Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, specifically a machining device for thermostat glands. Background Technology

[0002] A car thermostat, also known as a throttle, is a valve that controls the flow path of coolant. As an automatic temperature regulating device, it typically contains a temperature-sensing component that opens or closes the flow of air, gas, or liquid through expansion or contraction. Its function is to automatically adjust the amount of water entering the radiator based on the engine coolant temperature, changing the water circulation range to regulate the cooling system's heat dissipation capacity and ensure the engine operates within a suitable temperature range.

[0003] As a core component of the temperature control system, the thermostat's cover is made from brass rods through multiple precision processes. By sequentially drawing, drilling, and polishing one end of the brass rod, a semi-finished blank can be obtained. Further finishing of the semi-finished blank yields the automotive thermostat cover.

[0004] Existing capping rough processing equipment has obvious limitations: First, a single machine can only complete one process, which requires multiple machines to work together. This not only significantly reduces the overall production efficiency, but also significantly increases production costs due to equipment purchase and maintenance, site occupation, and other factors. Second, existing equipment lacks continuous feeding function, which requires frequent manual handling and feeding, which is both time-consuming and labor-intensive, further restricting the improvement of production efficiency. Utility Model Content

[0005] To address the problems of existing processing equipment having limited functionality, resulting in multiple pieces of equipment, increased purchase, maintenance, and floor space costs, inability to continuously and automatically feed materials, reliance on frequent manual handling and material replenishment, high labor costs, and low efficiency, this utility model provides a machining device for thermostat caps.

[0006] This utility model is achieved through the following technical solution:

[0007] A machining device for thermostat caps includes a worktable, a housing connected to the worktable, a spindle rotatably connected to the housing, a pneumatic chuck connected to the outside of the spindle, and through holes for bar stock to pass through the spindle and the pneumatic chuck shafts. A motor is connected to the worktable and connected to the spindle via a belt drive. A slide table that can move back, forth, left, and right is connected to one side of the worktable, and a feeding mechanism that can feed bar stock into the pneumatic chuck is connected to the other side. A tool set and a pulling device are connected to the slide table.

[0008] The feeding mechanism includes a fixed frame connected to and installed on the workbench, a feeding device connected to and installed on the fixed frame, a rotating shaft rotatably connected to the inner side of the fixed frame, a servo motor that drives the rotating shaft to rotate connected to the outer side of the fixed frame, a hopper connected to and installed on the upper side of the fixed frame, and several discs connected to and installed on the rotating shaft. The discs are provided with grooves that can transport the bar material in the hopper to the feeding device.

[0009] A further improvement of this utility model is that the material pulling device includes a bracket and a cylinder connected and installed on the slide table. Two clamping plates are rotatably connected and installed inside the bracket, and a cone block that can push the clamping plates to clamp the bar material is connected and installed at the output end of the cylinder.

[0010] A further improvement of this utility model is that the feeding device includes two sets of support plates respectively connected and installed on both sides of the fixed frame. A conveyor roller is rotatably connected between each set of support plates. The two conveyor rollers are connected by a conveyor belt. A second motor that drives the conveyor rollers to rotate is connected and installed on the outside of the support plates. A limiting frame for receiving the bar material and aligning the bar material with the through hole of the main shaft is also connected and installed on the fixed frame.

[0011] A further improvement of this utility model is that a guide frame is connected and installed on the fixing frame, which allows the bar stock to pass through and be guided into the through hole of the main shaft.

[0012] A further improvement of this utility model is that the through hole of the guide frame is tapered.

[0013] A further improvement of this utility model is that the tool set includes a positioning drill, a hole drill, and a turning tool connected and mounted on the slide.

[0014] A further improvement of this utility model is that the conveyor belt is provided with several protrusions.

[0015] A further improvement of this utility model is that a bearing is provided inside the guide frame.

[0016] A further improvement of this invention is that the cross-sectional shape of the hopper is set to S-shape.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] In operation, a fixed-length bar stock is placed into the hopper. The servo motor is started, driving a rotating disc via a shaft to transfer the bar stock to the feeding device. The feeding device then transports the bar stock to a pneumatic chuck for clamping. The motor, via a belt, drives the main shaft, causing the pneumatic chuck to rotate. The bar stock then rotates, and the slide moves back, forth, left, and right, driving the cutter set to drill holes and polish the outer diameter of the bar stock. The entire blank is then turned off. The main shaft stops rotating, and the pulling device is activated to pull the bar stock to the corresponding cutting position for the next blank processing. After the entire bar stock is processed, the feeding mechanism is restarted for reloading. This device achieves continuous automated feeding and processing of multiple processes through the feeding mechanism and the cutter set on the slide, improving production efficiency and automation, reducing production costs, saving equipment space, and improving processing accuracy by processing multiple processes in a single clamping operation.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] like Figure 1-6 As shown, a machining apparatus for thermostat caps includes a worktable 1 (with... Figure 1 The arrangement is in the left-right-front-back direction). A housing 2 is connected and installed on the worktable 1. A main shaft 3 is rotatably connected and installed on the housing 2 through two opposite tapered roller bearings to improve axial bearing capacity. A pneumatic chuck 4 is connected and installed on the outside of the main shaft 3. Both the main shaft 3 and the pneumatic chuck 4 have through holes for the bar to pass through. A motor 5 is connected and installed on the worktable 1 and inside the housing 2. The motor 5 and the main shaft 3 are equipped with pulleys. The motor 5 and the main shaft 3 are connected and driven by a belt 6. A slide table 7 is connected and installed on one side of the worktable 1. It can move and adjust along the precision guide rail. Two sets of servo motors drive the ball screw to rotate so that the slide table 7 can move precisely along the guide rail, ensuring that the direction and size of the slide table 7's displacement are accurate. A feeding mechanism 8 that can feed the bar into the pneumatic chuck 4 is connected and installed on the other side. A knife set 9 and a pulling device 10 that can pull the bar back to the processing position are connected and installed on the slide table 7.

[0029] The feeding mechanism 8 includes a fixed frame 81 connected and installed on the workbench 1. A feeding device 82 is connected and installed on the fixed frame 81. A rotating shaft 83 is rotatably connected and installed on the inner side of the fixed frame 81. A servo motor 84 that drives the rotating shaft 83 to rotate is connected and installed on the outer side of the fixed frame 81. A hopper 85 is connected and installed on the upper side of the fixed frame 81. Several discs 86 are connected and installed on the rotating shaft 83. The discs 86 are provided with grooves 87 that can transport the bar material in the hopper 85 to the feeding device 82.

[0030] In use, a fixed-length bar is placed into the hopper 85. The servo motor 84 is started, which drives the disc 86 to rotate via the shaft 83, causing the bar in the hopper 85 to fall into the groove 87. As the disc 86 continues to rotate, it is transferred to the feeding device 82. Each time the disc 86 rotates only once, it feeds only one bar. The feeding device 82 transports the bar to the pneumatic chuck 4 for clamping. The motor 5 drives the main shaft 3 via the belt 6, causing the pneumatic chuck 4 to rotate. Then the bar rotates. The servo motor drives the ball screw to rotate, precisely pushing the slide table 7 to move back and forth and left and right, driving the cutter group 9 to drill holes and polish the outer diameter of the bar. Then the entire blank is turned off. The main shaft 3 is stopped, and the pulling device 10 is started. Driven by the slide table 7, the bar is pulled to the corresponding cutting position for the next cap blank processing. After the entire bar is processed, the feeding mechanism 8 is restarted for feeding. This device achieves continuous automated feeding and production, as well as processing multiple processes in a single setup, through the feeding mechanism 8 and the tool group 9 on the slide table 7. This improves production efficiency and processing accuracy, reduces production costs, and saves the space required for multiple processing operations.

[0031] It should be noted that bar stock machining generates a large amount of heat, requiring the use of circulating coolant for cooling to prevent tool overheating and wear, premature damage to the cutting edge, reduced tool life, and increased operating costs. The coolant must contain specific additives to prevent corrosion of the bar stock and tools. To prevent debris from flying around and causing injury during cutting, the machining area needs protection, including sliding guards and transparent observation ports. Finished cap blanks are placed under the pneumatic chuck 4 for easy collection. To prevent the belt 6 from bending the spindle 3, a support sleeve can be fitted over the outside of the spindle 3. The support sleeve is fixed to the housing 2, and a pulley is rotatably connected to the support sleeve. The pulley has a spline on its inner side, and the spindle 3 has a spline groove that mates with the spline, driving the spindle 3 to rotate. This prevents the belt tension from being transmitted to the spindle 3, ensuring its accuracy.

[0032] The material pulling device 10 includes a bracket 101 and a cylinder 102 connected and installed on the slide table 7. Two clamping plates 103 are rotatably connected and installed inside the bracket 101. The middle shaft of the two clamping plates 103 can rotate on the bracket 101, so that the clamping plates 103 rotate around its center on the horizontal plane. The output end of the cylinder 102 is connected and installed with a cone block 104 that can push the clamping plates 103 to clamp the bar material. When the cone block 104 moves forward, as its contact diameter with the clamping plates 103 increases, it will push the clamping plates 103 on the side closer to the cone block 104 to separate, that is, to make the clamping plates 103 rotate. Then the clamping plates 103 on the side away from the cone block 104 will close and clamp the bar material. After the spindle 3 stops rotating, the pneumatic chuck 4 releases, the slide 7 moves towards the pneumatic chuck 4, the starting cylinder 102 extends, the cone block 104 pushes the clamping plate 103 to rotate, clamping the bar stock. The slide 7 moves back to pull the bar stock to the cutting position, the cylinder 102 retracts to release the clamping plate 103, and at the same time the pneumatic chuck 4 clamps the bar stock and rotates it for processing again. By using the slide 7 to drive the clamping plate 103 to clamp the bar stock for pulling, it can accurately pull the bar stock of the required length. It is fast, efficient, and has a stable and reliable clamping force. It can also pull out the bar stock as much as possible, making full use of the bar stock and saving costs.

[0033] The feeding device 82 includes two sets of support plates 821 respectively connected and installed on both sides of the fixed frame 81. Each set of support plates 821 is rotatably connected to a conveyor roller 822, and the two conveyor rollers 822 are connected by a conveyor belt 823. A second motor 824 for driving the conveyor rollers 822 is connected and installed on the outside of the support plates 821. A limiting frame 825 for receiving bar stock and aligning the bar stock with the through hole of the main shaft 3 is also connected and installed on the fixed frame 81. When the second motor 824 is started, it drives the conveyor belt 823 to rotate through the conveyor rollers 822. The limiting frame 825 limits the bar stock from the hopper 85, so that the axial direction of the bar stock is aligned with the through hole of the main shaft 3. The conveyor belt 823 will convey the bar stock to the pneumatic chuck 4, push out the excess material after processing the previous bar stock, and the new bar stock will continue to slide forward until it hits the bracket 101 of the pulling device 10 to determine the length. Then the feeding device 82 stops operating, which can continuously feed bar stock and improve processing efficiency.

[0034] The fixed frame 81 is connected to a guide frame 11 that allows the bar stock to pass through and be guided into the through hole of the main shaft 3. The guide frame 11 can provide support for the bar stock and prevent low-rigidity materials from deflecting and deforming after being suspended for a long distance, thus affecting their entry into the through hole of the main shaft 3. It can adapt to the processing of materials of different specifications.

[0035] The guide frame 11 has a tapered through-hole with a larger inlet and a smaller outlet. This allows the bar stock to enter the main shaft 3 and the pneumatic chuck 4 more smoothly, and enables the bar stock to enter the through-hole of the guide frame 11 for guidance more easily.

[0036] The tool set 9 includes a positioning drill 91, a hole drill 92, and a turning tool 93, all mounted on the slide table 7. The positioning drill 91 pre-drills positioning holes on the workpiece surface to ensure that subsequent drilling is precisely aligned with the predetermined position. It also reduces the wear of the hole drill 92 and extends the tool's service life. The turning tool can turn the outer diameter to obtain the required cylindricity and surface roughness, and can also cut off the machined gland blank, greatly saving time during tool changes and improving efficiency.

[0037] The conveyor belt 823 has several protrusions 8231. These protrusions increase the friction between the conveyor belt and the bar stock, preventing slippage and improving the conveying capacity.

[0038] The guide frame 11 is equipped with a bearing 111. When the bar rotates, it reduces the friction between the bar and the guide frame 11, and makes the inner ring of the bearing 111 rotate with the bar, thus preventing excessive wear on the bar and affecting the surface quality.

[0039] The hopper 85 has an S-shaped cross-section. This ensures that the bar stock can move automatically downwards under gravity, allowing the hopper 85 to maintain its height without increasing its overall height. This provides a suitable height for workers to add bar stock, accommodating and storing more bar stock and reducing the frequency of material additions.

[0040] In use, the bar stock is fed into the hopper 85 for storage. The servo motor 84 is started to drive the disc 86 to rotate. When the groove 87 is aligned with the hopper 85, the bottom bar stock will be stuck into the groove 87. As the disc 86 rotates, it falls into the feeding device 82. The servo motor 84 stops rotating, and the bar stock in the hopper 85 moves down, waiting for continued feeding. The limit frame 825 straightens the bar stock so that it is aligned with the through hole of the spindle 3. The second motor 824 is started to drive the conveyor belt 823 to rotate, conveying the bar stock to the pneumatic chuck 4. The slide table 7 moves to align the bracket 101 with the bar stock for positioning length. The pneumatic chuck 4 is started to clamp the bar stock. The first motor 5 rotates and drives the spindle 3 to rotate through the belt 6. The slide table 7 drives the tool set 9 to adjust its position back and forth and then feed for machining, realizing positioning, drilling, and rounding. Finally, the turning tool 9... 3. The bar stock is fed radially to cut off the cap blank. Then, the pulling mechanism 10 is aligned with the bar stock, and the cylinder 102 is activated to drive the cone block 104 to push out. The clamping plate 103 rotates around the bracket 101 to clamp the bar stock. With the movement of the slide table 7, the bar stock is pulled out to the designated processing position to continue processing. When the entire bar stock is about to be processed, the feeding device 82 is restarted to feed the new bar stock. The new bar stock pushes out the remaining material of the previous bar stock, and the pneumatic chuck 4 re-clamps the bar stock for processing. Through the cooperation of the feeding mechanism 8 and the knife group 9 on the slide table 7, continuous automated feeding production and processing of multiple processes are realized, which improves the production efficiency and automation level, reduces the production cost, saves the equipment space, and processes multiple processes in one clamping, thus improving the processing accuracy.

[0041] The controller can be a common PLC controller, such as the Siemens S7-200+ series. It can operate continuously and automatically by setting the program, so that the feeding mechanism 8, the bar processing and the pulling mechanism 10 operate according to the predetermined rhythm. Each time the bar position is adjusted, the rotation of the spindle 3 needs to be stopped. Each time the bar is fed, the servo motor 84 rotates only once to ensure that there is only one bar on the feeding device 82. The number of processing times is determined according to the length of the bar, and the corresponding processing program is determined.
