Description

Technical Field

[0001] This utility model mainly relates to the field of lathe processing equipment technology, specifically a bolt protection cover for a lathe workpiece fixing bracket. Background Technology

[0002] A bolt guard is a device used to protect bolts from external environmental influences (such as dust, chips, coolant, etc.) and to prevent accidental contact with the bolts by operators. It is typically installed on the workpiece holder of machining equipment (such as lathes and milling machines) to ensure bolt stability during machining, extend bolt life, and improve operational safety.

[0003] In existing lathe workpiece holder bolt protection covers, the installation and removal process usually requires the use of multiple tools and complex steps. For example, wrenches or other tools are needed to fix and loosen the protection cover, which not only increases the operation time but may also cause operator fatigue and affect work efficiency. Utility Model Content

[0004] This utility model mainly provides a bolt protection cover for a lathe workpiece fixing bracket to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A bolt protection cover for a lathe workpiece fixing bracket includes a fixing bracket and a protective cover. Multiple bolts are threaded to both sides of the fixing bracket, and connecting brackets are fixedly connected to both sides of the fixing bracket outside the bolts. A through groove is opened inside the connecting bracket, and multiple fixing mechanisms are provided on both sides of the through groove.

[0007] A connecting frame is fixedly installed at one end of the protective cover, and mounting blocks are fixedly connected to both sides of one end of the connecting frame.

[0008] Preferably, the number of fixing mechanisms is four, and every two fixing mechanisms form a group, with the two groups of fixing mechanisms equidistantly distributed on both sides of the through groove with the central axis as the reference.

[0009] Preferably, the fixing mechanism includes a fixing groove, a spring, and a locking block. Fixing grooves are provided on both sides of the through groove, and a spring is fixedly connected to one end of the fixing groove, and a locking block is fixedly connected to one end of the spring.

[0010] Preferably, the card block is inclined on both sides at one end, and the inclination angle of the inclined surface is 30 degrees.

[0011] Preferably, a limiting groove is provided above the fixing groove, a limiting block is fixedly connected to the top of the card block, and the limiting block is disposed inside the limiting groove.

[0012] Preferably, the two mounting blocks have grooves on one side, and the surface of the grooves has anti-slip textures, and the two grooves fit against the outside of the bolts.

[0013] Preferably, the mounting block has two slots on the side away from the groove, and the two slots are equidistantly distributed on its upper and lower sides with the horizontal central axis of the mounting block as a reference.

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

[0015] With the use of the fixing mechanism, during installation, simply align the mounting block with the through slot and gently push it in. The locking block will automatically engage with the slot under the action of the spring, thus fixing the protective cover. Similarly, during disassembly, pulling the protective cover will move the mounting block outward, and the locking block will automatically disengage from the slot, allowing the protective cover to be easily removed. This saves operation time, reduces wear and tear on the protective cover and fixing frame caused by frequent installation and disassembly, and extends the service life of the equipment. It eliminates the need for complicated tools or cumbersome steps, greatly shortening installation time and improving work efficiency.

[0016] The groove on the mounting block fits tightly against the bolt end, and the anti-slip texture on the groove surface significantly increases friction, effectively preventing the bolt from rotating or loosening during processing, improving the bolt's stability, and ensuring the workpiece is accurately fixed during processing.

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0025] Please refer to the appendix carefully. Figure 1-5A bolt protection cover for a lathe workpiece fixing bracket includes a fixing bracket 1 and a protective cover 2. Multiple bolts 3 are threaded onto both sides of the fixing bracket 1, with a total of four bolts 3, used to fix the fixing bracket 1 to the lathe. Connecting brackets 4 are fixedly connected to both sides of the fixing bracket 1 outside the bolts 3. A through groove 5 is formed inside the connecting bracket 4. Multiple fixing mechanisms 6 are provided on both sides of the through groove 5, with a total of four fixing mechanisms 6. Each pair of fixing mechanisms 6 forms a group, and the two groups of fixing mechanisms 6 are equidistantly distributed on both sides of the through groove 5 with the central axis as the reference. This symmetrical distribution ensures the stability and balance of the protective cover 2 during installation. Each fixing mechanism 6 includes a fixing groove 601, a spring 602, and a locking block 603. Fixing grooves 601 are formed on both sides of the through groove 5, and a spring 602 is fixedly connected to one end of each fixing groove 601, with a locking block 603 fixedly connected to the other end of each spring 602. The locking block 603 is inclined on both sides at one end, and the inclination angle of the inclined surface is 30 degrees. This allows the locking block 603 to move flexibly into the fixing groove 601 when subjected to external force, and to automatically pop out at the appropriate time through the elastic action of the spring 602, so as to quickly fix and release the protective cover 2. A limiting groove 8 is opened above the fixing groove 601, and a limiting block 9 is fixedly connected to the top of the locking block 603. The limiting block 9 is set inside the limiting groove 8, which further restricts the movement range of the locking block 603 and ensures that it moves stably in the fixing groove 601. A connecting frame 4 is fixedly installed at one end of the protective cover 2, and mounting blocks 7 are fixedly connected to both sides of one end of the connecting frame 4. A groove 10 is opened on one side of the two mounting blocks 7, and the surface of the groove 10 is provided with anti-slip texture 11. The use of anti-slip texture 11 significantly increases the friction with the outside of the bolt 3, effectively preventing the bolt 3 from loosening during processing. The two grooves 10 fit tightly against the outer side of the bolt 3, ensuring close contact between the mounting block 7 and the bolt 3. The mounting block 7 has two slots 12 on the side away from the grooves 10, and the two slots 12 are equidistantly distributed on its upper and lower sides with the transverse central axis of the mounting block 7 as a reference, for cooperating with the locking block 603 to achieve stable fixation of the protective cover 2.

[0026] The specific operation method of this utility model is as follows:

[0027] In use, first fix the bolt 3 to the fixing bracket 1, then push the mounting block 7 into the through groove 5. When pushing in, the locking block 603 will move into the fixing groove 601 and squeeze the spring 602. When the locking block 603 and the groove 12 are on the same vertical line, the locking block 603 will be locked into the groove 12 under the action of the spring 602, thus completing the installation of the protective cover 2. At the same time, the mounting block 7 fits the end of the bolt 3 inside the through groove 5. The anti-slip texture 11 on the surface of the groove 10 can increase the friction and prevent the bolt 3 from rotating or loosening. When it is necessary to remove the bolt 3, the protective cover 2 can be pulled, which will drive the mounting block 7 to move outward. Since both sides of one end of the locking block 603 are double trapezoidal, the locking block 603 will move under the action of the mounting block 7 and disengage from the groove 12, thus removing the protective cover 2, which facilitates the subsequent removal of the bolt 3.

[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
