Abstract
Description
Technical Field
[0001] The utility model belongs to a jig for processing the base of a stone or metal processing machine tool, in particular to a jig for processing and fixing the machine tool base. Background Art
[0002] When machining stone or metal on a machine tool, a turret and workpiece securing structures are typically installed on the machine tool base to facilitate turning, milling, drilling, and grinding operations. Therefore, the base must be machined for the appropriate mounting locations during assembly. However, due to the base's large size, securing it during machining is difficult. Consequently, manual processing is often required, resulting in inefficient machining and limited precision and speed. This wastes significant manpower and reduces efficiency. Utility Model Content
[0003] The purpose of the utility model is to provide a fixture for fixing a machine tool base that can solve at least one of the above problems.
[0004] According to one aspect of the utility model, a jig for fixing a machine tool base is provided, comprising a support seat, left and right clamping devices and upper and lower clamping devices, the left and right clamping devices and the upper and lower clamping devices being all arranged at the top end of the support seat, the left and right clamping devices comprising left and right clamping blocks, which can move left and right relative to the support seat, the upper and lower clamping devices comprising upper and lower clamping blocks, which can move up and down relative to the support seat.
[0005] The beneficial effects of this utility model are as follows: by providing left and right clamping devices and upper and lower clamping devices on the support base, when the machine tool base needs to be machined, the four corners of the machine tool base are fixed by the fixture. Specifically, the left and right clamping blocks limit the left and right position of the machine tool base, preventing it from moving left and right; and the upper and lower clamping blocks limit the upper and lower position of the machine tool base, preventing it from loosening up and down. As a result, the overall structure of the fixture is simple, and it can achieve the purpose of limiting the machine tool base, thereby facilitating machining of the machine tool base, saving labor, and improving processing efficiency.
[0006] In some embodiments, the left and right clamping devices further include a mounting plate and a first adjustment rod. The first adjustment rod is a screw. The bottom end of the mounting plate is fixed to the support base. The first adjustment rod passes through the mounting plate and is fixed to the left and right clamping blocks. The first adjustment rod and the mounting plate are threaded. Thus, the left and right positions of the left and right clamping blocks can be adjusted by the first adjustment rod, facilitating the tightening of the machine tool base and preventing loosening.
[0007] In some embodiments, the upper and lower clamping devices further include a second adjustment rod, one end of which is sleeved on the top of the support base, and the other end of which extends through the upper and lower clamping blocks. The other end of the second adjustment rod is sleeved with a nut that abuts against the upper end surfaces of the upper and lower clamping blocks. Thus, the upper and lower clamping blocks can be moved up and down on the second adjustment rod to clamp the machine tool base.
[0008] In some embodiments, the fixture for securing the machine tool base further includes a balancing block, which is fixed to the top of the support base, located on one side of the left and right clamping devices. One end of the upper and lower clamping blocks abuts the balancing block. Thus, the provision of the balancing block facilitates balanced force on both ends of the upper and lower clamping blocks when they press against the base, helping to maintain a horizontal position for the upper and lower clamping blocks, thereby enabling stable compression of the machine tool base.
[0009] In some embodiments, the mounting plate is fixed to the side wall of the support base, and the mounting plate is in an inverted T-shape, thereby facilitating improvement of the strength of the mounting plate.
[0010] In some embodiments, the upper and lower pressing blocks are square, thereby ensuring that the upper and lower pressing blocks are in stable contact with the contact surface of the machine tool base, increasing the contact area and facilitating more stable pressing.
[0011] In some embodiments, the front and rear sides of the support base are provided with reinforcing ribs, which extend from the bottom end to the top end of the support base. Thus, by providing the reinforcing ribs, the strength of the support base can be increased, and the stability of the support base can be improved.
[0012] In some embodiments, a base plate is provided at the bottom end of the support base. The base plate and the support base are integrally formed, with the front and rear ends of the base plate extending beyond the corresponding end surfaces of the support base. Thus, the base plate increases the contact area of the entire support base, further improving the stability of the support base and preventing it from tilting, thereby ensuring that each vertex of the base is firmly and securely pressed.
[0013] In some embodiments, the fixture for securing the machine tool base further includes a mounting plate with a slide groove formed thereon. The bottom end of the support base engages with the slide groove via a connector, allowing the support base to move along the slide groove. Thus, the slide groove allows for adjustment of the distance between the front and rear fixtures, facilitating adjustment based on the base length and improving applicability.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.
[0018] Reference Figure 1 and Figure 2 . A fixture for fixing a machine tool base includes a support base 1, left and right clamping devices 2, and upper and lower clamping devices 3. The left and right clamping devices 2 and the upper and lower clamping devices 3 are both arranged at the top of the support base 1. The left and right clamping devices 2 include left and right clamping blocks 21, which can move left and right relative to the support base 1. The upper and lower clamping devices 3 include upper and lower clamping blocks 31, which can move up and down relative to the support base 1.
[0019] When the fixture for fixing the machine tool base is used, the four fixtures correspond to the machine tool base (such as Figure 3 The machine tool base is placed on the upper end surface of the support base 1 at the four top corners of the machine tool base (as shown). The four support bases 1 are used to support and level the entire machine tool base. Subsequently, the left and right clamping blocks 21 of the left and right clamping devices 2 push against the side walls of the machine tool base to fix the left and right positions of the machine tool base. The upper and lower clamping blocks 31 are then pressed against the corresponding sides of the machine tool base, fixing the upper and lower positions of the machine tool base and preventing it from moving. This ensures the fixation of the machine tool base, facilitates machining of the base, saves a lot of manpower, saves time, and improves processing efficiency.
[0020] The left and right clamping devices 2 also include a mounting plate 22 and a first adjusting rod 23. The first adjusting rod 23 is a screw. The bottom end of the mounting plate 22 is fixed on the support seat 1. The first adjusting rod 23 passes through the mounting plate 22 and is fixed to the left and right clamping blocks 21. The first adjusting rod 23 is threadedly matched with the mounting plate 22.
[0021] Therefore, when the left and right clamping blocks 21 need to clamp the machine tool base or the machine tool base needs to be taken out, the first adjusting rod 23 is rotated. Since the mounting plate 22 is fixed on the support seat 1, the first adjusting rod 23 can move relative to the mounting plate 22, so that the left and right clamping blocks 21 fixed with the first adjusting rod 23 are close to or away from the machine tool base, meeting the corresponding usage requirements.
[0022] The upper and lower clamping device 3 also includes a second adjusting rod 32, one end of which is sleeved on the top of the support seat 1, and the other end extends after passing through the upper and lower clamping blocks 31. The other end of the second adjusting rod 32 is sleeved with a nut 33, and the nut 33 can abut against the upper end surface of the upper and lower clamping blocks 31. When the upper and lower clamping blocks 31 need to move upward, loosen the nut 33 so that there is a certain distance between the nut 33 and the upper and lower clamping blocks 31, and then move upward along the second adjusting rod 32 so that the upper and lower clamping blocks 31 leave the machine tool base, and then rotate the upper and lower clamping blocks 31 to a certain angle to facilitate the removal of the machine tool base. Conversely, when the upper and lower clamping blocks 31 need to press the machine tool base downward, move the upper and lower clamping blocks 31 downward; when they are moved downward into place, tighten the nut 33 so that the nut 33 can press the upper and lower clamping blocks 31 and fix them.
[0023] The fixture for fixing a machine tool base in the present invention further includes a balancing block 4, which is fixed to the top of the support base 1 and located on one side of the left and right clamping devices 2. One end of the upper and lower clamping blocks 31 abuts against the balancing block 4. The provision of the balancing block 4 facilitates the upper and lower clamping blocks 31 to press against the machine tool base with one end while the other end presses against the balancing block 4. This helps ensure the stability of the force applied to both ends of the upper and lower clamping blocks 31, thereby preventing the upper and lower clamping blocks 31 from tilting due to uneven force, and ensures that the upper and lower clamping blocks 31 can be firmly pressed against the machine tool base.
[0024] At the same time, in order to further improve the stability of the upper and lower pressing blocks 31 on the machine tool base, the upper and lower pressing blocks 31 are square in shape, thereby increasing the effective area.
[0025] The mounting plate 22 is fixed to the side wall of the support base 1 by bolts, and the mounting plate 22 is in the shape of an inverted T. Thus, the strength of the mounting plate 22 can be increased, which is conducive to improving the service life.
[0026] The front and rear sides of the support base 1 are provided with reinforcing ribs 11, which extend from the bottom end to the top end of the support base 1. The reinforcing ribs 11 and the support base 1 are an integrally formed structure, which can increase the support strength of the support base 1.
[0027] A bottom plate 5 is provided at the bottom end of the support base 1 . The bottom plate 5 and the support base 1 are an integrally formed structure, and the front and rear ends of the bottom plate 5 extend beyond the corresponding end surfaces of the support base 1 .
[0028] The fixture for fixing a machine tool base in the present invention further includes a mounting slide 6, which is provided with a slide groove 61. The bottom end of the support base 1 is engaged with the slide groove 61 via a connector 7, so that the support base 1 can move along the slide groove 61. The connector 7 includes a screw 71 and a clamping block 72. The cross section of the slide groove 61 is an inverted T-shape. The clamping block 72 is inserted from one end of the slide groove 61 to the lower large end of the slide groove 61. One end of the screw 71 with a nut is located on the base plate 5, and the other end passes through the base plate 5 and then downwardly engages with the clamping block 72 through a thread.
[0029] The upper and lower end surfaces of the block 72 abut against the upper and lower end surfaces at the lower end of the chute 61, so that the block 72 can only move along the length of the chute 61, and cannot move up and down. When the position of the support base 1 on the chute 61 needs to be adjusted, the screw 71 is loosened with external force to facilitate the movement of the block 72 and the support base 1 along the length of the chute 61. After moving into position, the screw 71 is tightened in the opposite direction, so that the screw 71 and the block 72 jointly press the base plate 5 and fix it to the corresponding position of the mounting slide 6, which is easy to adjust to meet different usage requirements.
[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
