Inner wrapping type adjustable guide rail plastic pasting structure and method

Abstract

According to the internally-wrapped adjustable guide rail plastic pasting structure and method, a soft belt is directly bonded to a supporting plate, and then the supporting plate is fixed to the corresponding guide rail. The abrasion of the contact surface of the soft belt can be immediately compensated through the longitudinal adjusting bolt and the adjusting cushion block, so that the service life of the soft belt is prolonged; the maintenance and replacement of the soft belt are quicker, and long-time shutdown is avoided; when the soft belt is replaced, the supporting plate is directly detached, so that repeated overturning of the loading part is avoided, and potential safety hazards are eliminated; when the soft belt is installed, external pressure can be loaded conveniently when the soft belt is pasted. The high point of the soft belt can be conveniently found and scraped by using the plane of the lower guide rail as a reference; and the operation difficulty and intensity are reduced, and wide and rapid operation is facilitated.

Description

Technical Field

[0001] The invention belongs to the technical field of precision machining equipment, and in particular relates to an inner-enclosed adjustable guide rail plastic pasting structure and method. Background Art

[0002] In order to improve the friction performance and service life of the sliding guide rail, the existing guide rail plastic-coated structure is: a polytetrafluoroethylene guide rail soft belt (hereinafter referred to as the soft belt) is bonded to the guide rail surface with an adhesive, so that the friction form of the traditional guide rail is changed to a metal-plastic friction pair; the guide rail soft belt is generally fixed on the upper guide rail (moving guide rail or short guide rail) of the sliding guide rail pair, so that it slides in cooperation with the lower guide rail (static guide rail or long guide rail).

[0003] During the actual operation of the equipment, the soft belt is often severely worn due to poor lubrication. In severe cases, the soft belt may fall off, causing direct friction on the metal surface of the guide rail. At the same time, after long-term operation of the equipment, the sealing performance is reduced, and processing debris is easily accumulated on the plastic surface of the guide rail, causing the surface of the soft belt to be strained. When the above situations occur, the only way to restore and repair it is to re-paste the soft belt. Due to the special installation location of the soft belt, when carrying out maintenance work, it is necessary not only to remove a certain part of the equipment as a whole, but also to turn the part over to expose the guide rail bonding surface for cleaning, cleaning, pasting, scraping, etc.

[0004] At the same time, the plastic pasting method mainly relies on manual operation by technicians. Due to human factors such as operating procedures and personal habits, it is very easy to have uneven plastic pasting surfaces and loose adhesion. If the adhesion is not firm, it is necessary to remove it and re-paste it; if the plastic pasting surface is uneven, preliminary manual scraping is required. After the scraping is completed, the component needs to be restored to the installation position for trial operation to find the high point of the plastic pasting surface, and then the component is scraped and polished multiple times on the high point until the plastic pasting surface is completely fitted to the lower guide rail. Since the amount of scraping each time cannot be too large, in actual production, multiple scraping is often required to make the plastic pasting surface meet the use requirements. Repeated scraping not only greatly increases the labor intensity, but also easily causes damage to other components during repeated lifting and flipping. Summary of the invention

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] As shown in the figure, the structural scheme of the present invention is:

[0036] The soft belt of the present invention is not directly bonded to the guide rail, but a support plate as an intermediate component is used to bond the soft belt directly to the support plate, and then the support plate is fixed to the corresponding guide rail.

[0037] In this embodiment, the upper guide rail 1 is used as the installation base of the support plate 3, and the soft belt 5 is bonded to the plate surface of another guide rail (lower guide rail, not shown in the figure) directly below the support plate 3.

[0038] For details, see Figure 2 As shown, a soft belt installation groove 31 is opened on the plate surface of the support plate 3, and the soft belt 5 is adhesively installed in the soft belt installation groove 31. The four sides of the soft belt 31 in the groove are surrounded and limited by the groove wall 310, that is, the soft belt 31 is equivalent to being wrapped in the soft belt installation groove 31.

[0039] Preferably, the wall thickness of the groove walls 310 on the four sides of the flexible belt installation groove 31 is 5 mm, or not less than 5 mm.

[0040] In addition, the depth of the soft belt installation groove 31 should be slightly less than the thickness of the soft belt 5, that is, after the soft belt 5 is adhesively installed in the soft belt installation groove 31, the surface of the soft belt 5 protrudes from the board surface of the support plate 3. Preferably, the depth of the soft belt installation groove 31 is 0.50 mm less than the thickness of the soft belt, so that the soft belt can directly contact the lower guide rail.

[0041] Preferably, in order to enhance the bonding firmness, a grid-type groove (not shown) is processed at the bottom of the soft belt installation groove 31. Preferably, the groove is 1 mm deep and 1 mm wide, and the grid width is 10 mm.

[0042] like Figure 1As shown, the upper guide rail 1 is provided with a support plate receiving groove, and the support plate 3 is installed in the support plate receiving groove. The support plate 3 is clamped and limited at both ends along the sliding direction of the upper guide rail 1 by the stopper 4 fixed to the upper guide rail 1, and the two ends of the support plate 3 in the direction perpendicular to the sliding direction of the upper guide rail 1 are limited by the wall of the support plate receiving groove. Specifically, the stopper 4 on each side and the corresponding end of the support plate 3 can be clamped, or can be integrally formed, or fixed by bolts;

[0043] The stopper 4 on each side is fixed to the upper guide rail by means of a transverse adjustment bolt 6, which makes it convenient to disassemble and install the support plate 3 as a whole from the upper guide rail 1, and also allows the transverse adjustment bolt 6 to fine-tune the transverse position of the support plate 3.

[0044] The block 4 has three functions: first, it blocks and positions the support plate 3; second, the support plate 3 can be laterally adjusted and positioned by using the through hole and threaded hole on the block 4 in conjunction with the lateral adjustment bolt 6; and third, a scraper plate (not shown in the figure) is installed thereon.

[0045] like Figure 1 As shown, the bottom of the upper guide rail 1 pallet receiving groove is also provided with three pad receiving grooves 100, that is, the notch of each pad receiving groove 100 is facing the pallet 3, and each pad receiving groove 100 contains an adjustment pad 2, the lower surface of the adjustment pad 2 abuts against the pallet 3, and the upper surface of the adjustment pad 2 abuts against the top of the screw of the longitudinal adjustment bolt 7 that is threaded through the upper guide rail 1 and extends into the pad receiving groove 100. By screwing the longitudinal adjustment bolt 7, an appropriate downward pressure is applied to the adjustment pad 2, which finally acts on the pallet 3 to adjust the longitudinal geometric relative position of the pallet 3 and compensate for the wear of the soft belt.

[0046] The material of the soft belt 5 is generally polytetrafluoroethylene, which has good plasticity, strong wear resistance, stable physical and chemical forms, easy pasting and cutting, and high machinability.

[0047] After the soft belt 5 on the support plate 3 is scraped and polished, before it is officially put into use, it is necessary to process a lubricating oil channel on the contact surface between it and the lower guide rail, one is to protect the soft belt body, and the other is to reduce the operating load of the equipment; Figure 2 As shown, the lubricating oil channel on the contact surface is composed of a plurality of O-shaped oil grooves 9 arranged crosswise in sequence, combined with Figure 1 As shown, at least two oil filling holes 10 for supplying oil to the lubricating oil channel are also provided on the support plate 3 and the soft belt 5. The oil outlet of the oil filling hole 10 is provided in the O-type oil groove 9, the oil inlet is provided at one end of the support plate 3, and the block 4 is formed with an avoidance groove for avoiding the oil inlet.

[0048] The embodiments of the plastic pasting method based on the plastic pasting structure of the present invention are as follows:

[0049] According to the thickness and width of the soft belt 5, a soft belt installation groove 31 with a thickness less than 0.50mm than the soft belt thickness is processed on the support plate 3, and the groove wall 310 is 5mm wide. In order to enhance the bonding firmness, a grid groove (not shown) is processed at the bottom of the soft belt installation groove 31. Preferably, the groove is 1mm deep and 1mm wide, and the grid width is 10mm.

[0050] The soft tape is pasted into the soft tape installation groove 31 of the support plate 3. In order to prevent the two ends of the soft tape from curling up and coming apart after pasting, pressure blocks (not shown in the figure) are respectively installed at both ends of the soft tape. The pressure of the pressure blocks makes the two ends of the soft tape firmly fit on the support plate.

[0051] After the soft tape is adhered, the soft tape of the pallet is directed toward the lower guide rail and pressed against it, and the pallet is manually pushed to slide back and forth relative to the lower guide rail. The lower guide rail is used as a reference surface to perform a plane inspection, trimming and scraping of the soft tape contact surface on the pallet.

[0052] After scraping and grinding, a lubricating oil channel is machined on the contact surface of the soft belt with the lower guide rail, and oil injection holes for supplying oil to the lubricating oil channel are machined on the soft belt and the support plate;

[0053] A pad receiving groove and a threaded through hole are processed on the upper guide rail, and an adjusting pad 2 is installed in the pad receiving groove; the support plate 3 is installed on the upper guide rail, and the upper surface of the support plate 3 is against the adjusting pad 2; the corresponding longitudinal adjustment bolt 7 is installed at the threaded through hole, and the longitudinal adjustment bolt 7 and the adjusting pad 2 are used to achieve fine-tuning compensation of the support plate.

[0054] The lateral position of the support plate is fixed by means of the stoppers 4 at both ends of the support plate 3 and the lateral adjustment bolts 6;

[0055] The oil filling hole is used to lubricate the lubrication oil channel.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
