If the trimming and hole-making process is completed on one side, the operator also needs to raise the blank to make holes. If the trimming and hole-making process is completed on both sides, the operator needs to align both sides and confirm the processing origin. This traditional processing method is not only cumbersome in the operation process, but also inefficient and unable to meet the requirements of batch and efficient processing. At the same time, whether it is to ensure that the position of the pressure plate does not interfere with the tool during the processing process, or to raise and level the parts, or to repeatedly align and center, there are certain processing risks, which may cause collisions and positioning deviations, resulting in processing equipment failure or part scrapping.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 2The present invention provides a technical solution: a finishing and hole-making tooling for fixing workpieces of different sizes, comprising: a threaded hole tray 1 and a T-slot tray 2, the threaded hole tray 1 is evenly distributed with threaded holes, a plurality of vertical positioning blocks 3 and a plurality of horizontal positioning blocks 4 are installed on the top of the threaded hole tray 1 and the T-slot tray 2, a part of the vertical positioning blocks 3 and a part of the horizontal positioning blocks 4 are horizontally penetrated with a threaded fastening screw 5, and the inner end of the fastening screw 5 extends toward the center of the threaded hole tray 1 or the center of the T-slot tray 2;

[0029] The vertical positioning block 3 and the horizontal positioning block 4 on the top of the threaded hole tray 1 are vertically penetrated by threaded positioning screws 6, and the vertical positioning block 3 and the horizontal positioning block 4 on the top of the T-slot tray 2 are vertically penetrated by top rods 7, and the vertical positioning block 3 and the horizontal positioning block 4 can be removed from the threaded hole tray 1 and the T-slot tray 2.

[0030] In specific implementation, the trimming and hole-making tooling can be fixed to workpieces of different sizes. When the parts need to be trimmed and hole-made, the parts can be placed on the corresponding threaded hole tray 1 or T-slot tray 2. Since all components of the threaded hole tray 1 or T-slot tray 2 are made of 45 steel, supplemented by 30-45 heat treatment and surface blackening treatment, they have higher hardness, strength and good wear resistance, as well as strong corrosion resistance, low cost and strong adaptability;

[0031] When the part needs to be clamped on the threaded hole tray 1, the vertical positioning block 3 and the horizontal positioning block 4 can be installed around the part according to the size of the part, and then the positioning screw 6 can be inserted into the vertical positioning block 3 and the horizontal positioning block 4, and the positioning screw 6 can be rotated. Since the positioning screw 6 and the vertical positioning block 3, the horizontal positioning block 4 and the threaded hole tray 1 are all threadedly connected, the first positioning screw 6 can be rotated to pass through the corresponding vertical positioning block 3 and the horizontal positioning block 4 and move into the threaded hole of the threaded hole tray 1. The vertical positioning block 3 and the horizontal positioning block 4 can be fixed by the two sets of positioning screws 6. At the same time, the fastening screw 5 on the vertical positioning block 3 and the horizontal positioning block 4 of the rotating part, similarly, since the fastening screw 5 and the vertical positioning block 3 and the horizontal positioning block 4 are threadedly connected, the fastening screw 5 can be rotated to make the fastening screw 5 move in the direction of the part. With the cooperation of the fastening screw 5, the vertical positioning block 3 and the horizontal positioning block 4, parts of different sizes can be clamped on the threaded hole tray 1, thereby facilitating the fixing of parts of different sizes.

[0032] When the part is clamped on the T-slot tray 2, the corresponding vertical positioning blocks 3 and horizontal positioning blocks 4 can also be placed around the part, and the clamping rod 13 on one side of the fixing block 12 is pulled to one side, so that the clamping rod 13 drives the protrusion 16 to move toward the fixing block 12, and the clamping rod 13 will make the movable spring 15 in a stretched state through the telescopic block 14, and then push the push rod 7 to the bottom of the vertical positioning block 3 and the horizontal positioning block 4, so that the connecting block 8 at the bottom of the push rod 7 drives the clamping block 9 and the T-slot tray 2 for docking, and then release the clamping rod 13, the clamping rod 13 will be driven to reset through the movable spring 15, and the protrusion 16 at one end of the clamping rod 13 will be docked with the groove of the T-slot tray 2. Through the cooperation of the protrusion 16 and the clamping rod 13, the clamping block 9 can always be docked with the rack 17 at the bottom of the T-slot tray 2, so that the vertical positioning block 3 and the horizontal positioning block 4 can be fixed. Through the vertical positioning block 3 and the horizontal positioning block 4, parts of different sizes can be limited on the T-slot tray 2.

[0033] See also Figure 1-Figure 7 It can be seen that when in use, the corresponding parts can be placed on the threaded hole tray 1 or the T-slot tray 2. Through the cooperation of the vertical positioning block 3 and the horizontal positioning block 4, the number of vertical positioning blocks 3 and horizontal positioning blocks 4 used can be different according to the size of the part blank. Therefore, the tooling can be suitable for blanks of different sizes and flexibly meet their surface finishing and hole making needs. At the same time, some of the horizontal positioning blocks 4 have vertical sliding threads on the surface that engages with the part, and the horizontal positioning block 4 with the fastening screw 5 and the part have a smooth plane. At this time, the horizontal position of the part is fixed but it can still slide in the vertical direction. Then, the vertical direction of the part is fixed by the oblique 45° cross teeth on the engaging surface of some vertical positioning blocks 3 and the part and the engaging surface of the fastening screw 5 and the part is annular teeth. At this time, the part is locked and cannot move in any direction when subjected to general cutting force.

[0034] A connecting block 8 is installed at the bottom of the top rod 7, and a clamping block 9 is installed at the bottom of the connecting block 8. The top of the connecting block 8 is connected to a guide rod 10 that passes through the vertical positioning block 3 and the horizontal positioning block 4 through a slide groove. A collar 11 is sleeved on the outer side of the guide rod 10, and a fixed block 12 is installed on one side of the collar 11. A clamping rod 13 is penetrated and connected to the top of the fixed block 12, and a telescopic block 14 is installed on one side of the clamping rod 13. A movable spring 15 is connected between the groove of the telescopic block 14 and the fixed block 12, and a protrusion 16 is connected between the clamping rod 13 and the groove of the T-slot tray 2. A rack 17 is installed in the groove at the bottom of the T-slot tray 2, and the T-slot tray 2 and the rack 17 are an integrated structure. The top rod 7 and the connecting block 8 are an integrated structure. The clamping rod 13 passes through and is inserted into the vertical positioning block 3, and the horizontal positioning block 4 is inserted into the slot at the top of the T-slot tray 2, and the clamping rod 13 and the protrusion 16 are an integrated structure.

[0035] In specific implementation, the trimming and hole-making tooling can be used to fix workpieces of different sizes. When it is necessary to fix parts of different shapes, it is only necessary to adjust the vertical positioning block 3 and the horizontal positioning block 4 at the corresponding position, so that the connecting block 8 and the clamping block 9 are then driven to rotate by the top rod 7, so that the clamping block 9 is docked with the rack 17 in the T-slot tray 2, and the above steps are repeated, so that the clamping rod 13 limits the vertical positioning block 3 and the horizontal positioning block 4 on the T-slot tray 2 through the protrusion 16, so that parts of different shapes can be fixed;

[0036] At the same time, when using this tooling, the NC program uses the machine tool coordinate system as the processing coordinate system, and the operator is no longer required to manually align the parts and determine the processing coordinate system. At the same time, since there are no redundant objects such as pressure plates on the surface of the parts at this time, the trimming work and the hole making work can be carried out at the same time. Therefore, the tooling design not only improves the efficiency of the trimming and hole making work, but also reduces the processing risk.

[0037] See also Figure 1-Figure 7 It can be seen that when in use, since the fastening screw 5 of the vertical positioning block 3 has a sharp ejector pin and the corresponding vertical positioning block 3 is an annular engaging tooth structure, it can be clamped with the clamped parts in a multi-point contact manner, and at the same time, the clamping structure can clamp the parts obliquely. It is only necessary to adjust the position and direction of the vertical positioning block 3 and the horizontal positioning block 4 to ensure that the engaging teeth of the ejector block and the clamping teeth of the clamping screw are engaged at the inflection point of the blank shape, so that parts of different shapes can be processed.

[0038] To sum up, when the trimming and hole-making tooling that can fix workpieces of different sizes is in use, the parts to be processed can be placed on the corresponding threaded hole tray 1 or T-slot tray 2, and then a corresponding number of vertical positioning blocks 3 and horizontal positioning blocks 4 are placed around the parts, and the positions of the vertical positioning blocks 3 and the horizontal positioning blocks 4 are fixed. At this time, the parts can be trimmed and holes can be made, thereby ensuring the stability of the entire part. This is the use feature of the trimming and hole-making tooling that can fix workpieces of different sizes.
