Description

Technical Field

[0001] This utility model relates to the field of tailless thread sleeve processing technology, and in particular to a tailless thread sleeve guide angle grinding device. Background Technology

[0002] Tailless thread inserts are specially designed thread fastening reinforcement elements, an upgraded type of wire thread inserts (threaded sleeves). Their core features are the absence of an installation shank and an efficient installation method. Tailless thread inserts, also known as "shankless wire thread inserts," are made from high-precision stainless steel diamond-shaped wire coils.

[0003] The spring-shaped helix, with hook-shaped grooves at both ends, allows for direct screwing into the threaded hole without needing to distinguish direction during installation, using a special tool. The diamond-shaped stainless steel wire is key to the performance of the tailless thread insert, primarily contributing to its mechanical properties and installation reliability. During production, the wire needs to be stamped into a diamond-shaped cross-section. To facilitate insert installation, a guide angle needs to be created on the tailless thread insert, requiring a tailless thread insert guide angle grinding device.

[0004] A rotary workstation device and machine tool for thread sleeve processing, disclosed in Chinese patent document CN113770458A, includes a base, a rotary worktable, and multiple workstations. The base has a receiving cavity in its middle section, within which a support shaft is housed. The rotary worktable is mounted on the support shaft via a turntable bearing and is rotatable relative to the support shaft. Multiple workstations are arranged on the rotary worktable, distributed circumferentially. This invention effectively solves the cumbersome problems of multiple processes and multiple machine tools in current thread sleeve processing by setting multiple workstations and performing processing simultaneously. It improves the precision, stability, and efficiency of thread sleeve processing. It has wide applications, extending to the rough and finish machining of other similar parts, thus expanding the machine tool's range of use. However, the rotary workstation device and machine tool for thread sleeve processing lack a guide angle on the tailless thread sleeve, making installation difficult.

[0005] To address the shortcomings of the existing technology, providing a tailless threaded sleeve guide angle grinding device is a problem worthy of research. Utility Model Content

[0006] The purpose of this invention is to overcome the disadvantage of not having a guide angle on the tailless thread insert, which makes it difficult to install the threaded sleeve. It provides a tailless thread insert guide angle grinding device, which achieves the technical effect of efficiently opening the guide angle on the tailless thread insert.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A tailless threaded sleeve guide angle grinding device includes a guide angle grinding table, a motor disposed at the center of the top of the guide angle grinding table, clamping mechanisms disposed on the four sides of the motor output end, a loading station disposed on one side of the top of the guide angle grinding table, a unloading station disposed on one side of the loading station, and a grinding station disposed between the loading station and the unloading station.

[0009] The motor is a stepper motor. The clamping mechanism at the output end of the motor has an adjacent included angle of 90 degrees. The angle of a single rotation of the motor is 90 degrees. The positions of the four clamping mechanisms correspond to the positions of the loading station, the unloading station, and the two grinding stations, respectively. By setting a click-driven clamping mechanism at the center of the guide angle grinding table, it can drive the tailless thread sleeve that needs to be ground to rotate and switch processing stations, so as to realize the efficient completion of the grinding process of the tailless thread sleeve.

[0010] A foot pedal is provided below one side of the guide angle grinding table, and the foot pedal is located on one side of the loading station.

[0011] The foot pedal is electrically connected to the motor, the loading station, the unloading station, and the grinding station. When the foot pedal is stepped on, the motor drives the clamping mechanism to rotate 90 degrees, and the grinding station completes one grinding process for the tailless thread sleeve. By setting a foot pedal on one side of the loading station, when grinding the guide angle of the tailless thread sleeve, the operator puts the tailless thread sleeve to be processed on the corresponding clamping mechanism of the loading station. Each time the foot pedal is stepped on, the clamped tailless thread sleeve can be rotated 90 degrees and processed in one step, and the loading station is freed up to facilitate the installation of new tailless thread sleeves to be processed.

[0012] The clamping mechanism includes a support arm and a mechanical claw disposed at the end of the support arm;

[0013] The gripping part of the mechanical claw is adapted to the shape of the tailless thread sleeve being processed. By setting a support arm with a mechanical claw on the motor output end, it can clamp and fix the tailless thread sleeve, making it convenient to transfer and grind it. After processing is completed, the clamping is released from the unloading station to complete the unloading.

[0014] The two grinding stations grind the tailless thread sleeve in opposite directions. By grinding both sides of the tailless thread sleeve in opposite directions, the tailless thread sleeve can be ground in all directions, thus completing the grinding of the tailless thread sleeve. This avoids the tailless thread sleeve being clamped in a way that makes the direction unadjustable, which could lead to insufficient local processing.

[0015] The unloading station includes a receiving slide on one side of the top of the guide angle grinding table and a receiving box on one side below the guide angle grinding table.

[0016] The receiving slide is inclined, with one top end located below the clamped tailless threaded sleeve and the other bottom end located above the receiving box. By setting an inclined receiving slide on one side of the guide angle grinding table, the tailless threaded sleeve released from the clamping mechanism is received and concentrated along the inclined surface to the receiving box, thus allowing the clamping mechanism to be in an idle state, facilitating reloading and achieving continuous and efficient grinding of the tailless threaded sleeve.

[0017] A control terminal is installed at one corner of the top of the guide angle grinding table. The control terminal is electrically connected to the motor and the grinding station. The electrical components of the grinding equipment are controlled and integrated through the control terminal, and the semi-automatic control of the entire grinding equipment is realized according to the signal output by the foot pedal.

[0018] Positive and beneficial effects:

[0019] 1. The tailless thread sleeve guide angle grinding equipment is equipped with a foot pedal on one side of the loading station. When grinding the guide angle of the tailless thread sleeve, the operator puts the tailless thread sleeve to be processed on the corresponding clamping mechanism of the loading station. Each time the foot pedal is stepped, the clamped tailless thread sleeve can be rotated 90 degrees and processed for one step, and the loading station is cleared to facilitate the installation of new tailless thread sleeves to be processed.

[0020] 2. This tailless thread sleeve guide angle grinding equipment has two grinding stations in opposite directions to grind both sides of the tailless thread sleeve being processed, completing the all-round grinding of the tailless thread sleeve and avoiding the situation where the tailless thread sleeve is clamped and the direction cannot be adjusted, resulting in insufficient local processing.

[0021] 3. The tailless threaded sleeve guide angle grinding equipment has a control terminal that integrates and controls the electrical components of the grinding equipment, and achieves semi-automatic control of the entire grinding equipment based on the signal output from the foot pedal.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0029] like Figures 1 to 5 As shown, a tailless threaded sleeve guide angle grinding device includes a guide angle grinding table 1, characterized in that: it also includes a motor 2 disposed at the top center of the guide angle grinding table 1, a clamping mechanism 3 disposed on the four sides of the output end of the motor 2, a loading station 4 disposed on one side of the top of the guide angle grinding table 1, a unloading station 5 disposed on one side of the loading station 4, and a grinding station 6 disposed between the loading station 4 and the unloading station 5.

[0030] like Figures 1 to 3 As shown, motor 2 is a stepper motor. The clamping mechanism 3 at the output end of motor 2 has an adjacent included angle of 90 degrees. The angle of a single rotation of motor 2 is 90 degrees. The positions of the four clamping mechanisms 3 correspond to the positions of the loading station 4, the unloading station 5, and the two grinding stations 6, respectively. By setting the clamping mechanism 3 driven by the click 2 at the center of the guide angle grinding table 1, it can drive the tailless thread sleeve that needs to be ground to rotate and switch the processing station, so as to realize the efficient completion of the grinding process of the tailless thread sleeve.

[0031] like Figures 4 to 5 As shown, a foot pedal 7 is provided below one side of the guide angle grinding table 1, and the foot pedal 7 is located on one side of the loading station 4.

[0032] The foot pedal 7 is electrically connected to the motor 2, the loading station 4, the unloading station 5, and the grinding station 6. When the foot pedal 7 is stepped on, the motor 2 drives the clamping mechanism 3 to rotate 90 degrees, and the grinding station 6 completes one grinding process for the tailless thread sleeve. By setting the foot pedal 7 on one side of the loading station 4, when grinding the guide angle of the tailless thread sleeve, the operator puts the tailless thread sleeve to be processed on the corresponding clamping mechanism 3 of the loading station 4. Each time the foot pedal 7 is stepped on, the clamped tailless thread sleeve can be rotated 90 degrees and processed in one step, and the loading station 4 is freed up to facilitate the installation of new tailless thread sleeves to be processed. Example 2

[0033] like Figures 2 to 5 As shown, the clamping mechanism 3 includes a support arm 301 and a mechanical claw 302 disposed at the end of the support arm 301;

[0034] The clamping part of the mechanical claw 302 is adapted to the shape of the tailless thread sleeve to be processed. By setting a support arm 301 with mechanical claw 302 on the output end of the motor 2, the tailless thread sleeve can be clamped and fixed, making it convenient to transfer and grind it. After processing is completed, the clamping is released from the unloading station 5 to complete the unloading.

[0035] like Figures 1 to 4 As shown, the two grinding stations 6 grind the tailless thread sleeve in opposite directions. By grinding both sides of the tailless thread sleeve being processed through the two grinding stations 6 in opposite directions, the tailless thread sleeve is ground in all directions, thus completing the all-round grinding of the tailless thread sleeve. This avoids the tailless thread sleeve being clamped in a way that makes the direction unadjustable, which could lead to insufficient local processing. Example 3

[0036] like Figures 1 to 4 As shown, the unloading station 5 includes a receiving slide 501 located on one side of the top of the guide angle grinding table 1, and a receiving box 502 located on one side below the guide angle grinding table 1.

[0037] like Figures 1 to 4 As shown, the receiving slide 501 is in an inclined state. One end of the receiving slide 501 is located below the clamped tailless thread sleeve, and the other end of the receiving slide 501 is located above the receiving box 502. By setting an inclined receiving slide 501 on one side of the guide angle grinding table 1, the tailless thread sleeve released from the clamping mechanism 3 is received and concentrated along the inclined surface to the receiving box 502, so that the clamping mechanism 3 is in an idle state, which facilitates the re-loading of materials and realizes continuous and efficient grinding of the tailless thread sleeve.

[0038] like Figures 1 to 4 As shown, a control terminal 8 is installed at one corner of the top of the guide angle grinding table 1. The control terminal 8 is electrically connected to the motor 2 and the grinding station 6. The electrical components of the grinding equipment are controlled and integrated through the control terminal 8, and the semi-automatic control of the entire grinding equipment is realized according to the signal output by the foot pedal 7.

[0039] The working principle of this utility model is as follows:

[0040] S1. The operator places the tailless screw set to be processed onto the clamping mechanism 3 corresponding to the loading station 4.

[0041] S2. Each time the foot pedal 7 is stepped, the clamped tailless thread sleeve will rotate 90 degrees and perform one process, and the loading station 4 will be freed up to facilitate the installation of new tailless thread sleeves to be processed.

[0042] S3. Two grinding stations in opposite directions 6 grind both sides of the tailless threaded sleeve to complete the all-round grinding of the tailless threaded sleeve.

[0043] S4. The receiving slide 501 receives the tailless threaded sleeve that has been released from clamping by the clamping mechanism 3, and gathers it along the inclined surface to the receiving box 502.

[0044] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
