[0017] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 , Figure 2 As shown, a galvanized layer adhesion performance test device includes a base 1, a slide seat 2, a knock hammer 3, a support frame 4, a support rod 5 and a fixing mechanism 6.

[0019] like Figure 1 , Figure 2As shown, the base 1 is horizontally arranged on the table, and a level 11 is arranged on the upper end surface of the base 1, so as to conveniently and intuitively judge the levelness of the base 1. The four corners of the base 1 are threadedly connected with a leveling seat 12, which is used to quickly adjust the levelness of the base 1 to meet the test requirements.

[0020] like Figure 1 , Figure 2 As shown, the slide 2 is horizontally slidably connected to the base 1, and a screw 13 is horizontally rotatably connected to the base 1. The screw 13 is threadedly connected to the slide 2 to adjust the position of the slide 2 when the screw 13 rotates. The hammer handle at the lower end of the percussion hammer 3 is rotatably connected to the slide 2 to adjust the landing point of the hammer head of the percussion hammer 3 when the slide 2 slides.

[0021] like Figure 2 , Figure 3 As shown, the support frame 4 is vertically arranged at the rear end of the slide 2, and the support rod 5 includes a seat plate 51, a supporting rod 52 and a rotating rod 53. The seat plate 51 is horizontally slidably connected to the support frame 4, and the supporting rod 52 is horizontally arranged on the seat plate 51, and is used to resist the hammer head of the knocking hammer 3, so that the knocking hammer 3 is in a vertical state, thereby ensuring the working stability of the knocking hammer 3. The rotating rod 53 is horizontally rotatably connected to the support frame 4, and is threadedly connected to the seat plate 51. The outer walls of the screw rod 13 and the rotating rod 53 are both provided with sprockets 54, and a chain 55 is wound between the pair of sprockets 54.

[0022] like Figure 2 , Figure 4 As shown, the fixing mechanism 6 is disposed at the front end of the slide 2 and is used to fix the test piece. The fixing mechanism 6 includes a pair of fixing plates 61 , a slide block 62 and a bidirectional lead screw 63 .

[0023] like Figure 2 , Figure 4 As shown, the fixing plates 61 are arranged side by side on the base 1, and the inner side of the fixing plates 61 is provided with a step-shaped slot 64, and the slot 64 is provided for the two sides of the test pieces of different thicknesses to be embedded. The slider 62 is arranged on the lower end surface of the fixing plate 61 and is laterally slidably connected to the base 1, and the bidirectional lead screw 63 is horizontally rotatably connected to the base 1 and is threadedly connected to a pair of sliders 62.

[0024] When it is necessary to test the galvanized steel plate specimen, the galvanized steel plate specimen is placed on the base 1 and located between a pair of fixed plates 61. The bidirectional lead screw 63 is then controlled to rotate, and the bidirectional lead screw 63 is used to drive the pair of fixed plates 61 closer to each other to achieve centering and clamping of the specimen. At the same time, both sides of the specimen are embedded in the slots 64 on the fixed plates 61 to achieve clamping of the specimen.

[0025] Then, the hammer 3 is gently controlled to flip so that the hammer head of the hammer 3 contacts the surface of the test piece, and then the screw 13 is controlled to rotate, and the screw 13 is used to drive the slide 2 to slide, and the position of the hammer 3 is adjusted to complete the adjustment of the landing point of the hammer 3.

[0026] At the same time, during the rotation of the screw 13, with the cooperation of the sprocket 54 and the chain 55, the rotating rod 53 is driven to rotate synchronously, and the rotating rod 53 drives the seat plate 51 and the supporting rod 52 to slide synchronously, so that no matter how the sliding seat 2 slides, the knocking hammer 3 can contact the supporting rod 52 after flipping, and the knocking hammer 3 can always be in a state perpendicular to the base 1.

[0027] Then the hammer 3 is controlled to rotate upward until it turns to a vertical state, and then the hammer 3 is controlled to move forward so that the hammer 3 falls freely and hits the specimen to test the specimen. Then the position of the slide 2 can be adjusted again to change the different landing positions of the hammer 3. Therefore, when testing the same specimen, the different landing positions of the hammer 3 can be quickly located to meet the needs of rapid testing of different positions of the specimen, thereby improving test efficiency and test accuracy.

[0028] like Figure 3 As shown, a gantry 7 is provided at the front end of the seat plate 51, and a push rod 71 for pushing the striking hammer 3 is horizontally slidably connected to the gantry 7, and a spring 72 for controlling the push rod 71 to slide outward is provided between the gantry 7 and the push rod 71.

[0029] like Figure 3 As shown, a plug rod 73 is vertically slidably connected to the gantry 7, a plug hole 74 for plugging the plug rod 73 is provided on the push rod 71, and a tension spring 75 for controlling the plug rod 73 to slide downward is provided between the gantry 7 and the plug rod 73.

[0030] Before flipping the hammer 3 upward to a vertical state, the push rod 71 is controlled to slide inward and compress the spring 72. When the lower end of the insertion rod 73 is aligned with the insertion hole 74, the insertion rod 73 is inserted into the insertion hole 74 on the push rod 71 under the action of the tension spring 75, thereby fixing the push rod 71.

[0031] When it is necessary to control the hammer 3 to flip forward, pull the rod 73 to slide upward until the rod 73 is driven out of the socket 74. Under the thrust of the spring 72, the push rod 71 automatically slides outward and automatically pushes the hammer 3 to flip, thereby ensuring that the hammer 3 can flip at the same speed and force in each test, thereby ensuring measurement accuracy.

[0032] like Figure 1 , Figure 5As shown, a positioning tube 8 is vertically arranged on the base 1, and the positioning tube 8 is located between the fixing mechanism 6 and the sliding seat 2. A positioning rod 81 is vertically slidably connected in the positioning tube 8, and an elastic member 82 for driving the positioning rod 81 to slide upward is arranged in the positioning tube 8. The positioning rod 81 is used to slide upward and support the knocking hammer 3 after the knocking hammer 3 hits it.

[0033] like Figure 5 As shown, a locking member 9 for fixing the positioning rod 81 is disposed in the positioning tube 8 , and the locking member 9 includes a locking rod 91 , a locking plate 92 and a locking column 93 .

[0034] like Figure 5 As shown, the lower end of the locking rod 91 is rotatably connected to the lower end of the positioning rod 81, the locking plate 92 is arranged in the positioning tube 8, the locking column 93 is arranged at the lower end of the locking rod 91, and the locking plate 92 is provided with a locking groove 94 for the locking column 93 to slide.

[0035] like Figure 5 As shown, the locking groove 94 includes an advancing groove 95, a retracting groove 96, and a connecting groove 97. The upper ends of the advancing groove 95 and the retracting groove 96 are connected to each other, and the lower ends gradually move away from each other. The inner side of the upper end connecting position of the advancing groove 95 and the retracting groove 96 is inclined toward the retracting groove 96, and the connecting groove 97 is arranged in an M shape, and the outer side is inclined toward the advancing groove 95.

[0036] Before the striking hammer 3 falls, the positioning rod 81 is pressed to slide downward, and the positioning rod 81 drives the locking rod 91 to move synchronously, and the locking rod 91 drives the locking column 93 to slide downward along the upper position of the forward groove 95, and after being guided by the connecting groove 97, it automatically fits into the middle corner position of the connecting groove 97. At the same time, under the action of the elastic member 82, the positioning rod 81 is fixed.

[0037] When the hammer 3 falls, it first hits the positioning rod 81 and then hits the test piece. When hitting the positioning rod 81, the locking rod 91 drives the locking column 93 to gradually slide into the retreat groove 96 along the connecting groove 97, and finally resets to the upper end position of the forward groove 95. At the same time, under the elastic force of the elastic member 82, the positioning rod 81 is controlled to move upward, and the positioning rod 81 is used to support the hammer 3 to prevent the hammer 3 from hitting the test piece twice, thereby ensuring the measurement accuracy.

[0038] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
