Description

Technical Field

[0001] The present invention belongs to the technical field of machining tooling, and specifically relates to a clamping tooling for machining holes and surfaces on the outer circle of an anode tank body on a boring machine. Background Art

[0002] There are many holes on the outer circle of the cylindrical anode tank body part, including blind holes and fully-through holes. Due to the large number of holes and the need to mill the copper bar installation surface on the outer circle, it is necessary to use the rotation of the boring machine workbench for indexing drilling. Therefore, drilling and milling are important processes in the manufacture of the anode tank.

[0003] After the cylindrical anode tank is machined on a vertical lathe, the thickness of the tank body plate is relatively thin, only 20 mm. The traditional clamping tooling usually adopts a structural form in which the inner support plate and the pressing plate are arranged on the same plane. Therefore, during machining, the cutting force is easily concentrated on a local area of the workpiece, resulting in uneven stress on the workpiece, and then deformation and displacement occur, seriously affecting the machining accuracy. At the same time, due to the inability to effectively balance the complex external forces generated during the cutting process, chatter is extremely likely to occur, resulting in quality problems such as ripples and dimensional deviations on the machined surface, and it is difficult to meet the high-precision machining requirements.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention. Embodiment 1:

[0021] As Figures 1 to 9 shown, a clamping tooling for machining holes and surfaces on the outer circle of an anode tank body on a boring machine includes a base 1 installed on the boring machine workbench 12.

[0022] A pressing component is installed on the base 1. The pressing component includes four groups of pressing plates 2 that are pressed against the anode tank body. A clamping seat 23 is installed at the bottom of the pressing plate 2. A friction wheel 24 is rotatably installed on the clamping seat 23. When the clamping seat 23 and the anode tank body move relative to each other, the friction wheel 24 rotates. A plug rod 26 that slides downward through the rotation of the friction wheel 24 is movably inserted into the clamping seat 23. The bottom of the plug rod 26 presses against a turning plate 27 installed inside the base 1. A pressing arm 274 is installed on the turning plate 27. The pressing arm 274 is used to press the periphery of the anode tank body to complete the positioning operation. Through this pressing component, automatic clamping can be realized during the clamping process, greatly reducing the operation intensity of workers and improving the clamping efficiency. Moreover, this component adopts the mechanical transmission principle, reducing complex hydraulic or pneumatic devices, lowering the manufacturing cost and maintenance difficulty of the tooling, and at the same time avoiding the risk of clamping failure caused by hydraulic leakage or pneumatic component failure.

[0023] Four groups of positioning columns 3 are also installed on the base 1. A rotating rod 31 is screwed and connected to each group of positioning columns 3 through threads. An inner support plate 32 is installed at the end of the rotating rod 31. The inner support plate 32 presses against the inner side wall of the anode tank body located between adjacent pressing plates 2. The staggered distribution of the pressing plates 2 and the inner support plates 32 is used to apply forces to the anode tank body from multiple directions, increasing stability. This staggered distribution structure can enable the anode tank body to receive uniform forces during the processing, avoiding deformation caused by excessive local stress. For example, when milling the outer circular surface of the anode tank body, the traditional clamping method is likely to cause a large cutting force on one side of the workpiece, resulting in a small offset of the workpiece and affecting the processing accuracy. However, with the staggered distribution structure of the present invention, the inner support plate 32 and the pressing plate 2 can disperse and balance the cutting force from different directions, enabling the workpiece to always remain stable during the processing, thereby significantly improving the processing accuracy and reducing the scrap rate. As Figures 1 to 9 shown, in the specific implementation, a plurality of pairs of mounting grooves 11 are opened on the side wall of the base 1. A locking bolt 111 is screwed and set inside the plurality of mounting grooves 11. A plurality of pairs of slide rails 121 are opened on the boring machine workbench 12. The slide rails 121 correspond to the mounting grooves 11. The locking bolt 111 is screwed and connected to the corresponding slide rail 121. A positioning groove 13 is opened on the base 1. The positioning groove 13 is adapted to the size of the anode tank body. The precise adaptation of the positioning groove 13 to the anode tank body can provide a precise positioning reference for the workpiece at the initial stage of clamping, effectively reducing the subsequent processing errors caused by inaccurate positioning. At the same time, the connection method of the base 1 and the boring machine workbench 12 through the slide rails 121 and the locking bolts 111 makes the installation and disassembly of the tooling more convenient, can quickly adjust the position of the tooling on the workbench, meet different processing requirements, and improve the versatility and processing efficiency of the equipment. Example 2:

[0024] Based on Example 1, the difference in this example is that asFigures 1 to 9 As shown, at the bottom corners of the pressing plate 2, fixing blocks 22 are installed. Inside the fixing blocks 22, inner grooves 221 are formed, and the inner grooves 221 are adapted to the size of the anode tank body. At the bottom of the pressing plate 2, threaded rods 211 are screwed. At the bottom of the threaded rods 211, support rod sleeves 21 are screwed. At the bottom of the support rod sleeves 21, mounting plates 212 are welded. The mounting plates 212 and the bottom of the base 1 are connected by bolts. Through the cooperation of the threaded rods 211 and the support rod sleeves 21, the height of the pressing plate 2 can be conveniently and accurately adjusted to meet the clamping requirements of anode tank bodies of different size specifications. This flexible adjustment method enables a set of tooling to be applicable to the processing of multiple similar workpieces, further improving the versatility of the tooling and reducing the production cost of the enterprise.

[0025] As Figures 1 to 9 shown, in the specific implementation, inside the clamping seat 23, a clamping groove 231 adapted to the size of the anode tank body is formed. Inside the clamping seat 23, an installation cavity 241 is formed. On the side wall of the installation cavity 241, a notch 242 is formed. And the side wall of the friction wheel 24 is placed outside the notch 242. At both ends of the friction wheel 24, positioning shafts 243 are installed. The positioning shafts 243 are screwed to the side wall of the installation cavity 241. This installation method of the friction wheel 24 can ensure its close contact with the surface of the anode tank body and flexible rotation, ensuring that during the clamping process, the relative sliding generated by the downward pressure of the pressing plate 2 can reliably transmit power to trigger subsequent automatic pressing actions, improving the reliability and stability of the entire pressing component.

[0026] As Figures 1 to 9 shown, further, on the rotation center of the friction wheel 24, a rocker arm 25 is installed. At both ends of the rocker arm 25, slide rods 251 are installed. At the top of the insertion rod 26, two pairs of flat plates 261 are installed. The two pairs of flat plates 261 are respectively placed on both sides of the rocker arm 25. And the top of the flat plates 261 is slidably connected to the slide rods 251. This structural design converts the rotational motion of the friction wheel 24 into the linear motion of the insertion rod 26 through simple mechanical transmission, with high transmission efficiency and a compact structure. During the processing, even under the interference of external vibrations and the like, this mechanical transmission structure can ensure the accuracy and reliability of the actions, avoiding clamping failures caused by unstable factors of electronic or hydraulic transmission, and improving the anti-interference ability and working stability of the tooling. Embodiment 3:

[0027] Based on Embodiment 2, the difference in this embodiment is: As Figures 1 to 9As shown, a slide plate 263 is installed on the side wall of the insertion rod 26, and a limit rod 264 is movably provided on the slide plate 263, the bottom of the limit rod 264 is installed on the base 1, and a limit plate 265 for preventing slipping is installed on the top of the limit rod 264, and a limit spring 266 is sleeved on the limit rod 264, one end of the limit spring 266 is clamped on the base 1, and the other end is clamped on the bottom of the slide plate 263. The limit spring 266 facilitates the reset operation later.

[0028] like Figures 1 to 9 As shown, in a specific embodiment, a U-shaped groove 271 is provided on the base 1, and a clamping shaft 272 is rotatably installed on the U-shaped groove 271, and the clamping shaft 272 is connected to the rotation center of the flip plate 27, and a torsion spring 273 is sleeved on the clamping shaft 272, one end of the torsion spring 273 is clamped on the side wall of the U-shaped groove 271, and the other end is clamped on the flip plate 27, and a rolling ball 262 is installed at the bottom of the plug rod 26, and the rolling ball 262 is slidably connected to the flip plate 27, and a pressing roller 275 is installed at the end of the pressing arm 274. The setting of the torsion spring 273 can provide a stable restoring force for the flip plate 27, ensuring that the pressing arm 274 and the pressing roller 275 always press the anode tank body with appropriate pressure. Compared with the traditional plane pressing method, the design of the pressing roller 275 can effectively reduce the friction resistance with the surface of the anode tank body, avoid leaving indentations on the surface of the workpiece, and also improve the reliability of the pressing, ensuring that the workpiece will not be displaced due to insufficient friction during the processing, thereby improving the quality and processing accuracy of the processed surface.

[0029] like Figures 1 to 9 As shown, further, a turntable 311 is installed at one end of the rotating rod 31, a protrusion 312 is installed on the turntable 311, and an anti-slip groove is provided on the surface of the protrusion 312, a positioning block 332 is installed on the side wall of the positioning column 3, a positioning guide rail 33 is installed on the positioning block 332, and the positioning guide rail 33 is in a horizontal state, and a sliding sleeve 331 is slidably provided on the positioning guide rail 33, a connecting box 333 is installed at the end of the sliding sleeve 331, an L-shaped connecting plate 334 is installed on the side wall of the connecting box 333, one end of the L-shaped connecting plate 334 is connected to the bottom of the inner support plate 32, and a reinforcing rib 335 is installed at the corner of the L-shaped connecting plate 334, and the reinforcing rib 335 is triangular, an inner support block 321 is provided on the surface of the inner support plate 32, and the inner side wall of the inner support block 321 is provided with an arc adapted to the anode tank body. The protrusion 312 and anti-slip groove design on the turntable 311 can facilitate workers to rotate the turnbar 31, improving the convenience and comfort of operation. The matching arc between the inner support block 321 and the inner wall of the anode tank body can make the inner support plate 32 more closely contact with the workpiece, increase the contact area, and thus improve the stability and reliability of the inner support. At the same time, the setting of the L-shaped connecting plate 334 and the reinforcing rib 335 enhances the structural strength of the inner support plate 32, making it less likely to deform when subjected to large cutting forces, thereby ensuring the stability and reliability of the tooling during processing.

[0030] The implementation principle of a clamping tooling for machining holes and surfaces on the outer circle of an anode tank body on a boring machine is as follows: First, accurately place the anode tank body into the positioning groove 13 of the base 1. The positioning groove 13 is precisely designed according to the outer contour and dimensions of the anode tank body, and the two have a very high degree of fit, which can provide a stable initial positioning reference for the anode tank body. When placing, ensure that the anode tank body completely falls to the bottom of the positioning groove 13, and its periphery is evenly attached to the side wall of the positioning groove 13 without any deviation or shaking. Subsequently, through the cooperation of the locking bolts 111 and the slide rails 121 between the base 1 and the boring machine workbench 12, the initial positioning and installation of the base 1 on the boring machine workbench 12 are completed.

[0031] By rotating the rotating rod 31, since the rotating rod 31 is screwed and connected to the positioning column 3, when the rotating rod 31 rotates, it will drive the inner support plate 32 to move along the positioning guide rail 33 towards the inner side wall of the anode tank body. The inner support blocks 321 on the inner support plate 32 squeeze against the inner side wall of the anode tank body, providing internal support and positioning for the anode tank body.

[0032] When installing the pressing plate 2, adjust the height of the support rod sleeve 21 by screwing the threaded rod 211, so that the inner groove 221 of the fixed block 22 at the bottom of the pressing plate 2 and the clamping groove 231 of the clamping seat 23 are in close contact with the anode tank body. During the assembly process, the friction wheel 24 is installed in the installation cavity 241 of the clamping seat 23 through the positioning shaft 243, and its side wall extends from the notch 242 and is in direct contact with the surface of the anode tank body. When the pressing plate 2 is pressed down, a relative sliding trend is generated between the anode tank body and the friction wheel 24, thereby driving the friction wheel 24 to start rotating.

[0033] When the friction wheel 24 rotates, it drives the rocker arm 25 to rotate. The slide rods 251 at both ends of the rocker arm 25 slide on the top of the flat plate 261, and the insertion rod 26 slides downward. The rolling ball 262 at the bottom of the insertion rod 26 contacts and presses the turning plate 27, and the turning plate 27 rotates around the clamping shaft 272, and the torsion spring 273 deforms to generate elastic force. At the same time, the pressing arm 274 on the turning plate 27 drives the pressing roller 275 to press the periphery of the anode tank body, further pressing and positioning the anode tank body from the outside.

[0034] During this process, the sliding plate 263 slides along the limiting rod 264, and the limiting spring 266 plays a role in buffering and resetting, ensuring the stability of the movement of the insertion rod 26. The pressing plate 2 and the inner support plate 32 are staggered, applying forces to the anode tank body from multiple directions inside and outside.

[0035] In the traditional clamping method, if the inner support plate 32 and the pressure plate 2 are in the same plane, the force is likely to concentrate in a local area. Under the staggered distribution, the inner support plate 32 and the pressure plate 2 apply forces in different planes. The cutting force can be dispersed and transmitted along different directions of the workpiece through the staggered layout of the inner support and the pressure plate. For example, when milling the outer cylindrical surface of the anode groove body, the lateral force generated by the tool can be shared by the inner support and the pressure plate, avoiding excessive stress on a certain part, preventing workpiece deformation and displacement, ensuring machining accuracy, and solving the problem of tool chatter during the machining of the anode groove holes and surfaces, ensuring the machining quality of the holes and surfaces.

[0036] During the boring process of the boring machine, when the boring tool performs hole machining or plane cutting on the anode groove body, a feeding force along the axial direction of the boring tool, a radial force perpendicular to the machining surface, and a torque generated by the rotation of the tool will be generated. The staggered inner support plate 32 and the pressure plate 2 can form a balanced force system. When the boring tool performs deep hole boring on the anode groove body, the downward feeding force of the boring tool is balanced in the vertical direction by the pressure plate, and the torsional force generated during boring is balanced by the reverse torque provided by the inner support structure located in the adjacent plane; if plane boring is performed, the inner support plate 32 and the pressure plate 2 cooperate to offset the lateral force and vibration generated by cutting, keeping the workpiece in a stable state at all times, ensuring the smooth progress of the machining process, and effectively reducing the machining errors caused by uneven force.
