Description

Technical Field

[0001] This utility model relates to the field of cutting-edge technology, specifically a clamping tip with high stability. Background Technology

[0002] In the machining industry, clamping centers are the core components for achieving precise workpiece positioning and stable rotation. They are widely used in various workpiece machining processes such as turning, milling, and grinding, and their performance has a decisive impact on product machining accuracy, production efficiency, and operational safety.

[0003] Traditional centers are mostly one-piece structures. Once the center tip wears out or needs to be adapted to different workpiece sizes, the entire center must be replaced. This not only increases equipment procurement costs but also causes excessive production interruptions due to the cumbersome replacement process, severely restricting production continuity. With the diversification of processing needs, some split centers have emerged, but they have shortcomings. Because they mostly use a single bolt fixing or simple snap-fit ​​connection, they are prone to loosening and displacement under dynamic loads such as centrifugal force and cutting resistance during high-speed rotational machining. This can lead to workpiece rotation axis misalignment, increased surface roughness, poor dimensional accuracy, and even workpiece falling off, causing safety accidents.

[0004] Therefore, we propose a clamping tip with high stability to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] The purpose of this invention is to provide a clamping tip with high stability to solve the problems currently found in the market as described in the background.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the present invention provides the following technical solution: a highly stable clamping tip, comprising a tip shank, a tip seat mounted above the tip shank, a tip head disposed inside the upper end of the tip seat, an installation groove being provided inside the lower end of the tip head, and a plurality of connecting grooves being provided at equal angles inside the tip head, and the installation groove and the connecting grooves being interconnected.

[0009] An installation base is fixedly installed inside the top seat. The installation base is in concave-convex fit with the installation groove. Several sets of installation blocks are slidably installed inside the installation base at equal angles. Each installation block is in concave-convex fit with the corresponding connecting groove. A release element is installed between the installation block and the top seat. The release element is used to drive the installation block to disengage from the connecting groove.

[0010] Furthermore, positioning grooves are provided on both the left and right sides of the tip, the positioning grooves are in clearance fit with the positioning strip, and the positioning strip is fixedly installed inside the tip seat.

[0011] The above technical solution enables the initial positioning of the center tip through the combined action of the positioning groove and the positioning strip.

[0012] Furthermore, the mounting block is inclined above the tip, and a pressure spring is connected between the mounting block and the mounting base, and the mounting block is pressed tightly inside the connecting groove by the pressure spring.

[0013] The above technical solution ensures that during the installation process of the tip, the mounting block is squeezed and then pressed tightly into the connecting groove of the tip by the pressure spring.

[0014] Furthermore, the release element includes a drive rod rotatably mounted in the center seat via a damping bearing. A drive block is fixedly connected to the left end of the drive rod, and several sets of reels are mounted on the drive rod. A traction line is wound on the reels, and one end of the traction line is fixed to the side of the mounting block near the center of the mounting seat.

[0015] The above technical solution enables the drive block to drive the drive rod to rotate, thereby causing the traction wire to wind onto the reel.

[0016] Furthermore, a fixed pulley is attached to the middle of the traction line, and the fixed pulley is installed inside the mounting base, and the winding direction of several traction lines on the corresponding reels is the same.

[0017] The above technical solution enables the traction line to be guided by the fixed pulley, and allows for the simultaneous winding of several traction lines.

[0018] Furthermore, the mounting block, traction line, and spool are configured in a one-to-one correspondence.

[0019] The above technical solution enables the displacement of several mounting blocks.

[0020] 3. Beneficial effects:

[0021] Compared with the prior art, the technical solution provided by this utility model has a more stable clamping tip, which enables quick replacement of the tip through the mounting block and release component. Furthermore, under the action of rotation and centrifugal force, it can improve the firmness and stability during operation. The specific details are as follows:

[0022] During the installation of the center head, the initial positioning is achieved by utilizing the cooperation between the positioning groove and the positioning strip, so that the mounting groove at the lower end fits the mounting seat inside the center head to achieve axial positioning. Due to the elastic force of the pressure spring, the mounting block moves towards the center head. Its inclined upper end is squeezed during the downward pressing of the center head. After the center head is in place, the mounting block is inserted into the connecting groove and tightly fixed by the pressure spring, completing the quick installation and fixing of the center head. At the same time, when the center is working, under the centrifugal force of rotation, the mounting block will fit more tightly inside the connecting groove, making the connection between the center head and the center head more secure and improving the stability of use.

[0023] When the tip of the center head wears down due to prolonged use, rotating the drive block in the release mechanism will cause the drive rod to rotate, making the spool rotate synchronously and tighten the traction wire. Under the guidance of the fixed pulley, the traction wire pulls the mounting block to overcome the elastic force of the pressure spring and move towards the center of the mounting base, disengaging from the connecting groove. At this time, the center head can be removed from the center head base and replaced with a new center head. After releasing the drive block, the mounting block will reset under the action of the pressure spring, ready for the next installation. Attached Figure Description

[0034] Please see Figure 1-5A highly stable clamping tip includes a tip shank 1, a tip seat 2 mounted above the tip shank 1, a tip head 3 disposed inside the upper end of the tip seat 2, a mounting groove 32 formed inside the lower end of the tip head 3, and several connecting grooves 33 formed at equal angles inside the tip head 3, with the mounting grooves 32 and the connecting grooves 33 communicating with each other; a mounting base 4 is fixedly mounted inside the tip seat 2, the mounting base 4 engaging with the mounting groove 32, and several sets of mounting blocks 5 are slidably mounted at equal angles inside the mounting base 4, with each mounting block... 5 is in concave-convex fit with the corresponding connecting groove 33, and a release element 6 is installed between the mounting block 5 and the top seat 2. The release element 6 is used to drive the mounting block 5 out of the connecting groove 33; positioning grooves 31 are provided on both the left and right sides of the top head 3. The positioning grooves 31 are in clearance fit with the positioning strip 21, and the positioning strip 21 is fixedly installed inside the top seat 2; the mounting block 5 is inclined on the upper side near the top head 3, and a pressure spring 7 is connected between the mounting block 5 and the mounting seat 4. The mounting block 5 is pressed tightly inside the connecting groove 33 by the pressure spring 7.

[0035] When installing a new center head 3, the initial positioning is achieved by using the cooperation between the positioning groove 31 and the positioning strip 21, so that the mounting groove 32 at the lower end cooperates with the mounting seat 4 in the center head 2 to achieve axial positioning. Due to the elastic force of the pressure spring 7, the mounting block 5 moves towards the center head 3. Its inclined upper end is squeezed during the pressing of the center head 3. After the center head 3 is in place, the mounting block 5 is inserted into the connecting groove 33 and is tightly fixed by the pressure spring 7, thus completing the quick installation and fixing of the center head 3. At the same time, when the center is working, under the centrifugal force of rotation, the mounting block 5 will fit more tightly inside the connecting groove 33, making the connection between the center head 3 and the center head 2 more secure and improving the stability of use.

[0036] The release component 6 includes a drive rod 62 rotatably mounted in the center seat 2 via a damping bearing. A drive block 61 is fixedly connected to the left end of the drive rod 62, and several sets of coils 63 are mounted on the drive rod 62. A traction line 64 is wound on the coils 63, and one end of the traction line 64 is fixed to the side of the mounting block 5 near the center of the mounting seat 4. A fixed pulley 65 is attached to the middle of the traction line 64, and the fixed pulley 65 is installed inside the mounting seat 4. The winding direction of the several traction lines 64 on the corresponding coils 63 is the same. The mounting block 5, the traction line 64 and the coil 63 are arranged in a one-to-one correspondence.

[0037] When the tip of the tip 3 wears down due to long-term use, the drive block 61 in the release component 6 is rotated, which drives the drive rod 62 to rotate, causing the wire spool 63 to rotate synchronously and tighten the traction wire 64. Under the guidance of the fixed pulley 65, the traction wire 64 pulls the mounting block 5 to overcome the elastic force of the pressure spring 7 and move towards the center of the mounting base 4, disengaging from the connecting groove 33. At this time, the worn tip 3 can be removed from the tip base 2 and replaced with a new tip 3. After releasing the drive block 61, the mounting block 5 is reset under the action of the pressure spring 7, waiting for the next installation.

[0038] Working principle: When using this highly stable clamping tip, such as Figure 1-5 As shown, when installing a new center head 3, the initial positioning is achieved by the cooperation between the positioning groove 31 and the positioning strip 21. The mounting block 5 is squeezed during the pressing of the center head 3. After the center head 3 is in place, the mounting block 5 is inserted into the connecting groove 33 and tightly fixed by the pressure spring 7, thus completing the quick installation and fixing of the center head 3. When the center is working, the mounting block 5 will fit more tightly inside the connecting groove 33 by the centrifugal force of rotation, making the connection between the center head 3 and the center seat 2 more secure and improving the stability of use. When it is necessary to replace the worn center head 3, the drive rod 62 is rotated by the drive block 61, and the mounting block 5 is pulled out of the connecting groove 33 by the traction line 64, so that the worn center head 3 can be taken out and replaced with a new center head 3.
