Description

Technical Field

[0001] The invention relates to the technical field of total stations, in particular to a self-lubricating guide rail with an embedded screw slide. Background Art

[0002] The guide rail embedded screw slide is usually also called the embedded screw module. It is a commonly used linear motion control device, mainly composed of a screw, a guide rail, a slider and a sealing structure. When working, the motor drives the screw to rotate, and the slider screwed with the screw slides linearly on the guide rail. The surface of the guide rail is easily affected by environmental factors such as moisture and oxygen, which can cause rust. Rust not only affects the accuracy and surface quality of the guide rail, but also accelerates the wear of the guide rail. Regularly applying lubricating oil can form a protective film on the surface of the guide rail, effectively isolating air and moisture to prevent the guide rail from rusting;

[0003] Most of the guide rails with embedded screw slides in the prior art require the user to first remove the sealing structure and then apply lubricating oil to the guide rail. The process is cumbersome and the efficiency of applying lubricating oil is low. Although some self-lubricating guide rails with embedded screw slides automatically oil the guide rails by arranging an oiling structure on the outside of the guide rail that moves synchronously with the slider, when applying lubricating oil to the vertically installed guide rails with embedded screw slides, excess lubricating oil will seep from top to bottom along the screw, causing the lubricating oil to drip continuously from the bottom of the screw, affecting the cleanliness of the workbench and wasting the lubricating oil. Summary of the invention

[0004] The object of the present invention is to provide a self-lubricating guide rail embedded screw slide to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A self-lubricating guide rail with built-in screw slide, comprising:

[0007] A bottom plate, with sealing plates 1 fixed on both sides of the bottom plate;

[0008] The slide body is arranged on the top of the bottom plate, and the slide body includes a transmission seat and a support seat respectively fixed at both ends of the bottom plate, a screw rod and two columnar guide rails are rotatably connected between the transmission seat and the support seat, and a slider slidably connected to the columnar guide rail is screwed and connected to the outer side of the screw rod;

[0009] Two oiling modules are provided, which are detachably fixed on the outer side of the sealing plate 1 at the corresponding position. The oiling modules include a crossbeam, and L-shaped blocks 1 and 2 are fixed at both ends of the crossbeam. One end of the L-shaped block 1 is rotatably connected to an inclined shaft rod, and an oiling mechanism is provided between the shaft rod and the slider;

[0010] The first support member is detachably snap-fitted and fixed to the top of the second L-shaped block, and is used to support the shaft rod;

[0011] The second support member is detachably snap-connected and fixed on the top of the second L-shaped block and is used to drive the shaft rod to move.

[0012] Furthermore, a rectangular hole is formed on the outer side of the sealing plate 1, and both ends of the crossbeam are fixed with electromagnets which are adsorbed and fixed to the sealing plate 1.

[0013] Further, the support member 1 comprises:

[0014] A support block is slidably connected to the top of the second L-shaped block;

[0015] The rectangular frame 1 is fixed on the top of the supporting block, and the rectangular frame 1 is rotatably connected to one end of the shaft rod.

[0016] Further, the oiling mechanism comprises:

[0017] An injection cylinder is slidably connected to the top surface of the cross beam, and a piston is slidably connected inside the injection cylinder;

[0018] The piston shaft is fixedly connected to the piston, and one end of the piston shaft that passes through the injection cylinder is fixed with a sleeve ring.

[0019] The invention further comprises: a hose is connected and fixed to the outside of the injection cylinder, a hexagonal block is fixed to one end of the injection cylinder, and an oil outlet pipe connected to the injection cylinder is inserted and fixed inside the hexagonal block.

[0020] Furthermore, the top of the collar is rotatably connected with a clamping block 1 via a rotating shaft, and the clamping block 1 is slidably clamped with the shaft rod.

[0021] Furthermore, round holes are formed on both sides of the slider, rectangular holes two connected to the round holes are formed inside the two sides of the slider, a bent pipe is connected and fixed to the outer side of the rectangular hole two, and the bent pipe is connected and fixed to the oil outlet pipe.

[0022] Furthermore, the second support member comprises:

[0023] Rectangular frame 2, rotatably sleeved on one end of the shaft;

[0024] A telescopic tube is fixed to one end of the second rectangular frame;

[0025] The wedge block is fixed at the other end of the second rectangular frame, and the inclined surface of the wedge block is in sliding contact with the sliding block.

[0026] Furthermore, one end of the shaft rod is rotatably sleeved with a sleeve, the outer side of the sleeve is symmetrically provided with two second clamping grooves, the inner side of the second rectangular frame is symmetrically fixed with two convex shafts, and the convex shafts are rotatably plugged into the clamping grooves.

[0027] Furthermore, the telescopic tube includes a support tube fixedly connected to the second rectangular frame, a slide rod slides inside the support tube, a return spring is fixed between the slide rod and the support tube, and a limiting ring movably connected to the slide rod is fixed on the inner side of the second L-shaped block.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The electromagnet on the oiling module is energized and adsorbed and fixed on the outside of the sealing plate, and the hexagonal block at one end of the injection cylinder is inserted into the hexagonal groove of the slider. When the screw on the slide body drives the slider to move to the left, the slider moves the injection cylinder to the left along the crossbeam. Since an inclined shaft rod is provided on the outside of the crossbeam, the piston shaft on the injection cylinder slides and engages with the shaft rod. During the process of the injection cylinder following the slider to move left, the piston shaft gradually moves the piston into the injection cylinder under the limited sliding action of the shaft rod. The piston pushes the lubricating oil inside the injection cylinder, so that the lubricating oil is dispersed and transported to the outside of the columnar guide rail through the oil outlet pipe, the bent pipe, and the rectangular hole in turn. As the slider slides on the outside of the columnar guide rail, the lubricating oil is evenly and automatically applied to the outside of the columnar guide rail, eliminating the need for manual application of lubricating oil to the guide rail, which is beneficial to improving the efficiency of slide rail oiling.

[0030] 2. By opening a hexagonal groove 2 at one end of the columnar guide rail close to the support seat, an external tool can be used to drive the columnar guide rail to rotate from the position of the hexagonal groove 2 during the process of lubricating the columnar guide rail, so that different areas on the outside of the columnar guide rail can correspond to the rectangular hole 2 at the oil outlet position, which is convenient for the lubricating oil to fully seep to the outside of the columnar guide rail.

[0031] 3. By moving the slider moved to the left end of the columnar guide rail to the right end of the columnar guide rail again, the slider moves the syringe along the cross beam toward the transmission seat, and the piston shaft moves along the shaft toward the transmission seat, so that the piston shaft brings the piston to be gradually pulled out from the syringe. At this time, the hose fixedly connected to the syringe draws oil from the external container into the syringe for storage in the syringe, so that the next time the slider moves from right to left, the syringe still stores lubricating oil that can be sprayed onto the outside of the columnar guide rail. The slider can still apply the oil on the outside of the columnar guide rail for the second time when moving from left to right, thereby achieving the simultaneous suction of lubricating oil for standby during the process of applying lubricating oil to the guide rail.

[0032] 4. When the slide body is installed vertically (the support seat faces the ground, and the transmission seat is directly above the support seat), the rectangular frame 2 is sleeved on one end of the sleeve of the shaft rod, and then the telescopic tube at one end of the rectangular frame 2 is inserted into the limit ring on the L-shaped block 2, and the wedge block is arranged inside the rectangular hole 1 on the sealing plate 1. When the slider moves from right to left, the slider moves along the inclined surface of the wedge block when it moves to the wedge block position, so that the wedge block pushes the rectangular frame 2 outward, and the rectangular frame 2 moves in the direction of the telescopic tube with the shaft rod through the sleeve, so that when the slider moves to the left end position of the columnar guide rail, the inclination angle of the shaft rod gradually decreases, and the gradual decrease in the inclination angle of the shaft rod causes the piston shaft on the shaft rod to push the piston a small distance, thereby causing the injection cylinder to transport a small amount of oil to the lower position of the columnar guide rail, so that the excess oil above the columnar guide rail can seep downward to replenish the lower position of the columnar guide rail. To a certain extent, it prevents a large amount of oil from being directly transported to the columnar guide rail, causing the oil to fall along the columnar guide rail and cause waste, thereby ensuring the cleanliness of the workbench.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] For example, see Figure 1 - Fig.10 In an embodiment of the present invention, a self-lubricating guide rail embedded screw slide comprises a base plate 100, sealing plates 110 are fixed on both sides of the base plate 100, a slide body 200 is fixed on the top of the base plate 100, the slide body 200 comprises a transmission seat 210 and a support seat 220 respectively fixed on both ends of the base plate 100, a screw 230 and two columnar guide rails 240 are rotatably connected between the transmission seat 210 and the support seat 220, a slider 250 slidably connected to the columnar guide rails 240 is screwed and connected to the outer side of the screw 230, and the sealing plate 110 is fixed on the top of the base plate 100. An oiling module 300 is detachably fixed on the outside, and the oiling module 300 includes a crossbeam 310, and an L-shaped block 1 320 and an L-shaped block 2 330 are respectively fixed at both ends of the crossbeam 310. One end of the L-shaped block 1 320 is rotatably connected to an inclined shaft rod 340, and an oiling mechanism 400 is arranged between the shaft rod 340 and the slider 250. A support member 1 500 for supporting the shaft rod 340 is detachably fixed to the top of the L-shaped block 2 330, and a support member 2 600 for driving the shaft rod 340 to move is detachably fixed to the top of the L-shaped block 2 330.

[0046] Specifically, by installing a crossbeam 310 and an inclined shaft rod 340 on the outer side of the slide body 200, a syringe 410 is slidably engaged with the top of the crossbeam 310, and the piston shaft 420 of the syringe 410 is slidably engaged with the shaft rod 340. When the slider 250 on the slide body 200 slides to the left along the columnar guide rail 240, the slider 250 leads the syringe 410 and the piston shaft 420 to slide to the left synchronously. Since the shaft rod 340 is arranged inclined, the piston shaft 420 sliding with the shaft rod 340 pushes the oil inside the syringe 410 through the piston as the slider 250 moves, thereby realizing that the syringe 410 transports the oil to the outer side of the columnar guide rail 240. As the slider 250 slides on the outer side of the columnar guide rail 240, the oil is evenly applied to the outer side of the columnar guide rail 240, eliminating the need for manual disassembly of the slide body 200 for applying the oil, which is beneficial to improving the efficiency of lubricating oil application.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, a transmission plate 254 is fixed to the top surface of the slider 250. The movement of the slider 250 will move the transmission plate 254. The transmission plate 254 is connected to the external device to achieve linear movement of the device. A sealing plate 260 is installed and fixed between the support seat 220 and the transmission seat 210 to facilitate sealing the screw 230 inside the slide body 200.

[0048] In this embodiment, the screw 230 is arranged in the middle of the slide body 200, and the columnar guide rails 240 are arranged on both sides of the slide body 200. The motor 120 fixed at one end of the base plate 100 drives the screw 230 to rotate forward and reverse so that the slider 250 can move stably back and forth linearly on the columnar guide rails 240.

[0049] like Figure 6 As shown, in this embodiment, a rectangular hole 111 is formed through the outer side of the sealing plate 110, and the rectangular hole 111 facilitates one end of the syringe 410 to be plugged into the slider 250, and then moves along the outer side of the slide body 200 as the slider 250 moves.

[0050] like Figure 2 As shown, in this embodiment, a hexagonal groove 2 is provided at one end of the columnar guide rail 240 close to the support seat 220, which is convenient for using an external device to drive the columnar guide rail 240 to rotate from the position of the hexagonal groove 2, so that different areas on the outside of the columnar guide rail 240 can directly contact the oil.

[0051] like Figure 1 and Figure 4As shown, in this embodiment, electromagnets 311 adsorbed and fixed to the sealing plate 110 are fixed at both ends of the crossbeam 310. When lubrication of the slide body 200 is required, the electromagnet 311 is energized to make the electromagnet 311 adsorbed and fixed to the outer side of the sealing plate 110 made of iron material, so that the entire oiling module 300 is installed on one side of the columnar guide rail 240 to be oiled on the slide body 200. The oiling module 300 can be installed on both sides of the slide body 200 at the same time, so as to facilitate the oiling and lubrication of the two columnar guide rails 240 at the same time.

[0052] like Figure 1 , Figure 8 , Fig. 9 As shown, in this embodiment, the support member 500 includes a support block 510 that is slidably engaged with the L-shaped block 330, a rectangular frame 520 is fixed on the top of the support block 510, the rectangular frame 520 is rotatably connected to one end of the shaft 340, and a trapezoidal groove that is slidably engaged with the support block 510 is formed on the top surface of the L-shaped block 330.

[0053] In this embodiment, when the slide body 200 is horizontally installed on the workbench, there is no need to reduce the oil injection amount at one end of the columnar guide rail 240. At this time, the rectangular frame 520 can be slidably sleeved on the outside of the sleeve 341 of the shaft rod 340. The top and bottom of the inner side of the rectangular frame 520 are also fixed with a convex shaft 611. The convex shaft 611 is inserted into the inside of the groove 2 3411 on the outside of the sleeve 341, so that the end of the shaft rod 340 close to the sleeve 341 is limited and fixed on the L-shaped block 2 330, so that the shaft rod 340 maintains the same inclination before and after the slider 250 moves, so that the injection cylinder 410 can evenly transport and apply the oil to the outside of the columnar guide rail 240.

[0054] like Figure 2 , Figure 3 and Fig.10 As shown, in this embodiment, the oiling mechanism 400 includes a syringe 410 that is slidably engaged, a piston is slidably connected inside the syringe 410, a piston shaft 420 that is slidably engaged with the syringe 410 is fixed at one end of the piston, a collar 430 is fixed to one end of the piston shaft 420 that passes through the syringe 410, a clamping block 431 is rotatably connected to the top of the collar 430 through a rotating shaft, the clamping block 431 is slidably engaged with the shaft rod 340, a hose 411 is connected and fixed to the outside of the syringe 410, a hexagonal block 412 is fixed to one end of the syringe 410, an oil outlet pipe connected to the syringe 410 is plugged and fixed inside the hexagonal block 412, a circular hole 251 is opened through both sides of the slider 250, a rectangular hole 252 that is connected to the circular hole 251 is opened inside both sides of the slider 250, a bent pipe 253 is connected and fixed to the outside of the rectangular hole 252, and the bent pipe 253 is connected and fixed to the oil outlet pipe.

[0055] In this embodiment, when the piston shaft 420 moves the piston into the syringe 410, the one-way valve inside the hose 411 connected to the pipe near the syringe 410 prevents the oil from flowing back from the hose 411, and the oil inside the syringe 410 flows along the oil outlet pipe to the inside of the elbow 253. The one-way valve inside the elbow 253 opens to allow the oil to pass through. The oil discharged from the elbow 253 is diffused and transported to the inside of the circular hole 251 through the rectangular hole 252. Since the columnar guide rail 240 is slidably inserted into the inside of the circular hole 251, the oil entering the inside of the circular hole 251 can be transported to the outside of the columnar guide rail 240, which is convenient for applying the oil to the outside of the columnar guide rail 240 as the slider 250 moves.

[0056] In this embodiment, when the piston shaft 420 moves the piston outward, the one-way valve inside the bend 253 is closed, and the one-way valve at the end of the hose 411 is opened, so that the external oil is transported from the hose 411 to the inside of the injection cylinder 410 for standby use.

[0057] In this embodiment, a hexagonal groove is provided on both sides of the slider 250, and a hexagonal block 412 adapted to be plugged into the hexagonal groove is fixed to one end of the injection cylinder 410. After the hexagonal block 412 is plugged into the hexagonal groove, the slider 250 can move with the injection cylinder 410, and after the hexagonal block 412 is plugged into the hexagonal groove, the oil outlet pipe is also plugged and connected with the bend pipe 253.

[0058] like Figure 4 and Figure 6 As shown, in this embodiment, a slot 1 312 is provided on the top of the cross beam 310 , and a block 2 is fixed on the outer side of the injection cylinder 410 , which is slidably engaged with the slot 1 312 , thereby allowing the injection cylinder 410 to move in a stable position on the cross beam 310 .

[0059] like Fig.10 As shown, in this embodiment, a slot three is provided on the outer side of the shaft rod 340 for sliding engagement with a block one 431, so that the piston shaft 420 is not separated from the shaft rod 340. In addition, the piston shaft 420 can rotate on the block one 431 through the ring 430, so that the piston shaft 420 is still slidably engaged with the outer side of the shaft rod 340 when the inclination angle of the shaft rod 340 changes.

[0060] Embodiment 2 is based on embodiment 1 and is designed to prevent the vertically installed slide body 200 from wasting oil during the self-lubricating process.

[0061] like Figure 4 , Figure 5 , Figure 7As shown, in this embodiment, the support member 600 includes a rectangular frame 610 rotatably connected to one end of the shaft 340, a telescopic tube 620 is fixed to one end of the rectangular frame 610, one end of the telescopic tube 620 is detachably plugged and fixed to the L-shaped block 330, and a wedge block 630 is fixed to the end of the rectangular frame 610 that is away from the telescopic tube 620, and the inclined surface of the wedge block 630 intermittently slides against the slider 250.

[0062] Specifically, when it is necessary to lubricate the vertically installed slide body 200, a support member 2600 is installed at one end of the sleeve 341 of the shaft rod 340. The wedge block 630 on the support member 2600 is arranged on the outside of the columnar guide rail 240. When the slider 250 slides from top to bottom to a position close to the wedge block 630, the slider 250 pushes the wedge block 630 to move outward. The wedge block 630 pushes the shaft rod 340 outward through the rectangular frame 2610, thereby reducing the angle at which the shaft rod 340 is tilted. After the tilt angle of the shaft rod 340 is reduced, the piston shaft 420 pushes the piston a small distance as the slider 250 moves downward, so that a small amount of oil in the injection cylinder 410 is transported to the outside of the bottom of the columnar guide rail 240. The excess oil above the columnar guide rail 240 can seep downward to be supplied to the lower position of the columnar guide rail 240, effectively preventing the oil from falling along the columnar guide rail 240 and causing waste.

[0063] In this embodiment, the middle portion of the wedge block 630 is hollowed out to reduce the weight of the wedge block 630. The wedge block 630 will gradually push the rectangular frame 2 610 as the slider 250 moves only when the slider 250 abuts against its inclined surface, thereby pushing one end of the shaft rod 340 to change the inclination angle of the shaft rod 340.

[0064] like Figure 5 , Figure 7 , Fig.10 As shown, in this embodiment, one end of the shaft 340 is rotatably sleeved with a sleeve 341, and two second slots 3411 are symmetrically opened on the outer side of the sleeve 341. Two convex shafts 611 are symmetrically fixed on the inner side of the second rectangular frame 610, and the convex shafts 611 are rotatably plugged into the second slots 3411.

[0065] In this embodiment, one end of the shaft rod 340 is slidably sleeved with a sleeve 341. When the inclination angle of the shaft rod 340 is changed, the shaft rod 340 can slide inside the sleeve 341 to adapt to the change in the length of the shaft rod 340 itself when the wedge block 630 pushes the shaft rod 340 to move. Two second grooves 3411 are symmetrically provided on the outer side of the sleeve 341. The convex shaft 611 can rotate at the end of the second groove 3411 to make the shaft rod 340 in an active rotation on the rectangular frame 610, so as to facilitate pushing the shaft rod 340 from one end of the shaft rod 340, thereby achieving the effect of changing the inclination angle of the shaft rod 340.

[0066] like Figure 5 , Figure 7 As shown, in this embodiment, the telescopic tube 620 includes a supporting tube fixedly connected to the rectangular frame 610, a sliding rod slides inside the supporting tube, a return spring is fixed between the sliding rod and the supporting tube, a limiting ring 331 movably connected to the sliding rod is fixed on the inner side of the L-shaped block 330, and a rubber sleeve is fixed on the inner side of the limiting ring 331.

[0067] In this embodiment, when it is necessary to install the support member 600 above the L-shaped block 330, first, the rectangular frame 610 is inserted into the end position of the slot 3411 of the sleeve 341, and then the slide rod is squeezed to compress the reset spring to shorten the length of the telescopic tube 620, so that the wedge block 630 can be moved to the rectangular hole 111 of the sealing plate 110. Finally, the slide rod is released and fixed to the inside of the limit ring 331.

[0068] In this embodiment, when the slider 250 moves toward the wedge block 630, the rectangular frame 2 610 pushes the shaft rod 340, the inclination of the shaft rod 340 decreases, and the return spring inside the support tube contracts. When the slider 250 gradually moves in the opposite direction and leaves the wedge block 630, the telescopic tube 620 extends under the compression force of the return spring, so that the rectangular frame 2 610 returns to the initial position with the shaft rod 340.

[0069] In the present invention, when it is not necessary to lubricate the guide rails of the slide body 200 with oil, the oiling modules 300 on both sides of the slide body 200 can be removed.

[0070] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and range of equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0071] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
