Description
Technical Field
[0001] This utility model belongs to the technical field of hardware product processing equipment, and specifically relates to an automatic grooving fixture for hardware products. Background Technology
[0002] In the hardware processing industry, grooving is a common production process. Currently, in actual production, when multiple workpieces (such as five workpieces) need to be continuously grooved, manual clamping is still the most common method. This traditional manual clamping method has many drawbacks:
[0003] First, when using automatic grooving equipment for cyclic processing, the operator needs to manually adjust and fix the workpiece position repeatedly, which forces the processing flow to be interrupted, seriously affecting production efficiency and processing continuity.
[0004] Secondly, after each grooving process is completed, the operator must manually release the clamping device and remove the workpiece. This frequent manual intervention not only increases the labor intensity, but also significantly extends the average processing time of a single product.
[0005] Furthermore, repetitive manual operations near high-speed rotating machinery pose significant safety hazards. Operators' fingers or tools are highly susceptible to accidental contact with moving parts, leading to mechanical injuries. Especially during mass production, the cumulative effect of these problems can result in decreased product yield and increased production costs.
[0006] To address the aforementioned technical problems, this utility model proposes an automatic grooving fixture for hardware products. Utility Model Content
[0007] The purpose of this utility model is to provide an automatic grooving fixture for hardware products, which can solve the above-mentioned technical problems.
[0008] The specific technical solution adopted by this utility model is as follows:
[0009] This utility model provides an automatic grooving fixture for hardware products, including an operating table and a linkage clamping mechanism and a flipping mechanism set on the operating table. The bottom surface of the operating table is equipped with an upward pushing mechanism for pushing the flipping mechanism.
[0010] The linkage clamping mechanism includes a push-pull plate and two clamping cylinders. The push-pull plate is cross-shaped. The piston rods of the two clamping cylinders are rotatably connected to two symmetrical sides of the push-pull plate. The cylinder bodies of the two clamping cylinders are respectively mounted on two fixing members. The fixing members are composed of bolts and nuts, and the nuts are welded to the bottom surface of the operating table. Both fixing members are mounted on the bottom surface of the operating table.
[0011] Two sets of linkage components are provided on the other two sides of the push-pull plate, and two sets of clamping components are provided on the bottom surface of the operating table. The two sets of clamping components are respectively connected to the two sets of linkage components.
[0012] Preferably, the linkage includes two linkage plates and two flip plates. The linkage plates and flip plates are both disposed on the bottom surface of the operating table. The confluence of the two linkage plates is rotatably connected to one side of the push-pull plate by a pin. The extension ends of the two linkage plates are rotatably engaged with one end of the two flip plates by pins respectively. A positioning shaft is fixedly provided on the bottom surface of the operating table. The positioning shaft is movably sleeved in a movable hole. The movable hole is opened at one-third of the length of the flip plate, and the connection point between the linkage plate and the flip plate is located at the far end of the movable hole.
[0013] Preferably, each set of clamping components includes two symmetrically arranged clamping units. Each clamping unit includes a sliding block and a plug cover. The sliding block is slidably fitted inside the sliding hole. The lower side of the sliding block is provided with a contraction part, and the inclined surface of the contraction part cooperates with the guide inclined surface inside the sliding hole. The bottom surface of the contraction part is threaded with an adjusting bolt.

[0015] Preferably, the flipping mechanism includes an inner plate and an upper flip plate. The inner plate is embedded in an inner hole, which is located on the operating table. The upper flip plate is disposed on the working surface of the operating table and is integrally formed with the inner plate. A hinge seat is installed on the operating table, and two rotating plates are rotatably mounted on the hinge seat. The upper ends of the two rotating plates are respectively fixed to the two sides of the bottom surface of the upper flip plate. The upper flip plate corresponds to the positions of two horizontally corresponding clamping units.
[0016] Preferably, the pushing mechanism includes a pushing cylinder, which is located below the operating table, and the piston rod of the pushing cylinder is connected to the bottom surface of the inner plate through a ball joint. The pushing cylinder is staggered with the linkage plate.
[0017] Preferably, the bottom surface of the operating table is provided with a support rod, the cylinder body of the upward push cylinder is sleeved on the support rod, and the two ends of the support rod are mounted on two fixing plates.

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0028] like Figure 1-5 As shown, an automatic grooving fixture for hardware products includes an operating table 1 and a linkage clamping mechanism 2 and a flipping mechanism 3 disposed on the operating table 1. An upward pushing mechanism 4 for pushing the flipping mechanism 3 is installed on the bottom surface of the operating table 1.
[0029] The linkage clamping mechanism 2 includes a push-pull plate 21 and two clamping cylinders 22. The push-pull plate 21 is cross-shaped. The piston rods of the two clamping cylinders 22 are rotatably connected to two symmetrical sides of the push-pull plate 21. The cylinder bodies of the two clamping cylinders 22 are respectively mounted on two fixing members 22a. The fixing members 22a are composed of bolts and nuts, and the nuts are welded to the bottom surface of the operating table 1. Both fixing members 22a are mounted on the bottom surface of the operating table 1. The clamping cylinders 22 are bidirectional cylinders with a working pressure range of 0.4-0.7MPa. The solenoid valve control end of the clamping cylinders 22 is electrically connected to the controller of the external device.
[0030] Two sets of linkage components are provided on the other two sides of the push-pull plate 21, and two sets of clamping components 26 are provided on the bottom surface of the operating table 1. The two sets of clamping components 26 are respectively connected to the two sets of linkage components.
[0031] As an optional implementation, the linkage includes two linkage plates 23 and two flip plates 24. Both linkage plates 23 and flip plates 24 are set on the bottom surface of the operating table 1. The confluence of the two linkage plates 23 is rotatably connected to one side of the push-pull plate 21 through a pin. The extension ends of the two linkage plates 23 are rotatably engaged with one end of the two flip plates 24 through pins respectively. A positioning shaft 25 is fixedly provided on the bottom surface of the operating table 1. The positioning shaft 25 is movably sleeved in the movable hole 24a. The movable hole 24a is opened at one-third of the length of the flip plate 24, and the connection point between the linkage plate 23 and the flip plate 24 is located at the far end of the movable hole 24a. This arrangement allows the flip plate 24 to rotate and adjust with the positioning shaft 25 as the fulcrum. At the same time, the position of the movable hole 24a can form a lever effect when the flip plate 24 rotates, thereby amplifying the thrust of the clamping cylinder 22.
[0032] See attached document Figure 3 and attached Figure 4 Each clamping unit 26 includes two symmetrically arranged clamping units. Each clamping unit includes a sliding block 261 and a plug cover 264. The sliding block 261 is slidably sleeved in the sliding hole 11. The lower side of the sliding block 261 is provided with a contraction part 262, and the inclined surface 11a of the contraction part 262 cooperates with the guide inclined surface 11a inside the sliding hole 11. The bottom surface of the contraction part 262 is threadedly connected with an adjusting bolt 263. The end of the flip plate 24 near the movable hole 24a is located below the contraction part 262 and is sleeved on the adjusting bolt 263. This arrangement allows the clamping unit to move along the sliding hole 11 when the flip plate 24 rotates, thereby realizing the clamping operation of the workpiece.
[0033] Furthermore, the plug cover 264 is installed on the working surface of the operating table 1. The plug cover 264 is plugged into the sliding block 261. The side of the plug cover 264 is provided with a clamping plate 265. The upper part of the operating table 1 is provided with a fastening bolt 266. The fastening bolt 266 passes through the plug cover 264 and is threadedly connected to the sliding block 261. This arrangement facilitates the replacement of plug covers 264 of different specifications to meet the clamping requirements of workpieces of different shapes.
[0034] See attached document Figure 5 The flipping mechanism 3 includes an inner plate 31 and an upper flipping plate 32. The inner plate 31 is embedded in an inner hole 12, which is located on the operating table 1. The upper flipping plate 32 is set on the working surface of the operating table 1 and is integrally formed with the inner plate 31. A hinge seat 34 is installed on the operating table 1. Two rotating plates 33 are rotatably mounted on the hinge seat 34. The upper ends of the two rotating plates 33 are respectively fixed to the two sides of the bottom surface of the upper flipping plate 32. The upper flipping plate 32 corresponds to the two clamping units in the lateral direction. The upper flipping plate 32 has a bent inclined surface 11a structure. This arrangement allows the inner plate 31 and the upper flipping plate 32 to flip and push the processed workpiece out of the operating table 1 under the action of the hinge seat 34. At the same time, the inclined surface 11a of the upper flipping plate 32 can drive the workpiece to avoid the clamping units during flipping, ensuring that the workpiece is smoothly released.
[0035] See attached document Figure 2 The push mechanism 4 includes a push cylinder 41, which is located below the operating table 1. The piston rod of the push cylinder 41 is connected to the bottom surface of the inner plate 31 by a ball joint. The push cylinder 41 is staggered with the linkage plate 23. This arrangement allows the push cylinder 41 to independently drive the inner plate 31 to complete the upward push operation.
[0036] Furthermore, the bottom surface of the operating table 1 is provided with a support rod 42, and the cylinder body of the upward push cylinder 41 is sleeved on the support rod 42. The two ends of the support rod 42 are installed on two fixing plates 43. The two fixing plates 43 are located on both sides of the upward push cylinder 41 and fixed to the bottom surface of the operating table 1. This arrangement allows the support rod 42 to provide stable support for the upward push cylinder 41 through the fixing plates 43, ensuring the stability of the upward push operation. The upward push cylinder 41 is a bidirectional cylinder with a working pressure range of 0.4-0.7MPa. The solenoid valve control end of the upward push cylinder 41 is electrically connected to the external controller.
[0037] Using the above structure, after the workpiece is placed on the working surface of the operating table 1, the controller activates the clamping cylinder 22. The cylinder piston rod pushes the cross-shaped push-pull plate 21 to move. The push-pull plate 21 drives the two sets of linkage components to move synchronously. The linkage plate 23 pushes the flipping plate 24 to rotate around the positioning shaft 25. The thrust is amplified through the lever principle. The flipping plate 24 drives the adjusting bolt 263 to move, so that the locking slider 261 slides along the sliding hole 11. The inclined surface 11a of the contraction part 262 cooperates with the guide inclined surface 11a of the sliding hole 11 to move the clamping unit towards the workpiece. The clamping plate 265 on the insertion cover 264... The automatic clamping of the workpiece is completed. After the grooving process is completed, the clamping cylinder 22 is reset and the clamping state is released. At the same time, the controller starts the upward pushing cylinder 41. The cylinder piston rod pushes the inner plate 31 to rise through the ball joint, which drives the one-piece upper flip plate 32 to rotate around the hinge seat 34. The upper flip plate 32 lifts the workpiece and flips it to an inclined state, so that the workpiece is released from the operating table 1 along the upper flip plate 32 to complete the unloading. The clamping force is uniform and stable throughout the process, and the unloading action is smooth and reliable. The entire process from clamping, processing to unloading is fully automated. The cooperation of each mechanism ensures processing efficiency and quality.
