Description

Technical Field

[0001] This utility model relates to the field of valve body processing technology, specifically a multi-axis clamping device for valve body processing. Background Technology

[0002] In the field of mechanical manufacturing, valves, as key components in fluid control systems, have their sealing performance, pressure resistance, and service life directly affected by the machining quality of their bodies. With the rapid development of industrial automation and intelligent manufacturing technologies, higher demands are being placed on the machining accuracy and production efficiency of valve bodies. During the valve body machining process, the clamping device is a core component ensuring machining accuracy and stability; its performance directly affects product quality and production efficiency.

[0003] In the machining process of valve bodies, to ensure machining accuracy and quality, the valve body must be firmly fixed to the base. However, existing conventional clamping devices mostly use a single method of fixing at both ends. Since the valve body often bears multi-directional cutting forces during machining, a single clamping at both ends is insufficient to balance these complex external forces, causing varying degrees of shaking and displacement of the valve body during machining. Especially during machining processes with extremely high stability requirements, such as milling and boring, even slight shaking can cause relative positional shifts between the tool and the workpiece, leading to problems such as deviations in hole diameter and excessive surface roughness. This not only reduces machining efficiency but also seriously affects the overall machining accuracy and product qualification rate of the valve body, significantly increasing the company's production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-axis clamping device for processing valve bodies, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a multi-axis clamping device for valve body processing, including a base, a transverse clamping mechanism at the top of the base, and a longitudinal clamping mechanism at the bottom of the transverse clamping mechanism.

[0006] The lateral clamping mechanism includes support rods fixedly connected to the four corners of the top of the base. Each support rod has a cam rotatably connected to one side. Two of the cams have a first gear fixedly connected to one side, and two of the first gears have a second gear meshing with one side. Two opposing cams are rotatably connected to a first connecting rod, and one end of each first connecting rod passes through one side of the cam and is fixedly connected to one side of the second gear. A second connecting rod is fixedly connected to the middle of the outer wall of each of the two first connecting rods. The other end of each of the two second connecting rods is fixedly connected to a partition. A retaining ring is fixedly connected to the bottom of one side of each of the two partitions.

[0007] In one example, racks are meshed on one side of both first gears, and base plates are fixedly connected to the bottom of both racks, with two strip-shaped holes on the top of the base plates.

[0008] In one example, the longitudinal clamping mechanism includes two baffles fixedly connected to the top sides of the base, with a bidirectional lead screw rotatably connected between each pair of opposing baffles. Both ends of the outer walls of the two bidirectional lead screws are threaded with movable blocks, and a support plate is fixedly connected to the top of each movable block.

[0009] In one example, each of the support plates is fixedly connected to a mounting base on both sides, a clamp is rotatably connected between every two mounting bases, and a torsion spring is embedded on one side of each mounting base.

[0010] In one example, one side of each of the two baffles is rotatably connected to a synchronous pulley, the outer wall of the two synchronous pulleys is fitted with a synchronous belt, one side of one of the baffles is fixedly connected to a servo motor, and one of the synchronous pulleys is fixedly connected to the output end of the servo motor.

[0011] In one example, both ends of the top of the base are fixedly connected to limit rods, and the limit rods are interlocked with the four corners of the base plate. Each limit rod is fitted with a spring on its outer wall.

[0012] In one example, a smart control panel is provided on one side of the base, and a servo motor switch is provided on the surface of the smart control panel. The servo motor is electrically connected to an external power supply through the servo motor switch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A support rod is installed on the top of the base, and cams and first gears are installed on one side of two of the support rods. The rotation of the first gear can drive the second gear located on one side of the first gear to rotate. A first connecting rod is provided on one side of each cam, and one end of the first connecting rod is rotatably connected to one side of the cam, and the other end is connected to the second gear. A second connecting rod is provided on one side of the two first connecting rods. The second connecting rod is connected to a fixing ring through a partition. When the two ends of the valve are placed on the fixing ring, the pressure of the valve's own weight will drive the cams on both sides to swing downward, which will drive the partitions on both sides to gather inward, thus fixing the two sides of the valve in the first step. Under the action of the valve's own weight, no driving source is needed. The partitions on both sides can perform the initial clamping treatment. A rack is provided on the two first gears, and a base plate is provided at the bottom of the rack. When the cams rotate, the second gear will drive the first gear to rotate, which will drive the rack to move upward, and the bottom plate will lift up to prevent the valve from falling off.

[0015] 2. In use, when the top transverse clamping mechanism clamps the valve laterally, a baffle is provided on the top of the base, and a double-acting screw is provided between the two baffles. The outer wall of the double-acting screw is provided with a movable block. A fixed seat and a clamping plate are provided on the top of the movable block through a support plate. The clamping plate can move under the action of a torsion spring. When the movable blocks on both sides converge inward, the clamping plate will open, thereby fixing the valve longitudinally. In cooperation with the top transverse clamping mechanism, the valve can be clamped in multiple axes, which improves the stability during the valve processing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a multi-axis clamping device for processing valve bodies, including a base 1, a transverse clamping mechanism 2 at the top of the base 1, and a longitudinal clamping mechanism 3 at the bottom of the transverse clamping mechanism 2.

[0024] The transverse clamping mechanism 2 includes support rods 201 fixedly connected to the four corners of the top of the base 1. Each support rod 201 is rotatably connected to a cam 202 on one side. Two cams 202 are fixedly connected to a first gear 203 on one side. Two first gears 204 are meshed with one side of each first gear 203. Two opposing cams 202 are rotatably connected to a first connecting rod 205. One end of each first connecting rod 205 passes through one side of the cam 202 and is fixedly connected to one side of the second gear 204. A second connecting rod 206 is fixedly connected to the middle of the outer wall of each first connecting rod 205. A partition 207 is fixedly connected to the other end of each second connecting rod 206. A fixing ring 208 is fixedly connected to the bottom of one side of each partition 207.

[0026] In use, the support rods 201 located on the top of the base 1, and the cams 202 and first gears 203 located on one side of two of the support rods 201, rotate the first gear 203, which in turn drives the second gear 204 located on one side of the first gear 203 to rotate. A first connecting rod 205 is located on one side of each cam 202, with one end of the first connecting rod 205 rotatably connected to one side of the cam 202 and the other end connected to the second gear 204. A second connecting rod 206 is located on one side of each of the two first connecting rods 205, and the second connecting rod 206 is connected to a fixing ring 208 via a partition 207. When both ends of the valve are placed on the fixing ring 208... When the valve is above 8, under the pressure of its own weight, the cams 202 on both sides will swing downward, which will cause the partitions 207 on both sides to converge inward, thus fixing the valve on both sides in the first step. Under the action of the valve's own weight, no driving source is needed. The partitions 207 on both sides can perform the initial clamping treatment. There are racks 209 on the two first gears 203. The bottom of the racks 209 is provided with a base plate 210. When the cams 202 rotate, the second gear 204 will drive the first gear 203 to rotate, which will drive the racks 209 to move upward. Then the bottom plate 210 will lift up to prevent the valve from falling off.

[0027] Furthermore, the longitudinal clamping mechanism 3 includes two baffles 301 fixedly connected to the top two sides of the base 1. A bidirectional lead screw 302 is rotatably connected between each pair of opposing baffles 301. Movable blocks 303 are threaded to both ends of the outer walls of the two bidirectional lead screws 302. A support plate 304 is fixedly connected to the top of each movable block 303.

[0028] Each support plate 304 has a fixed seat 305 fixedly connected to both sides, and a clamping plate 306 is rotatably connected between every two fixed seats 305. A torsion spring 307 is embedded on one side of each fixed seat 305.

[0029] In use, when the top transverse clamping mechanism 2 clamps the valve laterally, a baffle 301 is provided on the top of the base 1, and a two-way screw 302 is provided between the two baffles 301. A movable block 303 is provided on the outer wall of the two-way screw 302. A fixed seat 305 and a clamping plate 306 are provided on the top of the movable block 303 through a support plate 304. The clamping plate 306 can move under the action of the torsion spring 307. When the movable blocks 303 on both sides converge inward, the clamping plate 306 will open, thereby fixing the valve longitudinally. With the cooperation of the top transverse clamping mechanism 2, the valve can be clamped in multiple axes, which improves the stability during the valve processing.

[0030] Furthermore, a synchronous pulley 308 is rotatably connected to one side of each of the two baffles 301, and a synchronous belt 309 is sleeved on the outer wall of the two synchronous pulleys 308. A servo motor 310 is fixedly connected to one side of one of the baffles 301, and one of the synchronous pulleys 308 is fixedly connected to the output end of the servo motor 310.

[0031] A synchronous pulley 308 and a synchronous belt 309 are provided on one side of the baffle 301. The two synchronous pulleys 308 are driven by the synchronous belt 309, and the clamps 306 on both sides can be driven synchronously by the servo motor 310.

[0032] Furthermore, both ends of the top of the base 1 are fixedly connected to limit rods 311, and the limit rods 311 are interlocked with the four corners of the base plate 210. Each limit rod 311 is fitted with a spring 312 on its outer wall.

[0033] A limiting rod 311 and a spring 312 are provided on the top of the base 1. The limiting rod 311 is inserted into the top of the base plate 210, which can prevent the base plate 210 from deviating during use.
