Description

Technical Field

[0001] The present invention relates to the technical field of linear guide rail processing, in particular to a processing device with a width detection function for linear guide rail production. Background Art

[0002] Linear guides can generally be divided into three types: roller, ball or cylindrical linear guides. They are mainly used to support and guide units for linear movement and are widely used in various machining fields and high-end precision equipment.

[0003] During the production of linear guides, the width of the guides needs to be inspected. However, currently, this is mostly done through point contact or line contact. Due to the small contact area, this inspection process can easily result in large local forces, causing scratches and other damage. The molding of linear guides requires multiple steps. Because linear guides use channels to guide and limit the sliders, conventional grinding devices can only perform end surface grinding and are unable to simultaneously grind the channels, significantly reducing processing efficiency.

[0004] In addition, during the grinding process of linear guide rails, a large number of metal particles will be generated, which can easily diffuse around the operating space and pose a threat to the health of operators. Summary of the Invention

[0005] The object of the present invention is to provide a processing device with a width detection function for producing linear guide rails to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A processing device with a width detection function for producing linear guide rails, the processing device is used to process the linear guide rails, and includes a bed, a grinding device, a dust collecting device and a conveying device. The grinding device and the bed are tightly connected, the air inlet end of the dust collecting device faces the processing surface of the linear guide rail, the dust collecting device and the grinding device are connected by pipelines, the conveying device and the bed are connected, the linear guide rail is placed on the upper side of the conveying device, and the conveying device and the linear guide rail are connected by transmission.

[0008] The linear guide rail is ground by the processing device. The bed serves as the main installation basis for installing other devices. The workpiece surface is roughly ground by the grinding device, and surface grinding and groove grinding are performed at the same time to improve the grinding efficiency. The grinding debris is collected by the dust collecting device to prevent the metal particles generated by grinding from diffusing in the air and endangering the safety of the operator. The linear guide rail is transported by the conveying device for continuous processing.

[0009] Furthermore, a working chamber is provided on the bed, and a grinding device is placed in the working chamber. The grinding device includes a grinding belt, an adjusting assembly, a sliding member and a detection assembly. The grinding surface of the grinding belt faces the surface of the linear guide rail. The adjusting assembly includes a pressure seat. The pressure seat faces the inner groove of the linear guide rail through the grinding belt. The sliding member and the side of the linear guide rail are in friction contact. The detection assembly includes a mounting seat, a guide column, a coil and a transmission plate. One side of the mounting seat is fastened to the wall of the working chamber. A detection chamber is provided on the mounting seat. The coil, guide column and transmission plate are placed in the detection chamber. The center line of the guide column coincides with the center line of the coil. The sliding member and the transmission plate are transmission-connected. The transmission plate is fastened to the guide column on the side away from the sliding member. The guide column is made of a magnetic material. A sliding surface is provided on the mounting seat. The sliding surface is located on the side close to the sliding member. The roughness of the sliding surface gradually decreases from top to bottom, and the sliding surface is arranged obliquely.

[0010] The dust collecting device includes a dust collecting pipe, which faces the processing surface of the linear guide rail. The conveying device includes a conveying chain, which is slidably connected to the bottom surface of the working chamber. A plurality of positioning pins are provided on the outside of the conveying chain, which are transmission-connected to the linear guide rail.

[0011] During transmission: the positioning pin is inserted into the hole of the linear guide.

[0012] The bed provides processing space through the working chamber for installing the grinding device. The grinding device uses a grinding belt as a grinding tool. The outer side of the grinding belt is the grinding surface, which is kept in a tensioned state by two tensioning wheels and two pressure seats. The pressure seat presses the grinding belt partially into the linear guide groove. A grinding motor is provided on one side of the tensioning wheel, which drives the tensioning wheel to rotate, thereby driving the grinding belt to rotate. The grinding belt is made of flexible material. Under the action of tension, the top surface, two side surfaces and groove of the linear guide are polished at the same time. The point polishing efficiency is improved through the integrated polishing program. The pressure seat is designed according to the shape of the groove and is a replaceable module. The sliding part is in friction contact with the side wall of the linear guide, and one side of the sliding part is in friction contact with the sliding surface of the mounting seat. The sliding surface is arranged tilted and the roughness is gradually set. When the width of the side wall of the linear guide is qualified During the movement of the linear guide, the friction force applied to the sliding part causes the sliding part to be located at a fixed level on the sliding surface. When the local width is large, since the gap between the sliding part and the linear guide remains unchanged, the friction force applied by the linear guide on the sliding part increases, and thus under the action of the friction force on the lower side, the sliding part is driven to move up along the sliding surface until it moves to a level where it re-enters a balanced state. During the movement of the sliding part, the guide column is pushed to move by the transmission plate, so that the guide column moves along the axis of the coil, causing the coil to cut the magnetic flux lines and generate an induced current. The magnitude of the induced current is positively correlated with the width of the linear guide, that is, the larger the linear guide, the greater the induced current generated, thereby performing real-time detection of the width of the linear guide. During the chain transmission process, the conveyor chain drives the linear guide to move by inserting the positioning pin into the hole of the linear guide.

[0013] Furthermore, the dust collecting device also includes a fan, a guide pipe, a fan and a working chamber.

[0015] The air inlet of the fan is connected to the dust collecting pipe, so that a negative pressure end is formed at the inlet of the dust collecting pipe. Under the action of the pressure difference, the grinding particles are collected to prevent them from diffusing in the surrounding air. At the same time, the intensified air flow will force air cooling on the grinding part of the linear guide to prevent heat accumulation and expansion, which will affect the width detection accuracy. Through the split design of the sliding parts, when performing width detection, the two slides are always tightly attached to the side walls of the linear guide, and surface contact detection is performed to prevent detection damage; the grinding particles collected by the fan are sent into the dust inlet groove of the slide through the guide pipe, and the dust inlet groove is connected to the lubrication gap between the slide and the side wall of the linear guide, and a certain amount of grinding particles is transported into the dust inlet groove through air diversion. When the grinding particles enter the lubrication gap, the slide and the linear guide are subjected to dynamic friction lubrication, which reduces friction, improves the smoothness of the linear guide movement, and improves detection efficiency.

[0016] Furthermore, a driving cavity is provided on the bed, and the conveying device also includes a sprocket and a driving motor, the sprocket and the driving motor are placed in the driving cavity, the output end of the driving motor is transmission-connected to the sprocket, and the sprocket is transmission-connected to the conveying chain.

[0017] The drive motor is installed through the drive cavity. The drive motor outputs torque to drive the sprocket to rotate, thereby making the conveyor chain rotate and continuously loading and unloading the linear guide rail for grinding, reducing manual participation and improving the processing efficiency of the linear guide rail.

[0018] Furthermore, the adjustment component also includes an abutment cylinder, the abutment cylinder body and the working chamber wall are tightly connected, the abutment cylinder output end and the pressure seat are transmission connected, and the pressure seat is eccentrically arranged at the abutment cylinder output end.

[0019] The abutment cylinder is installed in the working chamber and is used to drive the pressure seat to move and adjust the relative distance between the two pressure seats, so that it is suitable for the processing of linear guide rails of different widths. The eccentric arrangement of the pressure seat prevents the abutment cylinder and the grinding belt from causing motion interference.

[0020] As an optimization, the sliding element also includes a double-ended cylinder. The double-ended cylinder body is tightly connected to the base, and the two output ends of the double-ended cylinder are respectively connected to the two slides. The double-ended cylinder is mounted on the base, and the two output ends of the double-ended cylinder maintain transmission with the slides, adjusting the relative distance between the two slides, suitable for testing linear guides of different specifications.

[0021] As an optimization, a transmission groove is provided on the transmission plate, which is arranged vertically, and one end of the base is inserted into the transmission groove. Through the transmission groove provided on the transmission plate, when the base is tilted and moved upward, only horizontal displacement is transmitted, and vertical movement is sliding in the transmission groove.

[0022] As an optimization, the dust collecting device also includes a waste pipe, which is located at the end of the lubrication gap and is connected to the negative pressure air source. The waste pipe collects grinding particles generated by dynamic friction to prevent dispersion.

When the local width is large, since the gap between the sliding part and the linear guide rail remains unchanged, the friction force applied by the linear guide rail to the sliding part increases, thereby driving the sliding part to move up along the sliding surface under the action of the friction force on the lower side until it moves to a level where it re-enters a balanced state. During the movement of the sliding part, the guide post is pushed to move by the transmission plate The movement causes the guide column to move along the axis of the coil, causing the coil to cut the magnetic flux lines and generate an induced current. The magnitude of the induced current is positively correlated with the width of the linear guide rail. That is, the larger the linear guide rail is, the larger the induced current is, thereby performing real-time detection of the width of the linear guide rail. Through the split design of the sliding part, when performing width detection, the two slides are always tightly attached to the side walls of the linear guide rail, and surface contact detection is performed to prevent detection damage. Through air diversion, a certain amount of grinding particles are transported into the dust inlet groove. When the grinding particles enter the lubrication gap, the slide and the linear guide rail are subjected to dynamic friction lubrication, thereby reducing friction, improving the smoothness of the linear guide rail, and improving detection efficiency.
