Description

Technical Field

[0001] This application relates to the field of cladding head technology, and more specifically, to a laser cladding head for the inner hole of a mold. Background Technology

[0002] Laser cladding technology is increasingly widely used. For example, patent CN221626386U describes a laser cladding head that uses a fastening head, a fixing frame, and a fastening head structure. The fastening head connects and is fixed to a connecting block. Its internal slot structure limits and fixes a locking plate, which is then threadedly connected to the connecting plate, thus connecting the mounting frame and the laser cladding head. Similar to commonly used laser cladding heads, replacing them primarily involves using multiple sets of bolts for fixing and disassembly, which is not only slow but also results in relatively high downtime costs. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a laser cladding head for mold inner holes, which aims to improve the problem of slow speed and relatively high downtime costs when changing laser cladding heads.

[0004] This application provides a laser cladding head for mold inner holes, including a laser cladding head body, a base plate, a lifting assembly, and a clamping and fixing assembly.

[0005] The lifting assembly is installed on one side of the seat plate to drive the clamping and fixing assembly to move and adjust in the vertical direction; The clamping and fixing assembly includes a lower clamp, an upper clamp, an elastic support, and an elastic positioning member. The lower clamp is connected to the lifting assembly, and the elastic support connects the lower clamp and the upper clamp. The lower clamp and the upper clamp are both provided with the same U-shaped groove. The elastic positioning members are symmetrically arranged on both sides of the lower clamp and the upper clamp, and are elastically limited and engaged with the outside of the laser cladding head body column inside the U-shaped groove of the lower clamp and the upper clamp.

[0006] Preferably, the lifting assembly includes a support, a lead screw, a movable seat, and a motor. Two sets of the supports are fixed to one side of the seat plate. The lead screw is rotatably disposed between the two supports. The motor is installed on the side of the seat plate to drive the lead screw to rotate. The movable seat is slidably disposed on the side of the seat plate and is screwed to the lead screw.

[0007] Preferably, the lifting assembly further includes a guide rail, which connects the movable seat and the seat plate.

[0008] Preferably, the elastic support includes a sleeve, a first spring, and a sleeve rod. The bottom end of the sleeve is fixed to the lower clamp, the top end of the sleeve rod is fixed to the upper clamp, and the bottom end of the sleeve rod is movably inserted inside the sleeve. The first spring is sleeved on the outside of the sleeve and the sleeve rod.

[0009] Preferably, the sleeve side is provided with symmetrical guide grooves, and the outer bottom end of the sleeve rod is fixed with a limiting block that slides with the guide grooves.

[0010] Preferably, the elastic positioning component includes a side frame, a positioning block, a second spring, and a limiting rod. One end of the limiting rod is fixedly disposed with the positioning block, and the other end of the limiting rod slides through the side frame. The second spring is sleeved on the outside of the limiting rod. The inner sides of the lower clamp and the upper clamp are provided with slots that cooperate with the sliding of the positioning block.

[0011] Preferably, the inner side of the end of the positioning block is provided with a positioning groove that mates with the outer wall of the laser cladding head body, and the inner side of the end of the positioning block is provided with a guide surface.

[0012] Beneficial Effects: This application provides a laser cladding head for mold inner holes. As the laser cladding head body is pulled outwards, the elastic positioning components limiting the lower and upper clamps are compressed, allowing for rapid removal of the laser cladding head body. The new laser cladding head body's column side is horizontally inserted into the U-shaped grooves of the lower and upper clamps. The elastic positioning components protruding from the inner sides of the lower and upper clamps are elastically compressed. When the laser cladding head body is fully inserted, the elastic positioning components elastically reset and limit the laser cladding head body's column sidewall, clamping and fixing the laser cladding head body. Compared to traditional bolt-based assembly and disassembly methods, this laser cladding head for mold inner holes offers faster assembly and disassembly speeds, reducing downtime costs associated with replacing laser cladding heads.

[0016] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0017] Please see Figures 1-4 This application provides a laser cladding head for the inner hole of a mold, including a laser cladding head body 1, a base plate 2, a lifting assembly 3, and a clamping and fixing assembly 4.

[0018] The lifting assembly 3 is installed on one side of the base plate 2 to drive the clamping and fixing assembly 4 to move and adjust in the vertical direction. The clamping and fixing assembly 4 includes a lower clamp 41, an upper clamp 42, an elastic support 43, and an elastic positioning member 44. The lower clamp 41 is connected to the lifting assembly 3, and the elastic support 43 connects the lower clamp 41 and the upper clamp 42. The lower clamp 41 and the upper clamp 42 are both provided with the same U-shaped groove. The elastic positioning members 44 are symmetrically arranged on both sides of the lower clamp 41 and the upper clamp 42, and are elastically limited and engaged with the outside of the column rod of the laser cladding head body 1 inside the U-shaped groove of the lower clamp 41 and the upper clamp 42.

[0019] When it is necessary to replace the laser cladding head body 1, simply pull the laser cladding head body 1 horizontally along the U-shaped groove of the lower clamp 41 and the upper clamp 42. As the laser cladding head body 1 is pulled outwards, the elastic positioning element 44, which limits movement on the inner side of the lower clamp 41 and the upper clamp 42, will be compressed, allowing the laser cladding head body 1 to be quickly pulled out. Insert the column side of the new laser cladding head body 1 horizontally into the U-shaped groove of the lower clamp 41 and the upper clamp 42. The elastic positioning element 44, protruding from the inner side of the lower clamp 41 and the upper clamp 42, will be elastically compressed. When the laser cladding head body 1 is fully inserted, the elastic positioning element 44 elastically resets and limits movement on the column side wall of the laser cladding head body 1, clamping and fixing the laser cladding head body 1. Compared to the traditional bolt-on method, this mold inner hole laser cladding head has a faster disassembly and assembly speed, reducing downtime costs associated with replacing the laser cladding head. The lifting component 3 can adjust the vertical position of the laser cladding head body 1 to adapt to the cladding processing of different mold inner holes. The elastic support of the elastic support member 43 allows the lower clamp 41 to abut against the bottom protrusion of the column and the upper clamp 42 to abut against the top protrusion of the column when the lower clamp 41 and the upper clamp 42 are engaged with the column outside the laser cladding head body 1. This allows the lower clamp 41, the upper clamp 42, the elastic support member 43 and the elastic positioning member 44 to fix the laser cladding head body 1 more stably.

[0020] In the above specific embodiment, the lifting assembly 3 includes a support 31, a lead screw 32, a movable seat 33, and a motor 34. Two sets of supports 31 are fixed to one side of the base plate 2. The lead screw 32 is rotatably disposed between the two supports 31. The motor 34 is mounted on the side of the base plate 2 to drive the lead screw 32 to rotate. The movable seat 33 is slidably disposed on the side of the base plate 2 and screwed to the lead screw 32. The output shaft end of the motor 34 is connected to the top end of the lead screw 32 through a coupling. The output shaft end of the motor 34 drives the movable seat 33 to slide and adjust in the vertical direction, that is, drives the clamping and fixing assembly 4 and the laser cladding head body 1 to move and adjust their positions in the vertical direction.

[0021] Furthermore, the lifting assembly 3 also includes a guide rail 35, which connects the movable seat 33 and the seat plate 2. The guide rail 35 includes a guide rail and a guide seat, which improves the stability of the clamping and fixing assembly 4 when it moves in the vertical direction.

[0022] In its specific configuration, the elastic support 43 includes a sleeve 432, a first spring 431, and a rod 433. The bottom end of the sleeve 432 is fixed to the lower clamp 41, and the top end of the rod 433 is fixed to the upper clamp 42. The bottom end of the rod 433 is movably inserted inside the sleeve 432, and the first spring 431 is sleeved on the outside of the sleeve 432 and the rod 433. The sleeve 432 has symmetrical guide grooves on its side, and a limiting block 434 that slides with the guide grooves is fixed to the bottom outer side of the rod 433. The cooperation of the first spring 431, sleeve 432, and rod 433 in the elastic support 43 allows the lower clamp 41 and upper clamp 42 to clamp the outer edges of both ends of the rod of the laser cladding head body 1 under the elastic support of the first spring 431. The sleeve 432, the sleeve rod 433, the limiting block 434 and the guide groove are used to limit the first spring 431 and connect the lower clamp 41 and the upper clamp 42.

[0023] Specifically, the elastic positioning component 44 includes a side frame 441, a positioning block 442, a second spring 443, and a limiting rod 444. One end of the limiting rod 444 is fixedly mounted to the positioning block 442, and the other end of the limiting rod 444 slides through the side frame 441. The second spring 443 is sleeved on the outside of the limiting rod 444. The inner sides of the lower clamp 41 and the upper clamp 42 are both provided with slots 45 that slide with the positioning block 442. The inner side of the end of the positioning block 442 is provided with a positioning groove 445 that mates with the outer wall of the laser cladding head body 1, and the inner side of the end of the positioning block 442 is provided with a guide surface 446. Under the elastic support of the second spring 443, the positioning groove 445 on the inner side of the positioning block 442 is used to limit and fix the outer wall of the column of the laser cladding head body 1, and the guide surface 446 is provided to guide the smooth installation of the laser cladding head body 1.

[0024] It should be noted that the specific models and specifications of the motor 34 and the laser cladding head body 1 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here. The power supply and principle of the motor 34 and the laser cladding head body 1 are clear to those skilled in the art, and will not be described in detail here.

[0025] The working principle of this laser cladding head for mold inner holes is as follows: During use, the laser cladding head body 1 can be quickly pulled out. The new laser cladding head body 1 is horizontally inserted into the U-shaped grooves of the lower clamp 41 and upper clamp 42 on the side of the column. The elastic positioning element 44 protruding from the inner side of the lower clamp 41 and upper clamp 42 is elastically compressed. When the laser cladding head body 1 is fully inserted, the elastic positioning element 44 elastically resets and limits the side wall of the column of the laser cladding head body 1, clamping and fixing the laser cladding head body 1. Compared with the traditional bolt disassembly and assembly method, this laser cladding head for mold inner holes has a faster disassembly and assembly speed, reducing downtime costs associated with replacing the laser cladding head. The lifting component 3 can adjust the vertical position height of the laser cladding head body 1 to adapt to different mold inner hole cladding processes.
