Abstract

The invention discloses a ceramic tube outer circle grinding process. The up and down strokes of a Z-axis driving device are set in advance by a control device. After one adjustment, ceramic tubes of the same type can be processed continuously. In the rising standby state, the ceramic tube is sleeved on a sliding positioning member. The start switch is pressed, and the Z-axis driving device drives the sliding positioning member to start descending through the descending stroke set in advance by the control device, so that one side surface of the outer diameter of the ceramic tube contacts the grinding wheel, and at the same time, the other pair of side surfaces of the outer diameter of the ceramic tube contacts the abutting driving wheel. The ceramic tube is driven to rotate at a uniform speed with the sliding positioning member as the center line to process the outer diameter surface of the ceramic tube. After the processing is completed, the control device controls the sliding positioning member to rise to the standby state, and the processed ceramic tube can be removed at this time. It does not need to be clamped, and only the ceramic tube needs to be sleeved on the sliding positioning member. The efficiency is high. When processing the outer circle, the concentricity and parallelism of the processed outer diameter of the ceramic tube are guaranteed, and the product qualification rate is high.

Description

Technical Field

[0001] The invention relates to the field of ceramic tube outer circle grinding technology, in particular to a ceramic tube outer circle grinding technology. Background Art

[0002] The surface of the die-cast ceramic tube is uneven, the outer diameter size varies greatly, and the outer diameter and inner diameter are eccentric. When making precision parts, it is necessary to locate the inner hole of the ceramic tube and perform outer circle processing to achieve the required outer diameter size and solve the problem of inner and outer diameter eccentricity.

[0003] Because the strength of ceramic tubes is not high before sintering, they are easy to break and difficult to clamp and process. There are currently two ways to solve this process in the field: 1. Lathe processing, clamp one end of the steel core on the lathe's claws, put the ceramic tube to be processed on the steel core, and use the lathe tailstock to support the other end of the steel core for turning. Since the ceramic tube cannot be clamped directly, the rotation of the ceramic tube depends entirely on the friction between the inner diameter and the steel core. The outer diameter of the ceramic tube varies greatly. When the turning amount is too large, the friction between the ceramic tube and the steel core is not enough and it is easy to slip, resulting in the scrapping of the ceramic tube. The scrap rate is high, and each ceramic tube needs to be processed The tailstock of the lathe needs to be moved back, which is inefficient. 2. Centerless grinder processing: When the centerless grinder processes the outer diameter, when the outer diameter difference is large, the ceramic tube is easy to burst, and the eccentricity problem cannot be solved, and the defective rate is high.

[0004] Later, a kind of dry-pressed ceramic tube outer circle grinding equipment appeared on the market, such as CN210388553U, which includes a frame, a rotating shaft is installed at the left end of the frame, and a blind hole with a square cross-section is opened on the right side of the rotating shaft; a support rod is inserted in the blind hole, and the right end of the support rod is placed on the frame; two left and right fixing sleeves are threadedly connected to the support rod; the inner side of the fixing sleeve is a conical surface; the frame is provided with left and right guide rails, and a slider that can move left and right is provided on the guide rail, and a mounting plate that can move forward and backward along the slider is installed on the slider; the mounting plate and the slider are positioned by a clamping bolt; the mounting plate is installed There is a rotatable grinding wheel. You need to loosen the screws first so that the support rod can be removed, and then rotate the fixing sleeve on the right to remove the fixing sleeve, and then you can put the ceramic tube on the support rod; after the ceramic tube is installed, screw the fixing sleeve on the right onto the support rod again, and clamp the left and right fixing sleeves at the left and right ends of the ceramic tube, so that the ceramic tube can be fixed to the support rod. Although it solves the problem that ceramic tubes on the market are easy to squeeze and burst, it cannot solve the problem of eccentricity. However, the ceramic tube of this ceramic tube outer circle grinding equipment is complicated to install. When disassembling or assembling, you need to remember the different operations during installation and disassembly, which is easy to mix up.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0006] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a ceramic tube outer circle grinding process, which sets the up and down stroke of the Z-axis drive device in advance through the control device, so that it is in a convenient position for picking up and placing products when in the rising standby state; after a good adjustment, the same type of ceramic tubes can be processed continuously, and it does not need to be clamped, and it only needs to be sleeved on the sliding positioning part, which is efficient. When processing the outer circle, the concentricity and parallelism of the outer diameter of the ceramic tube can be guaranteed, and the product qualification rate is high, which effectively solves the problem that the installation of ceramic tubes in traditional technology is complicated, and when disassembling or assembling, it is necessary to remember different operations during installation and disassembly, which is easy to mix up. In particular, it has a simple structure and is easy to assemble or disassemble, which is suitable for popularization and application.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A ceramic tube outer circle grinding process, first, the efficiency is adjusted: the up and down strokes of the Z-axis drive device are set in advance by the control device, so that the rising standby state is in a convenient position for picking up and placing products; after the efficiency is adjusted once, the same type of ceramic tubes can be processed continuously, including the following steps:

[0009] Step 1, in the rising standby state, put the ceramic tube into the sliding positioning piece;

[0010] Step 2, press the start switch on the machine, and the Z-axis driving device drives the sliding positioning member to start descending through the descending stroke set in advance by the control device, so that one side of the outer diameter surface of the ceramic tube contacts the grinding wheel, and at the same time, the other pair of side surfaces of the outer diameter surface of the ceramic tube contacts the abutting driving wheel;

[0011] Step 3, relying on the contact friction between the abutting driving wheel and the ceramic tube, the ceramic tube is driven to rotate at a constant speed with the sliding positioning piece as the center line, so as to process the outer diameter surface of the ceramic tube;

[0012] Step 4: After the processing is completed, the control device controls the sliding positioning member to rise to a standby state, at which time the processed ceramic tube can be removed.

[0013] As a preferred solution, in step 2, when driving the sliding positioning member to descend, it first descends at a 1st speed, and when it approaches the grinding wheel grinding mechanism, it starts to descend at a 2nd speed, and the 2nd speed is set to decelerate at a uniform speed until the ceramic tube on the sliding positioning member is in contact with the driving wheel.

[0014] As a preferred solution, in step 1, first turn on the power switch of the equipment, the grinding wheel starts to rotate, the abutting driving wheel starts to rotate, and then the ceramic tube is sleeved on the sliding positioning piece.

[0015] As a preferred solution, in step 2, the sliding positioning member is driven to descend to the horizontal diameter of the grinding wheel so that one side of the outer diameter surface of the ceramic tube contacts the grinding wheel.

[0016] As a preferred solution, in step 2, both the 1st speed and the 2nd speed can be set on the touch screen of the control device.

[0017] As a preferred solution, the parallelism between the axial center line of the grinding wheel and the axial center line of the sliding positioning member can be adjusted by a parallelism mechanism, so that the diameter accuracy of both ends of the processed ceramic tube is consistent.

[0018] As a preferred solution, the position of the ceramic tube to be processed can be adjusted by the X-axis adjustment mechanism to accommodate the processing of batches of products of different lengths.

[0019] As a preferred solution, a Y-axis adjustment mechanism is used to adapt to different diameter sizes of ceramic tubes that need to be processed.

[0020] As a preferred solution, the inclination of the abutting driving wheel is adjusted to adjust the tightness of the fit between the abutting driving wheel and the ceramic tube, thereby ensuring the concentricity of the inner and outer diameters of the ceramic tube.

[0021] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly does not need to be clamped, and only needs to put the ceramic tube into the sliding positioning part, which is highly efficient. When processing the outer circle, the concentricity and parallelism of the outer diameter of the ceramic tube can be guaranteed, and the product qualification rate is high. It effectively solves the problem that the installation of ceramic tubes in traditional technology is complicated, and when disassembling or assembling, it is necessary to remember different operations during installation and disassembly, which is easy to mix up. In particular, it has a simple structure and is easy to assemble or disassemble, which is suitable for promotion and application.
