Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding, in particular to an inner hole laser cladding device. Background Art

[0002] Laser cladding, also known as laser melting or laser cladding, is a new surface modification technology. It forms a metallurgically bonded filler cladding layer on the surface of the base by adding cladding material to the surface of the base material and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the base material.

[0003] When laser cladding the inner wall of a tubular workpiece, one end of the tubular workpiece is generally clamped by a chuck, and then an inner hole laser head is inserted into the tubular workpiece. The chuck drives the tubular workpiece to rotate, and the movement of the inner hole laser head is coordinated to achieve laser cladding of the inner hole of the tubular workpiece. However, in actual application, some tubular workpieces are relatively long, and existing laser cladding equipment lacks a supporting structure for the tubular workpiece. Only single-end support of the tubular workpiece by the chuck is likely to cause bending of the tubular workpiece, and the middle part of the tubular workpiece will shake, affecting the processing quality and bringing safety hazards. Long-term work may even damage the chuck of the base. Therefore, an inner hole laser cladding equipment is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The inner hole laser cladding equipment of this embodiment includes a clamping base 1, a movable arm 2 and an inner hole laser head 3 installed on the movable arm 2. A movable slide groove 11 is provided on the clamping base 1, and a support block 4 is slidably connected in the movable slide groove 11. A support unit 5 is installed on the support block 4. The support unit 5 includes a support seat 51 installed at the upper end of the support block 4. An adjusting groove 52 is provided on the upper end surface of the support seat 51. Two symmetrically distributed brackets 54 are installed in the adjusting groove 52, and one end of the bracket 54 extends to the outside of the adjusting groove 52.

[0025] like Figure 1-3As shown, the structure of the laser cladding equipment in the utility model is similar to that of the existing laser cladding equipment. The main improvement of the utility model is to improve the stability of the inner hole laser cladding equipment for processing longer tubular workpieces and ensure the cladding quality. When the tubular workpiece needs to be laser clad, the support block 4 is first moved according to the length of the tubular workpiece, and the support block 4 slides with the movable slide groove 11, and the support block 4 drives the support unit 5 to move, and then one end of the tubular workpiece is clamped by the clamping base 1, and the other end of the tubular workpiece is placed on the bracket 54, so as to support both ends of the tubular workpiece. The movable arm 2 is installed on the clamping base 1 and can be moved. At this time, the inner hole laser head 3 is inserted into the tubular workpiece through the movement of the movable arm 2, and the tubular workpiece is driven to rotate by the clamping base 1, so that the inner hole laser head 3 can be clad on the inner wall of the tubular workpiece while moving through the movable arm 2. The overall structure is simple, which is convenient for stably supporting the tubular workpiece, improving the stability of tubular workpiece processing, and ensuring the cladding quality.

[0026] like Figure 4 , 5 As shown, the upper end surface of the support seat 51 is provided with a mounting groove 8, and a cylinder 9 is installed in the mounting groove 8. The support unit 5 also includes a clearance hole 56 provided on the inner bottom surface of the adjustment groove 52. The output end of the cylinder 9 is provided with a clearance hole 56 and is installed with a top plate 57. A push block 58 is fixedly connected to the upper surface of the top plate 57. Two rotating shafts 53 are fixedly connected in the adjustment groove 52. Two brackets 54 are rotatably connected to the outer walls of the two rotating shafts 53 respectively. The push block 58 is abutted against and slidably connected to the lower end outer wall of the bracket 54. According to the size of different tubular workpieces, the top plate 57 can be controlled to rise or fall by the cylinder 9. When the push block 58 rises or falls, the top plate 57 rises or falls, driving the push block 58 to rise or fall. When the push block 58 rises, its two ends slide with the outer wall of the bracket 54, thereby driving the bracket 54 to rotate along the rotating shaft 53 as the axis. The bracket 54 rotates in the adjusting groove 52, so that the upper ends of the two brackets 54 are brought together. When the push block 58 falls, the upper ends of the two brackets 54 rotate outward according to automatic gravity, so that the upper ends of the two brackets 54 are separated, the spacing between the ends of the brackets 54 is controlled, and the lower ends of the two brackets 54 are supported by the push block 58, so that tubular workpieces of different sizes can be stably supported, thereby improving adaptability.

[0027] like Figure 4 As shown, the support unit 5 also includes a middle push rod 59, the lower end of which is fixedly connected to the upper surface of the push block 58, and one end of the middle push rod 59 extends outside the adjustment slot 52; when the push block 58 rises or falls, the middle push rod 59 is driven to rise or fall, and the middle push rod 59 can cooperate with the two brackets 54 to support the tubular workpiece, thereby improving the stability of the support and increasing the size range of the supported tubular workpiece.

[0028] like Figure 3 , 4As shown, the middle push rod 59 is rotatably connected to the second rollers 510 on both sides outside the adjusting groove 52, and the bracket 54 is rotatably connected to the first rollers 55 on both sides outside the adjusting groove 52; the bracket 54 and the middle push rod 59 respectively support the tubular workpiece stably through the first roller 55 and the second roller 510, and when the clamping base 1 drives the tubular workpiece to rotate, it drives the first roller 55 and the second roller 510 to rotate, thereby reducing the wear on the tubular workpiece and adapting to its inner hole cladding operation.

[0029] like Figure 4 As shown, the support unit 5 also includes two limit bars 511, both ends of which are fixedly connected to the inner wall of the adjustment groove 52, and the middle push rod 59 is slidably connected between the two limit bars 511; the middle push rod 59 is supported by the two limit bars 511 when moving up and down, and the two limit bars 511 limit the middle push rod 59 to improve the strength of the middle push rod 59.

[0030] like Figure 3-5 As shown, the support seat 51 is installed with the support block 4 by bolts, the outer wall of the output end of the cylinder 9 is fixedly connected with the mounting plate 10, the mounting plate 10 is fixed with the top plate 57 by bolts, and the output end of the cylinder 9 is installed with the top plate 57 through the mounting plate 10; the cylinder 9 is installed with the top plate 57 through the mounting plate 10, and the support seat 51 is installed with the support block 4 by bolts, and the support seat 51 is detachable, which is convenient for cleaning, maintenance, replacement and other operations, thereby improving adaptability and practicality.

[0031] like Figure 2 As shown, a threaded rod 6 is rotatably connected in the movable slide groove 11, and a motor 7 is installed on one side of the clamping base 1. The output shaft of the motor 7 passes through the movable slide groove 11 and is fixedly connected to one end of the threaded rod 6. The threaded rod 6 passes through the support block 4 and is threadedly connected thereto; when the motor 7 is started, the motor 7 can drive the threaded rod 6 to rotate, and the threaded rod 6 drives the support block 4 to move in the adjustment groove 52, thereby adjusting the position of the support unit 5 without manual adjustment, which is convenient to use.

[0032] Among them, the above-mentioned motor 7 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The motor 7 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0033] The implementation steps in this embodiment are as follows: when it is necessary to perform laser cladding on a tubular workpiece, one end of the tubular workpiece is clamped by the clamping base 1, and the motor 7 is controlled to start. The motor 7 can drive the threaded rod 6 to rotate, and the threaded rod 6 drives the support block 4 to move in the adjustment groove 52, thereby adjusting the position of the support unit 5, so that the support unit 5 moves to the end of the tubular workpiece that is not supported. At this time, the top plate 57 can be controlled to rise by the cylinder 9, and the rise of the top plate 57 drives the push block 58 to rise. The push block 58 rises and its two ends slide with the outer wall of the bracket 54, thereby driving the bracket 54 to rotate along the rotating shaft 53 as the axis, and the bracket 54 rotates in the adjustment groove 52, so that the upper ends of the two brackets 54 are close to each other, and the push block 58 drives the middle push rod 59 to rise until the end of the bracket 54 The first roller 55 and the second roller 510 at the end of the middle push rod 59 can be fitted with the outer wall of the tubular workpiece, and the end of the tubular workpiece away from the clamping base 1 is supported by the first roller 55 and the second roller 510, thereby achieving support for both ends of the tubular workpiece. At this time, the inner hole laser head 3 is inserted into the tubular workpiece by moving the movable arm 2, and the tubular workpiece is driven to rotate by the clamping base 1. The tubular workpiece drives the first roller 55 and the second roller 510 to rotate, thereby reducing the wear on the tubular workpiece, and the inner hole laser head 3 can be moved by the movable arm 2 while cladding the inner wall of the tubular workpiece. The overall structure is simple, which is convenient for stably supporting the tubular workpiece, improving the stability of tubular workpiece processing, and ensuring the cladding quality.
