DETAILED DESCRIPTION
[0035] The technical scheme of the utility model will be further described in combination with the embodiments of the utility model and the drawings, but the utility model is not limited to these embodiments.
[0036] As shown in the utility model discloses a pin shearing machine for shearing the pin on the workpiece, and the pin shearing machine comprises a base 1, a feeding piece 3, a pushing piece 5, a cutting piece 6 and a limiting piece 7. Figures 1 to 5
[0037] Specifically, the base 1 is provided with a moving channel 2, and the moving channel 2 is used for arranging the workpiece 4.
[0038] The feeding piece 3 is detachably connected with the base 1, and the feeding piece 3 is provided with a cavity in communication with the moving channel 2, and the workpiece 4 is stacked and placed in the cavity.
[0039] The pushing piece 5 is movably arranged in the moving channel 2, and the activity track of the pushing piece 5 overlaps the intersection of the cavity and the moving channel 2, so as to push the workpiece 4 in the cavity into the moving channel 2.
[0040] The cutting piece 6 is arranged on the base 1 and used for shearing the pin of the workpiece 4 in the moving channel 2.
[0041] The limiting piece 7 is movably arranged on the base 1, and one end of the limiting piece 7 extends into the moving channel 2, so as to limit the workpiece 4.
[0042] When working, first, the feeding piece 3 filled with the workpiece 4 is placed on the base 1. In the initial state, the pushing piece 5 is located below the feeding piece 3 and closes the outlet of the cavity. Figure 3 As shown in the utility model discloses a pin shearing machine for shearing the pin on the workpiece, and the pin shearing machine comprises a base 1, a feeding piece 3, a pushing piece 5, a cutting piece 6 and a limiting piece 7. Figure 3 The pushing piece 5 moves to the right of the base 1, and the workpiece 4 is pushed to move forward along the moving channel 2. After the pushing is completed, the pushing piece 5 moves to the left again, and the communication between the cavity of the feeding piece 3 and the moving channel 2 is re-established, so that more workpieces 4 can continue to enter the moving channel 2, and the workpiece 4 to be processed is provided for the cutting piece 6.
[0043] The workpiece 4 that has been pushed into the moving channel 2 continues to move along the moving channel 2 under the pushing of the subsequent workpiece 4. The limiting member 7 is used to form a limiting area of a specific length in the moving channel 2, and the length of the area can be designed to accommodate only one workpiece 4 or multiple workpieces 4. When the workpiece 4 reaches the working position of the cutting member 6, the cutting member 6 is started to cut off the excess part of the pin of the workpiece 4. The cutting member 6 can process the pins of single or multiple workpieces 4 at a time. The workpiece 4 that has completed the pin trimming continues to move along the moving channel 2 under the pushing of the subsequent workpiece 4, so as to make room for the unprocessed workpiece 4 to move to the position of the cutting member 6 to be processed. The cutting member 6 repeats this process until all the workpieces 4 complete the pin cutting.
[0044] When all the workpieces 4 in the feeding member 3 are transferred to the moving channel 2, the empty feeding member 3 can be detached from the base 1 and replaced with another new feeding member 3 full of workpieces 4. This process is repeated until all the workpieces 4 in the same batch are processed.
[0045] The present scheme realizes the transfer of the workpiece 4 from the feeding member 3 to the moving channel 2 through the pushing member 5, and ensures that the pin of each workpiece 4 is cut to a predetermined length by using the limiting member 7, thereby ensuring the consistency and accuracy of the pin length. The pin length processing is performed before the workpiece 4 is assembled, which effectively simplifies the pin cutting process and improves the work efficiency.
[0046] In the present scheme, the cutting member 6 includes a fixed cutting block 8 connected in the moving channel 2 and a movable cutting block 9 movably arranged on the base 1, and the movable cutting block 9 is located directly above the fixed cutting block 8 and movably abuts against the fixed cutting block 8 to cut the pin.
[0047] When the workpiece 4 moves to the working position of the cutting member 6, the pin thereof abuts against the upper end of the fixed cutting block 8. At this time, the movable cutting block 9 approaches the fixed cutting block 8, and the pin cutting action is completed in the process of closing the two blocks, thereby realizing the pin cutting operation.
[0048] The cutting member 6 further includes a support frame 10 connected to the upper end of the base 1, the support frame 10 is provided with a first through hole 11 communicating with the moving channel 2, the movable cutting block 9 is movably arranged in the first through hole 11 to provide a guide for the movable cutting block 9; a first driving member 12 connected to the support frame 10, and the movable cutting block 9 is connected to the output end of the first driving member 12.
[0049] The support frame 10 is used to mount and position the whole cutting member 6, and the connection between the support frame 10 and the base 1 is preferably achieved by screwing. During the movement of the movable cutting block 9 relative to the fixed cutting block 8, the first through hole 11 on the support frame 10 provides guidance for the movement of the movable cutting block 9, ensuring the accuracy of the pin trimming. The first driving member 12 provides power for the movement of the movable cutting block 9, which can be a pneumatic cylinder, a hydraulic cylinder or a motor.
[0050] The second driving member 13 is connected to the base 1, and the pushing member 5 is connected to the output end of the second driving member 13, so as to drive the pushing member 5 to move in the moving channel 2. Preferably, the second driving member 13 can be a pneumatic cylinder, a hydraulic cylinder or a motor.
[0051] The fixed seat 14 is arranged at the upper end of the base 1, and the fixed seat 14 is provided with a slot 15 communicating with the moving channel 2. The slot 15 is matched with the shape of the feeding member 3, so as to insert the feeding member 3.
[0052] When all the workpieces 4 in the cavity of the feeding member 3 are transported to the moving channel 2, the feeding member 3 filled with new workpieces 4 needs to be replaced. The design of the slot 15 facilitates the quick disassembly and assembly between the feeding member 3 and the fixed seat 14, reduces the time required for replacing the feeding member 3, and thus improves the overall efficiency of the pin trimming.
[0053] Preferably, the fixed seat 14 covers at least a part of the upper end of the moving channel 2, and the width of the slot 15 is greater than the width of the moving channel 2, so as to make the bottom of the feeding member 3 abut against the end face of the base 1 when the feeding member 3 is inserted into the fixed seat 14, thereby providing support for the feeding member 3.
[0054] The sensor 16 is arranged on the fixed seat 14, and the feeding member 3 is provided with a second through hole communicating with the internal space of the feeding member 3. The sensing end of the sensor 16 is opposite to the second through hole, so as to monitor the workpieces 4 on the feeding member 3.
[0055] The sensor 16 is used to monitor the number of workpieces 4 in the feeding member 3 in real time. When all the workpieces 4 in the feeding member 3 are moved to the moving channel 2, the sensor 16 triggers an alarm to remind the operator to replace the feeding member 3 in time, thereby improving the efficiency of the pin trimming.
[0056] In order to ensure that the supply part 3 can be inserted into the slot 15 and its cavity can communicate with the moving channel 2, an opening is arranged on the supply part 3. However, when the supply part 3 full of workpieces 4 is carried, the opening may cause the workpieces 4 to fall out of the cavity. In order to solve this problem, the present scheme is arranged with a limiting groove 17 communicating with the cavity on the supply part 3, and a plug is inserted into the limiting groove 17 to prevent the workpieces 4 in the cavity from falling during the carrying process. Specifically, after the workpieces 4 are stacked, the plug is inserted into the limiting groove 17 to fix the workpieces 4; and before the supply part 3 is inserted into the slot 15, the plug is pulled out so that the workpieces 4 can be smoothly moved from the cavity to the moving channel 2 under the action of the pushing part 5.
[0057] In the present scheme, the base 1 is arranged with a receiving groove 19 communicating with the moving channel 2, and the limiting part 7 includes: a limiting block 18 movably arranged in the receiving groove 19; a connecting rod 20 limitingly connected with the base 1, one end of the connecting rod 20 penetrating through the side wall of the base 1 and being connected with the limiting block 18; and an elastic part sleeved on the outer side wall of the connecting rod 20, the first end of the elastic part abutting against the side wall of the receiving groove 19, and the second end of the elastic part abutting against the limiting block 18.
[0058] Before the workpiece 4 enters the limiting area formed by the limiting part 7 in the moving channel 2, the limiting block 18 is pushed by the elastic part at one end to extend into the moving channel 2 and intersect with the moving path of the workpiece 4. When the pushing part 5 pushes the workpiece 4 into the limiting area, the workpiece 4 will push the limiting block 18 to move towards the receiving groove 19, so that the limiting block 18 moves away from the moving channel 2. At this time, due to the action of the elastic part (preferably a spring), the limiting block 18 can exert a certain resistance on the workpiece 4, so as to ensure that the workpiece 4 accurately reaches the cutting position. The connecting rod 20 (preferably a screw rod) is stably connected and limited with the base 1 through the counter-sunk hole on the base 1 and the head part thereof. Preferably, the limiting block 18 is arranged with a circular arc transition section to facilitate the movement of the limiting block 18 in the receiving groove 19 when the workpiece 4 moves.
[0059] The present scheme further includes: a first guide block 21 connected to one side of the base 1 and having a first inclined groove 22, the base 1 is arranged with a discharging channel 23, one end of the discharging channel 23 communicating with the moving channel 2, and the other end communicating with the first inclined groove 22; and a second guide block 24 connected to one side of the base 1 and having a second inclined groove 25, one end of the moving channel 2 penetrating through the base 1 and communicating with the second inclined groove 25.
[0060] The discharging channel 23 is used to collect the cut pins. The first guide block 21 and the first inclined surface thereon are used to guide the pins out of the base 1.
[0061] The second material guiding block 24 is used for guiding the workpiece 4 after pin cutting to move out, and the second inclined surface is used for guiding the workpiece 4 to a designated position.
