Detailed Description
As shown in the figure, the clamp for machining the gear key groove comprises a mounting seat 101, and the mounting seat 101 can be fixedly mounted on a working table through bolts. The mounting seat 101 is provided with a double-jaw manual chuck 102, and the double-jaw manual chuck 102 is provided with a fixture block 103, so that the fixture block 103 can perform linear motion along the sliding groove of the double-jaw manual chuck 102 along the radial direction of the double-jaw chuck 102. A vertical rod 104 is fixedly arranged on the clamping block 103 through welding, a cross rod 105 is fixedly arranged on the upper portion of the vertical rod 104 close to the side of the central axis of the double-jaw manual chuck 102 through welding, a reinforcing rib 114 is fixedly arranged at an included angle between the cross rod 105 and the vertical rod 104 through welding, and the reinforcing rib 114 can improve the mounting stability between the vertical rod 104 and the cross rod 105. A pressing mechanism capable of moving up and down is installed at one end, close to the central axis of the double-jaw manual chuck 102, of the cross rod 105, the pressing mechanism is a screw 115, the screw 115 is installed in a threaded hole formed in one end, close to the central axis of the double-jaw manual chuck 102, of the cross rod 105 in a matched mode, and the screw 115 can move linearly along the circumferential direction of the double-jaw manual chuck 102 by screwing the screw 115. The lower end of the screw 115 is also fitted with a rubber block 116. The two sides of the central axis of the double-jaw hand chuck 102 are symmetrically fixedly provided with cushion blocks 107 by welding, and the cushion blocks 107 are positioned between the sliding grooves of the double-jaw hand chuck 102 and the central axis of the double-jaw hand chuck 102. The gear 106 to be machined can be placed on the cushion block 107, then the clamping block 103 drives the cross rod 105 to move towards the gear 106, the pressing mechanism is located above the gear 106, the screw 115 is screwed, the rubber block 116 presses the gear 106, and then the gear 106 is machined. When the next gear needs to be processed, the screw 115 is only required to be screwed to enable the rubber block 116 to be far away from the gear, and then the gear is dismounted; when gears with different sizes need to be machined, only the fixture block 103 needs to be adjusted.
The two arc grooves 108 are symmetrically arranged on two sides of the central axis of the double-jaw hand chuck 102, and the arc grooves 108 are located at one end, away from the central axis of the double-jaw hand chuck 102, of the cushion block 107, namely, the cushion block 107 is located between the two arc grooves 108. The sliding block 113 is slidably installed in the arc groove 108, the sliding block 113 is fixedly installed with an installation rod 111 through welding, through holes 118 are uniformly distributed on the installation rod 111, and the central line of the through holes 118 is perpendicular to the central axis of the double-jaw manual chuck 102. The mounting rod 111 is further uniformly provided with a second through hole, and the center line of the second through hole is perpendicular to the center line of the first through hole 118. The radius of fingerpin 110 is equal to the radius of through-hole one 118 so that fingerpin 110 may be inserted within through-hole one 118. The finger rod 110 is uniformly provided with a third through hole 117, the radius of the third through hole 117 is equal to that of the second through hole, so that after the finger rod 110 is inserted into the first through hole 118, the finger rod 110 can be adjusted to enable one end of the finger rod 110 to abut against the gear 106, and then the bolt 112 is inserted into the second through hole and the third through hole 117, so that the finger rod 110 cannot move relative to the mounting rod 111.
