Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical processing equipment technology, specifically a tail shank processing device. 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 the core component of the temperature control system, the thermostat's tail is made from brass rods through multiple precision processes. In the initial blanking process, the brass rods are cut into brass column blanks of a specific length, and then one end of the blank needs to be drilled and chamfered in sequence.
[0004] However, existing processing equipment is limited by a single-process operation mode. After each process is completed, the brass column blank must be re-clamped and positioned before the next process can begin. This processing method not only makes the production process cumbersome and lengthy, significantly reducing processing efficiency, but also the frequent re-clamping can easily introduce positioning errors, resulting in a decrease in product processing accuracy. This, in turn, affects the overall yield of the thermostat tailstock, posing a dual challenge to both efficiency and quality in manufacturing. Utility Model Content
[0005] To address the problems of cumbersome production processes, low processing efficiency, and low processing precision in existing tailstock processing devices, this utility model provides a tailstock processing device.
[0006] This utility model is achieved through the following technical solution: A tailstock machining device includes a worktable, an electric spindle connected to the worktable, a chuck for clamping tailstock blanks connected to the output end of the electric spindle, a sliding seat fixedly mounted on the worktable, a first sliding plate adjustable along the axis of the chuck on the upper side of the sliding seat, a second sliding plate adjustable along the axis perpendicular to the chuck on the upper side of the first sliding plate, two sets of cutting tools connected to the side of the second sliding plate near the chuck, a rotating shaft rotatably connected to the side wall of the worktable via a bearing seat, a geared motor for driving the rotating shaft to rotate connected to the worktable, a first cam connected to one end of the rotating shaft, a guide post slidingly engaged with the first cam connected to the side wall of the first sliding plate, and a spring exerting a pulling force on the first sliding plate away from the electric spindle connected to the worktable.
[0007] A further improvement of this utility model is that a cylinder is connected and installed on the side wall of the second slide, and the end of the telescopic rod of the cylinder is connected and installed to the side of the first slide.
[0008] A further improvement of this utility model is that a second cam is connected and installed on the rotating shaft, and a first reversing valve for controlling the extension and retraction of the cylinder is connected and installed on the side wall of the worktable, and the reversing handle of the first reversing valve slides in the groove of the second cam.
[0009] A further improvement of this utility model is that the chuck is a pneumatic chuck, a third cam is connected and installed on the rotating shaft, and a second reversing valve for controlling the opening and closing of the pneumatic chuck is connected and installed on the side wall of the worktable. The reversing handle of the second reversing valve slides in the groove of the third cam.
[0010] A further improvement of this utility model is that a rotating seat is connected and installed on the worktable, a fourth cam is connected and installed on the rotating shaft, a rotating plate is rotatably connected to the rotating seat, a grooved cylinder for storing bar stock is connected and installed at one end of the rotating plate, and a sliding rod that slides in cooperation with the fourth cam is connected and installed at the other end, a disc is connected and installed on the rotating shaft, an arc-shaped block is connected and installed on the side of the disc, a push rod that slides at one end in the groove of the cylinder and slides in cooperation with the arc-shaped block at the other end is rotatably connected and installed on the rotating plate, a compression spring is connected and installed between the push rod and the rotating plate, an auxiliary rod is connected and installed on the worktable, and a tension spring is connected and installed between the auxiliary rod and the rotating plate.
[0011] A further improvement of this utility model is that a vertical rod is connected and installed on the electric spindle, a dropper bottle is connected and installed on the vertical rod, and a dropper tube is connected and installed below the dropper bottle to drip coolant onto the tool machining area.
[0012] A further improvement of this invention is that an oil tank for lubricating the first cam is connected and installed on the side wall of the worktable.
[0013] As can be seen from the above technical solutions, the beneficial effects of this utility model are: In operation, the bar stock is placed in the chuck for clamping and fixing. The electric spindle and geared motor are started, and the geared motor drives the rotating shaft to rotate. The rotating shaft drives the first cam to rotate, and the first cam, through the guide post, moves the first sliding plate closer to the workpiece. This, in turn, moves the cutting tool closer to the workpiece for machining. After the hole is machined, the first sliding plate retracts under the action of the first cam and the spring, reversing the direction of the cylinder, causing the cylinder to extend and drive the second sliding plate to move back and forth, aligning the other set of cutting tools with the workpiece. The first cam continues to drive the first sliding plate to feed towards the workpiece, completing the chamfering process. This device uses a cylinder to drive two sets of cutting tools to machine the workpiece separately, achieving the effect of completing two processes in one clamping, greatly improving work efficiency and workpiece machining accuracy.

[0020] 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.
[0021] like Figure 1-4As shown, a tailstock machining device includes a worktable 1, on which an electric spindle 2 is connected and installed (with the axis of the electric spindle 2 as the left-right direction and the direction perpendicular to the axis as the front-back direction). A self-centering chuck 3 capable of clamping a tailstock blank is connected and installed at the output end of the electric spindle 2. A sliding seat 4 with a dovetail guide rail is fixedly installed on the worktable 1. A first sliding plate 5, which can slide and adjust along the axis of the chuck 3 and is nested with the dovetail guide rail, is installed on the upper side of the sliding seat 4. A second sliding plate 6, which can slide and adjust along the direction perpendicular to the axis of the chuck 3, is installed on the upper side of the first sliding plate 5. Two sets of tools 61 parallel to the axis of the electric spindle 2 are connected and installed on the side of the second sliding plate 6 near the chuck 3 via a tool holder fixing plate. One set is a drill bit for drilling, and the other is a chamfering tool for chamfering. A cylinder 7 is connected and installed on the side wall of plate 6 via a cylinder mounting bracket. The end of the telescopic rod 8 of cylinder 7 is connected and installed to the side of the first slide plate 5. Bolts with stops are connected and installed on the front and rear side walls of the first slide plate 5 to limit the stroke of cylinder 7. The stops at the ends of the bolts can limit the movement stroke of the second slide plate 6. A bearing seat 9 is connected and installed on the side wall of worktable 1. A rotating shaft 10 is rotatably connected and installed in the bearing seat 9 via a bearing. A geared motor 11 that drives the rotating shaft 10 to rotate is connected and installed on the side wall of worktable 1. The geared motor 11 consists of a motor and a gearbox. A first cam 12 is connected and installed at one end of the rotating shaft 10. A guide post 13 that slides and engages with the first cam 12 is connected and installed on the side wall of the first slide plate 5. A spring 14 that pulls the first slide plate 5 away from the electric spindle 2 is connected and installed on worktable 1.
[0022] In use, the bar stock is placed in the chuck 3 for clamping and fixing. The jaws of the chuck 3 are self-centering, allowing the workpiece to be processed to rotate coaxially with the electric spindle 2. The electric spindle 2 and the geared motor 11 are started. The geared motor 11 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the first cam 12 to rotate. The first cam 12 drives the first slide plate 5 to feed towards the workpiece through the guide post 13, and then drives the tool 61 to approach the workpiece for processing. First, the drill bit on one side is used to process the required hole. After the hole is processed, the first slide plate 5 is retracted under the action of the first cam 12 and the spring 14, and then the tool 61 is retracted. Then, the cylinder 7 is started to reverse, so that the cylinder 7 extends the telescopic rod 8, which drives the second slide plate 6 to move back and forth. The stop block can constrain the movement of the cylinder 7 to the designated position, so that the other set of tools 61 is aligned with the workpiece. The first cam 12 continues to drive the first slide plate 5 to feed towards the workpiece, completing the chamfering process. This device uses cylinder 7 to drive two sets of cutting tools 61 to process the workpiece, achieving the effect of completing two processes in one clamping, which improves the efficiency and accuracy of workpiece processing and reduces production costs.
[0023] It should be noted that the front and rear positions of the cutting tool 61 are respectively the positions when the telescopic rod 8 inside the cylinder 7 is fully extended and fully retracted. When setting the tool, the cylinder 7 needs to be placed in the fully extended or fully retracted state first, the cutting tool 61 is installed on the tool holder and fixed, and then the cutting tool 61 on the other side is set and fixed in the same way.
[0024] A cylinder 7 is connected and installed on the side wall of the second slide plate 6 via a cylinder mounting bracket. The end of the telescopic rod 8 of the cylinder 7 is connected and installed to the side of the first slide plate 5. The rotating shaft 10 is connected to and installed with a second cam 15, and the worktable 1 has a first reversing valve 16 connected to and installed on its side wall to control the extension and retraction of the cylinder 7. The reversing handle of the first reversing valve 16 slides in the groove of the second cam 15. When the first cam 12 rotates to the point where the tool 61 is completely withdrawn from machining, the second cam 15 rotates and drives the reversing handle of the first reversing valve 16 to slide to the other side. The first reversing valve 16 changes the direction of gas flow, causing the cylinder 7 to retract or extend, so that another tool 61 is aligned with the workpiece to be machined. Under the rotation of the first cam 12, the tool continues to complete another machining operation. Moreover, when all operations are completed, the first cam 12 drives the first slide plate 5 to retract a large distance, leaving space for re-clamping the workpiece. At the same time, the rotation of the second cam 15 drives the reversing handle of the first reversing valve 16 to slide to the other side, causing the cylinder 7 to move and switch to another tool 61 to continue machining. This allows for automatic tool changing after the first operation is completed, enabling the second operation to be performed, thus improving machining efficiency.
[0025] The chuck 3 is a pneumatic chuck. A third cam 17 is connected and installed on the rotating shaft 10. A second reversing valve 18, which controls the opening and closing of the pneumatic chuck 3, is connected and installed on the side wall of the worktable 1. The reversing handle of the second reversing valve 18 slides within the groove of the third cam 17. After the tool 61 has completely finished machining the workpiece and retracted, the third cam 17 rotates, causing the reversing handle of the second reversing valve 18 to slide to the other side, causing the pneumatic chuck to release the workpiece. The workpiece falls naturally under gravity and is then placed back into the workpiece to be machined. When the tool 61 begins to move towards the workpiece, the third cam 17 rotates, causing the reversing handle of the second reversing valve 18 to slide to the other side, causing the pneumatic chuck to re-clamp the workpiece. The tool 61 continues to machine the workpiece. This system can automatically clamp the workpiece, with fast clamping speed and stable clamping force, improving production efficiency and product quality.
[0026] It should be noted that all pneumatic components are connected to the air pump via air pipes, ensuring stable air pressure output and providing sufficient pressure for the relevant pneumatic components.
[0027] The workbench 1 is equipped with a rotating seat 19, a fourth cam 20 is equipped with a rotating shaft 10, a rotating plate 21 is rotatably connected to the rotating seat 19, a grooved cylinder 22 for storing bar stock is connected to one end of the rotating plate 21, and a slide rod 23 that slides with the fourth cam 20 is connected to the other end of the rotating plate 21. A disc 24 is connected to the rotating shaft 10, and an arc block 25 is connected to the side of the disc 24. A push rod 26 is rotatably connected to the rotating plate 21, with one end sliding in the groove of the cylinder 22 and the other end sliding with the arc block 25. A compression spring 27 is connected between the push rod 26 and the rotating plate 21. An auxiliary rod 28 is connected to the workbench 1, and a tension spring 29 is connected between the auxiliary rod 28 and the rotating plate 21. The vibratory feeder arranges the material in a row and enters the cylinder 22 of the rotating plate 21. The fourth cam 20 rotates, causing the rotating plate 21 to rotate around the rotating seat 19, bringing the workpiece to be processed to the inlet of the pneumatic chuck. The outer diameter of the fourth cam 20 remains unchanged, allowing the rotating plate 21 to stay here for a period of time. The disc 24 drives the arc block 25 to rotate, which in turn drives the push rod 26 to swing. At the same time, the push rod 26 slides in the groove of the cylinder 22, pushing the workpiece to be processed into the inlet of the pneumatic chuck. The pneumatic chuck clamps the workpiece for the next step of processing, realizing automatic feeding, improving the level of automation in production, ensuring product consistency, improving production efficiency, and reducing the labor intensity and production cost of manual feeding.
[0028] It should be noted that an automated feeding mechanism is required to allow the material to be processed to slide into the cylinder 22 for easy movement onto the clamping plate 3. The rotating plate 21 is equipped with a fan-shaped baffle that can block the discharge port of the feeding mechanism. After the rotating plate 21 returns, the material is re-clamped into the cylinder 22.
[0029] The electric spindle 2 is equipped with a support rod 30, and a drip bottle 31 is connected to the support rod 30. Below the drip bottle 31, a drip tube 32 is connected to the dripping tube, which drips coolant onto the machining area of the tool 61. This provides cooling for the tool 61, preventing it from overheating and affecting the cutting quality, thus improving product quality. It also ensures that the tool 61 can work continuously, reducing the frequency of downtime for maintenance and tool replacement, and improving production efficiency.
[0030] An oil tank 33 for lubricating the first cam 12 is connected and installed on the side wall of the worktable 1. This provides lubrication to the first cam 12, preventing wear caused by sliding friction and affecting production accuracy.
[0031] It should be noted that since the forces on other cams are relatively small, they only need to be lubricated daily and do not need to be soaked in oil. For relatively sliding parts, regular lubrication is required as needed to prevent dry friction from causing wear and affecting the accuracy of the fit.
[0032] In use, the electric spindle 2 and the geared motor 11 are started. The electric spindle 2 drives the chuck 3 to rotate. At this time, the pneumatic chuck is in the open state. The geared motor 11 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the fourth cam 20 to rotate. Under the action of the tension spring 29, the rotating plate 21 rotates around the rotating seat 19, sending the material in the cylinder 22 to the chuck 3. The rotating plate 21 remains stationary for a period of time. The disc 24 drives the arc block 25 to rotate. When it touches the push rod 26, it causes the push rod 26 to swing, pushing the material in the cylinder 22 into the chuck 3. The third cam 17 rotates, driving the reversing handle of the second reversing valve 18 to reverse, so that the pneumatic chuck clamps the material. Then the rotating plate 21 retracts. When the first cam 12 rotates, the first slide plate 5 slides to the right via the guide post 13, bringing the tool 61 close to the material for the first machining operation. After the first machining operation is completed, the first cam 12 retracts to create space for tool changing. The second cam 15 drives the reversing handle of the first reversing valve 16 to change direction, causing the cylinder 7 to drive the telescopic rod 8 to push the second slide plate 6 to move back and forth, switching to another tool 61. Then the first slide plate 5 continues to feed to the right to complete the other machining operation. In this way, two machining operations on the workpiece are achieved with one workpiece clamping, which greatly improves production efficiency, reduces manual labor intensity, improves the precision of production and processing, and reduces errors.
