] Example 5: This example provides a positioning fixture for machining a spindle box. In addition to the technical solutions of the above examples, it also has the following technical features: a channel 13 is provided on the inner side of the top block 4, and the second locking bolt 5 is located inside the channel 13.

[0033] The top block 4 has space to move through the channel 13. When the second locking bolt 5 is tightened, the top block 4 will be pushed to move. The position difference between the top block 4 and the support 2 will be generated through the channel 13.

[0034] Example 6: This example provides a positioning fixture for machining a spindle box. In addition to the technical solutions of the above examples, it also has the following technical features: a slide bar 14 is fixedly connected to one side of the top block 4 on the support base 2. A slide groove 15 is opened on the inner side of the top block 4. The inner wall of the slide groove 15 is in contact with the outer surface of the slide bar 14.

[0035] Both the slider 14 and the groove 15 are T-shaped. The slider 14 and the support base 2 are integrally formed. The slider 14 provides support and guidance for the top block 4, thereby maintaining the stability of the top block 4. The groove 15 of the top block 4 receives the supporting force of the slider 14.

[0036] Working principle: The spindle box is stabilized by applying downward pressure and clamping force at its four corners through four top blocks 4 and pressure blocks 9. First, push the T-block 1 into the T-slot of the worktable, then place the support seat 2 on top of the T-block 1, and simultaneously insert the convex strip 16 into the T-slot of the worktable. Then, screw the first locking bolt 3 into the T-block 1, but do not tighten it yet. Next, align the sliding groove 15 inside the top block 4 with the sliding strip 14, and push the top block 4 downward. Then, screw the second locking bolt 5 into the support seat 2, but do not tighten it yet. Finally, push the support seat 2 to move the top block 4 and T-block 1 towards the spindle box. Next, bring the top block 4 into contact with the outside of the spindle box, and then tighten the first locking bolt 3 and the second locking bolt 5. After the first locking bolt 3 is tightened, the T-block 1 and the support seat 2 are firmly fixed above the worktable, and the support seat 2 is stabilized. After the second locking bolt 5 is tightened, the tilt angle between the support seat 2 and the top block 4 is used to push the top block 4 into close contact with the outside of the spindle box, restricting the horizontal movement of the spindle box. Then, tighten the third locking bolt 8. After the third locking bolt 8 is tightened, it pushes the slider 7 and the pressure block 9 to move downward. Then, the pressure block 9 contacts the top of the spindle box and applies pressure to the top of the spindle box to maintain the vertical stability of the spindle box.
