Specific implementation

[0024] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be introduced in further detail below in conjunction with the drawings.

[0025] As Figure 1 Indicated, the utility model provides a kind of engine process hole plugging device, mainly by profile base 1, profile support 2, lower pressing mechanism 3, limiting mechanism 4 and clamping mechanism 5 are formed, and profile support 2 is vertically fixedly installed in the rear portion of profile base 1 by bolt or other fastening mode.Profile base 1 and profile support 2 preferably adopt aluminum alloy section bar, light in weight and high in strength.

[0026] As Figure 2 、 3 Indicated, lower pressing mechanism 3 is installed in the upper portion of profile support 2.The core component thereof includes L-shaped pressing rod 34, first connecting rod 31, second connecting rod 32, third connecting rod 33 and stamping head 35.L-shaped pressing rod 34 is rotatably connected by pivot and ear seat installed on the side of profile support 2 in the turning position.The upper end of first connecting rod 31 is rotatably connected with the end (short arm end) of L-shaped pressing rod 34.The lower end of first connecting rod 31 is rotatably connected with the lower end of second connecting rod 32 and the upper end of third connecting rod 33 by the same pin shaft.The top end of second connecting rod 32 is rotatably connected by another pin shaft and ear seat installed on the top of profile support 2.The bottom end of third connecting rod 33 is fixedly connected with stamping head 35 by screw thread or flange.When operator presses the long arm end of L-shaped pressing rod 34 downward, the linear motion of stamping head 35 in limiting mechanism 4 is finally driven by transmission of the above connecting rod mechanism, and the pressing action is completed.The connecting rod mechanism has labor-saving effect, and operation is easy.

[0027] As Figure 4The limiting mechanism 4 is fixed at the middle part of the profile support 2, right below the pressing mechanism 3. The main body is a limiting shell 41, inside which a limiting groove 42 is processed to cooperate with the punching head 35. The punching head 35 penetrates through the limiting groove 42 and slides up and down in it, and the limiting groove 42 precisely guides the punching head 35 to prevent it from shaking. The limiting shell 41 is also provided with a sliding groove 44 on the side surface, which communicates with the limiting groove 42 and the pin groove 43. The sliding groove 44 is used to supplement the pins, and they are communicated to ensure that the pins can correctly reach the pin groove 43 and will not be stuck.

[0028] As shown in Figure 5 The clamping mechanism 5 is slidingly connected to the front part of the profile base 1. It includes a moving seat 51, an inclined support column 52, an arc support column 53, and two elastic buckles 54. The inclined support column 52 and the arc support column 53 are fixed at the front and rear ends of the moving seat 51, and their upper surfaces are designed to match the shape of the specific part of the engine workpiece to provide stable support. The two elastic buckles 54 are symmetrically installed at the middle part of the moving seat 51, and their clamping jaws face each other and can elastically clamp the workpiece from both sides.

[0029] As shown in Figures 6-8 In order to realize the sliding function, the bottom of the moving seat 51 is fixed with a sliding rail 511. Correspondingly, a first fixing member 11 and a second fixing member 12 are fixed at the front end of the profile base 1 by bolts, and a sliding block 13 matching the sliding rail 511 is installed on the two fixing members. The moving seat 51 is seated on the sliding block 13 through the sliding rail 511 at the bottom thereof and can slide forward and backward along it.

[0030] As shown in Figure 5 , 8 In order to lock the clamping mechanism 5 after adjusting the position, a limiting clamping groove 512 is provided on the bottom side of the moving seat 51. A fixed frame 14 is installed behind the second fixing member 12, and a limiting buckle 15 that can move up and down is arranged in the fixed frame 14. The bottom of the limiting buckle 15 is connected with a spring 16. When the moving seat 51 slides to the predetermined position, the upper end of the limiting buckle 15 will automatically embed into the limiting clamping groove 512 of the moving seat 51 under the elastic force of the spring 16, thereby locking the moving seat 51 and preventing it from moving. When it is needed to adjust again, the limiting buckle 15 can be manually pressed downward to make it disengage from the limiting clamping groove 512. In addition, a baffle 17 is also provided behind the sliding block 13 of the second fixing member 12 to prevent the moving seat 51 from disengaging from the sliding block 13 when it slides backward.

[0031] Working process and principle:

[0032] As shown in Figure 9As shown, in use, the sliding clamping mechanism 5 is moved to a suitable position, at which time the limiting buckle 15 is automatically clamped into the limiting clamping groove 512 under the action of the spring 16, locking the clamping mechanism 5. Then the engine workpiece is placed on the clamping mechanism 5, so that the bottom is supported by the inclined support column 52 and the arc support column 53, and the side is elastically clamped by the two elastic buckles 54. The pin to be pressed is placed in the sliding groove 44 of the limiting mechanism 4. The operator presses the long arm end of the L-shaped pressing rod 34 downward or upward, drives the stamping head 35 to move vertically downward through the connecting rod mechanism, smoothly presses the pin into the process hole until the predetermined pressing depth is reached. After the pressing is completed, the L-shaped pressing rod 34 is lifted, the stamping head 35 is reset under the driving of the connecting rod mechanism, and the workpiece can be taken out.

[0033] The above only describes certain exemplary embodiments of the utility model in a manner of illustration, without doubt, for ordinary skilled in the art, under the condition that the spirit and scope of the utility model are not deviated, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the utility model claims.
