A tooling for turning internal V-grooves in pairs of semi-clamps

Abstract

This utility model relates to the field of machining technology, and in particular to a tooling for turning inner V-grooves of paired half-clamps. The tooling includes a clamping cylinder and an upper pressure block. The clamping cylinder has a clamping through hole along its axial direction. A tooling cylinder is coaxially located at the front end of the clamping cylinder, and a tooling hole is coaxially located at the front end of the tooling cylinder. Lug slots are symmetrically located on both sides of the tooling hole diameter on the end face of the tooling cylinder, communicating with the tooling hole. An upper pressure block is installed on the end face of the tooling cylinder corresponding to each lug slot via an upper clamping bolt. By placing the paired half-clamps in the tooling hole, with the lugs at both ends of the two half-clamps located in their corresponding lug slots, and simultaneously clamping the lugs with the upper pressure block using the upper clamping bolts, both half-clamps are simultaneously fixed. The tooling is then mounted on a lathe through the clamping through hole, allowing for the machining of the inner V-grooves of the two half-clamps. During machining, there is no need to repeatedly calibrate the position of the half-clamps.

Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a tooling for turning inner V-grooves in pairs of half clamps. Background Technology

[0002] In fields such as mechanical manufacturing, automotive engineering, pipeline connections, and aerospace, half-clamps are important fastening connectors, often used in pairs to secure shafts and pipes. The structural symmetry and dimensional accuracy of paired half-clamps directly affect the stability and sealing of the connection. The inner V-groove is a key feature for the fit between the half-clamp and its matching parts, and its machining accuracy is crucial to the assembly effect.

[0003] Currently, when machining the inner V-groove of a semi-clamp, a single semi-clamp is usually fixed to the lathe or milling machine worktable with bolts, pressure plates or general-purpose fixtures. After machining the inner V-groove on one side, the other semi-clamp is disassembled, flipped and re-clamped to machine the inner V-groove at the corresponding position.

[0004] On the one hand, single-piece clamping requires repeated calibration of the positioning reference, which is not only cumbersome and time-consuming, but also prone to positioning errors due to multiple clamping, resulting in the symmetry of the inner V-groove of the paired half clamps exceeding the tolerance, affecting the fit of subsequent assembly; on the other hand, general-purpose fixtures are not stable enough for clamping irregularly shaped half clamps, and the groove dimension accuracy may decrease due to vibration during processing, especially in mass production, making it difficult to guarantee product consistency. Utility Model Content

[0005] To address the technical problems of cumbersome operation and large positioning errors in the existing technology of machining the inner V-groove of a pair of half clamps by single-piece clamping, this utility model provides a tooling for turning the inner V-groove of a pair of half clamps.

[0006] Therefore, the present invention provides the following technical solution:

[0007] A tooling for turning a pair of half clamps into an inner V-groove includes a clamping cylinder and an upper pressure block. The clamping cylinder has a clamping through hole along its axial direction. A tooling cylinder is coaxially provided at the front end of the clamping cylinder. A tooling hole is coaxially provided at the front end of the tooling cylinder. Lug grooves are provided on both sides of the end face of the tooling cylinder along the diameter of the tooling hole. The lug grooves are connected to the tooling hole. The upper pressure block is installed on the end face of the tooling cylinder corresponding to the position of each lug groove by an upper clamping bolt.

[0008] Furthermore, on the outer wall of the clamping cylinder, at the position corresponding to the tooling hole, a pair of side positioning bolts are installed through the clamping cylinder radially, and each pair of side positioning bolts is symmetrical along the diameter of the tooling hole.

[0009] Furthermore, an auxiliary pressure block is installed on the front end face of the tooling cylinder at the position corresponding to the tooling hole by means of an upper auxiliary clamping bolt.

[0010] Furthermore, a support block is installed on the outer wall of the tooling cylinder at the position corresponding to the ear slot, and the upper pressure block is installed on the support block by an upper clamping bolt.

[0011] Furthermore, the tooling cylinder has a circular groove on its axial bottom surface corresponding to the tooling hole.

[0012] Furthermore, the outer diameter of the tooling cylinder is larger than the outer diameter of the clamping cylinder.

[0013] Advantages and positive effects of this utility model:

[0014] By placing a pair of half clamps in the tooling hole, with the lugs at both ends of the two half clamps located in the corresponding lug slots, the two half clamps are limited. At the same time, the upper clamping bolts are used to press the lugs against the upper clamping block, thus fixing the two half clamps simultaneously. The tooling is installed on the lathe through the clamping through hole, and then the inner V-grooves of the two half clamps are machined. During the machining process, there is no need to repeatedly calibrate the position of the half clamps, making the operation simple, the positioning error small, the machining accuracy high, and the production efficiency high.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] This utility model provides a tooling for turning internal V-grooves in pairs of semi-clamps, such as... Figures 1-3 As shown, the device includes a clamping cylinder 7 and an upper pressure block 3. The clamping cylinder 7 has a clamping through hole 8 along its axial direction. A tooling cylinder 1 is coaxially mounted at the front end of the clamping cylinder 7, and the outer diameter of the tooling cylinder 1 is larger than that of the clamping cylinder 7. A tooling hole 9 is coaxially mounted at the front end of the tooling cylinder 1. Lug grooves 10 are symmetrically arranged on both sides of the end face of the tooling cylinder 1 along the diameter of the tooling hole 9, and the lug grooves 10 communicate with the tooling hole 9. A support block 2 is installed on the outer wall of the tooling cylinder 1 at a position corresponding to the lug groove 10. The upper pressure block 3 is mounted on the support block 2 by an upper clamping bolt 11.

[0022] On the outer wall of the clamping cylinder 7, corresponding to the tooling hole 9, pairs of side positioning bolts 5 are installed radially through the clamping cylinder 7. Both pairs of side positioning bolts 5 are symmetrical along the diameter of the tooling hole 9. The distance between adjacent side positioning bolts 5 is equal. On the front end face of the tooling cylinder 1, corresponding to the tooling hole 9, upper auxiliary clamping blocks 4 are installed via upper auxiliary clamping bolts 6. The two sets of upper auxiliary clamping bolts 6 and upper auxiliary clamping blocks 4 are symmetrical along the straight line containing the two upper clamping blocks 3. A circular groove 12 is provided on the axial bottom surface of the tooling cylinder 1 corresponding to the tooling hole 9.

[0023] Working principle: Place the pair of half clamps 13 into the tooling hole 9, with the bottom of the half clamp 13 engaging in the circular groove 12. The lugs 14 of the half clamp 13 are located in the lug groove 10. Tighten the upper clamping bolt 11 so that the upper pressure block 3 simultaneously presses onto the lugs 14 of the pair of half clamps 13. Tighten the side positioning bolt 5 so that the side positioning bolt 5 aligns from the side of the pair of half clamps 13 for clamping and fixing. Tighten the upper auxiliary clamping bolt 6 so that the upper auxiliary pressure block 4 presses onto the half clamp 13, completing the simultaneous installation of the pair of half clamps 13. Install the tooling on the lathe jaws through the clamping through hole 8 and turn the inner V-groove of the pair of half clamps 13. During the machining process, the inner V-groove of the pair of half clamps 13 is machined in one go, without the need for repeated calibration. The operation is simple, the positioning error is small, the machining accuracy is high, and the production efficiency is high.
