Description

Technical Field

[0001] The utility model belongs to the technical field of bench vises, and in particular relates to a combined multi-purpose bench vise. Background Art

[0002] A bench vise is a general-purpose fixture commonly used to clamp workpieces. It is widely used in mechanical processing, assembly, maintenance and other fields. A traditional bench vise usually includes a fixed clamp body and a movable clamp body. The distance between the two clamp bodies is adjusted by rotating the lead screw to clamp the workpiece.

[0003] For example, a bench vise disclosed in the existing patent publication number CN211916572U adopts a side groove on the base, which is connected to the spherical groove, so that the universal ball can rotate from the side to the lower hemisphere, and the angle adjustment range is large, which has the effect of less limitation, more convenient and flexible use;

[0004] However, the existing bench vise design has certain limitations when clamping workpieces that are too long. Due to the limited width of the jaws, when the workpiece length exceeds a certain range, the traditional bench vise is difficult to provide stable support, causing the workpiece to easily shift or flip during processing, affecting the processing accuracy and operation safety. Therefore, it is necessary to propose a new type of bench vise. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0027] like Figure 1-5 As shown, a combined multi-purpose bench vise comprises a base frame 1, a fixed clamping plate 2 is fixed at one end of the base frame 1, a sliding clamping plate 3 is slidably connected to the top of the base frame 1, and a threaded rod 4 is rotatably connected to one end of the sliding clamping plate 3, and the threaded rod 4 is threadedly connected to the base frame 1;

[0028] The above structure is a common structure of a bench vise. By screwing the threaded rod 4, and then through the rotational connection between the threaded rod 4 and the sliding clamping plate 3, and through the threaded connection between the threaded rod 4 and the base frame 1, the threaded rod 4 can move forward and transmit the moving force to the sliding clamping plate 3. Through the sliding connection between the sliding clamping plate 3 and the base frame 1, the sliding clamping plate 3 can move forward and backward, and then the sliding clamping plate 3 can move toward the direction close to the fixed clamping plate 2. Through the mutual cooperation between the sliding clamping plate 3 and the fixed clamping plate 2, the workpiece is clamped. This type of bench vise is a common knowledge known to people in the relevant technical field, and will not be repeated here.

[0029] The fixed clamping plate 2 and the sliding clamping plate 3 are both installed with an extended clamping mechanism;

[0030] The extending clamping mechanism includes a first sliding rod 5 and a second sliding rod 6, both of which are made of metal, so that the first sliding rod 5 and the second sliding rod 6 will not be easily bent or damaged. The first sliding rod 5 and the second sliding rod 6 can be made of iron or other materials, and the first sliding rod 5 and the second sliding rod 6 are inserted into the fixed clamping plate 2 and the sliding clamping plate 3 and are symmetrically arranged, and the first sliding rod 5 and the second sliding rod 6 are respectively interference fit with the fixed clamping plate 2 and the sliding clamping plate 3. When the first sliding rod 5 and the second sliding rod 6 are inserted into the fixed clamping plate 2 or the sliding clamping plate 3, the interference fit can be used to prevent the first sliding rod 5 and the second sliding rod 6 from easily moving relative to the fixed clamping plate 2 and the sliding clamping plate 3. The second sliding rod 6 is inserted into the inner side of the first sliding rod 5, and the diameter of the second sliding rod 6 is smaller than that of the first sliding rod 5, so that the second sliding rod 6 can be inserted into the inner side of the first sliding rod 5;

[0031] A plurality of clamping blocks 7 are arranged on the outer sides of the second sliding rod 6 and the first sliding rod 5. The clamping blocks 7 on the fixed clamping plate 2 and the clamping blocks 7 on the sliding clamping plate 3 are arranged symmetrically. Through the arrangement of the clamping blocks 7, the clamping blocks 7 can clamp the protruding part of the workpiece. At least one limiting strip 17 is arranged on the outer sides of the second sliding rod 6 and the first sliding rod 5, and the limiting strip 17 is slidably connected with the clamping blocks 7. Through this arrangement, when the clamping blocks 7 are installed, they can be restricted by the limiting strip 17 without reversal. The outer surface of the clamping blocks 7 is provided with a side cushion. Through this arrangement, the clamping blocks 7 can reduce damage to the workpiece when clamping the workpiece.

[0032] A clamping structure is provided between the first sliding rod 5 and the second sliding rod 6 , and the clamping structure is used to clamp the first sliding rod 5 and the second sliding rod 6 .

[0033] As mentioned above, when clamping a longer workpiece, the first sliding rod 5 and the second sliding rod 6 can be installed in the fixed clamping plate 2 and the sliding clamping plate 3 respectively, and the second sliding rod 6 is inserted into the first sliding rod 5. After adjusting the specific length, when the fixed clamping plate 2 and the sliding clamping plate 3 are close to each other, the two groups of clamping blocks 7 are also close to each other to clamp the overly long workpiece. Therefore, through this combination method, the workpiece can be clamped. When it is not necessary to clamp a too long workpiece, the first sliding rod 5 and the second sliding rod 6 can be disassembled.

[0034] See attached Figure 2-4The clamping structure includes a mounting groove 9 arranged on the inner side of the first sliding rod 5, the second sliding rod 6 is inserted into the inner side of the mounting groove 9, a plurality of first clamping blocks 8 are evenly arranged on the outer side of the second sliding rod 6, and a second clamping block 10 corresponding to the first clamping block 8 is arranged on the inner wall of the mounting groove 9. The first clamping block 8 and the second clamping block 10 are both made of flexible materials. Through this arrangement, when the first clamping block 8 and the second clamping block 10 are close to each other and contact each other front and back, the contact effect can be better;

[0035] The second sliding rod 6 is fixed with a mounting post 16 at one end close to the first sliding rod 5, and a torsion spring 11 is sleeved on the outer side of the mounting post 16. The mounting post 16 is used to install the torsion spring 11 so that it will not twist forward and backward when deformed. The second sliding rod 6 is close to the first sliding rod 5 and is symmetrically provided with a mounting plate 13 and a sliding sheet 14 at one end and located on the outer side of the mounting post 16. The mounting plate 13 is fixedly connected to the second sliding rod 6, and the sliding sheet 14 is slidably connected to the second sliding rod 6 through a sliding groove 12. The length of the inner diameter of the sliding groove 12 is slightly longer than the length of the first clamping block 8 or the second clamping block 10. Therefore, when the second sliding rod 6 is twisted, it will not be twisted excessively to cause the first clamping block 8 and the second clamping block 10 to not align.

[0036] One end of the torsion spring 11 is fixedly connected to the mounting plate 13, and the end of the torsion spring 11 away from the mounting plate 13 is fixedly connected to the sliding sheet 14. A sliding bar 15 is fixed to the side of the sliding sheet 14 away from the torsion spring 11, and the sliding bar 15 is slidably connected to the inner wall of the mounting groove 9. When the sliding bar 15 slides on the inner wall of the mounting groove 9, it can avoid the second clamping block 10 inside the mounting groove 9, so as to avoid interfering with the normal clamping or twisting state of the first clamping block 8 and the second clamping block 10;

[0037] When adjusting the distance between the first sliding rod 5 and the second sliding rod 6, the second sliding rod 6 can be twisted, so that the second sliding rod 6 drives the first clamping block 8 to twist, and the front and rear clamping connection with the second clamping block 10 is released. At this time, the torsion spring 11 follows the twisting and drives the mounting plate 13 to twist, while the sliding sheet 14 and the sliding bar 15 can not follow the twisting of the second sliding rod 6 through the sliding connection with the mounting groove 9. At this time, the second sliding rod 6 can be pulled back and forth to adjust the length between the first sliding rod 5. After the adjustment is completed, the second sliding rod 6 is released. The second sliding rod 6 is set by the torsion spring 11, so that the torsion spring 11 can drive the second sliding rod 6 to reset, thereby realizing the state that the first clamping block 8 and the second clamping block 10 are clamped to each other. The clamping structure can also be achieved by interference fit.

[0038] See attached Figure 5, magnetic blocks 18 are arranged at intervals on the outer sides of the second sliding rod 6 and the first sliding rod 5, and a plurality of clamping blocks 7 are arranged on the outer sides of the magnetic blocks 18, and magnets corresponding to the magnetic blocks 18 are arranged on the inner sides of the clamping blocks 7, and the magnetism of the outer side of the magnetic block 18 is opposite to the magnetism of the inner side of the clamping block 7, for example, the magnetism of the inner side of the clamping block 7 is the N pole, and the magnetism of the outer side of the magnetic block 18 is the S pole, and vice versa;

[0039] The multiple clamping blocks 7 can also be an integral whole. Similarly, the magnetic block 18 can occupy the entire first sliding rod 5 and the second sliding rod 6, and the multiple clamping blocks 7 can be installed without gaps, so as to better clamp the workpiece. The clamping blocks 7 can be of various specifications, such as arc shape, etc., and can clamp workpieces of various specifications and shapes, thereby realizing multiple uses.

[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
