Description

Technical Field

[0001] This utility model belongs to the technical field of bar stock feeding equipment, specifically a feeding device for the tailstock of an automotive thermostat. 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] The thermostat is composed of many parts, one of which is the tailstock. The tailstock is made of brass rods through multiple processes. The first step is to cut the brass rods to obtain the required blanks. Not only the tailstock, but almost all parts related to the short shaft have a rod cutting process.

[0004] Currently, in small-scale production, the cutting of metal bars is usually done using traditional methods, which require manual feeding and machine operation. This method cannot achieve continuous automated production and suffers from low material utilization, low production efficiency, high energy consumption, poor cross-sectional quality, and low dimensional accuracy, resulting in increased production costs. Utility Model Content

[0005] To address the problems of existing automotive thermostat tailstock unloading devices, such as the inability to achieve continuous automated production, low production efficiency, high labor intensity of manual operation, and high production costs, this utility model provides an automotive thermostat tailstock unloading device.

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

[0007] A feeding device for the tailstock of an automotive thermostat includes a fixed frame and a cutting mechanism. A motor and a speed-changing mechanism connected to the motor are mounted on the fixed frame. A cylindrical cam is mounted on the output end of the speed-changing mechanism. A rotating seat is mounted on the fixed frame, and a lever is rotatably mounted on the rotating seat. One end of the lever has a guide post that is slidably connected to the cylindrical cam groove.

A second guide post is located on the other side of the lever. A guide groove for the second guide post to slide in is provided on the guide rail plate. A feeding mechanism capable of intermittent feeding is mounted on the output end of the speed-changing mechanism.

[0008] A further improvement of this utility model is that the feeding mechanism includes a drive gear connected and installed at the output end of the transmission mechanism. The drive gear is connected to the output end of the transmission mechanism via an automatic clutch. A vertical plate is provided on the side of the fixed frame away from the cylindrical cam. Several sets of vertically paired shafts are rotatably connected and installed on the vertical plate. Gears are connected and installed on the inner side of each shaft. The gears on the two shafts in each set mesh with each other. A shaft is rotatably connected and installed on the vertical plate between adjacent sets of shafts. A gear that meshes with the adjacent gear is connected and installed on one side of the shaft. A driven gear that meshes with the drive gear is connected and installed on the other side of the shaft. A grooved wheel is connected and installed on the outer side of the shaft. A support plate through which the bar can pass is connected and installed on the vertical plate.

[0010] A further improvement of this utility model is that the speed change mechanism includes a first pulley mounted on a motor and a housing embedded in a fixed frame. An input shaft is rotatably mounted on the bottom side wall of the housing, and a first bevel gear is mounted on the inner side of the input shaft. A partition is provided inside the housing, and an intermediate shaft perpendicular to the input shaft is rotatably mounted on the partition. A second bevel gear meshing with the first bevel gear is mounted on the lower end of the intermediate shaft, and a third bevel gear is mounted on the upper end of the intermediate shaft. An output end perpendicular to the input shaft and the intermediate shaft is rotatably mounted on the upper side wall of the housing, and a fourth bevel gear meshing with the third bevel gear is mounted on the output end. A second pulley is mounted on the other end of the input shaft, and the second pulley is connected to the first pulley via a first belt drive.

[0011] A further improvement of this utility model is that it also includes a water storage tank connected and installed on the side of the fixed frame, a water pump that can draw out the coolant in the water storage tank is connected and installed on the water storage tank, and a water delivery pipe that can inject coolant onto the saw blade is connected and installed at the outlet of the water pump.

The bar to be cut is placed into the feeding mechanism, which transports the bar to the cutting mechanism. The guide plate drives the cutting mechanism to reciprocate for cutting, and the feeding mechanism controls the cutting size. This device, through the cooperation of the cutting mechanism and the feeding mechanism, achieves continuous automated production, improves production efficiency, reduces labor intensity, improves production accuracy, and reduces production costs.

[0030] 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.

[0031] like Figure 1-9As shown, a tailstock feeding device for an automotive thermostat includes a fixed frame 1 and a cutting mechanism 100. A motor 12 is connected and installed on the lower side of the fixed frame 1. A speed change mechanism 14 is driven and installed on the output shaft of the motor 12. A cylindrical cam 17 is connected and installed on the output end of the speed change mechanism 14. A rotating seat 18 is connected and installed on the fixed frame 1. A lever 19 is rotatably connected and installed on the rotating seat 18. One end of the lever 19 is provided with a guide post 20 that is slidably connected to the groove of the cylindrical cam 17. A guide groove plate 2 is connected and installed on the upper side of one side of the fixed frame 1. A guide rail plate 3 that is slidably nested with the guide groove plate 2 is connected and installed on the cutting mechanism 100. A second guide post 201 is provided on the other side of the lever 19. A guide groove 202 for the second guide post 201 to slide and connect is provided on the lower end of the guide rail plate 3. A feeding mechanism 200 that can intermittently feed the material according to the cutting frequency is connected and installed on the output end of the speed change mechanism 14.

[0032] In operation, motor 12 and cutting mechanism 100 are started. Motor 12 drives cylindrical cam 17 to rotate via speed change mechanism 14. The rotating cylindrical cam 17 drives lever 19 to swing back and forth around rotating seat 18, causing guide rail plate 3 to slide back and forth on guide groove plate 2. The bar to be cut is placed into feeding mechanism 200, which transports the bar to cutting mechanism 100. Guide rail plate 3 drives cutting mechanism 100 to reciprocate and cut the bar. Feeding mechanism 200 controls the cutting size. This device uses rotating cylindrical cam 17 to drive cutting mechanism 100 to reciprocate and cut. Feeding mechanism 200 continuously feeds the bar in rhythm, realizing continuous automated bar feeding production, improving production efficiency. Operators only need to put the bar into feeding mechanism to complete the feeding, reducing labor intensity, improving production accuracy, and reducing production costs.

[0033] In one embodiment, the feed mechanism 200 includes a drive gear 21 connected and installed on the side of the output end of the transmission mechanism 14 away from the cylindrical cam 17. The drive gear 21 is connected to the output end of the transmission mechanism 14 via an automatic clutch 53. A vertical plate 22 is provided on the side of the fixed frame 1 away from the cylindrical cam 17. Several sets of vertically paired shafts 23 are rotatably connected and installed on the vertical plate 22. Gears 24 are connected and installed on the inner side of each shaft 23. The gears 24 on the two shafts 23 in each set are mutually... The two shafts are rotatably connected to the vertical plate 22 between adjacent shafts 23. A gear 26 that meshes with the adjacent gear 24 is connected to one side of shaft 25, and a driven gear 27 that meshes with the driving gear 21 is connected to the other side of shaft 25. A grooved wheel 29 is connected to the outside of shaft 23. A support plate 28 through which the bar can pass is connected to the vertical plate 22. Bolts 30 are connected to the support plate 28, and a baffle 31 fixed by two nuts is connected to the bolts 30. The speed change mechanism 14 drives the gear to rotate, which in turn causes the grooved wheel 29 to rotate, driving the bar stock to be conveyed to the cutting mechanism 100. The automatic clutch 53 can engage and disengage the power output of the speed change mechanism 14. When the cutting mechanism 100 retracts, the automatic clutch 53 engages, causing the grooved wheel 29 to rotate and drive the bar stock. When the bar stock touches the baffle 31, the bar stock stops moving forward, thus ensuring the size of the cut bar stock. The grooved wheel 29 will continue to rotate to prevent the bar stock from rebounding. The cutting mechanism 100 moves forward to cut. Through the connection and cooperation of the above components, the timing of bar stock feeding and cutting is coordinated to achieve continuous and automated feeding.

[0034] In another embodiment, the feed mechanism 200 includes a drive gear 21 connected and installed on the side of the output end of the transmission mechanism 14 away from the cylindrical cam 17. The drive gear 21 is a non-complete gear with a certain angle of teeth. A vertical plate 22 is provided on the side of the fixed frame 1 away from the cylindrical cam 17. Several sets of vertically paired shafts 23 are rotatably connected and installed through the vertical plate 22. Gears 24 are connected and installed on each shaft 23 inside the vertical plate 22. A shaft 25 is rotatably connected and installed on the vertical plate 22 between every two sets of shafts 23. A gear 26 that meshes with the adjacent gear 24 is connected and installed on one side of the shaft 25. A driven gear that meshes with the drive gear 21 is connected and installed on the other side of the shaft 25. The driven gear 27 has evenly distributed arc-shaped protrusions corresponding to the number of teeth of the driving gear 21. This allows the driving gear 21 to rotate the driven gear 27 by a certain angle, and then the next arc-shaped protrusion will be locked onto the toothless surface of the driving gear 21. Only when the toothed part of the driving gear 21 approaches can the driven gear 27 continue to rotate. A grooved wheel 29 that can hold the bar is connected and installed on the outside of the shaft 23. A support plate 28 through which the bar can pass is connected and installed on the vertical plate 22. Bolts 30 are connected and installed on the support plate 28. A baffle 31 fixed by two nuts is connected and installed on the bolts 30. The feed mechanism 200 is equipped with a housing that can protect the gear set from dust and debris. The bar stock is placed between the upper and lower grooved wheels 29, which clamp the bar stock. The output end of the speed change mechanism 14 drives the cylindrical cam 17 to rotate. When the cylindrical cam 17 rotates to the point where the guide rail 3 moves away from the bar stock, and when the cutting mechanism 100 is not cutting the bar stock, the drive gear 21 meshes with the driven gear 27, starting to drive the grooved wheels 29 to rotate. The grooved wheels 29 clamping the bar stock feed the bar stock to the cutting mechanism 100. The baffle 31 can prevent the bar stock from moving further forward, ensuring that the length of the bar stock is the same for each feed. When the cylindrical cam 17 rotates to the point where the guide rail 3 moves away from the bar stock, and the cutting mechanism 100 is not cutting the bar stock, the drive gear 21 meshes with the driven gear 27, starting to drive the grooved wheels 29 to rotate. The grooved wheels 29 clamping the bar stock feed the bar stock to the cutting mechanism 100. The baffle 31 can prevent the bar stock from moving further forward, ensuring that the length of the bar stock is the same for each feed. When the cam 17 drives the guide plate 3 to move closer to the bar stock, and before the cutting mechanism 100 touches the bar stock, the drive gear 21 and the driven gear 27 mesh. Since the driven gear 27 has a protrusion that matches the arc of the drive gear 21, the driven gear 27 stops rotating after meshing, preparing for the next meshing, preventing interference between the drive gear 21 and the driven gear 27 during meshing. Through the connection and cooperation of the above components, the timing of bar stock feeding and cutting is coordinated, and continuous automated feeding is achieved.

[0035] The cutting mechanism 100 includes a motor frame 4 mounted on a guide rail plate 3, a second motor 5 mounted on the motor frame 4, a third pulley 6 driven by the output end of the second motor 5, a shaft frame 7 mounted on the other side of the guide rail plate 3, a third shaft 8 rotatably mounted inside the shaft frame 7, a fourth pulley 9 mounted on one side of the third shaft 8, and the third pulley 6 and the fourth pulley 9 connected by a second belt 10. A saw blade 11 is mounted on the other side of the third shaft 8. The second motor 5 drives the saw blade 11 to rotate at high speed through the third pulley 6, the second belt 10, the fourth pulley 9, and the third shaft 8 in sequence. The saw blade 11 needs to be replaced regularly to prevent insufficient diameter of the saw blade 11 from failing to cut the bar stock. The high-speed rotating saw blade 11 has a good cutting speed and good cut surface quality, which can improve the cutting efficiency and quality.

[0036] The transmission mechanism 14 includes a first pulley mounted on the motor 12 and a housing 32 mounted on the fixed frame 1. An input shaft 33 is rotatably mounted on the bottom side wall of the housing 32. A first bevel gear 34 is mounted inside the input shaft 33. A partition 35 is provided inside the housing 32. An intermediate shaft 36, perpendicular to the input shaft 33, is rotatably mounted on the partition 35. The lower end of the intermediate shaft 36 is rotatably connected to the housing 32 via a thrust bearing, providing support for the intermediate shaft and preventing contact between the bevel gears. The intermediate shaft 36 is connected to a second bevel gear 37 that meshes with the first bevel gear 34 at its lower part, and a third bevel gear 38 is connected to the upper end of the intermediate shaft 36. An output end 330, perpendicular to the input shaft 33 and the intermediate shaft 36, is rotatably connected to the upper side wall of the housing 32. A fourth bevel gear 39, meshing with the third bevel gear 38, is connected to the output end 330. A second pulley 15 is connected to the other end of the input shaft 33, and the second pulley 15 is connected to the first pulley 13 via a first belt 16. The meshing bevel gears change the direction of torque transmission. Simultaneously, the smaller bevel gear drives the larger bevel gear, reducing the speed to the required level and increasing the torque, allowing the output end 330 to output a larger torque, enabling long-distance power output and ensuring adequate installation space for each component.

[0037] The system also includes a water tank 40 connected to and installed on the side of the mounting frame 1. A water pump 41 is connected to the water tank 40 and is capable of drawing out the coolant from the water tank 40. The outlet of the water pump 41 is connected to a water pipe 42 that injects coolant into the saw blade 11. The water pump 41 draws out the coolant from the water tank 40 and delivers it to the cutting position between the saw blade 11 and the bar stock through the water pipe 42 to cool down the cutting process and prevent the saw blade 11 from overheating, affecting the cutting quality, and causing damage to the saw blade 11.

[0038] The support plate 28 is connected to a guide sleeve 43 through which the bar stock can pass. The end of the guide sleeve 43 away from the support plate 28 has a slot 44 for the saw blade 11 to reciprocate and cut the bar stock. The end of the guide sleeve 43 has an open slot 45 that allows the cut bar stock to fall. The guide sleeve 43 guides the bar stock, keeping it in a relatively stable state, which is beneficial for improving cutting quality. The slot 44 allows the saw blade 11 to extend through it, ensuring that the bar stock on both sides of the saw blade 11 is constrained by the guide sleeve. This prevents the saw blade 11 from applying bending moment force to the bar stock during cutting, which could cause the bar stock to bend and the cut end face to tilt, thus improving cutting quality.

[0039] The mounting bracket 1 has a slot 46 for the cut blank to fall through. A funnel 47 for collecting coolant and the cut blank is connected to the upper end of the slot 46, and a rectangular tube 48 is connected to the lower end of the slot 46. The funnel 47 can collect coolant, the cut semi-finished bar stock, and debris as they flow from the slot 46 into the rectangular tube 48, which facilitates the collection of parts and prevents coolant and debris from splashing everywhere.

[0040] The fixed frame 1 is connected to an oil tank 49 for lubricating the cylindrical cam 17. Since the guide post 20 and the cylindrical cam 17 are in line contact, the contact pressure is high, which can easily cause wear and put a large load on the motor. By setting up lubrication, the lower half of the cylindrical cam 17 is immersed in lubricating oil, which can reduce the wear of the cylindrical cam 17 and make its operation smoother.

[0041] The water storage tank 40 is equipped with a filter plate 50 on its upper part. The filter plate 50 can screen out cutting debris and semi-finished bar stock, allowing the coolant to re-enter the water storage tank 40, thereby improving the reuse of cooling water and reducing operating costs.

[0042] A fixing rod 51 is connected and installed on the fixing frame 1, and the guide rail plate 3 is connected and installed to the fixing rod 51 through a tension spring 52. In order to improve efficiency and speed up the non-cutting stroke of the cutting mechanism 100, the surface curvature of the cylindrical cam 17 becomes steeper, which will cause the guide rail plate 3 to return quickly with the cutting mechanism 100. However, the groove of the cylindrical cam 17 will bear a lot of pressure, accelerating wear. By setting the tension spring 52 to pull the guide rail plate 3, the wear of the cylindrical cam 17 can be reduced, the cutting efficiency can be improved, and the service life of the device can be extended.

[0043] It should be noted that the contact surfaces of the guide rail plate 3 and guide rail groove 2, the contact surfaces of the guide groove 202 and guide post 201, and the gear set, etc., which slide relative to each other, require regular maintenance and lubrication. The coolant also needs to be replaced regularly. The motor has a large power, so short circuit and overload protection should be implemented. A contactor should be used for switching to avoid indirect or direct contact with high voltage. An emergency stop switch should be provided and placed in a conspicuous location. Before use, operators should be given safety training according to the instruction manual to ensure safety. The power should be disconnected before operation during maintenance. When special operations are required, a special operation certificate is required to carry out maintenance and installation.

[0044] In operation, the cutting mechanism 100, feeding mechanism 200, motor 12, and water pump 41 are activated. The feeding mechanism 200 continuously feeds bar stock to the cutting mechanism 100. The rotating saw blade 11, cooled by the coolant, cuts the bar stock. After cutting, the discarded blank, along with the coolant and debris, falls from the slot 46 along the rectangular tube 48. The coolant re-enters the water tank 40, the cutting mechanism 100 retracts, and the feeding mechanism 200 continues to feed the bar stock forward. The cutting mechanism 100 then cuts the bar stock again. After the bar stock is almost completely cut, the operator needs to add more bar stock for continuous cutting. This device can continuously perform material feeding operations, improving production efficiency, reducing labor intensity, improving product consistency, and reducing operating costs. It can also be further automated by using a loading mechanism, allowing the bar stock placement to be completed through the loading mechanism, further reducing labor costs.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
