Description

Technical Field

[0001] This utility model relates to the technical field of quartz ring processing equipment, and in particular to a precision cutting and positioning device for quartz rings. Background Technology

[0002] Cutting is a crucial step in the processing of quartz rings, as its precision directly affects the subsequent performance and quality of the quartz rings. Currently, common quartz ring cutting devices on the market have many shortcomings in positioning. Traditional positioning methods often rely on manual adjustment, which is not only cumbersome and time-consuming, but also has low positioning accuracy, making it prone to cutting deviations and resulting in a high scrap rate for quartz ring products.

[0003] For example, Chinese patent CN202023330138.8 discloses a quartz ring cutting device. A set of symmetrically arranged locking telescopic devices are arranged around the periphery of a horizontal base plate. The telescopic shaft of the locking telescopic device is connected to a locking base block. A cutting power device is arranged above the horizontal base plate. The lower end of the output shaft of the cutting power device is connected to a cutting frame. Several evenly distributed orthogonal horizontal strips are arranged on the cutting frame. Several equally spaced blade mounting slots for mounting cutting blades are opened on each orthogonal horizontal strip. Several reinforcing support strips corresponding to the positions of the blade mounting slots are obliquely connected between adjacent orthogonal horizontal strips.

[0004] The aforementioned cutting device reduces manual intervention to some extent by clamping and positioning the quartz ring in different positions. However, the positioning operation is cumbersome and there is still a problem of unstable positioning. During the cutting process, due to the brittle nature of the quartz ring and the vibration generated during cutting, the existing positioning structure is difficult to fix the quartz ring firmly and accurately, which can easily cause the quartz ring to shift during the cutting process, thereby affecting the cutting accuracy. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, and to propose a precision cutting and positioning device for quartz rings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision cutting and positioning device for quartz rings, comprising a controller and a rotating mechanism. A positioning mechanism is installed on the top of the rotating mechanism. The positioning mechanism includes a disc, with multiple scale plates fixed in a circular array on the top of the disc. Multiple sliding grooves are formed in the circular array on the top of the disc. A clamping cylinder is fixedly installed at one end of the sliding groove near the outer edge of the disc. A drive rod facing the center of the disc is fixed at one end of the clamping cylinder. A clamping plate is fixedly installed at the end of the drive rod facing the center of the disc. The bottom end of the clamping plate is slidably installed with the sliding groove. Buffer pads are adhered to both sides of the clamping plate. Extension plates are fixedly connected to the other two sides of the clamping plate. A pressure sensor is installed between the clamping plate and the buffer pads. Rubber pads are adhered to both sides of the extension plates.

[0007] Preferably, the end of the extension plate away from the clamping plate is bent toward the center of the disk, and the number of scale plates and slide grooves is the same.

[0008] Preferably, shock-absorbing pads are adhered to both sides of the scale plate.

[0009] Preferably, the rotating mechanism includes a base, a support plate, a rotary motor, a drive gear, and a driven gear. The support plate is fixedly installed on the top of the base, and the rotary motor is fixedly installed on one side of the support plate.

[0010] Preferably, the output end of the rotary motor is fixedly connected to the bottom of the drive gear, and the outer edge of the drive gear meshes with the outer edge of the driven gear.

[0011] Preferably, the driven gear is rotatably mounted on the top of the support plate, and the top of the driven gear is welded to the bottom of the disk.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the positioning mechanism uses four clamping cylinders to drive multiple clamping plates and extension plates to move, clamping the quartz ring from all sides. The clamping force is uniform, which can firmly fix the quartz ring and prevent it from shifting during the cutting process. The buffer pads on the side walls of the clamping plates and the rubber pads on the side walls of the extension plates are made of elastic rubber, which can not only increase the friction between the clamping plates and the quartz ring, but also provide buffer protection for the quartz ring during the clamping process, avoiding damage to the quartz ring due to excessive clamping force. At the same time, by adjusting the movement of the clamping plates, it can adapt to the positioning requirements of quartz rings of different sizes. The clamping force of the clamping plates can be detected in real time by the pressure sensor, and the detection data can be fed back to the controller. The controller automatically adjusts the working state of the clamping cylinders according to the feedback data, realizing automated positioning and clamping, reducing manual intervention, improving production efficiency, and being easy to operate. 2. In this utility model, by placing the quartz ring on multiple scale plates and shock-absorbing pads, the shock-absorbing pads are made of polyurethane material, which can effectively absorb the vibration generated by the device during the cutting process, avoid the vibration from affecting the positioning and cutting accuracy of the quartz ring, and further improve the product quality.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-4As shown, this utility model provides a precision cutting and positioning device for quartz rings, including a controller 1 and a rotating mechanism 2. A positioning mechanism 3 is mounted on the top of the rotating mechanism 2. The positioning mechanism 3 includes a disc 31. Multiple scale plates 36 are fixed in a circular array on the top of the disc 31, and multiple sliding grooves 32 are formed in the circular array on the top of the disc 31. A clamping cylinder 33 is fixedly mounted at one end of the sliding groove 32 near the outer edge of the disc 31, and a drive rod 34 is fixed at one end of the clamping cylinder 33 toward the center of the disc 31. A clamping plate 35 is fixedly installed at the end of the disc 31. The bottom end of the clamping plate 35 is slidably installed with the slide groove 32. Buffer pads 310 are glued to both sides of the clamping plate 35. Extension plates 38 are fixedly connected to the other two sides of the clamping plate 35. A pressure sensor 311 is installed between the clamping plate 35 and the buffer pads 310. Rubber pads 39 are glued to both sides of the extension plate 38. The end of the extension plate 38 away from the clamping plate 35 is bent towards the center of the disc 31. The number of scale plates 36 is the same as the number of slide grooves 32. Shock-absorbing pads 37 are glued to both sides of the scale plates 36.

[0018] The specific settings and functions of this embodiment are described below: Before cutting the quartz ring, the device first places the quartz ring on the disk 31. The disk 31 has multiple scale plates 36 arranged in a circular array. The scale lines on the scale plates 36 make it easy for the staff to place the quartz ring in the middle of the disk 31 so that the center of the disk 31 is aligned with the center of the quartz ring. The controller 1 activates multiple clamping cylinders 33 of the positioning mechanism 3. The drive rod 34 of the clamping cylinder 33 pushes the clamping plate 35 towards the quartz ring. The buffer pad 310 on the side wall of the clamping plate 35 contacts and clamps the outer wall of the quartz ring. The pressure sensor 311 detects the clamping force of the clamping plate 35 on the quartz ring in real time and feeds the detection data back to the controller 1. When the clamping force reaches a preset value, the controller 1 controls the clamping cylinders 33 to stop working. At this time, the clamping plate 35 contacts the quartz ring through the buffer pad 310 on its side wall, and the extension plates 38 on both sides of the clamping plate 35 contact the quartz ring through the rubber pads 39 on their side walls. This allows for precise calibration of the quartz ring's position, ensuring it is in the correct cutting position, effectively improving positioning accuracy, reducing cutting deviation, and allowing subsequent cutting operations (such as...) to proceed. Figure 3 As shown, when it is necessary to cut the outer wall of the quartz ring, multiple clamping plates 35 can be used to tighten the inner wall of the quartz ring outwards; when it is necessary to cut the inner wall of the quartz ring, multiple clamping plates 35 can be used to clamp the outer wall of the quartz ring. The positioning mechanism 3 uses four clamping cylinders 33 to clamp the quartz ring from all sides. The clamping force is uniform and can firmly fix the quartz ring, preventing it from shifting during the cutting process. The buffer pads 310 on the side wall of the clamping plate 35 and the rubber pads 39 on the side wall of the extension plate 38 are made of elastic rubber, which not only increases the friction between the clamping plate and the quartz ring, but also provides a buffer protection for the quartz ring during the clamping process, preventing damage to the quartz ring due to excessive clamping force. At the same time, the clamping plate 35 can be moved by adjustment to adapt to the positioning requirements of quartz rings of different sizes. The pressure sensor 311 can detect the clamping force of the clamping plate 35 in real time and feed the detection data back to the controller 1. The controller 1 automatically adjusts the working state of the clamping cylinders 33 according to the feedback data to achieve automated positioning and clamping, reduce manual intervention, improve production efficiency, and is easy to operate. The quartz ring is placed on multiple scale plates 36 and shock-absorbing pads 37. The shock-absorbing pads 37 are made of polyurethane material, which can effectively absorb the vibration generated by the device during the cutting process, avoid the vibration from affecting the positioning and cutting accuracy of the quartz ring, and further improve the product quality.

[0019] Example 2: Figure 1 and Figure 2 As shown, the rotating mechanism 2 includes a base 21, a support plate 22, a rotary motor 23, a drive gear 24, and a driven gear 25. The support plate 22 is fixedly installed on the top of the base 21, the rotary motor 23 is fixedly installed on one side of the support plate 22, the output end of the rotary motor 23 is fixedly connected to the bottom of the drive gear 24, the outer edge of the drive gear 24 meshes with the outer edge of the driven gear 25, the driven gear 25 is rotatably installed on the top of the support plate 22, and the top of the driven gear 25 is welded to the bottom of the disc 31.

[0020] The overall effect of this embodiment is that by adding a rotating mechanism 2, the driving gear 24 is driven to rotate by a rotating motor 23, thereby driving the driven gear 25 and the positioning mechanism 3 to rotate as a whole, which facilitates the adjustment of the cutting angle of the quartz ring during the cutting process.

[0021] The device is used and operates as follows: Before cutting the quartz ring, the quartz ring is placed on the disc 31, and the center of the disc 31 is aligned with the center of the quartz ring. The controller 1 activates multiple clamping cylinders 33 of the positioning mechanism 3. The drive rod 34 of the clamping cylinder 33 pushes the clamping plate 35 to move towards the quartz ring. The pressure sensor 311 detects the clamping force of the clamping plate 35 on the quartz ring in real time and feeds the detection data back to the controller 1. When the clamping force reaches the preset value, the controller 1 controls the clamping cylinder 33 to stop working. At this time, the clamping plate 35 contacts the quartz ring through the buffer pad 310 on its side wall, and the extension plates 38 on both sides of the clamping plate 35 contact the quartz ring through the rubber pads 39 on its side wall. The position of the quartz ring can be accurately calibrated to ensure that the quartz ring is in the correct cutting position. The positioning mechanism 3 uses four clamping cylinders 33 to clamp the quartz ring from all sides, which can firmly fix the quartz ring. The buffer pads 310 on the side wall of the clamping plate 35 and the rubber pads 39 on the side wall of the extension plate 38 are made of elastic rubber, which can not only increase the friction between the clamping plate and the quartz ring, but also provide buffer protection for the quartz ring during the clamping process, so as to avoid damage to the quartz ring due to excessive clamping force. At the same time, by adjusting the movement of the clamping plate 35, it can adapt to the positioning requirements of quartz rings of different sizes. The pressure sensor 311 can detect the clamping force of the clamping plate 35 in real time and feed the detection data back to the controller 1. The controller 1 automatically adjusts the working state of the clamping cylinders 33 according to the feedback data to achieve automated positioning and clamping.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
