Description

Technical Field

[0001] The utility model belongs to the technical field of pressure plates of hole testing machines, in particular to a pressure plate device of the hole testing machine. Background Art

[0002] A hole tester is a professional device specially used to detect the quality, diameter, verticality and condition of drilling holes. It is commonly used in mechanical manufacturing, construction engineering, aerospace and other fields. It ensures that the drilled holes meet the design requirements and assembly accuracy by accurately measuring and analyzing various parameters of the holes. The pressure plate can be used to stabilize the plate of the hole to be inspected to ensure that the plate will not move during measurement, thereby affecting the accuracy of the measurement results.

[0003] The existing pressure plate device of the hole inspection machine may generate a large impact force when the pressure plate is pressed down quickly to contact the board body due to the lack of a buffering process, and may also affect the position accuracy of the holes on the board. Especially in the production of precision PCB boards, the lack of buffering may cause the board to produce a slight displacement due to uneven pressure, thereby affecting the subsequent aperture detection accuracy. Utility Model Content

[0004] In view of this, the utility model aims to address the deficiencies in the prior art and provides a pressure plate device for a hole testing machine. The buffer mechanism can effectively absorb the kinetic energy generated during the downward pressing process, reduce the impact force, avoid damage to the plate body, and help maintain the position of the hole to be tested stable, thereby improving the detection accuracy.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: the pressure plate device of the hole testing machine includes a mounting plate, and the four corners of the upper end of the mounting plate are respectively welded and fixed with support frames, a rectangular plate is arranged between the upper ends of the four support frames, and two sliding plates are slidably connected inside the rectangular plate, and a connecting frame is arranged at the lower end of the rectangular plate, and two screw rods are arranged for rotation inside the connecting frame, and the thread directions of the two screw rods are opposite, and the sliding plates are respectively threadedly connected with adjacent screw rods, and an electric drive unit for driving the two screw rods to rotate is arranged on the bottom wall of the connecting frame, and a buffer pressing mechanism is arranged at the upper ends of the two sliding plates, and a pushing mechanism is arranged inside the two sliding plates, and the electric drive unit includes a double-axis motor arranged on the bottom wall of the connecting frame, and the output shafts on the left and right sides of the double-axis motor are respectively connected to the relative inner ends of the adjacent screw rods through couplings, and the buffer pressing mechanism includes two screw rods respectively arranged on the two sliding plates The cam is provided with a plurality of springs, each of which is provided with a plurality of springs, and the plurality of springs are connected to each other with a plurality of springs, and the plurality of springs are connected to each other with a plurality of springs.

[0006] As a further improvement of the utility model, a control panel is arranged at the upper end of the mounting plate, and the dual-axis motor, the electric push rod 1 and the electric push rod 2 are all electrically connected to the control panel.

[0007] As a further improvement of the utility model, four mounting holes are provided inside the mounting plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, by placing the plate body on the flexible pads on the upper ends of the two docking plates, and then controlling the dual-axis motor to rotate, the output shaft rotates to drive the screws on both sides to rotate. Since the screw threads on both sides are in opposite directions, the sliding plates move closer to each other, and the two sides of the plate body can be quickly clamped.

[0010] Secondly, by controlling the opening of the electric push rod, the connecting plate moves downward. Due to the elastic buffering force of the spring and the sliding friction damping of the sliding column on the connecting plate, the pressure plate moves downward and realizes flexible contact with the plate body. The buffer mechanism can effectively absorb the kinetic energy generated during the downward pressure process, reduce the impact force, avoid damage to the plate body, and help to maintain the position of the hole to be detected stable, thereby improving the detection accuracy.

[0011] Thirdly, the holes on the plate are inspected through an external inspection mechanism. After the inspection, the electric push rod 1 is turned on to move upward, and then the electric push rod 2 is turned on and operated by control. The telescopic end drives the push plate to move backward to push the plate onto the roller. The plate slides off the roller due to its own gravity, completing the unloading of the plate, which is convenient for personnel to continuously inspect the plate.

[0012] Fourthly, the pressing plate device can be fixed through the mounting holes on the mounting plate, so that the operation of the pressing plate device is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, the pressure plate device of the hole testing machine includes a mounting plate 101: support frames 103 are welded and fixed to the four corners of the upper end of the mounting plate 101, a rectangular plate 104 is arranged between the upper ends of the four support frames 103, two sliding plates 201 are slidably connected inside the rectangular plate 104, a connecting frame 204 is arranged at the lower end of the rectangular plate 104, two screw rods 210 are rotatably arranged inside the connecting frame 204, the thread directions of the two screw rods 210 are opposite, the sliding plates 201 are respectively threadedly connected to the adjacent screw rods 210, an electric drive unit for driving the two screw rods 210 to rotate is arranged on the bottom wall of the connecting frame 204, a buffer pressing mechanism is arranged on the upper ends of the two sliding plates 201, a pushing mechanism is arranged inside the two sliding plates 201, the electric drive unit includes a double-axis motor 211 arranged on the bottom wall of the connecting frame 204, and the output shafts on the left and right sides of the double-axis motor 211 are respectively connected to the relative inner ends of the adjacent screw rods 210 through couplings.

[0021] like Figure 1 , 2 As shown in Figures 3 and 4, the buffering and clamping mechanism includes four electric push rods 203 respectively arranged on two sliding plates 201, a connecting plate 202 is respectively arranged between the lower ends of the telescopic ends of two adjacent electric push rods 203, the interiors of the two connecting plates 202 are slidably connected to two sliding columns 205, a pressing plate 207 is respectively arranged between the lower ends of two adjacent sliding columns 205, a flexible pad 209 is bonded to the upper ends of the two pressing plates 207, docking plates 208 are respectively arranged on the relative inner sides of the two sliding plates 201, the pressing plates 207 are respectively installed in cooperation with the adjacent docking plates 208, an elastic buffer component is arranged between the connecting plate 202 and the pressing plate 207, the buffer component includes springs 206 respectively arranged between the connecting plate 202 and the pressing plate 207, and the four springs 206 are respectively sleeved on the corresponding outer arc surfaces of the sliding columns 205.

[0022] like Figure 1 , 2 As shown in Figures 3 and 4, the pushing mechanism includes a pushing plate 304 sliding inside the two sliding plates 201, and electric push rods 303 are arranged on the outer sides of the two sliding plates 201. The telescopic ends of the two electric push rods 303 are respectively connected to the rear sides of the adjacent pushing plates 304. A frame 301 is arranged on the rear side of the rectangular plate 104, and a plurality of rollers 302 are rotatably connected inside the frame 301.
