Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a laser cutting equipment with a lubricating oil injection device. Background Technology

[0002] During operation, key components of a laser cutting machine, such as guide rails, gears, and racks, undergo frequent movement and meshing, generating friction. Prolonged friction leads to surface wear on these components, affecting the hardness and lifespan of the cutting equipment. Therefore, a lubrication pump is needed to supply lubricant to these key components, creating a protective film on their surfaces to significantly reduce the coefficient of friction, effectively prevent wear, and extend the equipment's lifespan.

[0003] Currently, the traditional lubrication method involves directly aligning the outlet end of the hose with the component and dripping lubricant onto it. However, since the lubricant is concentrated in a relatively small area, it is necessary to wait for the lubricant to slowly flow outwards before it can reach the surrounding areas. Moreover, the process is quite random, and there may be many areas that are not covered by lubricant. Furthermore, the lubrication effect of the traditional lubrication method is poor, and each lubrication operation requires a large amount of lubricant to complete, resulting in a large amount of waste oil. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a laser cutting equipment with a lubricating oil injection device. The quick-release oil injection device not only solves the problem that the randomness of the lubricating oil flow may result in many parts not being lubricated, but also meets the requirements of low oil consumption, good lubrication effect and easy maintenance.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A laser cutting device with a lubricating oil injection device includes a cutting table and a gantry mounted on the cutting table. Each end of the gantry is provided with a slide table. The slide table is slidably mounted on the top of the cutting table through a transmission assembly. A lubrication pump is installed on the slide table. The lubrication pump is connected to an oil injection device for adding lubricating oil to the transmission assembly.

[0007] The oil injection device includes a distributor mounted on a slide. The oil inlet of the distributor is connected to the oil outlet of the lubrication pump through an oil outlet hose. The distributor is mounted on the slide via a quick-change mechanism, and an oil distribution brush is installed at the bottom of the distributor.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] The quick-change mechanism includes a locking seat and a locking pin that are compatible with each other. The upper end of the locking pin is fixed to the distributor. The locking pin has a locking groove arranged in an annular pattern on its circumferential surface near the lower end. A push plate frustum is fixed to the lower end of the locking pin. The upper diameter of the push plate frustum is larger than the lower diameter.

[0010] Further optimization: The locking seat has a locking cavity inside. One end of the locking pin with the push plate frustum is inserted into the locking cavity through the top opening of the locking cavity. An ejector spring is fixed on the bottom wall of the locking cavity. The position of the ejector spring is adapted to the locking pin. A locking arc plate is slidably installed in the locking cavity in the horizontal direction. The locking arc plate is adapted to the locking groove. A locking spring is installed between the outer wall of the locking arc plate and the locking cavity.

[0011] Further optimization: The outer wall of the locking arc plate is provided with vertical plates at intervals, the vertical plates are fixedly connected to the locking arc plate, and a slip ring is slidably installed vertically at the upper end of the locking cavity. Two pushing wedges that cooperate with the vertical plates are fixed at the bottom of the slip ring.

[0012] Further optimization: At least two vertical connecting rods are fixed to the top of the slip ring. The upper end of the vertical connecting rod extends out of the locking seat. The end of the vertical connecting rod extending out of the locking seat is fixed to a release plate. An opening is provided in the middle of the release plate for the passage of the locking pin.

[0013] Further optimization: At least one drip head is installed at the bottom of the distributor, and the oil outlet hose distributes the lubricating oil evenly into each drip head through the distributor.

[0014] Further optimization: The transmission assembly includes a meshing transmission gear and a fixed rack. The transmission gear is rotatably mounted on the gantry frame, and the fixed rack extends along the sliding direction of the slide table and is fixed to the cutting table.

[0015] Further optimization: A guide rail fixed to the cutting table is provided on one side of the fixed rack. The guide rail extends along the length of the fixed rack, and the bottom of the slide table is slidably mounted on the guide rail.

[0016] Further optimization: Each of the fixed rack and guide rail is provided with a cloth oil brush, and the lower end of the cloth oil brush is pressed against the top of the fixed rack and guide rail.

[0017] The present invention adopts the above technical solution and has the following beneficial effects:

[0018] 1. The present invention adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. It uses multiple oil dripping heads to realize multi-point dripping of lubricating oil. At the same time, the oil brush follows the gantry frame to reciprocate and spread the lubricating oil dripped onto the fixed rack and guide rail, so that the lubricating oil can be evenly distributed to every position of the fixed rack and guide rail. This solves the problem that the randomness of the lubricating oil flow may result in many parts not being lubricated.

[0019] 2. Compared to the traditional oiling method, the method of using a cloth oil brush to spread the lubricating oil can complete the lubrication work with a small amount of lubricating oil, thus meeting the needs of low oil consumption and good lubrication effect.

[0020] 3. The quick-change, detachable distributor facilitates the cleaning, maintenance, and replacement of the subsequent oil brush and drip head. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-4 As shown in the figure, a laser cutting device with a lubricating oil injection device includes a cutting table 1 and a gantry 2 installed on the cutting table 1. A slide table 3 is provided at each end of the gantry 2. The slide table 3 is slidably installed on the top of the cutting table 1 through a transmission assembly 4. A lubrication pump 5 is installed on the slide table 3. The lubrication pump 5 is connected to an oil injection device for adding lubricating oil to the transmission assembly 4.

[0029] In this embodiment, the oil inlet of the lubrication pump 5 is connected to a lubrication oil tank.

[0030] In this embodiment, the structure, installation principle, and operating principle of the cutting table 1, gantry frame 2, and lubrication pump 5 are all existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0031] like Figure 3 and Figure 4 As shown, the oil injection device includes a distributor 8 mounted on the slide 3.

[0032] In this embodiment, the shunt 8 is a commercially available shunt, whose internal structure and principle are existing technologies and will not be described in detail here.

[0033] The oil inlet of the distributor 8 is connected to the oil outlet of the lubrication pump 5 through the oil outlet hose 6.

[0034] In this embodiment, the fixed installation structure between the oil outlet hose 6, the distributor 8, and the lubrication pump 5 is existing technology and will not be described in detail here.

[0035] The distributor 8 is mounted on the slide table 3 via the quick-change mechanism 7, and an oil brush 9 is installed at the bottom of the distributor 8.

[0036] In this embodiment, the oil brush 9 is used to evenly spread the lubricating oil on the fixed rack 402 and guide rail 403 to every part of the fixed rack 402 and guide rail 403, which effectively solves the problem that the strong randomness of the lubricating oil flow leads to unlubricated positions on the fixed rack 402 and guide rail 403, thereby improving the lubrication effect on the fixed rack 402 and guide rail 403.

[0037] Moreover, compared with traditional oil injection methods, this invention requires less lubricating oil during lubrication operations, thus generating less waste oil and effectively reducing the amount of waste oil produced, thereby reducing the cost of lubrication operations.

[0038] like Figure 3 and Figure 4As shown, the quick-change mechanism 7 includes a locking seat 701 and a locking pin 702 that are adapted to each other. The upper end of the locking pin 702 is fixed to the distributor 8. The locking pin 702 has a locking groove 703 arranged in an annular pattern on its circumferential surface near the lower end. The lower end of the locking pin 702 is fixed with a push plate frustum 704. The upper diameter of the push plate frustum 704 is larger than the lower diameter.

[0039] In this embodiment, the distributor 8 is detachably mounted on the slide table 3 via the quick-change mechanism 7. Therefore, production personnel can quickly remove the distributor 8 as needed to facilitate cleaning, maintenance, and replacement of the oil brush 9 and the drip head 801.

[0040] The locking seat 701 has a locking cavity 705 inside. One end of the locking pin 702, which is provided with a push plate frustum 704, is inserted into the locking cavity 705 through the top opening of the locking cavity 705. An ejector spring 706 is fixed on the bottom wall of the locking cavity 705. The position of the ejector spring 706 is adapted to the locking pin 702. A locking arc plate 707 is slidably installed in the locking cavity 705 in the horizontal direction. The locking arc plate 707 is adapted to the locking groove 703. A locking spring 708 is installed between the outer wall of the locking arc plate 707 and the locking cavity 705.

[0041] like Figure 4 As shown, the outer wall of the locking arc plate 707 is provided with vertical plates 709 at intervals. The vertical plates 709 are fixedly connected to the locking arc plate 707. A slip ring 710 is slidably installed vertically at the upper end of the locking cavity 705. Two push wedges 711 that cooperate with the vertical plates 709 are fixed at the bottom of the slip ring 710.

[0042] Furthermore, at least two vertical connecting rods 712 are fixed to the top of the slip ring 710. The upper end of the vertical connecting rod 712 extends out of the locking seat 701. The end of the vertical connecting rod 712 extending out of the locking seat 701 is fixed to a release plate 713. The middle part of the release plate 713 is provided with an opening for the locking pin 702 to pass through.

[0043] The procedure for disassembling and assembling splitter 8 is as follows:

[0044] First, press down on the release plate 713. The release plate 713 drives the vertical connecting rod 712 and the push wedge 711 to move downward. The push wedge 711 pushes the vertical plate 709 and the locking arc plate 707 to move outward, so that the locking arc plate 707 exits from the locking groove 703 on the locking pin 702. The locking pin 702 moves upward under the elastic force of the push-out spring 706, and the diverter 8 moves upward accordingly, thus unlocking the diverter 8.

[0045] Afterwards, the production staff can lift the unlocked distributor 8 upwards and remove it, and then clean, inspect, and maintain the oil brush 9 and oil drip head 801 at the bottom of the distributor 8.

[0046] After completing cleaning, inspection, and maintenance operations, the production personnel reinsert the diverter 8 into the corresponding opening on the slide table 3 and align the locking pin 702 with the corresponding locking cavity 705. They then press the diverter 8 downwards to insert the locking pin 702 into the locking cavity 705. The push plate frustum 704 at the end of the locking pin 702 pushes the two locking arc plates 707 to move outwards. The push plate frustum 704 passes smoothly between the two locking arc plates 707 and continues to move downwards, compressing the ejector spring 706.

[0047] When the locking groove 703 moves to the position aligned with the locking arc plate 707, the two locking arc plates 707 move inward and are inserted into the locking groove 703 simultaneously under the elastic force of the locking spring 708, thereby achieving the fixed installation of the diverter 8.

[0048] like Figures 1-3 As shown, at least one drip head 801 is installed at the bottom of the distributor 8, and the oil outlet hose 6 distributes the lubricating oil evenly into each drip head 801 through the distributor 8.

[0049] In this embodiment, the structure, principle and installation method of the oil drip head 801 are all existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0050] like Figure 1 and Figure 2 As shown, the transmission assembly 4 includes a transmission gear 401 and a fixed rack 402 that mesh with each other. The transmission gear 401 is rotatably mounted on the gantry frame 2, and the fixed rack 402 extends along the sliding direction of the slide table 3 and is fixed on the cutting table 1.

[0051] In addition, a guide rail 403 fixed to the cutting table 1 is provided on one side of the fixed rack 402. The guide rail 403 extends along the length of the fixed rack 402, and the bottom of the slide table 3 is slidably mounted on the guide rail 403.

[0052] The fixed rack 402 and the guide rail 403 are respectively provided with an oil brush 9, and the lower end of the oil brush 9 presses against the top of the fixed rack 402 and the guide rail 403.

[0053] The method of lubrication operation using this utility model is as follows: the lubrication pump 5 is used to pump the lubricating oil in the lubricating oil tank into the distributor 8, and the lubricating oil in the distributor 8 then drips drop by drop through the oil drip head 801 onto the corresponding fixed rack 402 and guide rail 403 below; at the same time, the gantry 2 drives the oil brush 9 to reciprocate, and the oil brush 9 brushes over every position on the top of the corresponding fixed rack 402 and guide rail 403.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
