Description

Technical Field

[0001] This application relates to the field of collet processing equipment technology, and more specifically, to a collet grinding device. Background Technology

[0002] Collets, as important locking devices for holding cutting tools, are widely used in equipment such as drilling and milling machines and machining centers. The machining accuracy of the collet end face directly affects the stability of tool clamping and the machining quality. Therefore, the end face grinding of the collet is a key step in the collet manufacturing process.

[0003] Traditional collet end face grinding methods involve grinding a fixed collet end face using the side plane of a grinding wheel. In practical use, this collet grinding device has several problems: First, traditional collet grinding devices require operators to manually place each collet onto the grinding station, which is not only inefficient but also prone to operator fatigue and increases the risk of operational errors due to frequent handling. Furthermore, manual placement of collets makes it difficult to ensure they are always placed in the same position, inevitably introducing human error that affects the accuracy of subsequent grinding processes and thus the quality of the collet grinding. When clamping the collets, manual operation cannot guarantee consistently uniform clamping force, introducing human error as well. In addition, manual loading and unloading pose safety hazards, have low stability, and cannot meet the needs of automated production, resulting in low efficiency in collet grinding.

[0004] To solve the above problems, there is an urgent need for a collet grinding device with stable feeding and high machining accuracy, so as to improve machining efficiency and improve the quality of collet grinding. Utility Model Content

[0005] To address the aforementioned problems, the present invention provides a collet grinding device that solves the issues of poor feeding stability and low processing accuracy in existing collet grinding devices. The device includes a grinding mechanism; a feeding mechanism is provided on one side of the grinding mechanism, comprising a slide, a retractable first baffle assembly, and a second baffle assembly; the outlet end of the slide is inclined downwards, and the first and second baffle assemblies are positioned near the outlet end of the slide, cooperating with each other to form a channel for a single collet to pass through; a clamping mechanism for transporting the collets is provided between the feeding mechanism and the grinding mechanism.

[0006] Preferably, the first baffle assembly includes a first baffle and a first drive unit, with the output shaft of the first drive unit connected to the first baffle; the second baffle assembly includes a second baffle and a second drive unit, with the output shaft of the second drive unit connected to the second baffle; and the first drive unit and the second drive unit are connected to a control mechanism.

[0007] Preferably, the distance between the end of the first baffle near the slide and the end of the second baffle near the slide is set to the length of a single collet.

[0008] Preferably, the clamping mechanism includes a mounting base, a robotic arm for transporting the collet, and a pin assembly for clamping the collet. The robotic arm is disposed on the side of the mounting base, and the pin assembly is disposed on the bottom surface of the mounting base. A gripper is connected to the free end of the robotic arm.

[0009] Preferably, the mounting base is connected to a drive mechanism that moves the mounting base.

[0010] Preferably, the grinding mechanism includes a grinding wheel disposed near the clamping mechanism.

[0011] Preferably, the grinding wheel has a zigzag structure.

[0012] Preferably, the discharge end of the chute is provided with a limiting plate to prevent the collet from falling off.

[0013] The beneficial effects of this utility model are as follows: The first baffle assembly and the second baffle assembly cooperate with each other to form a channel for a single collet to pass through, ensuring that only one collet is loaded at a time. This guarantees that the collets slide down the channel one by one in an orderly manner to the discharge port, avoiding the processing chaos caused by multiple collets entering the processing area at the same time. This makes the entire loading process more efficient, shortens the time interval between each collet's storage position and its entry into the grinding process, and improves overall production efficiency. The clamping mechanism has a compact structure and can efficiently complete the transportation of collets between different workstations, shortening the transportation time. The accurate clamping of the collets by the ejector pin assembly ensures the positioning accuracy of the collets in grinding and other processing processes, reduces processing deviations caused by transportation errors, and improves the processing quality and consistency of the products.

[0024] The present application will now describe a collet grinding device provided in an embodiment.

[0025] Please see Figure 1This is a schematic diagram of the structure of the present invention. The collet grinding device includes a grinding mechanism; a feeding mechanism is provided on one side of the grinding mechanism, the feeding mechanism including a slide 1, a retractable first baffle assembly 2 and a second baffle assembly 3; the discharge end of the slide 1 is inclined downward. Specifically, the slide 1 is made of a smooth material and its width is slightly wider than the width of the collet 4; when the collet 4 is placed in the slide 1, under the action of gravity, the collet 4 can slide down the slide 1 naturally and smoothly, and the collet 4 remains stable during the sliding process without shaking, ensuring that the subsequent clamping mechanism can accurately grasp the collet 4. The first baffle assembly 2 and the second baffle assembly 3 are located near the discharge end of the slide 1, and the first baffle assembly 2 and the second baffle assembly 3 cooperate with each other to form a channel for a single collet 4 to pass through with the slide 1; a clamping mechanism for transporting the collet 4 is provided between the feeding mechanism and the grinding mechanism. Specifically, the collet 4 slides towards the discharge end of the slide 1 under its own gravity. When the collet 4 approaches the discharge end of the slide 1, the first baffle assembly 2 and the second baffle assembly 3 cooperate with each other through extension and retraction to ensure that only one collet 4 can pass through at a time. The clamping mechanism is activated to transport the single collet 4 that has passed through the channel to the grinding mechanism, and the grinding mechanism performs grinding processing on the collet 4.

[0026] Furthermore, the first baffle assembly 2 includes a first baffle and a first drive unit, with the output shaft of the first drive unit connected to the first baffle; the second baffle assembly 3 includes a second baffle and a second drive unit, with the output shaft of the second drive unit connected to the second baffle; a control mechanism is connected to the first drive unit and the second drive unit. In this embodiment, both the first drive unit and the second drive unit use a motor as a power source. Under the driving action of the motor output shaft, the first baffle and the second baffle move, thereby realizing the extension and retraction of the first baffle assembly 2 and the second baffle assembly 3.

[0027] Furthermore, the distance between the end of the first baffle near the slide 1 and the end of the second baffle near the slide 1 is set to the length of a single collet 4 to ensure that only one collet 4 is fed at a time, avoiding continuous feeding.

[0028] Specifically, when it is necessary to control the passage of the collet 4, the control mechanism controls the first drive unit, which drives the first baffle downward. Simultaneously, the second drive unit, under the control of the control mechanism, drives the second baffle upward. The two work together to form a channel through which a single collet 4 can pass, ensuring that the collets 4 slide down the slide 1 one by one in an orderly manner to the discharge port. This avoids processing chaos caused by multiple collets 4 entering the processing area simultaneously, making the entire feeding process more efficient and shortening the time interval between each collet 4's storage position and its entry into the grinding process, thus improving overall production efficiency. By controlling the first and second drive units, the control mechanism achieves automated feeding of the collets 4, accurately controlling the feeding rhythm of the collets 4, improving the automation level of the entire collet 4 grinding device, and reducing labor costs and labor intensity.

[0029] Please see Figures 1 to 5 Furthermore, the clamping mechanism includes a mounting base 5, a robotic arm 6 for transporting the collet 4, and an ejector assembly 7 for clamping the collet 4. The robotic arm 6 is located on the side of the mounting base 5, and the ejector assembly 7 is located on the bottom surface of the mounting base 5. A gripper 8 is connected to the free end of the robotic arm 6, enabling the gripper 8 to move vertically and horizontally. Specifically, when the collet 4 reaches the discharge port of the slide 1, the robotic arm 6 moves the gripper 8 downwards to the collet 4, where the gripper 8 closes and grasps the collet 4. The robotic arm 6 then moves the gripper 8 upwards and horizontally above the ejector assembly 7. Finally, the robotic arm 6 moves the gripper 8 downwards, placing the collet 4 onto the ejector assembly 7. The ejector assembly 7 accurately and firmly clamps the collet 4 for subsequent processing. After completing the task of transporting the collet 4 from the slide 1 to the ejector assembly 7, the gripper 8 returns to its initial position. The clamping mechanism has a compact structure and can efficiently transport the collet 4 between different workstations, shortening the transport time. The pin assembly 7 accurately clamps the collet 4, ensuring accurate positioning of the collet 4 during grinding and other machining processes. This reduces machining deviations caused by handling errors, ensures consistent clamping force, and improves product processing quality and consistency. The clamping force of the gripper 8 can be flexibly adjusted according to the material and size of the collet 4 to adapt to the processing requirements of different types of collets 4. In this embodiment, the robotic arm is hydraulically driven.

[0030] In one embodiment, a drive mechanism is connected to the mounting base 5 to move the mounting base 5. In this embodiment, the feeding mechanism is connected to the mounting base 5, and the feeding mechanism moves together with the mounting base 5 when the drive mechanism moves the mounting base 5. When the collet 4 is clamped by the ejector assembly 7, the drive mechanism drives the entire mounting base 5 to move towards the grinding mechanism until the collet 4 contacts the grinding mechanism and the grinding mechanism begins operation. The ejector assembly 7 provides stable clamping for the grinding mechanism. After the collet 4 has been ground, the drive mechanism drives the mounting base 5 back to its original position, the ejector assembly 7 releases, and the processed collet 4 falls into the collecting mechanism below. The ejector assembly 7 waits for the next collet 4 to be processed.

[0031] Furthermore, the grinding mechanism includes a grinding wheel positioned near the clamping mechanism.

[0032] In one embodiment, the grinding wheel has a polygonal structure. The grinding wheel is driven by a high-speed motor, and its rotation speed can be flexibly adjusted according to actual processing requirements. During the grinding process, the polygonal structure of the grinding wheel can grind multiple surfaces of the collet 4 in one pass, achieving one-time grinding and shaping of the collet 4, thus improving processing efficiency and accuracy.

[0033] Furthermore, the discharge end of the slide 1 is provided with a limiting plate 9 to prevent the collet 4 from falling off.

[0034] The working process of this utility model is as follows: The collet 4 to be processed is placed in the slide 1. At this time, the first and second baffles are in the closed state, preventing the collet 4 from sliding down. After the device is started, the control mechanism manipulates the first baffle to move downward and the second baffle to move upward. Under the action of gravity, the single collet 4 slides to the discharge end of the slide 1. The gripper 8 descends and grabs the collet 4, moves upward under the drive of the robotic arm 6, and then moves horizontally above the ejector assembly 7. Then it descends and accurately places the collet 4 on the ejector assembly 7. The ejector assembly 7 quickly clamps the collet 4, and the gripper 8 releases and returns to the initial position. Driven by the mounting base 5, the ejector assembly 7 moves the collet 4 close to the grinding wheel. The grinding wheel rotates at high speed to perform grinding operations on the collet 4 until the predetermined processing accuracy is achieved. After grinding is completed, the mounting base 5 returns to its original position, and at the same time, the ejector assembly 7 releases, and the collet 4 falls into the collection mechanism below. The gripper 8 returns to its original position, then the first baffle moves down, the second baffle moves up, and the next collet 4 rolls orderly to the discharge end of the slide 1, and so on.

[0035] In this invention, the first baffle assembly 2 and the second baffle assembly 3 cooperate with each other to form a channel for a single collet 4 to pass through with the slide rail 1. This ensures that only one collet 4 is loaded at a time, guaranteeing that the collets 4 slide down the slide rail 1 one by one in an orderly manner to the discharge port end. This avoids the processing chaos caused by multiple collets 4 entering the processing area at the same time, making the entire loading process more efficient and shortening the time interval between each collet 4 from its storage position to entering the grinding process, thereby improving overall production efficiency. The clamping mechanism has a compact structure and can efficiently complete the transportation of the collets 4 between different workstations, shortening the transportation time. The pin assembly 7 accurately clamps the collets 4, ensuring the positioning accuracy of the collets 4 in grinding and other processing processes, reducing processing deviations caused by transportation errors, ensuring consistent clamping force, and improving the processing quality and consistency of the product.
