Description

Technical Field

[0001] This utility model relates to tooling, and more particularly to a platform-type tooling for fixing workpieces. Background Technology

[0002] Tooling is generally used to clamp and fix workpieces, and to support drilling, milling, and other machining operations. Existing tooling typically uses a T-slot platform and multiple sets of fixtures. The fixtures include bolts, nuts for the bolts, and clamping blocks fitted onto the bolts. The bolt nuts can only move laterally and vertically within the T-slots. Rotating the nuts causes the clamping blocks to engage with the T-slot platform, clamping and fixing the workpiece. During machining, a considerable amount of debris falls into the platform and into the T-slots. While debris on the platform is relatively easy to clean, debris in the T-slots can affect the sliding of the bolts within the T-slots. A problem with existing tooling is that cleaning debris from the T-slots is relatively inconvenient. Utility Model Content

[0003] This application provides a platform-type tooling for fixing workpieces, which can solve the problems mentioned in the background art.

[0004] This application provides a platform-type fixture for fixing a workpiece, comprising:

[0005] The T-slot platform has multiple horizontal T-slots arranged side by side on the table, as well as two debris troughs; the two debris troughs divide each horizontal T-slot into a middle working area and storage areas at both ends.

[0006] Multiple clamps, each clamp including: a bolt, a nut for the bolt, and a pressure block fitted onto the bolt; the nut of the bolt can only move laterally and vertically within the transverse T-slot; the bottom surface of the nut also has a deformable layer that can be squeezed and deformed, the deformable layer being used to allow a gap between the top surface of the nut and the inner top wall of the transverse T-slot in the clamped state.

[0007] In some embodiments, the T-slot platform includes:

[0008] The first part is used to provide the working area for the transverse T-slot and the two debris troughs;

[0009] Two second sections are provided for the storage area of ​​the transverse T-slots; the connection position of the first section can be adjusted laterally to allow the storage area and the work area to switch between being separate and connected.

[0010] In some embodiments, the bottom plate of the debris trough is slidably connected to the T-shaped groove platform, and an elastic element or magnet is provided between the two to keep the bottom plate closed.

[0011] In some embodiments, the clamp further includes: an abutment block; the abutment block is fitted onto the bolt below the pressure block; the bolt is provided with a smooth section for the abutment block to fit into and for restricting its rotation.

[0012] In some implementations, the height of the smooth section is greater than the thickness of the abutting block, and the excess portion is used to allow the pressure block to fit in and to restrict its rotation.

[0013] In summary, this application discloses a platform-type fixture for fixing workpieces, comprising a T-slot platform and multiple clamps. When fixing the workpiece, a suitable clamp is selected from two sets of clamps and moved from the storage area to the working area, ensuring that there is one clamp in the working area of ​​each transverse T-slot. After machining, all clamps are loosened, the workpiece is removed, and each clamp slides back and forth along the working area, pushing debris from the working area into the corresponding debris groove. After cleaning the debris from the working area, these clamps are moved back to the corresponding storage area. The beneficial effect is that it facilitates the cleaning of debris from the transverse T-slots. Attached Figure Description

[0024] Please see Figure 1 and Figure 4 A platform-type fixture for fixing workpieces includes a T-slot platform 1 and multiple clamps 2.

[0025] The T-shaped groove platform 1 has multiple T-shaped grooves arranged side by side on its surface. The T-shaped grooves face outwards horizontally and are designated as horizontal T-shaped grooves 1c. The T-shaped grooves include a wider first groove 1c1 and a narrower second groove 1c2. The second groove 1c2 is above the first groove 1c1 and connects the first groove 1c1 with the outside world above the platform.

[0026] The T-shaped slot platform 1 also has two debris slots 1d on its surface. These two debris slots 1d divide each transverse T-shaped slot 1c into a middle working area 1c3 and storage areas 1c4 at both ends. In other words, the two debris slots 1d are located on opposite sides of the horizontal surface of the platform.

[0027] Multiple fixtures 2 can be used with T-slots to fix the workpiece on the T-slot platform 1.

[0028] More specifically, the number of fixtures 2 is twice the number of transverse T-slots 1c. Initially, they can be placed in the storage areas 1c4 at both ends of these transverse T-slots 1c. The workpiece to be fixed is placed in the middle of the table, and all the fixtures 2 are divided into two groups, which are placed on both sides of the workpiece. The appropriate fixture 2 is selected from these two groups and moved from the storage area 1c4 to the working area 1c3 to fix the workpiece on the T-slot platform 1.

[0029] Please see Figure 2The clamp 2 includes a bolt 2a, a nut 2b that matches the bolt 2a, and a pressure block 2c fitted onto the bolt 2a. The nut of the bolt 2a can only move laterally and vertically within the transverse T-slot 1c. More specifically, the nut can be square, with the same width as the wider first slot 1c1 in the transverse T-slot 1c.

[0030] In other words, the fixture 2 fixes the workpiece in the following way: adjust the position of the nut 2b according to the height of the workpiece; lift the pressure block 2c so that the pressure block 2c is higher than the workpiece; move the fixture 2 so that the pressure block 2c coincides with the edge of the workpiece; rotate the nut 2b, the nut of the bolt 2a first abuts against the inner top wall of the transverse T-slot 1c, and then the nut 2b moves down until the nut 2b presses the pressure block 2c, thereby engaging with the table to press and fix the workpiece.

[0031] The bottom surface of the nut also has a deformable layer 2a1 that can be compressed and deformed, such as a layer of sponge. The thickness of the deformable layer 2a1 plus the thickness of the nut can match the thickness of the first groove 1c1. The function of the deformable layer 2a1 is: when the clamp 2 is in the loose state, the deformable layer 2a1 is placed on the inner bottom wall of the transverse T-groove 1c. The weight of the bolt 2a acts on the deformable layer 2a1, causing the deformable layer 2a1 to be compressed and deformed, thereby creating a gap between the top surface of the nut and the inner top wall of the transverse T-groove 1c.

[0032] When the workpiece is fixed by the fixture 2, select a suitable fixture 2 from the two sets of fixtures 2 and move it from the storage area 1c4 to the working area 1c3, so that there is a fixture 2 on the working area 1c3 of each transverse T-slot 1c. After processing, loosen all the fixtures 2, remove the workpiece, and let each fixture 2 slide back and forth along the working area 1c3 to push the debris in the working area 1c3 into the corresponding debris groove 1d. After cleaning the debris in the working area 1c3, move these fixtures 2 back from the working area 1c3 to the corresponding storage area 1c4. When the debris in the debris groove 1d reaches a certain amount, it can be vacuumed away.

[0033] Please see Figure 3 In some embodiments, the T-slot platform 1 includes a first portion 1a and two second portions 1b. The first portion 1a is used to provide the working area 1c3 of the transverse T-slot 1c and two debris troughs 1d. The two second portions 1b are used to provide the storage area 1c4 of the transverse T-slot 1c. The two second portions 1b can also adjust the connection position of the first portion 1a laterally. More specifically, the second portions 1b can be slidably connected to the first portion 1a with damping. By adjusting the position of the second portions 1b relative to the first portion 1a, the storage area 1c4 and the working area 1c3 can be switched between being separate and connected.

[0034] When performing the actions described above, such as "selecting appropriate clamps 2 from the two sets of clamps 2 and moving them from storage area 1c4 to working area 1c3" and "moving these clamps 2 from working area 1c3 back to the corresponding storage area 1c4," the storage area 1c4 and working area 1c3 can be switched to be connected, making it easier for the clamps 2 to move between them. When performing the action described above, such as "sliding each clamp 2 back and forth along working area 1c3 to push the debris in working area 1c3 into the corresponding debris groove 1d," the storage area 1c4 and working area 1c3 are first switched to be separated, without affecting the entry of debris into the debris groove 1d.

[0035] Please see Figure 4 In some embodiments, the bottom plate 1d1 of the debris groove 1d is slidably connected to the T-shaped groove platform 1, and an elastic element or magnet 1e1 is provided between them to keep the bottom plate 1d1 closed. More specifically, connecting posts 1d2 can be fixedly connected to both sides of the bottom plate 1d1 in the lateral direction, and the top of the connecting post 1d2 has a cylindrical slider 1d3 with a larger diameter; the bottom surface of the T-shaped groove platform 1 has two holes 1e for the cylindrical slider 1d3 to slide, and the bottom end of the holes 1e is fixedly connected to a linear bearing 1d4 for the connecting post 1d2 to slide. When using an elastic element, the elastic element can be a compression spring, sleeved on the connecting post 1d2, with its two ends abutting against the cylindrical slider 1d3 and the linear bearing 1d4, respectively. When using a magnet 1e1, the magnet 1e1 is installed at the top of the hole 1e, and the cylindrical slider 1d3 can be attracted by the magnet 1e1.

[0036] When the debris in the debris groove 1d reaches a certain amount, the base plate 1d1 can be manually moved down to the lower limit position and held in that position by overcoming the elastic element or the magnet 1e1, so that the debris can leak out from the bottom of the debris groove 1d.

[0037] Please see Figure 5 In some embodiments, the clamp 2 further includes an abutment block 2d. The abutment block 2d is fitted onto the bolt 2a, below the pressure block 2c. The bolt 2a has a smooth section 2a2 for the abutment block 2d to fit into and for restricting its rotation. More specifically, the smooth section 2a2 may be square, and the abutment block 2d is elongated with a waist-shaped through groove for the smooth section 2a2 to enter.

[0038] When fixture 2 fixes the workpiece, it can first move the abutment block 2d upward to separate it from the smooth section 2a2; then rotate the abutment block 2d 90 degrees so that its long side faces the workpiece; next, move the abutment block 2d downward to re-fit it with the smooth section 2a2; then move fixture 2 so that the abutment block 2d abuts the workpiece; finally, make the pressure block 2c fit onto the table to press and fix the workpiece. Correspondingly, after the workpiece is processed, following the above operation, the abutment block 2d is restored to its short side facing the workpiece, so that when fixture 2 returns to storage area 1c4, its own abutment block 2d will not interfere with the abutment blocks 2d on other fixtures 2.

[0039] In some embodiments, based on the above-described embodiment where "the clamp 2 further includes the abutting block 2d", the height of the smooth segment 2a2 is greater than the thickness of the abutting block 2d, and the excess portion is used for the pressure block 2c to be fitted into and to restrict its rotation. This allows the pressure block 2c of the clamp 2 in the storage area 1c4 to remain lateral.
