DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] like Figure 1-4 As shown, this embodiment proposes a device for detecting the anti-cracking performance of fire retardant coatings, including a base 1, the base 1 is connected to a support shaft by rotation, the support shaft is fixedly connected to a rotating seat 3, the rotating seat 3 is slidably connected to a V-shaped seat 8, the V-shaped seat 8 is connected to a movable seat 7, the movable seat 7 is slidably connected to a left clamping plate 22, and the V-shaped seat 8 is slidably connected to a right clamping plate 23.

[0030] The rotating seat 3 is fixedly connected with a guide rail 4 arranged in the horizontal direction, and the V-shaped seat 8 is slidably connected to the guide rail 4. The guide rail 4 serves as a limit and guide for the movement of the V-shaped seat 8, so that the V-shaped seat 8 can only slide along the length direction of the guide rail 4.

[0031] The base 1 is slidably connected to a lifting plate 18 that moves in a vertical direction, and the lifting plate 18 is slidably connected to a spray gun 9 that moves in a horizontal direction. When the right clamping plate 23 moves, it can drive the spray gun 9 to move in the same direction and drive the V-shaped seat 8 to move in the opposite direction.

[0032] Among them, when the left clamping plate 22 moves horizontally, the left clamping plate 22 can drive the workpiece 26 to move to the right. The workpiece 26 first contacts the right clamping plate 23, which can drive the right clamping plate 23 to move to the right first. The movement direction of the spray gun 9 is the same as the movement direction of the right clamping plate 23. At the same time, the right clamping plate 23 drives the V-shaped seat 8 to move toward the direction close to the workpiece 26. The left clamping plate 22 and the V-shaped seat 8 cooperate with each other to achieve the clamping of the workpiece 26.

[0033] Through the above-mentioned setting, the distance between the spray gun 9 and the workpiece 26 can be adaptively adjusted according to the size of the workpiece. The workpiece 26 always maintains a suitable distance from the spray gun 9. There is no need to repeatedly adjust the position of the spray gun 9, which effectively simplifies the overall operation and facilitates the subsequent anti-cracking performance detection.

[0034] The spray gun 9 can be specifically a flame spray gun that can spray flames. It regulates the pressure and flow of the fuel gas and sprays it out of the gun muzzle and ignites it to form a high-temperature columnar flame to detect the anti-cracking performance of the fire retardant coating on the surface of the workpiece 26. In addition, the spray gun 9 can also be replaced by other heating mechanisms. For example, the spray gun 9 can be replaced by a hot air blower, which can spray dry hot air to achieve the detection of the anti-cracking performance of the surface of the workpiece 26.

[0035] The base 1 is fixedly connected to a motor 20, which can drive the rotating seat 3 to rotate through a transmission assembly 2. The transmission assembly 2 includes an output shaft connected to the motor 20, the output shaft is fixedly sleeved on a first gear, and the support shaft is fixedly sleeved with a second gear. The first gear and the second gear are meshed, and the motor 20 can drive the rotating seat 3 to rotate.

[0036] The base 1 is also rotatably connected to a first rotating shaft, which is arranged horizontally. The first rotating shaft is eccentrically connected to a rotating wheel 17. The lifting plate 18 has a movable groove, and the rotating wheel 17 is movably arranged in the movable groove. The motor 20 can drive the first rotating shaft to rotate through the bevel gear set 19.

[0037] The bevel gear set 19 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly sleeved on the output shaft, and the second bevel gear is fixedly sleeved on the first rotating shaft. The first bevel gear and the second bevel gear are meshed with each other. The motor 20 can drive the first rotating shaft to rotate, and then drive the eccentrically connected wheel 17 to rotate.

[0038] The width of the movable groove is suitable enough, and the rotating wheel 17 can move freely in the movable groove. When the rotating wheel 17 rotates upward, it can drive the lifting plate 18 to move upward. When the rotating wheel 17 rotates downward, the rotating wheel 17 contacts the bottom surface of the movable groove and can drive the lifting plate 18 to move downward. The rotation of the rotating wheel 17 can drive the lifting plate 18 to reciprocate in the vertical direction, thereby driving the spray gun 9 to reciprocate in the vertical direction.

[0039] The V-shaped seat 8 is provided with a T-shaped slot 25 arranged in a vertical direction, and the movable seat 7 is fixedly connected with a T-shaped block, and the T-shaped block and the T-shaped slot 25 are slidably connected. The T-shaped slot 25 is a structure with an open upper end and a closed lower end. The movable seat 7 can move upward to move the T-shaped block upward out of the upper end opening of the T-shaped slot 25. The movable seat 7 of a suitable shape can be replaced according to the size or shape of the workpiece 26, thereby facilitating the clamping of the workpiece 26.

[0040] The movable seat 7 is rotatably connected to the second rotating shaft, and the second rotating shaft is fixedly connected to the eccentric wheel 21, which is arranged on one side of the left clamping plate 22.

The second rotating shaft is fixedly sleeved with a ratchet wheel matched with the latch 5, and one end of the latch 5 passes through the movable seat 7, and the second rotating shaft is fixedly connected to the hand wheel 6.

[0041] The left clamping plate 22 is also sleeved with a fifth spring, the left end of the fifth spring is connected to the left clamping plate 22, and the end of the fifth spring is connected to the movable seat 7. The setting of the fifth spring facilitates the resetting of the left clamping plate 22 after the clamping work of the workpiece 26 is completed.

[0042] In the initial state, under the action of the fifth spring, the left clamping plate 22 and the right clamping plate 23 can be driven to leave a sufficient distance. When the eccentric wheel 21 rotates, the left clamping plate 22 can be driven to move toward the workpiece 26, at which time the fifth spring is compressed.

[0043] When the eccentric wheel 21 rotates and the left clamping plate 22 moves towards the workpiece 26, the second rotating shaft can drive the ratchet to rotate, and the ratchet drives the latch 5 to slide along the movable seat 7. Under the action of the latch 5, the second rotating shaft can be prevented from reversing, so that the workpiece 7 can be clamped. When it is necessary to release the limit, it is only necessary to pull the latch 5 outward. At this time, the latch 5 no longer limits the ratchet, and the clamping can be released.

[0044] The lifting plate 18 is also slidably connected to an adjustment seat 13, and the spray gun 9 is fixedly connected to the adjustment seat 13. The adjustment seat 13 moves horizontally, which can drive the spray gun 9 to move horizontally, thereby adjusting the distance between the spray gun 9 and the workpiece 26.

[0045] The adjustment seat 13 is fixedly connected with a first ratchet, and the lifting plate 18 is slidably connected with a restraining pin 14 matched with the first ratchet. The restraining pin 14 is connected to the lifting plate 18 through a third spring.

[0046] When the adjustment seat 13 moves to the right, it can drive the spray gun 9 to move away from the workpiece 26. At this time, the first ratchet can drive the restraining pin 14 and the lifting plate 18 to slide relative to each other. Under the action of the restraining pin 14, the adjustment seat 13 can be prevented from moving to the left. Only after the restraining pin 14 is pressed downward, the adjustment seat 13 can move to the left.

[0047] The right clamping plate 23 is fixedly connected to the upper rack 10, the V-shaped seat 8 is fixedly connected to the lower rack 15, the rotating seat 3 is rotatably connected to the gear 11, and the upper and lower ends of the gear 11 are respectively engaged with the upper rack 10 and the lower rack 15; the upper rack 10 is connected to the push rod 12, and the push rod 12 is arranged on one side of the adjustment seat 3.

[0048] The gear 11 can realize the reversing operation, the workpiece 26 can drive the right clamping plate 23 to move to the right, and the gear 11 can drive the V-shaped seat 8 to move to the left, the left clamping plate 22 and the V-shaped seat 8 can clamp the workpiece 26, and the push rod 12 can drive the adjustment seat 3 to move horizontally, so that the distance between the spray gun 9 and the workpiece 26 is adapted to the size of the workpiece 26.

[0049] The push rod 12 can be rotatably connected to the upper rack 10, and the push rod 12 can be threadedly connected to the adjustment seat 13. By rotating the push rod 12, the distance between the adjustment seat 13 and the workpiece 26 can be adjusted. The push rod 12 can be freely rotated according to actual detection needs. At this time, when the push rod 12 moves, it can drive the spray gun 9 to move at the same time.

[0050] The lower rack 15 is fixedly connected with the second ratchet, and the lower rack 15 is connected to the rotating seat 3 through the first spring 16. The rotating seat 3 is slidably connected with a pawl 24 that matches the second ratchet, and the pawl 24 is connected to the rotating seat 3 through the fourth spring.

[0051] The first spring 16 is used for resetting the lower rack 15. The right end of the first spring 16 is connected to the lower rack 15, and the left end of the first spring 16 is connected to the rotating seat 3. Under the action of the first spring 16, the right clamping plate 23 is located on the left side of the V-shaped seat 8. Because when the left clamping plate 22 drives the workpiece 26 to move to the right, the workpiece 26 first contacts the right clamping plate 23.

[0052] The specific working process is as follows: place the workpiece 26 between the left clamping plate 22 and the right clamping plate 23, rotate the eccentric wheel 21 by the hand wheel 6, the eccentric wheel 21 drives the left clamping plate 22 to move towards the direction close to the workpiece 26, the workpiece 26 first contacts the right clamping plate 26, and drives the right clamping plate 26 to move to the right. During this process, the eccentric wheel 21 drives the ratchet to rotate, and the ratchet drives the pin 5 to slide relative to the movable seat 7. Under the action of the pin 5, the eccentric wheel 21 can be prevented from reversing.

[0053] When the right clamping plate 26 moves to the right, the gear 11 can drive the V-shaped seat 8 to move to the left, and the V-shaped seat 8 and the left clamping plate 22 cooperate with each other to clamp the workpiece 26. At the same time, the right clamping plate 26 drives the adjustment seat 13 to move to the right, and the adjustment seat 13 drives the spray gun 9 to move to the right, so that a suitable distance is always maintained between the spray gun 9 and the workpiece 26.
