Description

Technical Field

[0001] This utility model relates to the field of machine tool angle head installation technology, specifically an enhanced connection mechanism for machine tool angle heads. Background Technology

[0002] A machine tool angle head is an accessory mounted on the spindle of a machine tool to extend the machining capabilities of the machine tool, enabling it to perform milling, drilling, tapping, and other machining operations at different angles. It is suitable for multi-faceted machining of complex parts.

[0003] Currently, most machine tool angle heads use standard tool holders and mechanical tensioning systems for connection. While this meets basic requirements, the locking force depends on the spindle puller mechanism. If the machine tool spindle puller force is insufficient, such as due to aging of the disc spring, the angle head may loosen, causing safety hazards. Therefore, we need to propose an enhanced connection mechanism for machine tool angle heads. Utility Model Content

[0004] The purpose of this utility model is to provide an enhanced connection mechanism for machine tool angle heads, which achieves rigid fixation of the machine tool angle heads, strengthens the locking force of the machine tool angle heads, improves the installation and fixing effect of the machine tool angle heads, solves the problem of angle heads loosening due to insufficient locking force, and prevents safety hazards, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An enhanced connection mechanism for a machine tool angle head includes a spindle housing and a spindle movably installed within the spindle housing. The machine tool angle head is fixedly installed inside the spindle. A mounting plate is fixedly connected to the surface of the spindle housing.

A clamping block is fixedly installed at one end of the movable frame.

[0007] A ring seat is fixedly connected to the angle head of the machine tool, and a clamping groove is provided in the ring seat. The clamping block is pressed against the clamping groove.

[0008] Preferably, a clamping seat is fixedly installed at the bottom of the fixed seat, and two sets of arc-shaped positioning blocks are symmetrically fixedly connected to the surface of the sealing cylinder.

The arc-shaped positioning blocks are inserted into the arc-shaped grooves, and the sealing cylinder is fixedly installed at the bottom of the fixed seat through the clamping seat.

[0009] Preferably, the surface of the sealing cylinder is symmetrically and fixedly connected with a first mounting seat and a second mounting seat, and both the first mounting seat and the second mounting seat are in communication with the interior of the sealing cylinder.

[0010] Preferably, the connecting mechanism includes a square post, which is fixedly connected to the end of the piston rod. A connecting seat is fixedly connected to the side of the movable frame. A square groove adapted to the square post is opened on the side of the connecting seat. The square post is inserted into the square groove. A fixing screw is provided on the connecting seat. The square post is fixedly installed in the connecting seat by the fixing screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The design of this utility model, including the sealing cylinder, piston, piston rod, moving frame, and clamping block, utilizes hydraulic oil entering the sealing cylinder through the first mounting seat to push the piston. Hydraulic oil on the other side of the piston exits the sealing cylinder through the second mounting seat. The piston then pushes the piston rod, moving frame, and clamping block, enabling the clamping block to clamp into the clamping groove of the annular seat on the machine tool angle head.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] An enhanced connection mechanism for a machine tool angle head includes a spindle housing 1 and a spindle 2 movably installed inside the spindle housing 1. A machine tool angle head 3 is fixedly installed inside the spindle 2. A mounting plate 4 is fixedly connected to the surface of the spindle housing 1.

[0023] A ring seat 20 is fixedly connected to the machine tool angle head 3. A clamping groove 21 is provided in the ring seat 20, and the clamping block 17 is pressed against the clamping groove 21.

[0024] It should be noted that the sealing cylinder 8, piston 15, piston rod 14 and moving frame 16 cooperate to push the clamping block 17, so that the clamping block 17 can be pressed against the clamping groove 21 of the annular seat 20, thereby achieving rigid fixation of the machine tool angle head, strengthening the locking force of the machine tool angle head and improving the installation and fixing effect of the machine tool angle head.

[0025] In an optional embodiment: a clamping seat 9 is fixedly installed at the bottom of the fixed seat 7, and two sets of arc-shaped positioning blocks 10 are symmetrically fixedly connected to the surface of the sealing cylinder 8. Both the bottom of the fixed seat 7 and the top of the clamping seat 9 are provided with arc-shaped grooves 11 opposite to the arc-shaped positioning blocks 10. The arc-shaped positioning blocks 10 are inserted into the arc-shaped grooves 11, and the sealing cylinder 8 is fixedly installed at the bottom of the fixed seat 7 by the clamping seat 9.

[0026] It should be noted that the arc-shaped positioning block 10 and the arc-shaped groove 11 cooperate to position the sealing cylinder 8, thereby improving the fixing effect of the sealing cylinder 8 when the clamping seat 9 is installed at the bottom of the fixed seat 7.

[0027] In an optional embodiment: a first mounting base 12 and a second mounting base 13 are symmetrically fixedly connected to the surface of the sealing cylinder 8, and both the first mounting base 12 and the second mounting base 13 are in communication with the interior of the sealing cylinder 8.

[0028] It should be noted that both the first mounting base 12 and the second mounting base 13 are connected to the liquid supply pipe of the liquid supply equipment (such as a hydraulic pump station). With the cooperation of the hydraulic pump station and the liquid supply pipe, hydraulic oil can be supplied to the sealing cylinder 8 through the first mounting base 12 or the second mounting base 13, and the piston 15 can be moved by the hydraulic oil.

[0029] In an optional embodiment: the connecting mechanism includes a square post 19, which is fixedly connected to the end of the piston rod 14. A connecting seat 18 is fixedly connected to the side of the movable frame 16. A square groove adapted to the square post 19 is opened on the side of the connecting seat 18. The square post 19 is inserted into the square groove. A fixing screw is provided on the connecting seat 18. The square post 19 is fixedly installed in the connecting seat 18 by the fixing screw.

[0030] It should be noted that the square post 19, the connecting seat 18 and the fixing screw work together to install the movable frame 16, so that the movable frame 16 can be fixed to the end of the piston rod 14.

[0031] In an optional embodiment: four sets of guide rails 5 are fixedly installed on the bottom of the spindle housing 1 and the mounting plate 4 in pairs, and slide blocks 6 are slidably installed on each pair of guide rails 5, and the moving frame 16 is fixedly installed on the bottom of the slide blocks 6.

[0032] It should be noted that the guide rail 5 and the slide block 6 work together to guide and position the movable frame 16, enabling the movable frame 16 to move horizontally.

[0033] In an optional embodiment, a sealing ring 22 is provided inside the sealing cylinder 8, and the inner side of the sealing ring 22 is in contact with the surface of the piston rod 14.

[0034] It should be noted that the sealing ring 22 serves to seal the piston rod 14, preventing the hydraulic oil inside the sealing cylinder 8 from leaking out through the piston rod 14.

[0035] In an alternative embodiment, the surface of piston 15 contacts the inner wall of sealing cylinder 8.

[0036] In practical use, after the machine tool angle head 3 is installed inside the spindle 2, hydraulic oil enters the sealing cylinder 8 through the first mounting seat 12 and pushes the piston 15. This causes the hydraulic oil on the other side of the piston 15 to be discharged from the sealing cylinder 8 through the second mounting seat 13. The piston 15 pushes the piston rod 14, the moving frame 16 and the clamping block 17, so that the clamping block 17 can be clamped in the clamping groove 21 of the annular seat 20 on the machine tool angle head 3, thereby achieving rigid fixation of the machine tool angle head 3, strengthening the locking force of the machine tool angle head 3, improving the installation and fixing effect of the machine tool angle head 3, solving the problem of the angle head loosening due to insufficient locking force, and preventing safety hazards.
