[0001] The present invention relates to the technical field of laser cutting, and particularly to a raw material laser cutting device for the production of drawer guides. Background Art

[0002] As a fast and efficient processing method, laser cutting has been widely used in various industrial fields. It mainly uses a laser generator, a beam expander, a focusing lens, a workbench, and a clamping device to process workpieces.

[0003] In the prior art, Chinese invention with the publication number CN108161244A discloses a rotatable chuck for laser cutting. By setting a driving ring, the forward thrust of the cylinder is converted into the clamping force of the clamping jaws inward to clamp the workpiece to be processed.

[0004] Drawer guides are mostly cold-rolled from thin steel plates, and their cross-section is in a "C" shape. The holes and grooves on the surface of the drawer guides need to be cut by laser. For the "C"-shaped drawer guides, traditional clamping devices are prone to cause deformation of the drawer guides when clamping from the side, thus affecting subsequent use. Therefore, the present invention proposes a raw material laser cutting device for the production of drawer guides to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a raw material laser cutting device for the production of drawer guides to solve the problem that traditional clamping devices are prone to cause deformation when clamping the drawer guides from the side as mentioned in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A raw material laser cutting device for the production of drawer guides, including a frame. A laser cutting head is installed on the front of the frame. A guide rail workpiece is arranged below the laser cutting head. A protective sleeve is fixedly installed on the frame.

A worm is rotatably installed on the side surface of the belt rack, and the two ends of the worm are respectively meshed and driven with the two worm wheels.

[0010] Preferably, a vertical waist-shaped hole is formed through the side surface of the end of the belt rack.

An expansion member fixed to the rotating ring is arranged above the cross bar, and the movable end of the expansion member presses on the upper surface of the belt rack.

[0011] Preferably, annular baffles are fixedly sleeved at both ends of the cross bar. The two annular baffles respectively fit against the side surfaces of both ends of the belt rack, and the diameter of the annular baffle is larger than the inner wall width of the vertical waist-shaped hole.

[0012] Preferably, limiting sliding grooves are formed at both ends of the surface of the cross beam. A clamping groove is formed at the lower end of the承接滑块 (it seems there is a typo here, assuming it should be a specific component name). The承接滑块 is located in the inner cavity of the limiting sliding groove, and the clamping groove is stuck on the outer side of the cross beam.

[0013] Preferably, side grooves are formed on both side surfaces of the cross beam. A convex plate is arranged on the side surface of the linkage plate close to the cross beam, and a tooth groove is formed in the middle of the convex plate. The convex plate is located in the inner cavity of the side groove and is adapted to it. An avoidance groove adapted to the linkage plate is formed in the inner wall of the clamping groove.

[0014] Preferably, a thrust spring is fixedly installed on the inner wall of one end of the two limiting sliding grooves close to each other.

DETAILED DESCRIPTION OF THE INVENTION

[0029] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0030] See also Figures 1 to 8 , the present invention provides a technical solution:

[0031] Embodiment 1, a raw material laser cutting device for producing drawer guide rails, includes a frame 1 and a pressing belt 6.

[0032] Specifically, a laser cutting head 4 is installed on the front of the frame 1, and a guide rail workpiece 3 is arranged below the laser cutting head 4. The laser cutting head 4 can perform cutting processing on the surface of the guide rail workpiece 3 to form the holes and grooves actually required. A protective sleeve 2 is fixedly installed on the frame 1. The protective sleeve 2 is located on a side of the frame 1 away from the laser cutting head 4 to avoid collision with the laser cutting head 4. The guide rail workpiece 3 moves through the center of the protective sleeve 2. Two rotating rings 5 ​​are provided on the outer side of the guide rail workpiece 3, and the rotating ring 5 is rotatably installed in the inner cavity of the protective sleeve 2. When the rotating ring 5 rotates, the guide rail workpiece 3 can be driven to rotate accordingly, thereby changing the angle of the guide rail workpiece 3, which is convenient for the laser cutting head 4 to perform cutting processing on the side of the guide rail workpiece 3;

[0033] Secondly, a crossbeam 51 is fixedly installed in the inner cavity of the rotating ring 5, and two symmetrically distributed receiving slide blocks 7 are slidably arranged on the crossbeam 51. The guide rail workpiece 3 is opened downward and pressed on the receiving slide block 7 from top to bottom. The two receiving slide blocks 7 respectively receive the two side edges of the opening end of the guide rail workpiece 3. Since the two receiving slide blocks 7 are symmetrically distributed, the symmetry axis surface of the guide rail workpiece 3 can coincide with the center of the rotating ring 5. When the rotating ring 5 rotates, the guide rail workpiece 3 can always be located directly below the laser cutting head 4 without position displacement. A central gear 512 is rotatably installed in the middle of the crossbeam 51, and linkage plates 71 are meshed on both sides of the central gear 512. The two linkage plates 71 are fixedly connected to the side surfaces of the two receiving slide blocks 7, respectively, and combined with Figure 6 and Figure 7 It can be seen that when the central gear 512 rotates, the two linkage plates 71 can rotate synchronously and in the opposite direction, thereby driving the two receiving slide blocks 7 to keep sliding synchronously and in the opposite direction, so as to change the spacing between the two receiving slide blocks 7 to adapt to guide rail workpieces 3 of different widths;

[0034] In addition, the clamping belt 6 is located between the two rotating rings 5 ​​and is pressed on the middle surface of the guide rail workpiece 3. The surface of the clamping belt 6 is soft. After clamping the guide rail workpiece 3, a large friction force can be generated between the surface of the guide rail workpiece 3, thereby preventing the guide rail workpiece 3 from sliding easily along its own length direction. Only when the clamping belt 6 works to transmit and convey, the guide rail workpiece 3 can be transported accordingly.

[0035] In order to realize the positioning and conveying of the guide rail workpiece 3, the present application also has a belt rack 61 arranged on the outer side of the compression belt 6. The belt rack 61 is mainly used to install and position the conveying roller of the compression belt 6 to prevent the compression belt 6 from loosening. Two worm gears 63 are installed on the side of the belt rack 61, and the two worm gears 63 are respectively fixedly connected to the two conveying rollers of the compression belt 6. A worm 64 is rotatably installed on the side of the belt rack 61, and the two ends of the worm 64 are respectively meshed with the two worm gears 63 for transmission. Figure 4 As shown, the worm 64 is driven to rotate by a motor. When the worm 64 rotates, the meshing transmission with the worm wheel 63 can drive the two worm wheels 63 to rotate synchronously in the same direction, thereby realizing the conveying transmission of the clamping belt 6, and when the worm 64 stops rotating, the worm wheel 63 is limited by the worm 64 and cannot rotate. Therefore, the clamping belt 6 can ensure the stable position of the guide rail workpiece 3 through friction.

[0036] In order to press the guide rail workpiece 3, the present application also has a vertical waist hole 62 penetrating the side of the end of the belt frame 61, and a crossbar 53 parallel to the crossbeam 51 is fixed to the inner cavity of the rotating ring 5, and the crossbar 53 movably penetrates the vertical waist hole 62, such as Figure 4 and Figure 5 As shown, the cooperation between the vertical waist hole 62 and the cross bar 53 enables the belt frame 61 to move only along the radial direction of the rotating ring 5. A telescopic member 54 fixed to the rotating ring 5 is arranged above the cross bar 53. The movable end of the telescopic member 54 is pressed on the upper surface of the belt frame 61. The telescopic member 54 can be a cylinder, an oil cylinder, or a telescopic rod with a built-in spring. The telescopic member 54 is mainly used to push the clamping belt 6 to move, so that the clamping belt 6 can clamp the guide rail workpiece 3 from top to bottom, thereby preventing the guide rail workpiece 3 from jumping and deviating in the radial direction of the rotating ring 5.

[0037] In order to improve the stability of the position of the compression belt 6, the present application also has an annular baffle fixedly sleeved on both ends of the cross bar 53, and the two annular baffles are respectively attached to the two end sides of the belt frame 61, and the diameter of the annular baffle is greater than the inner wall width of the vertical waist hole 62. Figure 5 As shown, the annular baffle is used to position the belt frame 61 to prevent the belt frame 61 from sliding in the length direction of the cross bar 53, thereby improving the stability of the position of the belt frame 61 and the compression belt 6.

[0038] In order to limit the sliding of the receiving slider 7, the present application also has limited sliding grooves 513 at both ends of the surface of the beam 51, and a clamping groove 73 is opened at the lower end of the receiving slider 7. The receiving slider 7 is located in the inner cavity of the limited sliding groove 513, and the clamping groove 73 is clamped on the outer side of the beam 51. Figure 6 and Figure 7 As shown, the limiting slide groove 513 is used to limit the sliding of the receiving slider 7, and the clamping groove 73 is used to clamp the receiving slider 7 on the outside of the beam 51. At this time, the receiving slider 7 can only slide along the length direction of the beam 51 or in the vertical direction.

[0039] In order to prevent the receiving slider 7 from separating from the cross beam 51, the present application also has side grooves 511 on both sides of the cross beam 51, and a convex plate is provided on one side of the linkage plate 71 close to the cross beam 51, and a tooth groove 72 is provided in the middle of the convex plate, and the convex plate is located in the inner cavity of the side groove 511 and adapted thereto. Figure 7 and Figure 8 As shown, the convex plate on the side of the linkage plate 71 can just fit into the inner cavity of the side groove 511. Since the convex plate on the side of the linkage plate 71 can only slide along the length direction of the side groove 511, the receiving slide block 7 cannot slide vertically, and the receiving slide block 7 can only slide in the inner cavity of the limiting slide groove 513 along the length direction of the cross beam 51. In other words, the receiving slide block 7 and the cross beam 51 will not separate from each other. In addition, an avoidance groove 74 adapted to the linkage plate 71 is provided on the inner wall of the card slot 73. Figure 8 and Figure 6 It can be seen that the avoidance groove 74 opened on one receiving slider 7 can allow the linkage plate 71 on the other receiving slider 7 to pass through, so that the end side of the linkage plate 71 can be limited to prevent deformation, thereby ensuring that the tooth groove 72 can always maintain mutual engagement with the center gear 512.

[0040] In order to facilitate the clamping of guide rail workpieces 3 of different sizes, the present application also has thrust springs 514 fixedly installed on the inner walls of the two end limit slides 513 close to each other, and one end of the thrust spring 514 is against the side of the receiving slide block 7, such as Figure 6As shown, the thrust spring 514 is always in a compressed state. The elastic force provided by the thrust spring 514 makes the two receiving sliders 7 always tend to move away from each other. Two inclined guide plates 9 are arranged in the middle of a rotating ring 5, and the two inclined guide plates 9 correspond to the two receiving sliders 7 respectively. When the guide rail workpiece 3 has not been installed, the two receiving sliders 7 remain in a state of moving away from each other. At this time, the distance between one ends of the two inclined guide plates 9 is relatively close. The guide rail workpiece 3 can horizontally slide to squeeze the two inclined guide plates 9 to move closer to each other, thereby driving the two receiving sliders 7 on the same cross beam 51 to move closer to each other until the receiving sliders 7 exactly correspond to the edges of the guide rail workpiece 3. That is to say, when the device clamps guide rail workpieces 3 with different width dimensions, there is no need to manually adjust the position of the receiving sliders 7. Just move the guide rail workpiece 3 and squeeze the two inclined guide plates 9 respectively by the inner walls on both sides of the end of the guide rail workpiece 3.

[0041] In order to facilitate the insertion of the edge of the guide rail workpiece 3 into the inner cavity of the receiving slider 7, the two inclined guide plates 9 of this application are symmetrically distributed in an "eight" shape. An angle steel is fixedly installed on the lower side of the inclined guide plate 9, and the angle steel is fixedly connected to the receiving slider 7. The cross section of the receiving slider 7 is in a "C" shape with an upward opening, which is convenient for positioning the edge of the guide rail workpiece 3. When the edge of the guide rail workpiece 3 passes through the inner cavity of the receiving slider 7, the receiving slider 7 and the guide rail workpiece 3 can remain relatively fixed in the length direction of the cross beam 51. At this time, the guide rail workpiece 3 is pressed down and clamped by the pressing belt 6, and the clamping and positioning of the guide rail workpiece 3 can be realized. The setting of the angle steel is used to keep the inclined guide plate 9 and the receiving slider 7 fixedly connected. Since the upper surface of the angle steel is flush with the bottom of the groove of the receiving slider 7, the guide rail workpiece 3 only needs to be placed on the upper surface of the angle steel to horizontally slide and insert into the inner cavity of the receiving slider 7, and the receiving slider 7 is used to realize the clamping and positioning of the guide rail workpiece 3.

[0042] In order to further improve the stability of the guide rail workpiece 3, this application also has two parallel connecting frames 8 arranged between the two rotating rings 5. The ends of the connecting frames 8 are fixedly connected to the receiving sliders 7 at the corresponding positions. The cross sections of the receiving sliders 7 and the connecting frames 8 are both in a "C" shape with an upward opening, and the bottom of the groove of the receiving slider 7 is flush with the bottom of the groove of the connecting frame 8. As Figure 6 shown, the setting of the connecting frame 8 is used to connect the receiving sliders 7 at the corresponding positions in the inner cavities of the two rotating rings 5. When the guide rail workpiece 3 slides along its own length direction, the four receiving sliders 7 are symmetrically distributed in two groups on both sides of the guide rail workpiece 3, so as to effectively prevent the guide rail workpiece 3 from tilting in the horizontal direction, and further improve the accuracy and stability of the laser cutting head 4 for cutting and processing the guide rail workpiece 3.

[0043] In order to drive the rotating ring 5 to rotate, the present application also has a rolling body movably embedded in the outer wall of the rotating ring 5 to reduce the friction generated between the rotating ring 5 and the protective sleeve 2 when the rotating ring 5 rotates. An annular tooth 52 is arranged on the side of a rotating ring 5, and a motor is installed on the outer side of the protective sleeve 2, and the output end of the motor drives the rotating ring 5 to rotate through the engagement between the gear and the annular tooth 52. When the motor is working, it can drive the rotating ring 5 to rotate. Due to the connecting effect of the connecting frame 8 and the connecting effect of the belt frame 61, the two rotating rings 5 ​​of the device can maintain synchronous rotation. In addition, in order to prevent the connecting frame 8 and the belt frame 61 from being damaged by twisting, the device can also be additionally equipped with a connecting rod to fix the two rotating rings 5 ​​together.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
