[0002] A pulse generator is a signal source that can generate pulse signals of different frequencies and waveforms. It is used to simulate various signals by controlling the output parameters such as duty cycle, frequency and amplitude. It is widely used in the fields of communication, medical treatment and radar. When assembling the pulse generator, the outer shell needs to be supported and fixed, and then multiple circuit boards are fixed inside the outer shell. Existing assembly clamping devices generally have the problems of time-consuming clamping action and excessive space occupied above the clamp arm due to leakage, which brings inconvenience to product assembly.

[0003] For example, a clamping device is disclosed in the Chinese utility model patent with the announcement number CN216127120U, including a base plate and a clamping arm. Although the solution can form a clamping and fixing effect by the cooperation between the movable arm and the fixed arm, the driving assembly of the clamping device moves slowly, and the movable arm and the fixed arm are exposed outside the workbench, occupying space and affecting the product process operation and processing. Based on this, a clamping device for assembling a pulse generator is proposed. Utility Model Content

[0007] As a further improvement of the above scheme, the slider driving mechanism includes a cylinder fixedly connected to the upper side of the base, the output end of the cylinder is fixedly connected to a connecting plate, the upper side of the connecting plate is respectively fixedly connected with a No. 1 wedge push plate and a No. 2 wedge push plate that cooperate with the No. 2 wedge slider and the No. 1 wedge slider, and a calibration detection mechanism is provided on one side of the connecting plate to align the No. 2 wedge slider and the No. 1 wedge slider with the No. 1 wedge push plate and the No. 2 wedge push plate respectively.

[0008] As a further improvement of the above solution, the calibration detection mechanism includes a limiting slide bar fixedly connected to the upper side of the base and slidably connected to one side of the connecting plate, and the upper end of the limiting slide bar is fixedly connected to a laser rangefinder.

[0009] As a further improvement of the above solution, the turntable driving mechanism is a bracket fixedly connected to the upper side of the base and rotatably connected to the lower side of the turntable, and the upper side of the base is fixedly connected to a servo motor connected to the lower side of the turntable.

[0020] Please combine Figure 1-Figure 3 A clamping device for assembling a pulse generator in this embodiment includes a base 1 and a turntable 8 located above the base 1, six assembly tables 2 are fixedly connected to the periphery of the turntable 8, and the upper sides of the six assembly tables 2 are fixedly connected to a fixing plate 10 and a fixing rod 9, and the upper sides of the six assembly tables 2 are provided with a first clamping rod mechanism and a second clamping rod mechanism for clamping the pulse generator from the side, and a turntable driving mechanism for rotating the turntable 8 is provided on the upper side of the base 1.

[0021] The connection form between the turntable 8 and the assembly platform 2 can be determined according to the specific situation, such as Figure 1 As shown, the assembly table 2 and the turntable 8 are externally connected, and can also be embedded in the upper part; the number of assembly tables 2 is at least 2, which can be determined according to the specific production line capacity.

[0022] The first clamping rod mechanism includes a No. 1 limit groove 4 opened on the assembly platform 2, a No. 1 push rod 3 is slidably connected to the inner side of the No. 1 limit groove 4, a No. 1 limit cylinder 17 is fixedly connected to the lower side of the assembly platform 2, a No. 1 wedge-shaped slider 16 fixedly connected to the lower end of the No. 1 push rod 3 is slidably connected to the inner side of the No. 1 limit cylinder 17, and a No. 1 spring 18 is arranged between the No. 1 wedge-shaped slider 16 and the No. 1 limit cylinder 17.

[0023] The second clamping rod mechanism includes a No. 2 limiting groove 6 opened on the assembly platform 2, a No. 2 push rod 5 is slidably connected to the inner side of the No. 2 limiting groove 6, a No. 2 limiting cylinder 20 is fixedly connected to the lower side of the assembly platform 2, a No. 2 wedge-shaped slider 21 fixedly connected to the lower end of the No. 2 push rod 5 is slidably connected to the inner side of the No. 2 limiting cylinder 20, a No. 2 spring 19 is arranged between the No. 2 wedge-shaped slider 21 and the No. 2 limiting cylinder 20, and a slider driving mechanism is arranged above the base 1 to make the No. 2 wedge-shaped slider 21 and the No. 1 wedge-shaped slider 16 move to one side along the No. 2 limiting cylinder 20 and the No. 1 limiting cylinder 17 respectively.

[0024] The No. 1 spring 18 and the No. 2 spring 19 are mainly used to open the No. 1 push rod 3 and the No. 2 push rod 5 by utilizing their own elasticity when the No. 2 wedge-shaped push plate 15 is out of contact with the No. 1 wedge-shaped push plate 11.

[0025] The slider driving mechanism includes a cylinder 13 fixedly connected to the upper side of the base 1, and the output end of the cylinder 13 is fixedly connected to a connecting plate 14, and the upper side of the connecting plate 14 is respectively fixedly connected to a No. 1 wedge push plate 11 and a No. 2 wedge push plate 15 that cooperate with the No. 2 wedge slide 21 and the No. 1 wedge slide 16, and a calibration detection mechanism is provided on one side of the connecting plate 14 to align the No. 2 wedge slide 21 and the No. 1 wedge slide 16 with the No. 1 wedge push plate 11 and the No. 2 wedge push plate 15 respectively.
