Description

Technical Field

[0001] This utility model relates to the field of balance block processing technology, specifically a punching device for processing balance block parts. Background Technology

[0002] In the industrial manufacturing field, balance weights, as key counterweight components in rotating machinery, are widely used in equipment such as automobile engines, compressors, and precision instruments. The machining accuracy of their holes directly affects the dynamic balance performance and the overall machine operation stability.

[0003] According to CN223070265U, a punching device for forming a washing machine balance block is disclosed. This technology discloses a technical solution including "a base plate, with hydraulic telescopic rods fixedly installed on all four sides of the top of the base plate, and a housing set on the top of the output end of the four hydraulic telescopic rods". It has the technical effect of "moving two L-shaped positioning plates to both ends of the washing machine balance block by driving the output ends of two hydraulic cylinders, adjusting the distance between the two L-shaped positioning plates according to the washing machine balance block to clamp and fix it, and shifting the washing machine balance block clamped between the two L-shaped positioning plates when the output ends of the two hydraulic cylinders move in the same direction, and making the two L-shaped positioning plates made of rubber can protect the washing machine balance block when clamping it, preventing the washing machine balance block from being pinched by hard contact clamping, thereby enabling automatic adjustment of different positions for opening and protective fixing of washing machine balance blocks of different diameters".

[0004] In the existing process of punching balance block parts, the lack of a coordinated control separation and pushing mechanism often leads to uneven force and inaccurate positioning when the workpiece is pushed out, causing the workpiece to jam or deviate during the transmission process, which seriously affects the continuity and stability of the punching process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a punching device for processing balance block parts. Through precise timing control and coordinated actions, it achieves automatic separation and continuous pushing of workpieces, effectively eliminating the risk of jamming, ensuring a stable and efficient material supply process, and significantly improving the level of production automation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching device for processing balance block parts, comprising a processing table, wherein a processing mechanism is provided on the processing table for processing balance block parts, and the processing mechanism includes:

[0007] The main component is set on the machining table and used for punching the balance block parts;

[0008] The feeding assembly includes an extension frame fixed to the left side of the processing table, a main frame fixed to the top left side of the extension frame, a shaft rotatably mounted inside the upper part of the main frame, a servo motor installed inside the main frame to drive the shaft to rotate, a disc fixed to the top of the shaft, and several circumferentially arranged limit frames mounted on the top of the disc.

[0009] The discharge assembly includes a sub-frame fixed to the top right side of the extension frame. A base plate is longitudinally slidably mounted on the upper end of the sub-frame via a balance bar. A first cylinder is mounted on the upper end of the sub-frame and is used to drive the base plate to lift and lower. A guide rail is fixed on the top of the base plate. A slider is slidably mounted on the guide rail. A push head is fixed on the left end of the slider. A connector is fixed on the top of the slider. A second cylinder is mounted on the upper end of the main frame, and the left output end of the second cylinder is connected to the connector. A limit bracket is fixed on the top left side of the base plate.

[0010] Preferably, the processing mechanism further includes an auxiliary component disposed on the feeding assembly, including a mounting plate fixed to the right end of the main frame, a dual-axis cylinder mounted on the mounting plate, and a top head fixed to the output end above the dual-axis cylinder.

[0011] Preferably, the discharge assembly further includes inclined slots on both sides of the left end of the limiting bracket, and the inclined slots on both sides are arranged symmetrically.

[0012] Preferably, the feeding assembly includes a plurality of straight grooves arranged circumferentially on the disc, and slots are formed in the straight grooves.

[0013] Preferably, the main component includes a turntable mounted on the upper end of the processing table via a cam divider, a number of circumferentially arranged toolings fixed on the turntable, a gantry frame fixed at the rear end of the top of the processing table, a punching machine mounted on the gantry frame, and a pick-and-place mechanism mounted on the left side of the top of the processing table.

[0014] Preferably, the top of the top head is fixed with an anti-slip pad, the anti-slip pad is made of polyurethane and has dotted raised texture on its surface.

[0015] Beneficial effects

[0016] This invention provides a punching device for machining balance block parts. Compared with the prior art, it has the following advantages:

[0017] 1. A servo motor drives the shaft to rotate the disc intermittently, causing the workpieces stacked in the circumferentially arranged limiting frame to enter the waiting position on the unloading assembly in sequence. Then, the first cylinder drives the base plate to rise smoothly along the balance bar, so that the pusher head is accurately embedded in the straight groove of the disc. The second cylinder then drives the connecting part to drive the slider to slide to the right along the guide rail. The pusher head reliably pushes the workpiece onto the supporting surface of the limiting bracket, ensuring that the picking and placing mechanism can efficiently and reliably grab the workpiece. This realizes the full automation of the process from workpiece separation from the stockpile, positioning to pushing, which greatly improves the feeding efficiency and cycle consistency.

[0018] 2. When the pusher pushes out the bottom workpiece and the workpiece has not yet completely left the limit frame and entered the support range of the limit bracket, the dual-axis cylinder immediately drives the top head to move upward, lifting the upper workpiece stacked inside the limit frame as a whole; effectively eliminating the risk of jamming caused by the upper workpiece falling instantly due to its own weight after the bottom workpiece is pulled out, and avoiding possible frictional interference between the workpiece stack and the inner wall of the limit frame.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a punching device for processing balance block parts, including a processing table 1, on which a processing mechanism 2 is provided for processing balance block parts, the processing mechanism 2 including:

[0028] The main component 21 is set on the machining table 1 and is used for punching the balance block parts;

[0029] The feeding assembly 22 includes an extension frame 221 fixed on the left side of the processing table 1. A main frame 222 is fixed on the top left side of the extension frame 221. A shaft 223 is rotatably mounted inside the upper part of the main frame 222. A servo motor 224 is installed inside the main frame 222 and is used to drive the shaft 223 to rotate. A disc 225 is fixed on the top of the shaft 223. Several circumferentially arranged limit frames 228 are installed on the top of the disc 225.

[0030] The discharge assembly 23 includes a sub-frame 231 fixed to the top right side of the extension frame 221. A base plate 234 is longitudinally slidably mounted on the upper end of the sub-frame 231 via a balance bar 232. A first cylinder 233 is mounted on the upper end of the sub-frame 231 and is used to drive the base plate 234 to lift. A guide rail 235 is fixed on the top of the base plate 234. A slider 236 is slidably mounted on the guide rail 235. A push head 237 is fixed on the left end of the slider 236. A connector 238 is fixed on the top of the slider 236. A second cylinder 239 is mounted on the upper end of the main frame 222, and the left output end of the second cylinder 239 is connected to the connector 238. A limit bracket 2310 is fixed on the top left side of the base plate 234.

[0031] In this embodiment, the servo motor 224 drives the shaft 223 to rotate the disc 225 intermittently, causing the workpieces stacked in the circumferentially arranged limiting frame 228 to enter the waiting position on the unloading assembly 23 in sequence. Then, the first cylinder 233 drives the base plate 234 to rise smoothly along the balance bar 232, so that the push head 237 is accurately embedded in the straight groove 226 of the disc 225. The second cylinder 239 then drives the connector 238 to drive the slider 236 to slide to the right along the guide rail 235. The push head 237 reliably pushes the workpiece onto the supporting surface of the limiting bracket 2310, ensuring that the picking and placing mechanism 215 can efficiently and reliably grab the workpiece. This realizes the full automation of the process from workpiece separation from the stockpile, positioning to pushing, which greatly improves the feeding efficiency and cycle consistency.

[0032] Specifically, the processing mechanism 2 also includes an auxiliary component 24 set on the feeding component 22, including a mounting plate 241 fixed to the right end of the main frame 222, a dual-axis cylinder 242 mounted on the mounting plate 241, and a top head 243 fixed above the output end of the dual-axis cylinder 242.

[0033] In this embodiment, when the pusher 237 pushes out the bottom workpiece and the workpiece has not yet completely left the limiting frame 228 and entered the supporting range of the limiting bracket 2310, the dual-axis cylinder 242 immediately drives the top head 243 to move upward, lifting the upper workpiece stacked inside the limiting frame 228 as a whole; effectively eliminating the risk of jamming caused by the upper workpiece falling instantly due to its own weight after the bottom workpiece is pulled out, and avoiding possible frictional interference between the workpiece stack and the inner wall of the limiting frame 228.

[0034] Specifically, the discharge assembly 23 also includes inclined slots 2311 on both sides of the left end of the limiting bracket 2310, and the inclined slots 2311 on both sides are arranged symmetrically.

[0035] In this embodiment, when the pusher 237 pushes the workpiece horizontally out of the limit bracket 228, the workpiece first contacts the inclined inner wall of the inclined slot 2311; as the pushing action continues, the inclined wall will guide and correct the workpiece, guiding the workpiece to automatically center and smoothly slide into the supporting plane of the limit bracket 2310.

[0036] Specifically, the feeding assembly 22 includes a number of straight grooves 226 arranged circumferentially on the disc 225, and slots 227 are provided on the straight grooves 226.

[0037] In this embodiment, when the pusher 237 performs the pushing action, the straight groove 226 provides a precise embedding channel, ensuring that the pusher 237 can directly contact and push the workpiece without avoiding the main body structure of the disk 225, completely avoiding motion interference between the pusher 237 and the disk 225; at the same time, when the dual-axis cylinder 242 of the auxiliary component 24 drives the top head 243 to rise to lift the workpiece stack, the slot 227 provides an unobstructed rising path for the top head 243, allowing the top head 243 to pass smoothly through the disk 225 and lift the workpiece, effectively avoiding motion interference between the top head 243 and the disk 225.

[0038] Specifically, the main component 21 includes a turntable 211 mounted on the upper end of the processing table 1 via a cam divider, a number of circumferentially arranged tooling 212 fixed on the turntable 211, a gantry frame 213 fixed at the rear end of the top of the processing table 1, a punching machine 214 mounted on the gantry frame 213, and a pick-and-place mechanism 215 mounted on the left side of the top of the processing table 1.

[0039] In this embodiment, the pick-and-place mechanism 215 transfers the workpiece that has been positioned on the limiting bracket 2310 to the tooling 212 on the turntable 211. Then, the cam divider drives the turntable 211 to perform precise indexing rotation, and transports the tooling 212 carrying the workpiece to the processing station below the gantry 213, so that the workpiece is accurately located directly below the punching of the punching machine 214 to complete the punching process.

[0040] Specifically, the top of the top of the top 243 is fixed with an anti-slip pad. The anti-slip pad is made of polyurethane and has dotted raised texture on its surface.

[0041] In this embodiment, when the dual-axis cylinder 242 drives the top head 243 to rise and lift the workpiece stack, the anti-slip pad can ensure that the workpiece stack will not slide or shift during the lifting process, and also avoid scratching the workpiece surface.

[0042] The working principle and usage process of this utility model are as follows: First, the servo motor 224 drives the shaft 223 to drive the disc 225 to rotate intermittently, so that the workpieces stacked in the circumferentially arranged limiting frame 228 enter the waiting position on the unloading component 23 in sequence; then, the first cylinder 233 drives the base plate 234 to rise steadily along the balance bar 232, so that the push head 237 is accurately embedded in the straight groove 226 of the disc 225; the second cylinder 239 then drives the connecting piece 238 to drive the slider 236 to slide to the right along the guide rail 235, and the push head 237 reliably pushes the workpiece onto the supporting surface of the limiting bracket 2310, ensuring that the picking and placing mechanism 215 can efficiently and reliably grab the workpiece; the entire process of workpiece separation, positioning and pushing from the material pile is automated, which greatly improves the feeding efficiency and cycle consistency;

[0043] Meanwhile, when the pusher 237 pushes out the bottom workpiece and the workpiece has not yet completely left the limit frame 228 and entered the support range of the limit bracket 2310, the dual-axis cylinder 242 immediately drives the top head 243 to move upward, lifting the upper workpiece stacked inside the limit frame 228 as a whole; effectively eliminating the risk of jamming caused by the upper workpiece falling instantly due to its own weight after the bottom workpiece is pulled out, and avoiding possible frictional interference between the workpiece stack and the inner wall of the limit frame 228;

[0044] Finally, the pick-and-place mechanism 215 transfers the workpiece that has been positioned on the limit bracket 2310 to the fixture 212 on the turntable 211. Then, the cam divider drives the turntable 211 to perform precise indexing rotation, and transports the fixture 212 carrying the workpiece to the processing station below the gantry 213, so that the workpiece is accurately located directly below the punching of the punching machine 214 to complete the punching process.
