Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laser welding, and in particular relates to an adjustment mechanism for a laser welding machine. Background Art
[0002] Before each processing or experiment of laser equipment, the first step is to adjust the focus. Only by finding the focal plane can other process parameters be determined, such as defocus, power, speed, etc. Because the laser beam is in the shape of an hourglass under the action of the focusing mirror, the energy is most concentrated and strongest at the waist position, and the processing efficiency is the best.
[0003] However, the focusing process of existing laser equipment relies heavily on experience, resulting in uneven processing quality when different people operate the same equipment.
[0004] Based on this, it is necessary to design a walking device that can automatically adjust the focus. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides a laser welding machine adjustment mechanism, and the specific technical solution is as follows:
[0006] A laser welding machine adjustment mechanism includes a traveling mechanism and an adjustment mechanism, wherein the adjustment mechanism is located on one side of the traveling mechanism and is transmission-connected to the traveling mechanism, wherein the adjustment mechanism includes a closed shell, wherein a self-locking motor is provided on the top surface of the closed shell, wherein a screw rod 1 is provided inside the closed shell, wherein the screw rod 1 is transmission-connected to the self-locking motor, wherein the screw rod 1 is threadedly connected to a screw rod sleeve, wherein one end of the screw rod sleeve is slidably matched with a slide rod 1 arranged parallel to the screw rod 1, wherein the screw rod sleeve is connected to the top of a laser emitting assembly, wherein the bottom of the laser emitting assembly passes through the closed shell, wherein a rangefinder is provided on the other side of the closed shell, wherein a signal output end of the rangefinder is signal-connected to a signal input end of the self-locking motor.
[0007] As an improvement of the above technical solution, when the screw sleeve moves to the uppermost position along screw one, the bottom of the laser emitting assembly is located outside the closed shell.
[0008] As an improvement of the above technical solution, the walking mechanism includes symmetrically arranged mounting plates, with a movable block between the mounting plates, the movable block is passed through two sliding rods 2 and one screw rod 2 distributed in a triangular shape, and the two ends of the sliding rod 2 and the screw rod 2 are respectively connected to the corresponding mounting plates, and a driving motor connected to the screw rod 2 for transmission is installed on one of the mounting plates.
[0009] As an improvement of the above technical solution, an accordion-type protective cover is provided between the movable block and the corresponding sides of the mounting plate, and the second sliding rod and the second screw rod extending from both sides of the movable block are both located in the corresponding accordion-type protective cover.
[0010] As an improvement of the above technical solution, the closed shell is fixed to one side of the movable block.
[0011] As an improvement of the above technical solution, the sliding rod 2 is arranged above the screw rod 2, the two sliding rods 2 are parallel and located in the same horizontal plane, and the two sliding rods 2 and the screw rod 2 are distributed in an equilateral triangle.
[0012] Beneficial effects of the utility model:
[0013] 1. The self-locking motor drives the lead screw to rotate, forcing the lead screw sleeve to move to the top or bottom. Then the distance meter detects the distance to the workpiece. The value minus the focal length is the distance that the laser emission component needs to adjust. Negative values require upward movement, and positive values require downward movement. The moving distance is completed by the number of turns driven by the self-locking motor. The upward or downward movement is achieved by the forward and reverse rotation of the self-locking motor. After the distance adjustment is completed, the position of the self-locking motor is locked. In this way, only one adjustment is required when processing the same batch of products, and the focusing is fast and convenient.
[0014] 2. The sliding rod is parallel and arranged above the second screw rod, which can support the movement of the accordion-type protective cover and prevent the accordion-type protective cover from falling down and affecting the movement of the movable block after the accordion-type protective cover is stretched too long.

DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0020] like Figure 1-3The utility model provides a technical solution: a laser welding machine adjustment mechanism, including a walking mechanism 100 and an adjustment mechanism 200, the adjustment mechanism 200 is located at one side of the walking mechanism 100 and is transmission-connected to the walking mechanism 100, the adjustment mechanism 200 includes a closed shell 210, the top surface of the closed shell 210 is provided with a self-locking motor 220, the closed shell 210 is provided with a screw rod 230, the screw rod 230 is transmission-connected to the self-locking motor 220, the screw rod 230 is threadedly connected with a screw rod sleeve 240, one end of the screw rod sleeve 240 is slidably matched with a slide rod 250 arranged parallel to the screw rod 230, the screw rod sleeve 240 is connected to the top of a laser emitting assembly 300, the bottom of the laser emitting assembly 300 passes through the closed shell 210, the other side of the closed shell 210 is provided with a rangefinder 260, and the signal output end of the rangefinder 260 is signal-connected to the signal input end of the self-locking motor 220.
[0021] The existing welding machine focusing structure is appropriately changed. Since the focal length is a fixed value, the zeroing operation is first performed each time the focus is adjusted, that is, the self-locking motor 220 drives the screw rod 230 to rotate, thereby forcing the screw rod sleeve 240 to move to the top or bottom. Then the rangefinder 260 detects the distance value from the workpiece. The value minus the focal length is the distance that the laser emitting component 300 needs to adjust. A negative value requires an upward move, and a positive value requires a downward move. The moving distance is completed by the number of turns driven by the self-locking motor 220. The upward or downward move is achieved by the forward and reverse rotation of the self-locking motor 220. After the distance adjustment is completed, the position of the self-locking motor 220 is locked. In this way, only one adjustment is required when processing the same batch of products, and the focusing is fast and convenient.
[0022] Specifically, when the screw sleeve 240 moves to the top along the screw 1 230, the bottom of the laser emitting assembly 300 is located outside the closed housing 210. It is ensured that no matter where the screw sleeve 240 is, it will not affect the operation of the laser emitting assembly 300.
[0023] Specifically, the walking mechanism 100 includes symmetrically arranged mounting plates 110, with a movable block 120 between the mounting plates 110, and the movable block 120 is penetrated by two sliding rods 130 and a screw rod 140 distributed in a triangle, and the two ends of the sliding rod 130 and the screw rod 140 are respectively connected to the corresponding mounting plates 110, and a driving motor 150 connected to the screw rod 140 is installed on one of the mounting plates 110. The sliding rod 130 and the screw rod 140 are connected to the corresponding mounting plates 110 to form a whole, ensuring that the movable block 120 can slide on the sliding rod 130 and the screw rod 140, and the driving motor 150 drives the screw rod 140 to rotate, so as to realize the stable movement of the movable block 120 and drive the adjustment mechanism 200 to move.
[0024] Specifically, an accordion-type protective cover 160 is provided between the movable block 120 and the corresponding sides of the mounting plate 110, and the second slide bar 130 and the second screw rod 140 extending from both sides of the movable block 120 are both located in the corresponding accordion-type protective cover 160. The accordion-type protective cover 160 can achieve sealing without affecting the movable block 120, so as to prevent dust and cutting from corroding the second slide bar 130 and the second screw rod 140, thereby affecting the stable movement of the movable block 120.
[0025] Specifically, the sealed housing 210 is fixed to one side of the movable block 120. Since the sealed housing 210 is relatively large, and the bottom ends of the laser emitting assembly 300 and the rangefinder 260 both extend out of the bottom surface of the sealed housing 210, it is most preferred to fix the sealed housing 210 to one side of the movable block 120.
[0026] Specifically, the second slide bar 130 is arranged above the second screw rod 140, the two second slide bars 130 are parallel and located on the same horizontal plane, and the two second slide bars 130 and the second screw rod 140 are distributed in an equilateral triangle. The slide bars are parallel and arranged above the second screw rod 140, which can support the movement of the accordion-type protective cover 160, and prevent the accordion-type protective cover 160 from falling down after being stretched too long, which affects the movement of the movable block 120.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
