Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for machining, and in particular to an internal support claw device. Background Technology

[0002] In the machining industry, CNC lathes are one of the core pieces of equipment for high-precision parts processing. As a key component of the lathe's clamping system, the accuracy of the soft jaws directly affects the machining quality of the workpiece. When soft jaws wear out or deform due to long-term use, they need to be repaired through a jaw-repairing process to restore clamping accuracy. During the jaw-repairing process, an internal support jaw-repairing tool is an indispensable auxiliary tool. Its function is to apply a uniform clamping force to the soft jaws through internal support, ensuring the stability of the soft jaws' position during the repair process, thereby guaranteeing the repair accuracy.

[0003] Currently, the commonly available internal support claw tools on the market have the following significant problems:

[0004] Complex structure leads to cumbersome operation: some devices use multiple sets of independent drive components to control the opening and closing of the telescopic claw. The precision requirements for the cooperation between the components are extremely high, which not only increases the manufacturing difficulty and cost, but also requires operators to spend a lot of time on debugging and calibration, which seriously affects the processing efficiency.

[0005] Insufficient synchronization affects clamping accuracy: Traditional internal support devices often use simple mechanical structures, such as linkages or springs, to connect the telescopic claws, making it difficult to achieve synchronous enlargement or reduction of multiple claws. When the drive component rotates, the moving distance and speed of each telescopic claw differ, resulting in uneven force on the soft claws. After grinding, the clamping surface of the soft claws deviates, failing to meet the requirements of high-precision machining.

[0006] Poor installation stability poses safety hazards: The assembly structure between the base, rotating disk, and telescopic claw of the existing device is not optimized enough. It is prone to vibration during high-speed grinding, which not only affects the grinding quality but may also cause parts to loosen or even fall off, posing a safety risk. Utility Model Content

[0007] In view of this, the present invention aims to provide an internal support claw tool to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0008] The technical solution of this utility model embodiment is implemented as follows:

[0009] The internal support claw tool includes a base, a rotating disk, telescopic claws, and a pressure cap;

[0010] The rotating disk is positioned above the base, and a spiral groove is provided below it;

[0011] The telescopic claw is disposed between the rotating disk and the base, and has a slot corresponding to the spiral annular groove. By rotating the rotating disk, the spiral annular groove and the slot are engaged to drive the telescopic claw to expand or shrink synchronously.

[0012] The pressure cap is installed on the base to fix the relative positions of the components.

[0013] Preferably, the rotating disk has an internal hexagonal hole in the middle for rotating the rotating disk by using an internal hexagonal wrench.

[0014] Preferably, the pressure cap and the base are connected by fixing nails.

[0015] Preferably, the number of telescopic claws is three, which are evenly distributed between the rotating disk and the base.

[0016] Preferably, the base is provided with a guide groove that cooperates with the telescopic claw to support and guide the movement of the telescopic claw.

[0017] Preferably, the spiral trajectory of the spiral groove is adapted to the shape of the slot to ensure that the telescopic claw can smoothly and synchronously enlarge or shrink.

[0018] Preferably, the rotating disk is located above the base, the telescopic claw is disposed between the rotating disk and the base, and the pressure cover covers part of the structure of the telescopic claw and the rotating disk.

[0019] The present invention has the following advantages due to the adoption of the above technical solution:

[0020] I. Simple and efficient structure: Through the helical cooperation structure of the rotating disk and the telescopic claw, multi-claw synchronous movement can be achieved without complex transmission components, which simplifies the device structure and reduces manufacturing costs and maintenance difficulty.

[0021] 2. Precise Synchronous Support: The precise fit between the spiral annular groove and the slot ensures that the three telescopic claws move synchronously, so that the inner wall of the soft claw is subjected to uniform clamping force, which significantly improves the positional accuracy of the soft claw during the grinding process, thereby improving the processing quality of the workpiece.

[0022] 3. Convenient and stable operation: The design of the internal hexagonal hole facilitates quick manual adjustment of the clamping force, and the tight connection between the pressure cap and the base effectively enhances the device's anti-vibration capability, ensuring the safety and stability of the grinding process.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the accompanying drawings and specific circumstances.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1-5 The present invention provides an internal support claw tool, including a base 1, a rotating disk 2, a telescopic claw 3, and a pressure cap 4; the rotating disk 2 is disposed above the base 1, and has a spiral annular groove 5 below it; the telescopic claw 3 is disposed between the rotating disk 2 and the base 1, and has a slot 6 corresponding to the spiral annular groove 5, and by rotating the rotating disk 2, the spiral annular groove 5 and the slot 6 cooperate to drive the telescopic claw 3 to expand or shrink synchronously; the pressure cap 4 is installed on the base 1 to fix the relative positions of the components.

[0036] In this embodiment, specifically, the rotating disk 2 has an internal hexagonal hole 7 in the middle, which is used to rotate the rotating disk 2 by an internal hexagonal wrench, and the pressure cover 4 is connected to the base 1 by a fixing nail 8.

[0037] In this embodiment, specifically, there are three telescopic claws 3, which are evenly distributed between the rotating disk 2 and the base 1. The base 1 is provided with a guide groove 9 that cooperates with the telescopic claws 3 to support and guide the movement of the telescopic claws 3.

[0038] In this embodiment, specifically, the spiral trajectory of the spiral groove 5 is adapted to the shape of the slot 6 to ensure that the telescopic claw 3 can be smoothly and synchronously enlarged or reduced. The rotating disk 2 is located above the base 1, the telescopic claw 3 is set between the rotating disk 2 and the base 1, and the pressure cover 4 covers part of the structure of the telescopic claw 3 and the rotating disk 2.

[0039] When this utility model is in operation:

[0040] I. Assembly Steps

[0041] 1. Base installation: Fix base 1 to the CNC lathe worktable, ensuring that the positioning column is vertically upward.

[0042] 2. Telescopic claw positioning: Insert the three telescopic claws 3 into the three guide grooves 9 of the base 1 respectively, so that the slots 6 of the telescopic claws 3 face upward.

[0043] 3. Rotary disk installation: Insert the center hole of the rotating disk 2 into the positioning post of the base 1, so that the spiral ring groove 5 on the lower surface of the rotating disk 2 engages with the slot 6 of the telescopic claw 3. The protruding part of the spiral ring groove 5 is embedded in the slot 6.

[0044] 4. Fixing the cover: Place the cover 4 above the rotating disk 2 and fasten the cover 4 to the base 1 with the fixing nails 8 to complete the overall assembly.

[0045] II. Work Process

[0046] 1. Blessed with soft claws

[0047] Place the device inside the soft claw to be repaired, so that the arc-shaped support surface of the telescopic claw 3 initially contacts the inner wall of the soft claw.

[0048] Insert an Allen wrench into the Allen hole 7 of the rotating disk 2 and rotate the rotating disk 2 clockwise. Due to the spiral trajectory of the spiral groove 5, the inner wall of the slot 6 contacts the side wall of the spiral groove 5, and the rotational motion of the spiral groove 5 is converted into the radial outward movement of the telescopic claw 3.

[0049] Because the parameters of the three spiral grooves 5 are completely identical, the three telescopic claws 3 move outward synchronously until the arc-shaped support surface is evenly attached to the inner wall of the soft claw, forming a stable internal support.

[0050] 2. Grinding operation

[0051] Start the CNC lathe and perform turning and grinding on the outer cylindrical surface of the soft jaw. Since the pressure cover 4 and the base 1 are fastened with fixing nails 8, the rotary disk 2 and the telescopic jaw 3 maintain a stable position during grinding vibration, avoiding deviations in grinding accuracy due to loosening.

[0052] 3. Loosen and remove

[0053] After grinding, rotate the rotating disk 2 counterclockwise. The spiral ring groove 5 pushes the slot 6 in the opposite direction. The telescopic claw 3 retracts radially inward along the base guide groove 9 until the arc-shaped support surface disengages from the inner wall of the soft claw. The device can then be easily removed.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
