Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a multi-station tooling and fixture for circular workpieces. Background Technology

[0002] Tooling fixtures are indispensable tools in the manufacturing industry. They are mainly used to fix, position, and clamp workpieces to ensure accuracy and efficiency during the processing. The design and use of tooling fixtures directly affect product quality and production efficiency. They are widely used in many fields such as machining, assembly, welding, and inspection, and are an important means to improve production efficiency and product quality in modern manufacturing.

[0003] A search revealed Chinese patent CN221952815U, which discloses a tooling fixture for circular workpieces. By setting an annular flow channel and a collecting groove, the coolant can be collected and circulated, reducing coolant waste. The bottom surface of the collecting groove is set to be lower than the bottom surface of the discharge groove, which can prevent the coolant in the collecting groove from flowing back into the discharge groove, thereby reducing the amount of coolant flowing into the discharge groove and preventing coolant from flowing out of the installation plate from the discharge groove, thus avoiding coolant waste.

[0004] The aforementioned utility model places the workpiece to be processed on a gripper plate and clamps it in place. Similar to existing technologies, the aforementioned utility model typically adopts a single-station design, which can only fix one workpiece at a time, resulting in low processing efficiency. This makes it difficult to meet the needs of modern manufacturing for large-scale, high-efficiency production. At the same time, the single-station design leads to low space utilization of the processing table, especially when batch processing small workpieces. Based on this, a multi-station tooling fixture for round workpieces is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a multi-station tooling fixture for circular workpieces to solve the problem that a single-station design can only fix one workpiece at a time, resulting in low processing efficiency and difficulty in meeting the needs of modern manufacturing for large-scale, high-efficiency production. At the same time, the single-station design leads to low space utilization of the processing table, especially when batch processing small workpieces.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a multi-station tooling fixture for circular workpieces, including a worktable;

[0007] Positioning mechanisms for clamping and positioning circular parts are provided at both the left and right ends of the upper surface of the worktable, and a recovery mechanism for collecting coolant is provided on the lower side of the worktable.

[0008] The positioning mechanism includes two first protrusions at the left and right ends of the upper surface of the worktable, four clamping plates at the left and right ends of the upper surface of the worktable, a second protrusion at the middle of the upper surface of the worktable, and a limiting block between the opposite sides of the clamping plates on the front and rear sides.

[0009] Positioning blocks are provided on both the left and right sides of the front and rear plates, and four evenly distributed circular protrusions are provided on the upper surface of the worktable.

[0010] Through the above technical solution, the workbench is set up to integrate a first protrusion, a second protrusion, and a positioning block to divide the table surface into multiple independent functional areas. Each area has independent clamping and positioning capabilities, which can fix multiple workpieces at the same time and realize multi-station parallel processing to improve the processing efficiency of workpieces. The optimized spatial layout improves the utilization rate of the workbench's production space.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the side of the first protrusion facing the positioning block is concave in the middle and has two inclined inner walls. The positioning block has the same shape as the first protrusion and is symmetrically distributed on the left and right sides of the vertical central axis of the circular protrusion.

[0013] Through the above technical solution, the inclined plane angle achieves a progressive docking process of first guiding and then positioning, thus realizing the stability of positioning.

[0014] Furthermore, the second protrusion has a central depression on both the left and right sides and beveled side walls. The upper surface of the limiting block has a countersunk hole, and the other end of the countersunk hole extends into the worktable.

[0015] The above technical solution allows the countersunk hole to facilitate the entry of the pin, thereby enabling the horizontal positioning of the limiting block and limiting the position of the two second protrusions.

[0016] Furthermore, a guide groove is provided on the upper surface of the workbench and below the positioning block, and the four circular protrusions are respectively located on the side of the first protrusion or the second protrusion opposite to the positioning block.

[0017] Through the above technical solution, the design of the guide channel enables the sprayed coolant to carry the debris out of the worktable along the guide channel.

[0018] Furthermore, the recycling mechanism includes a collection box located on the lower side of the workbench, a filter plate located inside the collection box, handles fixed to the left and right ends of the upper surface of the filter plate, multiple blocks fixed to the front and rear sides of the workbench, a water guide pipe connected to the lower surface of the blocks, and disassembly parts for easy disassembly and assembly of the filter plate.

[0019] The lower surface of the water guide pipe is connected to an annular ring located on the upper side of the filter plate.

[0020] Through the above technical solution, a recycling mechanism is set on the lower side of the workbench. The coordinated design of the guide channel, baffle and water pipe forms a directional flow channel to ensure that the coolant can flow stably along the preset path. The filter plate can separate the coolant from the debris generated during the processing, so that the coolant can be recycled.

[0021] Furthermore, a connecting block is fixed in the middle between the opposite sides of the front and rear side walls of the inner cavity of the collection box, and its inner bottom wall has a left-right symmetrical inclined structure. Water outlet holes are opened in the middle of the left and right side walls of the inner cavity of the collection box.

[0022] Through the above technical solution, the inclined inner bottom wall facilitates the flow of coolant into the collection tank to the outlet hole along the slope of the inner bottom wall, thereby completing the recovery of coolant.

[0023] Furthermore, the assembly / disassembly components include fixing blocks fixed to the front and rear sides of the left and right side walls of the inner cavity of the collection box and the front and rear sides of the upper surface of the connecting block, slots opened on the upper surface of the fixing blocks, and multiple insert rods fixed to the lower surface of the filter plate.

[0024] The above technical solution allows workers to easily remove the filter plate from the collection box and clean the debris on the filter plate, thus preventing the mesh on the filter plate from becoming clogged.

[0025] Furthermore, the outer diameter of the insertion rod is adapted to the inner diameter of the slot, and multiple insertion rods correspond one-to-one with the slots.

[0026] The above technical solutions ensure smooth assembly and precise positioning during the insertion process.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0028] 1. The worktable integrates a first protrusion, a second protrusion, and a positioning block, dividing the table surface into multiple independent functional areas. Each area has independent clamping and positioning capabilities, which can fix multiple workpieces at the same time, realize multi-station parallel processing, improve workpiece processing efficiency, and improve the production space utilization of the worktable through space optimization layout.

[0029] 2. A recycling mechanism is installed on the lower side of the workbench. It adopts a coordinated design of guide channels, baffles and water pipes to form a directional flow channel, ensuring that the coolant can flow stably along the preset path. The filter plate can separate the coolant from the debris generated during the processing, so that the coolant can be recycled. Attached Figure Description

[0039] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0041] Example: Reference Figure 1 A multi-station tooling fixture for circular workpieces includes a worktable 1; positioning mechanisms 2 for clamping and positioning circular parts are provided at both the left and right ends of the upper surface of the worktable 1, and a recovery mechanism 3 for collecting coolant is provided on the lower side of the worktable 1.

[0042] refer to Figure 2 and Figure 3The positioning mechanism 2 includes two first protrusions 21 located at the left and right ends of the upper surface of the worktable 1, four clamping plates 22 located at the left and right ends of the upper surface of the worktable 1, a second protrusion 23 located in the middle of the upper surface of the worktable 1, and a limiting block 24 located between opposite sides of the clamping plates 22 on the front and rear sides; positioning blocks 25 are provided on the left and right sides of the clamping plates 22 on the front and rear sides, and four evenly distributed circular protrusions 26 are provided on the upper surface of the worktable 1.

[0043] The first protrusion 21 has a central depression on the side facing the positioning block 25 and two inclined surfaces on its inner sidewalls. The positioning block 25 has the same shape as the first protrusion 21 and is symmetrically distributed on the left and right sides of the vertical central axis of the circular boss 26.

[0044] The first protrusion 21 has the opposite shape to the positioning block 25, so that the two sides of the workpiece can be clamped when the positioning block 25 moves, thereby achieving the positioning of the workpiece in a horizontal position.

[0045] In this embodiment, the left and right sides of the second protrusion 23 are both recessed in the middle and the side walls are inclined. The upper surface of the limiting block 24 is provided with a countersunk hole, and the other end of the countersunk hole extends into the worktable 1. The upper surface of the worktable 1 and the lower side of the positioning block 25 is provided with a guide groove 27. The four circular protrusions 26 are respectively located on the side of the first protrusion 21 or the second protrusion 23 opposite to the positioning block 25.

[0046] In use, the workpiece is placed on the circular boss 26, and then the limiting block 24 is placed between the two clamping plates 22 on opposite sides. The pin is inserted into the countersunk hole on the upper surface of the limiting block 24, thereby fixing the position of the limiting block 24. When the limiting block 24 is placed between the two clamping plates 22, it can press against the two positioning blocks 25, thereby allowing the two positioning blocks 25 to move towards the side closer to the first protrusion 21 and the second protrusion 23, thereby clamping the two sides of the workpiece and completing the positioning of the workpiece. Then, the drilling process can be performed.

[0047] refer to Figure 5 and Figure 6 The recycling mechanism 3 includes a collection box 31 located on the lower side of the workbench 1, a filter plate 32 located in the inner cavity of the collection box 31, handles 33 fixed to the left and right ends of the upper surface of the filter plate 32, multiple blocks 34 fixed to the front and rear sides of the workbench 1, a water guide pipe 35 connected to the lower surface of the block 34, and disassembly parts for easy disassembly and assembly of the filter plate 32; the lower surface of the water guide pipe 35 is connected to an annular ring located on the upper side of the filter plate 32.

[0048] The collection box 31 has a connecting block fixed in the middle between the opposite sides of the front and rear side walls of the inner cavity, and its inner bottom wall has a symmetrical inclined structure. Water outlet holes are opened in the middle of the left and right side walls of the inner cavity of the collection box 31. The inner bottom wall of the collection box 31 is triangular in shape so that the coolant at the bottom of the collection box 31 can flow towards the water outlet hole with the guidance of the inner bottom wall of the collection box 31, so that it can flow out through the water outlet hole for easy recycling.

[0049] It should be noted that the water guide pipe 35 is a flexible hose, which can be perpendicular to the collection box 31 by the gravity of the ring, so that the water guide pipe 35 can be moved upward when the filter plate 32 is disassembled and assembled, thus avoiding obstruction.

[0050] During use, the sprayed coolant flows along the surface of the workbench 1 during processing, and converges through the gap between the circular boss 26 and the workbench 1 and the guide groove 27. The baffle 34 can form a flow barrier to ensure that the coolant flows into the water guide pipe 35 in a directional manner. The water guide pipe 35 delivers the coolant to the collection tank 31, where it needs to be filtered by the filter plate 32. When the coolant flows through the filter plate 32, impurities such as metal shavings are intercepted by the filter screen of the filter plate 32. The filtered clean liquid leaks into the bottom of the collection tank 31. Under the action of gravity, the liquid flows naturally to the water outlets on both sides to avoid residue. The water outlets are connected to the external recycling pipe to deliver the filtered coolant to the circulation system for reuse.

[0051] In this embodiment, the assembly and disassembly components include fixing blocks 36 fixed to the front and rear sides of the left and right side walls of the inner cavity of the collection box 31 and the front and rear sides of the upper surface of the connecting block, slots 37 opened on the upper surface of the fixing blocks 36, and multiple insert rods 38 fixed to the lower surface of the filter plate 32.

[0052] The outer diameter of the insertion rod 38 is matched with the inner diameter of the slot 37. Multiple insertion rods 38 correspond one-to-one with slots 37. The arrangement of insertion rods 38 and slots 37 facilitates the disassembly and assembly of the filter plate 32, thereby facilitating the regular cleaning of the debris filtered out on the filter plate 32 and preventing the low filtration efficiency of the coolant due to the blockage of the filter plate 32 mesh.

[0053] During use, the filter plate 32 is fixed to the collection box 31 by the insertion rod 38 and the slot 37 on the fixing block 36, so that the filter plate 32 can be quickly removed for cleaning. The operator can disassemble the filter plate 32 by holding the handle 33 and lifting it upwards, which is convenient for regular removal of deposited debris and maintaining filtration efficiency.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
