Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe grinding technology, and more specifically to a pipe end grinding device. Background Technology
[0002] Decorative material pipes, often referred to as decorative pipes, are a type of pipe that combines practicality and aesthetics. They not only meet the practical needs of piping systems but also add beauty and personality to buildings, homes, or industrial products through their unique appearance and design.
[0003] In existing technologies, to ensure that pipes meet design requirements such as aesthetics, sealing, installation quality, and service life, it is usually necessary to grind the pipe ends. In practice, the operator typically holds the decorative material pipe and places its end on a rotating grinding disc to grind it flat. During the grinding process, the operator needs to judge whether to stop grinding based on the grinding progress. This operation has many problems. On the one hand, the operator experiences high fatigue and low work efficiency over long periods of time. On the other hand, the posture of holding the pipe affects the grinding angle of the pipe end relative to the grinding fixture. If the grinding angle is not appropriate, delamination, burrs, and tilting of the ground end may occur during the grinding process, greatly reducing the grinding accuracy. In addition, relying on the operator to judge when to stop grinding may lead to inconsistent grinding results, including over-grinding or under-grinding, affecting product quality.
[0004] Therefore, there is an urgent need for a pipe end grinding device that can replace manual grinding of pipes. Utility Model Content
[0005] To address the problems mentioned in the background section, this utility model provides a pipe end grinding device to solve the problems of general grinding accuracy and low grinding efficiency in the prior art.
[0006] The aforementioned grinding equipment can only be operated by hand. As the operation time increases, the operator is prone to fatigue, resulting in low grinding efficiency of the pipes. Furthermore, the operator's hand posture also affects the grinding angle of the pipes, causing more burrs and tilting at the ends, which affects the accuracy of the pipes.
[0007] The technical problem to be solved by this utility model is achieved by the following technical solution:
[0008] A pipe end grinding device includes a base and a slide rail and grinding fixture connected to the base. A support platform is slidably connected to the slide rail. A first port for accommodating a workpiece is provided above the support platform. The first port extends through the support platform along the sliding displacement direction. The grinding fixture is located at the other end of the slide rail along the sliding displacement direction of the support platform.
[0009] Furthermore, along the through direction of the first port, the first port is perpendicular to the grinding disc of the grinding fixture.
[0010] Furthermore, the top of the first port is open, and along the sliding displacement direction perpendicular to the support platform, the cross-section of the first port is a V-shape that gradually narrows from top to bottom.
[0011] Furthermore, a pressing fixture is connected to the support platform. The pressing fixture includes a displacement drive, a connecting plate, and a pressing block. The displacement drive is connected to the side of the support platform. The connecting plate is connected to the output end of the displacement drive and is positioned above the first port. The pressing block is connected to the connecting plate and is positioned towards the first port.
[0012] Furthermore, the end of the pressure block facing the first port is provided with a second port, the bottom of which is open and extends through the sliding displacement direction of the support platform.
[0013] Furthermore, along the sliding displacement direction perpendicular to the support platform, the cross-section of the second port is a V-shape that gradually contracts from bottom to top.
[0014] Furthermore, along the sliding displacement direction perpendicular to the support platform, the distance between the two side walls of the second port is less than the distance between the two side walls of the first port.
[0015] Furthermore, the pressure block is made of a flexible material with elasticity.
[0016] Furthermore, the grinding fixture includes a motor, a bracket, and a grinding disc mounted in front of the bracket. The motor's shaft passes through the bracket in a direction parallel to the slide rail and is fixedly connected to the grinding disc.
[0017] Furthermore, the grinding device also includes a limiting pin, which is connected to the base and is located at the end of the slide rail away from the grinding fixture.
[0018] The pipe end grinding fixture provided in the embodiments of this application has at least the following beneficial effects:
[0019] This application ensures that the pipe can move stably and accurately along the predetermined direction of the slide rail by sliding a support platform for positioning the pipe onto the slide rail and setting the grinding fixture at the other end of the slide rail along the sliding displacement direction of the support platform. This achieves precise grinding of the pipe end. When the operator pushes the support platform close to the grinding fixture, the pipe end clamped on it can make flexible contact with the grinding disc, which can protect the pipe surface and improve the grinding accuracy. Through the above settings, this application retains the advantages of manual grinding while ensuring the accuracy and efficiency of equipment grinding. It has the advantages of simple structure, easy operation, high grinding accuracy, and strong practicality. Attached Figure Description

[0031] Example 1
[0032] Figure 1 This is a schematic diagram of the overall structure of a pipe end grinding device according to this application, as shown below. Figure 1 As shown, a pipe end grinding device includes a base 1 and a slide rail 2 and a grinding fixture 4 connected to the base 1. A support platform 3 is slidably connected to the slide rail 2. A first port 31 for accommodating workpieces is provided above the support platform 3. The first port 31 extends through the sliding displacement direction of the support platform 3 and is used to accommodate pipe-type workpieces.
[0033] Furthermore, along the sliding displacement direction of the support platform 3, the grinding fixture 4 is disposed at the other end of the slide rail 2. When grinding is required, the operator can place the pipe-like workpiece on the first port 31 and make one end of the workpiece face the grinding fixture 4. The operator can fix the pipe on the first port 31 by pressing and push the support platform 3 toward the grinding fixture 4 to achieve grinding of the end of the pipe.
[0034] In some preferred embodiments, the grinding device further includes a limiting pin 6, which is connected to the base 1 and is disposed at the end of the slide rail 2 away from the grinding fixture 4. The limiting pin 6 is used to limit the phenomenon of the support platform 3 displacing from the slide rail 2 when it moves in a direction away from the grinding fixture 4, thus preventing the displacement from exceeding the limit.
[0035] In some preferred embodiments, along the through direction of the first port 31, the first port 31 is perpendicular to the grinding disc 43 of the grinding fixture 4 to ensure the perpendicularity of the grinding. During operation, the operator places the pipe at the first port 31, and by utilizing the perpendicularity between the first port 31 and the grinding disc 43, the pipe port and the grinding disc 43 can be ground perpendicularly.
[0036] In some preferred embodiments, the top of the first port 31 is open, and along the sliding displacement direction perpendicular to the support platform 3, the cross-section of the first port 31 is a V-shape that gradually narrows from top to bottom. The V-shaped receiving opening can naturally guide the pipe to be placed in a predetermined direction and can flexibly adapt to pipes of different diameters and models to meet diverse receiving needs.
[0037] In some preferred embodiments, the grinding fixture 4 includes a motor 41, a bracket 42, and a grinding disc 43 mounted in front of the bracket 42. The motor 41 is fixedly connected to the bracket 42, and the rotating shaft of the motor 41 is parallel to the slide rail 2. The rotating shaft of the motor 41 passes through the bracket 42 and is fixedly connected to the grinding disc 43. The rotating shaft of the motor 41 drives the grinding disc 43 to rotate, thereby achieving the grinding of the pipe.
[0038] In some preferred embodiments, the bracket 42 is a bent mounting bracket with a 90-degree angle, and the bend is supported by triangular reinforcing ribs, so that the motor 41 can be safely and reliably fixed in the required position and withstand various forces and vibrations during operation.
[0039] Example 2
[0040] This embodiment is similar in overall structure to Embodiment 1, except that: a pressing fixture 5 is connected to the support platform 3, as shown below. Figure 2 As shown, one end of the pressing tool 5 is connected to the side of the support platform 3, and the other end extends to the top of the first port 31. It moves towards or away from the first port 31, so that the pressing tool 5 can cooperate with the first port 31 of the support platform 3 to clamp the pipe and avoid positional displacement during the pipe grinding process.
[0041] In some preferred embodiments, Figure 3 This is a schematic diagram of the structure of the pressing tool 5 in this application, as shown below. Figure 3 As shown, the pressing fixture 5 includes a displacement drive 51, a connecting plate 52, and a pressing block 53. The displacement drive 51 is connected to the side of the support platform 3. The connecting plate 52 is connected to the output end of the displacement drive 51 and is disposed above the first port 31. The pressing block 53 is connected to the connecting plate 52 and is disposed towards the first port 31. Preferably, the displacement drive 51 is a cylinder. Under the drive of the displacement drive 51, the pressing block 53 moves towards or away from the first port 31. The pressing block 53 is used to cooperate with the first port 31 of the support platform 3 to clamp the pipe.
[0042] In some preferred embodiments, the pressure block 53 is made of a flexible material with elasticity, including materials such as rubber, silicone, cork, and plastic, to prevent the pressure block 53 from damaging the pipe during the pressing process.
[0043] In some preferred embodiments, the pressure block 53 is provided with a second port 54 at one end facing the first port 31. The bottom of the second port 54 is open and extends through the sliding displacement direction of the support platform 3, and is used to cooperate with the first port 31 to form a through clamping opening.
[0044] In some preferred embodiments, along the sliding displacement direction perpendicular to the support platform 3, the cross-section of the second port 54 is a V-shape that gradually narrows from bottom to top, which is used to accommodate pipes of different diameters and models and meet diverse clamping requirements.
[0045] In some preferred embodiments, along the sliding displacement direction perpendicular to the support platform 3, the distance between the two side walls of the second port 54 is less than the distance between the two side walls of the first port 31, such as... Figure 4 As shown, when the pipe diameter is small, the two side walls of the second port can be pressed down into the two side walls of the first port 31 to enhance the wrapping effect when clamping the pipe and increase the clamping stability of the small diameter pipe.
[0046] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
