[0036] On the bottom plate 1, a waist-shaped countersunk hole can be opened in the bottom plate 1, so as to facilitate the bolt connection to the workbench of the machine tool, and at the same time, it does not affect the adjustment caused by the table operation.
[0037] On the base plate 1, the base plate 1 is provided with a positioning and clamping device and a pressing device.
[0038] The positioning and pressing device has not only the horizontal positioning function, but also the vertical positioning function and the fixing function of the left box body, while the pressing device only has the vertical positioning function and the fixing function of the left box body.

The distance between the left rear support pin 6 and the right rear positioning pin 4 is greater than the distance between the left front positioning pin 2 and the right front support pin 8.
[0041] In summary, it is easy to understand that in this embodiment, by setting the base plate 1, a mounting base of the tooling is formed, which facilitates fixing the tooling on the machine table of the machine tool, thereby forming a stable and consistent positional relationship, improving machining accuracy and achieving good dimensional consistency.
[0042] It is easy to understand that, by setting the positioning and clamping device and the pressing device, this embodiment enables a part of the clamping structure to have not only the clamping and fixing function but also the positioning function. Furthermore, on the basis of satisfying the positioning and fixing requirements, the total number of positioning points and fastening points is reduced, which is beneficial to reduce the occupied space, reduce the number of parts, reduce the manufacturing cost, and at the same time, reduce the obstruction of the left box body, making it easier to take and put materials.
[0043] It is easy to understand that in this embodiment, a positioning and clamping device is provided so that the positioning and clamping device includes a left front positioning and clamping mechanism and a right rear positioning and clamping mechanism, and the left front positioning and clamping mechanism includes a left front positioning pin 2 and a left front clamping block 3, and the left front positioning pin 2 and the left front clamping block 3 cooperate to position and clamp and fix the left front part of the left box body, and the right rear positioning and clamping mechanism includes a right rear positioning pin 4 and a right rear clamping block 5, and the right rear positioning pin 4 and the right rear clamping block 5 cooperate to position and clamp and fix the right rear part of the left box body. Therefore, on the basis of meeting the positioning and fixing requirements, the distance between the left front positioning pin 2 and the right rear positioning pin 4 is increased, the positioning accuracy is improved, the occupied space is not increased, and it is helpful to adopt a smaller-sized base plate 1 to reduce the manufacturing cost.
[0044] It is easy to understand that in this embodiment, a pressing device is provided so that the pressing device includes a left rear pressing mechanism and a right front pressing mechanism. The left rear pressing mechanism includes a left rear support pin 6 and a left rear clamping block 7. The left rear support pin 6 and the left rear clamping block 7 clamp and fix the left rear part of the left box body. The right front pressing mechanism includes a right front support pin 8 and a right front clamping block 9. The right front support pin 8 and the right front clamping block 9 clamp and fix the right front part of the left box body. The positioning pressing device and the pressing device cooperate to achieve four-point fixation of the left box body, thereby improving the stability of the fixation, reducing the vibration during machining, and ensuring the machining quality.
[0045] It is easy to understand that this embodiment makes the distance between the left rear support pin 6 and the right rear positioning pin 4 greater than the distance between the left front positioning pin 2 and the right front support pin 8. On the one hand, it is convenient for the operator to visually confirm the positions of the left front positioning pin 2 and the right rear positioning pin 4, and to confirm whether the left box body is placed in place. On the other hand, it is convenient for the operator to take and put materials in a horizontal or inclined direction, replacing the original lifting, translation and lowering loading method. In particular, it reduces the lifting stroke of the left box body, reduces the workload of taking and putting materials, reduces the difficulty of taking and putting materials, and thus shortens the time for taking and putting materials, shortens the machining cycle, and improves production efficiency.

[0047] In some specific embodiments of the present invention, the left front positioning pin 2 and the right rear positioning pin 4 may include a supporting surface and a positioning cone on the supporting surface, so that the supporting surface is used for pressing and the positioning cone is used for horizontal positioning.
[0048] In some specific embodiments of the present invention, the left front clamping block 3, the right rear clamping block 5, the left rear clamping block 7 and the right front clamping block 9 can include copper pads to gently contact the left box body, which helps to reduce vibration and prevent the left box body from being crushed.
[0049] In some specific embodiments of the present invention, the left front clamping block 3, the right rear clamping block 5, the left rear clamping block 7 and the right front clamping block 9 can be connected with adjustment bolts, so as to adjust the clamping angle so that the surface of the clamping block fits the left box body to avoid point contact.
[0050] In some specific embodiments of the present invention, the bottom plate 1 may be provided with a limiting device, which includes a front limiting block 10 , a left limiting block 11 and a right limiting block 12 .
[0051] It is easy to understand that, by providing the front limit block 10, the present embodiment can prevent the left box body from moving forward and touching the left front pressing block 3 and the right front pressing block 9, thereby reducing the probability of the left box body being damaged.
[0052] It is easy to understand that this embodiment, by providing the left limit block 11 and the right limit block 12, also facilitates centering of the left box body, avoids left-right deviation and touching the left rear clamping block 7 and the right rear clamping block 5, and further reduces the probability of damage to the left box body.
[0053] In some specific embodiments of the present invention, the front limit block 10, the left limit block 11 and the right limit block 12 can be connected with mounting columns, thereby reducing the material used for the front limit block 10, the left limit block 11 and the right limit block 12 and reducing the manufacturing cost.
[0054] In some specific embodiments of the present invention, the front limit block 10, the left limit block 11 and the right limit block 12 can be made of plastic to reduce damage caused by wear.
[0055] In some specific embodiments of the present invention, the front limit block 10, the left limit block 11 and the right limit block 12 may have guiding inclined surfaces or curved surfaces to facilitate the left box to fall to an accurate position.
[0056] In some specific embodiments of the present invention, the front limiting block 10 may have a limiting recess facing backward.
[0057] It is easy to understand that, in this embodiment, by providing the limiting recess, the left box body can be accurately limited in the left and right directions, thereby improving the limiting accuracy and facilitating the holes of the left box body to be fitted onto the left front positioning pin 2 and the right rear positioning pin 4.
[0058] In some specific embodiments of the present invention, the left limit block 11 can be located between the left front positioning pin 2 and the left rear supporting pin 6 , and the left limit block 11 is arranged close to the left rear supporting pin 6 .
[0059] It is easy to understand that in this embodiment, the left limit block 11 is located between the left front positioning pin 2 and the left rear support pin 6. The left limit block 11 is set close to the left rear support pin 6, and the corresponding position of the left box body is also set close to the left rear support pin 6, which is convenient for limiting the overall shape of the left box body in the initial state, reducing the probability of reverse installation, and avoiding the left box body from touching the left rear clamping block 7 first.
[0060] In some specific embodiments of the present invention, the right limit block 12 can be located between the right front support pin 8 and the right rear positioning pin 4 , and the right limit block 12 is arranged close to the right front support pin 8 .
[0061] It is easy to understand that this embodiment improves the position of the right limit block 12 to prevent the right limit block 12 from preferentially touching the left box body and affecting the loading, especially to avoid affecting the operation of inserting the right rear positioning pin 4 into the hole on the left box body.
[0062] Reference Figure 2 In some specific embodiments of the present invention, the left rear support pin 6 may include two parallel side walls arranged left and right.
[0063] It is easy to understand that, in this embodiment, by making the left rear support pin 6 include two parallel side walls arranged left and right, the space occupied by the left rear support pin 6 is minimized, and the difficulty of arranging the left rear clamping block 7 is reduced.
[0064] In some specific embodiments of the present invention, the left rear pressing block 7 can be located on the left side of the left rear supporting pin 6 , and the remaining pressing blocks are arranged toward the four corners of the bottom plate 1 .
[0065] It is easy to understand that this embodiment reduces obstruction to human hands by locating the left rear clamping block 7 on the left side of the left rear support pin 6, making it convenient for the left hand to push the left box body above the tooling without touching the left rear clamping block 7 and the corresponding cylinder, thereby not affecting the material taking and releasing operations. The remaining clamping blocks are arranged toward the four corners of the base plate 1, which is conducive to the rational use of the effective space of the base plate 1, reduces the occupied space, and helps to maintain the miniaturization of the base plate 1.
