Abstract

This utility model discloses a bead chamfering machine, belonging to the technical field of bead processing equipment. It includes a frame, with a feeding pipe running through the top plate of the frame. A clamping mechanism fixed to the frame is located on one side of the feeding pipe, and a drive mechanism fixed to the frame is located on the other side. A chamfering mechanism and a distance measuring mechanism are mounted on the drive mechanism. By designing a chamfering machine composed of a drive mechanism, a distance measuring mechanism, a clamping mechanism, and a controller, a high-precision distance measuring sensor is used to accurately measure the distance of the bead material in the three-jaw chuck, achieving micron-level distance measurement of the cutting residue at both ends.

This achieves high-precision processing, reduces tool setting operations, and improves processing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of bead processing equipment technology, and in particular to a bead beveling machine. Background Technology

[0002] The process of making collectible beads involves turning the raw material into a cylinder or cube, then performing a fine drilling process, and finally, through rough and fine grinding, the bead gradually takes on a perfect round shape and becomes a bead.

[0003] During bead processing, cutting allowances are left on both sides. Traditional cutting machines rely on manual clamping of the material. Due to the lack of high-precision distance sensors and the unevenness of manual loading, the cutting machine's cutting of the allowances is inaccurate, resulting in residual parts. This increases the need for secondary grinding, or excessive cutting may cause beads to be scrapped. Furthermore, because the size of the cutting allowances varies, the cutting machine cannot adaptively adjust its tool setting for the same batch of beads, thus reducing production efficiency.

[0004] To address the above problems, a bead chamfering machine is proposed. Utility Model Content

[0005] The main purpose of this invention is to provide a bead chamfering machine that solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A bead chamfering machine includes a frame, a feeding pipe is provided through the top plate of the frame, a clamping mechanism is provided on one side of the feeding pipe and fixed on the frame, and a driving mechanism is provided on the other side of the feeding pipe and fixed on the frame. A chamfering mechanism and a distance measuring mechanism are installed on the driving mechanism.

[0008] The drive mechanism includes a lead screw guide rail that is bolted to the top plate of the frame. The lead screw guide rail is divided into an X-axis lead screw guide rail and a Y-axis lead screw guide rail. The X-axis lead screw guide rail and the Y-axis lead screw guide rail are slidably connected. A stepper motor is installed on one end of both the X-axis lead screw guide rail and the Y-axis lead screw guide rail.

[0009] The chamfering mechanism includes a tool moving seat that is slidably connected to the lead screw guide rail, and a cutting tool is detachably clamped in the groove on the outer wall of the tool moving seat;

[0010] The ranging mechanism includes a sliding sleeve seat that is mounted on the outer wall of the tool moving seat by screws. A high-precision ranging sensor is fixed on one side of the sliding sleeve seat, and a ranging probe is slidably arranged on the other side of the sliding sleeve seat.

[0011] Furthermore, the clamping mechanism includes a transmission box fixedly installed on the top of the frame, a clamping arm rotatably installed on the output end of the outer side of the transmission box, a three-jaw chuck that can be opened and closed is provided on one end of the outer side of the clamping arm, and a rotary motor is rotatably connected to the other side of the transmission box via a belt.

[0012] Furthermore, a waste suction tube is provided through the interior of the tool moving seat, and the position of the waste suction tube is fixed relative to the cutting tool.

[0013] Furthermore, a telescopic probe is elastically mounted on the measuring end of the high-precision ranging sensor, and the telescopic probe is aligned with the ranging probe rod.

[0014] Furthermore, a loading probe is fitted onto the end of the ranging probe away from the telescopic probe. A loading needle is formed on the loading probe, and a bead raw material body is threaded onto the loading needle.

[0015] Furthermore, a control box is fixed on the back support leg of the frame, and a controller is connected to the top of the control box via a wire.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This invention designs a chamfering machine consisting of a drive mechanism, a ranging mechanism, a clamping mechanism, and a controller. The high-precision ranging sensor in the ranging mechanism precisely measures the distance between the raw bead material and the three-jaw chuck, achieving micron-level distance measurement of the cutting residue at both ends. After processing by the controller, the X and Y axis stepper motors and lead screw guides of the drive mechanism control the tool moving seat and the cutting tool to precisely cut the cutting residue, avoiding excess material or scrapping of the beads. This achieves high-precision machining while also adaptively adjusting the initial position of the cutting tool, reducing tool setting operations and improving processing efficiency.

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-5 As shown, this embodiment provides a bead chamfering machine, including a frame 1. A feeding pipe 8 is provided through the top plate of the frame 1. A clamping mechanism 2 fixed to the frame 1 is provided on one side of the feeding pipe 8, and a driving mechanism 4 fixed to the frame 1 is provided on the other side of the feeding pipe 8. A chamfering mechanism 3 and a distance measuring mechanism 6 are installed on the driving mechanism 4. The driving mechanism 4 includes a lead screw guide rail 402 bolted to the top plate of the frame 1. The lead screw guide rail 402 is divided into an X-axis lead screw guide rail and a Y-axis lead screw guide rail. The X-axis lead screw guide rail and the Y-axis lead screw guide rail are connected. The X-axis lead screw guide and the Y-axis lead screw guide are both fitted with stepper motors 401 at their outer ends; the chamfering mechanism 3 includes a tool moving seat 301 that is slidably connected to the lead screw guide 402, and a cutting tool 301a is detachably clamped in the groove on the outer wall of the tool moving seat 301; the ranging mechanism 6 includes a sliding sleeve seat 603 that is installed on the outer wall of the tool moving seat 301 by screws, a high-precision ranging sensor 604 is fixed on one side of the sliding sleeve seat 603, and a ranging probe 602 is slidably arranged on the other side of the sliding sleeve seat 603.

[0027] In the above structure, the feed tube 8 falls and is collected after the bead cutting process is completed; the high-precision distance sensor 604 has a built-in micron-level distance sensor. The sensor measures the position change of the object by constructing a laser triangle geometric relationship. Its basic principle is to use the reflected light formed after the laser beam is projected onto the surface of the object, and to calculate the position change of the object by measuring the offset of the light on the sensor.

[0028] The clamping mechanism 2 includes a transmission box 201 fixedly installed on the top of the frame 1. A clamping arm 203 is rotatably installed on the output end of the outer side of the transmission box 201. A three-jaw chuck that can be opened and closed is provided at one end of the outer side of the clamping arm 203. A rotary motor 202 is rotatably connected to the other side of the transmission box 201 via a belt. The three-jaw chuck is opened and closed by a built-in cylinder. The clamping arm 203 is driven to rotate at high speed by the rotary motor 202 and the belt and pulley mechanism.

[0029] A waste suction pipe 7 is installed inside the tool moving seat 301. The waste suction pipe 7 is fixed relative to the cutting tool 301a. The waste suction pipe 7 is connected to a negative pressure suction device to collect the waste.

[0030] A telescopic probe 604a is elastically mounted on the measuring end of the high-precision ranging sensor 604. The telescopic probe 604a is aligned with the ranging probe rod 602. The telescopic probe 604a is compressed after being pushed by the ranging probe rod 602. The telescopic probe 604a has a hollow structure. The ranging laser beam inside the sensor passes through the telescopic probe 604a and is reflected back to the receiver by the outer wall of the ranging probe rod 602.

[0031] A loading probe 601 is fitted onto the end of the ranging probe 602 away from the telescopic probe 604a. A loading needle is formed on the loading probe 601, and a bead raw material body 601a is threaded onto the loading needle. A return spring fitted on the ranging probe 602 is clamped between the loading probe 601 and the sliding sleeve seat 603. The cutting method for cutting the raw material on the bead raw material body 601a is to cut off the waste material at one end, collect it in a unified manner, and then perform a second cutting on the waste material at the other end.

[0032] A control box is fixed to the back support leg of the frame 1. A controller 5 is connected to the top of the control box via wires. The control box contains a control circuit board that receives distance data from a high-precision distance sensor 604. Through processor algorithms, the initial position of the cutting tool 301a can be adjusted, ensuring the cutting edge remains precisely positioned on the bead, preventing damage to the bead's outer wall while maintaining cutting accuracy. Furthermore, arc cutting can be achieved by inputting machining data, expanding the equipment's processing range.

[0033] The working principle of this device is as follows:

[0034] This device requires an external power source during use.

[0035] The bead material body 601a is manually inserted into the probe of the loading probe 601. The controller 5 starts the stepper motor 401 to drive the lead screw guide 402 to rotate. The loading probe 601 moves along the Y-axis lead screw guide along with the tool moving seat 301, aligning the bead material body 601a with the three-jaw chuck at one end of the clamping arm 203. The loading probe 601 moves again along the X-axis lead screw guide, and the bead material body 601a is fed into the three-jaw chuck, so that the cutting residue on one side abuts against the inner wall of the three-jaw chuck. The three-jaw chuck grips the bead material body.

[0036] The loading probe 601 continues to push the ranging probe 602 to move in the opposite direction along the X-axis lead screw guide, slide along the inner wall of the sliding sleeve seat 603, and squeeze the telescopic probe 604a. The displacement of the telescopic probe 604a in the high-precision ranging sensor 604 is collected by the built-in laser ranging unit, which detects the distance between the cutting residue on the other side and the outer wall of the bead raw material body 601a. ​​The loading probe 601 retracts from the three-jaw chuck, and after the data is processed in the controller 5, the stepper motor 401 at one end of the X and Y axis lead screw guide is controlled to drive the tool moving seat 301 to move and adjust, accurately positioning the initial position of the cutting tool 301a. The tool moving seat 301 is controlled again to move the shoelace cutting tool 301a along the Y-axis, close to the bead raw material body 601a in the three-jaw chuck, remove the cutting residue, and reload the loading probe 601 with new bead raw material.

[0037] By adopting the above structure, the flexibility of inspecting the raw materials of the beads after clamping can be improved during the bead cutting process, thereby improving the positioning accuracy of the cutting tool. This avoids the need for frequent tool adjustments required by traditional manual clamping, thus improving the processing efficiency and facilitating high-precision and high-efficiency processing of beads to meet market demands.

[0038] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0039] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
