Description

Technical Field

[0001] This utility model relates to the field of metal workpiece processing, specifically a metal workpiece processing fixture. Background Technology

[0002] Metal workpiece processing fixtures (full name "process equipment") refer to a general term for various auxiliary tools, devices or equipment designed to achieve functions such as positioning, clamping, guiding and supporting workpieces in the metal processing process. Bench vises are a type of metal workpiece processing fixtures. Their main function is to clamp workpieces and prevent them from moving during processing. They are suitable for clamping small workpieces.

[0003] Existing metal workpiece processing fixtures (such as bench vises) are equipped with structures such as lead screws, movable seats, and fixed seats. Clamping plates are bolted to one side of the fixed seat and the other side of the movable seat. The movable seat is connected to a threaded seat by bolts. When a metal workpiece is placed between the movable seat and the fixed seat, the movable seat is moved by rotating the lead screw so that it can clamp and limit the metal workpiece in conjunction with the fixed seat, facilitating subsequent processing by the processing equipment. However, the processing generates debris, some of which falls into the Phillips head or slotted head of the bolt. Over time, a large amount of debris accumulates in the Phillips head or slotted head of the bolt, making it difficult to insert a screwdriver into the Phillips head or slotted head and turn the thread, thus reducing the bolt unscrewing efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a metal workpiece processing fixture to solve the technical problem that the debris generated during the processing will fall into the cross groove or slot of the bolt head, thus affecting the subsequent disassembly of the bolt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal workpiece processing fixture, comprising a base and a movable seat. A fixed seat is installed on one side of the top of the base. Two second screw holes are opened on one side of the movable seat and one side of the fixed seat. Clamping plates are also placed on one side of the movable seat and one side of the fixed seat. A second bolt extending into the second screw hole is threadedly connected to one side of the clamping plate. Two second storage slots are opened on one side of each clamping plate, and a second sealing plug is inserted inside the second storage slot. A first storage slot is opened on the top of the movable seat, and a first sealing plug is inserted inside the first storage slot. A top plate is fixed on the top of the first sealing plug. A first bolt is threadedly connected inside the movable seat. A groove is opened on the bottom of the base, and a lead screw is connected to one side of the groove via a bearing. A threaded seat is fitted on the outer wall of the lead screw, and a fixing plate is installed on both sides of the threaded seat via fastening bolts. A chip baffle is fixed on one side of the fixing plate.

[0006] By adopting the above technical solution, when the threaded seat moves, it will drive the two chip baffles to move simultaneously. The two chip baffles can continuously block the lead screw, thereby preventing chips from falling onto the lead screw and improving the protection effect on the lead screw.

[0007] Furthermore, through slots are provided on both sides of the base, and the chip baffle passes through the through slots, with the outer wall of the chip baffle fitting against the inner wall of the through slots.

[0008] By adopting the above technical solution, the through slot design facilitates the smooth movement of the chip baffle, preventing the base from obstructing the movement of the chip baffle.

[0009] Furthermore, a limiting groove is provided on the top of the base, and a limiting block is provided inside the limiting groove, with a movable seat installed on the top of the limiting block.

[0010] By adopting the above technical solution, the movement of the threaded seat can drive the limiting block to slide inside the limiting groove, and then drive the movable seat to move so as to adjust the position of the movable seat.

[0011] Furthermore, one end of the lead screw extends through to the outside of the base and is fitted with a rotating head.

[0012] By adopting the above technical solution, it is convenient for workers to rotate the lead screw by turning the head, and the rotation of the lead screw can drive the threaded seat to move.

[0013] Furthermore, the top of the limiting block is provided with a first screw hole, and the bottom end of the first bolt extends into the interior of the first screw hole.

[0014] By adopting the above technical solution, the first screw hole is designed to facilitate the screwing in of the first bolt.

[0015] Furthermore, the bolt head of the first bolt is located inside the first receiving groove, and the bolt head of the second bolt is located inside the second receiving groove.

[0016] By adopting the above technical solution, the bolt head of the first bolt can be stored inside the first storage groove, and the bolt head of the second bolt can be stored inside the second storage groove.

[0017] Furthermore, two through holes are provided between one of the clamping plates and the fixed seat, and between the other clamping plate and the movable seat, and the through holes correspond one-to-one with the second storage slot.

[0018] By adopting the above technical solution, when the second sealing plug needs to be removed, the staff can use an external thin rod to insert the thin rod into the through hole and push the thin rod so that the thin rod pushes the second sealing plug, making it easy for the second sealing plug to protrude from the second storage groove, and then the second sealing plug can be removed.

[0019] Furthermore, the top of the chip baffle is smooth, and both the outer surface and the back of the chip baffle are sloped.

[0020] By adopting the above technical solution, when the cutting fluid flows into the chip baffle, the outer surface and back of the chip baffle are both set with slopes to facilitate the downward flow of the cutting fluid from the chip baffle.

[0021] Furthermore, the width of the chip baffle is greater than the diameter of the lead screw, and the chip baffle is located directly above the lead screw.

[0022] By adopting the above technical solution, the chip baffle can shield and protect the lead screw, preventing the chips generated during the processing from falling directly onto the lead screw.

[0023] Furthermore, both the first and second sealing plugs are made of silicone rubber.

[0024] By adopting the above technical solution, the first and second sealing plugs are made elastic, which facilitates the deformation and compression of the first and second sealing plugs.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model is provided with a first storage groove, a first sealing plug, a second storage groove, and a second sealing plug. Both the first and second sealing plugs are made of silicone rubber, which makes them elastic. This allows the first sealing plug to be easily inserted into the first storage groove to protect the head of the first bolt. When the second sealing plug is inserted into the second storage groove, it can protect the head of the second bolt, preventing debris from falling into the cross-shaped or slotted groove at the end of the bolt head. This avoids clogging the cross-shaped or slotted groove of the bolt head, making it easier to insert a screwdriver into the cross-shaped or slotted groove and turn the bolt, thereby improving the unscrewing efficiency of the first and second bolts.

[0027] 2. This utility model is equipped with chip baffles. When the threaded seat moves, it will drive the two chip baffles to move simultaneously. The two chip baffles can continuously block the lead screw, thereby preventing chips from falling onto the lead screw and avoiding subsequent jamming of the threaded seat on the lead screw, thus improving the protection effect of the lead screw. The through groove is provided to facilitate the smooth movement of the chip baffles and avoid the base from obstructing the movement of the chip baffles. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A tooling fixture for machining metal workpieces, such as Figures 1-7 As shown, the device includes a base 1 and a movable seat 3. A fixed seat 2 is installed on one side of the top of the base 1. Two second screw holes 13 are opened on one side of the movable seat 3 and one side of the fixed seat 2. A clamping plate 14 is also placed on one side of the movable seat 3 and one side of the fixed seat 2. A second bolt 21 extending into the second screw hole 13 is threadedly connected to one side of the clamping plate 14. Two second storage slots 15 are opened on one side of the two clamping plates 14. A second sealing plug 16 is installed inside the second storage slot 15. A first storage slot 11 is opened on the top of the movable seat 3. A first sealing plug 12 is installed inside the first storage slot 11.

[0040] See Figures 1-5The top of the first sealing plug 12 is fixed with a top plate 22. The movable seat 3 is internally threaded with a first bolt 10. The bottom of the base 1 has a groove 6, and a lead screw 8 is connected to one side of the groove 6 through a bearing. The outer wall of the lead screw 8 is fitted with a threaded seat 7, and a fixing plate 17 is installed on both sides of the threaded seat 7 through fastening bolts. A chip baffle 18 is fixed on one side of the fixing plate 17. When the threaded seat 7 moves, it will drive the two chip baffles 18 to move simultaneously. The two chip baffles 18 can continuously block the lead screw 8, thereby preventing debris from falling onto the lead screw 8, so as to improve the protection effect of the lead screw 8. One end of the lead screw 8 extends to the outside of the base 1 and is equipped with a rotating head 20, which allows the operator to rotate the lead screw 8 through the rotating head 20. When the lead screw 8 rotates, it can drive the threaded seat 7 to move.

[0041] See Figures 1-7 The top of the limiting block 5 has a first screw hole 9, and the bottom end of the first bolt 10 extends into the first screw hole 9. The first screw hole 9 facilitates the screwing in of the first bolt 10. The bolt head of the first bolt 10 is located inside the first receiving groove 11, and the bolt head of the second bolt 21 is located inside the second receiving groove 15. The bolt head of the first bolt 10 can be stored inside the first receiving groove 11, and the bolt head of the second bolt 21 can be stored inside the second receiving groove 15. The first sealing plug 12 is adapted to the first receiving groove 11. The second sealing plug 16 is adapted to the second storage slot 15. Two through holes 23 are provided between one clamping plate 14 and the fixed seat 2 and between the other clamping plate 14 and the movable seat 3. The through holes 23 correspond one-to-one with the second storage slot 15. When the second sealing plug 16 needs to be removed, the staff can use an external thin rod to insert the thin rod into the through hole 23 and push the thin rod so that the thin rod pushes the second sealing plug 16, thus making the second sealing plug 16 protrude from the second storage slot 15, thereby making it easier to remove the second sealing plug 16.

[0042] Specifically, the top of the chip baffle 18 is smooth, and both the outer surface and back of the chip baffle 18 are sloped. When the cutting fluid flows onto the chip baffle 18, the sloped outer surface and back of the chip baffle 18 facilitate the downward flow of the cutting fluid from the chip baffle 18. The width of the chip baffle 18 is greater than the diameter of the lead screw 8. The chip baffle 18 is located directly above the lead screw 8, and the chip baffle 18 can shield and protect the lead screw 8, preventing the chips generated during the machining process from falling directly onto the lead screw 8. The first sealing plug 12 and the second sealing plug 16 are both made of silicone rubber, which makes the first sealing plug 12 and the second sealing plug 16 elastic, thereby facilitating the deformation and compression of the first sealing plug 12 and the second sealing plug 16. The diameter of the top plate 22 is greater than the diameter of the first receiving groove 11.

[0043] Example 2:

[0044] Based on the above embodiment 1, the following structure will be set to facilitate the smooth movement of the chip baffle 18.

[0045] See Figure 1 , Figure 3 and Figure 4 Both sides of the base 1 are provided with through slots 19, and the chip baffle 18 passes through the through slots 19. The outer wall of the chip baffle 18 fits against the inner wall of the through slot 19. The through slot 19 is designed to facilitate the smooth movement of the chip baffle 18 and prevent the base 1 from obstructing the movement of the chip baffle 18.

[0046] Example 3:

[0047] Based on the above embodiment 1, in order to improve the stability of the movable seat 3 when it moves, it is necessary to guide the movable seat 3, so the following structure will be set.

[0048] Specifically, the top of the base 1 is provided with a limiting groove 4, and a limiting block 5 is provided inside the limiting groove 4. A movable seat 3 is installed on the top of the limiting block 5. The limiting groove 4 is connected to the groove 6. The movable seat 3 is slidably connected to the limiting groove 4 through the limiting block 5. The movement of the threaded seat 7 can drive the limiting block 5 to slide inside the limiting groove 4, and then drive the movable seat 3 to move, so as to adjust the position of the movable seat 3. The setting of the limiting block 5 and the limiting groove 4 can guide the movable seat 3, thereby improving the stability of the movable seat 3 when it moves.

[0049] The working principle of this utility model is as follows: First, before use, the operator can install the tooling on the processing equipment. After installation, the metal part to be processed is placed between the movable seat 3 and the fixed seat 2. Then, the screw 8 is rotated by the rotating head 20. The rotation of the screw 8 drives the threaded seat 7 to move and drives the movable seat 3 to move, so that the movable seat 3 and the fixed seat 2 can clamp and limit the metal part. After the metal part is clamped, the rotating head 20 is no longer rotated.

[0050] When the threaded seat 7 moves, it will drive the two chip baffles 18 to move simultaneously. The two chip baffles 18 can block the lead screw 8, thereby preventing chips from falling onto the lead screw 8 and thus avoiding the threaded seat 7 from getting stuck on the lead screw 8. It is also provided with a through groove 19 to facilitate the smooth movement of the chip baffles 18 and prevent the base 1 from obstructing the movement of the chip baffles 18.

[0051] Both the first sealing plug 12 and the second sealing plug 16 are made of silicone rubber, making them elastic. This allows the first sealing plug 12 to be easily inserted into the first receiving groove 11 to protect the bolt head of the first bolt 10. When the second sealing plug 16 is inserted into the second receiving groove 15, it can protect the bolt head of the second bolt 21, preventing debris from falling into the Phillips head or slot at the end of the bolt head and thus avoiding blockage. This makes it easier to insert a screwdriver into the Phillips head or slot and turn the bolt. At the same time, the metal part will squeeze the second sealing plug 16 during clamping, causing the second sealing plug 16 to deform, so that the second sealing plug 16 will not affect the clamping of the metal part.

[0052] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
