Specifically, in the present embodiment, when the pressing block 120 is located at the first position, the pressing block 120 extends out of the fixing base 110, and the pressing portion 122 is located above the pressing point 210, so that the pressing block 120 can be pressed and held by the pressing point 210, and the problem that the pressing block cannot be pressed and held due to the occupied space above the pressing point 210 is solved; when the pressing block 120 is located at the second position, the pressing block 120 is accommodated in the fixing seat 110, interference on other tests of the crankcase 200 is avoided, and switching of the pressing block 120 between the first position and the second position can be achieved only by rotating the rotating piece 140, so that operation is convenient and fast.
Preferably, the pressing block 120 includes a body 121, and a first sliding portion 123 and a second sliding portion 124 are fixed to the body 121;
the fixed seat 110 is provided with a first sliding slot 111 and a second sliding slot 112, the first sliding portion 123 can slide along the first sliding slot 111, and the second sliding portion 124 can slide along the second sliding slot 112;
the pressing block 120 slides along the first sliding slot 111/the second sliding slot 112 relative to the fixed base 110 to switch the pressing block 120 between a first position and a second position.
The first sliding portion 123 is configured to slide in the first sliding groove 111, and the second sliding portion 124 slides in the second sliding groove 112, so that the pressing block 120 can be switched between the first position and the second position only by driving any one of the first sliding portion 123 and the second sliding portion 124 to slide.
Preferably, the first hinge portion 141 is opened with a third sliding slot 144;
the first sliding portion 123 is provided with a first connecting rod 150, and the first connecting rod 150 is slidably disposed in the first sliding groove 111; the second sliding portion 124 is provided with a second connecting rod 151, the second connecting rod 151 is simultaneously inserted into the second sliding groove 112 and the third sliding groove 144, and the second connecting rod 151 can slide in the second sliding groove 112 and/or the third sliding groove 144.
Specifically, the rotating rod rotates to drive the second connecting rod 151 to slide in the third sliding groove 144, and meanwhile, the connecting rod drives the second sliding portion 124 to slide along the second sliding groove 112, so as to drive the first connecting rod 150 (the first sliding portion 123) to slide in the first sliding groove 111, thereby realizing the sliding of the pressing block 120 relative to the fixing base 110 to switch the first position and the second position.
Preferably, a telescopic cylinder 130 is further included;
the rotating member 140 is further provided with a third hinge 143, the third hinge 143 is located at an end of the second hinge 142 away from the first hinge 141, and the third hinge 143 is hinged to the telescopic rod of the telescopic cylinder 130.
The telescopic cylinder 130 is hinged to the third hinge portion 143, and the telescopic cylinder 130 is telescopic to drive the rotating member 140 to rotate, so as to drive the pressing block 120 to slide.
Preferably, the first sliding chute 111 and the second sliding chute 112 each include a first sliding section 111a and a second sliding section 111b, and the first sliding section 111a is connected to the second sliding section 111 b; the first sliding section 111a gradually inclines towards the direction close to the pressing point 210 from bottom to top; the second sliding section 111b is parallel to the horizontal direction.
Further, the first sliding section 111a is gradually inclined from bottom to top toward the pressing point 210, so that when the rotating member 140 rotates, the pressing block 120 is driven to extend out of the fixing base 110 along the inclined direction (i.e., the height gradually increases while the horizontal position gradually faces the pressing point 210); the second sliding section 111b is parallel to the horizontal direction, so that when the rotating member 140 continues to rotate, the pressing block 120 is driven to gradually move toward the pressing point 210 along the horizontal direction, and finally stops right above the pressing point 210. The pressing block 120 is set to the motion track, so that the space occupied by other parts above the pressing point 210 in the crankcase 200 can be avoided, and the pressing block 120 does not interfere with the crankcase 200 during motion.
The advantage of dividing the movement process of the pressing block 120 into two stages is that when the pressing block 120 is at the first position, that is, when the first sliding portion 123 and the second sliding portion 124 are at the second sliding section 111b, the second sliding section 111b can limit the movement of the pressing block 120 in the vertical direction (the second sliding section 111b is in the horizontal direction), and when the pressing block 120 is pressed and held in the vertical direction, the pressing block 120 does not move, and the condition of the first position is more stable.
Further, providing the first sliding section 111a and the second sliding section 111b may divide the moving stroke of the pressing block 120 into two stages: the first stage, that is, the first sliding section 111a is mainly used to change the vertical position of the pressing block 120, and the first sliding section 111a is inclined so that the process of the rotating member 140 driving the pressing block 120 to move is smoother (it can be understood that if the first sliding section 111a is set to be in the vertical direction, the rotating member 140 is easily stuck in the process of driving the pressing block 120 to move); the second stage, i.e., the second sliding section 111b, is mainly to change the horizontal position of the pressing block 120; and then the motion trail of the pressing block 120 is performed in stages, so that the pressing block is more orderly and more easily controlled.
Compared with the first sliding section and the second sliding section which are directly provided as the arc-shaped sliding grooves and the first sliding section 123 and the second sliding section 124 slide in the arc-shaped sliding grooves to switch the first position and the second position, the first sliding section 111a and the second sliding section 111b in the embodiment are two linear sliding grooves, so that the processing is easier and the state of the first position is more stable.
It should be noted that the above description of the orientation (e.g., horizontal direction, vertical direction, from bottom to top, etc.) can be understood as the description of the state where the working surface of the pressing mechanism 100 is horizontal.
Preferably, when the first sliding portion 123/the second sliding portion 124 slides to the end of the second sliding section 111b far away from the first sliding section 111a, the pressing block 120 is in the first position; when the first sliding portion 123/the second sliding portion 124 slides to the end of the first sliding section 111a far from the second sliding section 111b, the pressing block 120 is in the second position.
This has the advantage that the second/first position can be determined simply by sliding the first/ second slides 123, 124 against the ends of the first/ second slides 111a, 111b without additional positioning operations.
Preferably, in the first sliding groove 111, an end of the second sliding section 111b away from the first sliding section 111a is recessed downward 111 c.
A recess 111c is provided at an end of the second sliding section 111b away from the first sliding section 111a, that is, the recess 111c is provided at the first position, so that the recess 111c can lock the pressing block 120 (the first connecting rod 150 in the pressing block 120), and the pressing block 120 cannot slide along the second sliding section 111b without rotating the rotating member 140.
Further, the recess 111c is provided such that when the pressing block 120 is pressed downward, the first connecting rod 150 has a space movable downward, and thus the pressing portion 122 can press the pressing point 210 downward, instead of the first connecting rod 150 being forced and pressing the recess 111c downward, and finally, the pressing of the crankcase 200 can be achieved.
Preferably, the fixing base 110 includes two fixing plates 113 parallel to each other, and an accommodating space is formed between the two fixing plates 113; the pressing block 120 is movably disposed in the accommodating space.
Two fixed plates 113 are provided, and each fixed plate 113 is provided with a first sliding chute 111, a second sliding and rotating member 140.
Referring to fig. 6-7, the invention further discloses a leak detection device for a crankcase 200, which includes a pressing mechanism 100, and a pressing rod 300, wherein the pressing rod 300 moves along the height direction to drive the pressing portion 122 to abut against the pressing point 210.
Specifically, the pressing rod 300 presses the pressing block 120 downward to drive the pressing portion 122 of the pressing block 120 to press the pressing point 210 of the crankcase 200 downward, so as to realize pressing.
Preferably, two of the pressing mechanisms 100 are disposed on opposite sides of the crankcase 200.
