Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, and in particular relates to a mounting fixture for punching holes of metal product parts. Background Art

[0002] Metal products mainly include ferrous metals, non-ferrous metals, alloys and castings. Metal products are turned into high-quality, corrosion-resistant parts through precision machining. The most common ones are auto parts. Since the metal parts of auto parts generally need to be punched during the processing, and when punching the metal parts, it is necessary to install fixtures to fix and clamp them.

[0003] At present, when performing punching operations, threaded rods are usually used to clamp metal product parts. This fixing method can clamp the workpiece well, but it often has the following defects when used: the pressure on the workpiece cannot be controlled when the threaded rod is fixed, which is easy to cause damage to the workpiece, and the various force points of the workpiece cannot be fixed at the same time, causing the workpiece to deflect after fixation, which is easy to cause uneven force on the workpiece after fixation. The uneven force leads to uneven stress inside the workpiece, which is easy to cause the workpiece to be scrapped during the punching operation.

[0004] When installing the workpiece, it is usually placed in the specified position by visual inspection and experience, and then fixed with threaded rods. On the one hand, manual installation and fixation can easily cause workpiece positioning deviation, which is time-consuming and labor-intensive. At the same time, the position of the workpiece cannot be adjusted in time during the fixing process, resulting in poor positioning effect and difficulty in adjustment.

[0005] After the punching operation is completed, the waste generally falls directly downwards. The installation fixture generally adopts an inclined surface design at the bottom so that the falling waste can fall to the specified position along the inclined surface. However, the diameters of the punching holes vary in size. For some waste with larger diameters, it is easy to fall in the opposite direction of the inclined surface, causing the waste to accumulate in the working area. In addition, the falling inclined surface at the bottom of the existing installation fixture cannot be moved, so this problem cannot be solved. Summary of the invention

[0006] The object of the present invention is to provide a mounting fixture for punching metal product parts to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mounting fixture for punching metal product parts, comprising a workbench and a punching mechanism, a support platform is fixedly installed on the top of the workbench, a clamping plate is fixedly installed on the top of the support platform, a power mechanism is arranged at the bottom of the workbench, the other end of the power mechanism penetrates upward through the workbench and the support platform and is fixedly connected to a guide column, a fixing groove is provided at the top of the clamping plate, a fixing spring is movably sleeved inside the fixing groove, a pressure plate is fixedly connected to the bottom end of the fixing spring, and a positioning groove is provided inside the pressure plate The interior of the positioning groove is provided with an adapter block and a positioning ball, and the top of the workbench is provided with a blanking port. The power mechanism will drive the guide column to move downward, and then drive the fixed spring and the pressure plate located inside the fixed groove to move downward. When the bottom of the pressure plate contacts the workpiece, the positioning ball will first make magnetic contact with the workpiece. After the workpiece falls to the ground and is squeezed by the downward moving positioning ball, it can ensure that each force point of the workpiece is subjected to force. At the same time, the downward moving guide column will continuously compress the fixed spring, so that the pressure plate is subjected to downward pressure to complete the clamping and fixing of the workpiece. In conjunction with the positioning ball, the pressure on the workpiece can be balanced.

[0008] Preferably, the punching mechanism is fixedly mounted on the top of the workbench, and the punching mechanism includes a gantry, a cylinder and a die. The gantry is fixedly mounted on the top of the workbench, and the cylinder is fixedly mounted on the top of the gantry. The die is fixedly mounted on the telescopic end of the cylinder by bolts. The bottom end of the outer surface of the guide column is movably sleeved in the interior of the fixed groove and fixedly connected to the top of the fixed spring. The adapter block and the positioning ball are movably sleeved in the interior of the positioning groove. A placement groove is provided on the top of the support table, and a blanking mechanism is provided in the placement groove. When the workpiece is installed, the power mechanism is not started and brought The movable guide column moves downward, at this time the positioning ball will absorb the workpiece and help the staff save effort. As the power mechanism is started and drives the guide column, fixed groove and pressure plate to move downward, the workpiece gradually falls to the ground. At this time, the positioning ball is squeezed by the workpiece toward the inside of the positioning groove and compresses the adapter block to deform it. Then the positioning ball can enter the inside of the positioning groove under the joint pressure of the workpiece and the pressure plate, so that the bottom of the pressure plate completes contact and limit the workpiece. In the process of the positioning ball entering the positioning groove under force, the staff can adjust the position of the workpiece according to the on-site conditions, and the positioning ball can rotate inside the positioning groove, making the adjustment and positioning of the workpiece easier.

[0009] Preferably, the power mechanism includes a hydraulic rod, a driving plate is fixedly installed at the telescopic end of the hydraulic rod, driving columns are fixedly installed at the four corners of the top of the driving plate, the outer surface of the driving column is movably sleeved with a stabilizing spring, the two ends of the stabilizing spring are respectively fixedly connected to the workbench and the driving plate, the driving column passes through the workbench and the support table in sequence upward and is fixedly connected to the guide column, and the power mechanism is responsible for providing downward power for the pressure plate, such as Figure 2As shown, when the hydraulic rod is started, it will drive the driving plate downward to move the driving plate downward, and at the same time drive the driving column downward to move the stabilizing spring. Then, the driving and fixing springs move downward, so that the pressure plate is driven to move downward and press the workpiece. As the driving plate moves downward, the guide column gradually begins to compress the fixing spring and transfers the pressure to the pressure plate, so that the force of the pressure plate to clamp and fix the workpiece is non-rigid, thereby making the force on the workpiece more balanced.

[0010] Preferably, the blanking mechanism includes a guide rail, a movable column is movably sleeved inside the guide rail, a movable plate is fixedly installed on the top of the movable column, a guide plate is fixedly installed on the top of the movable plate, and the guide rail is fixedly sleeved inside the placement groove. The blanking mechanism is responsible for blanking. When the workpiece completes the punching operation, waste materials will fall downward. At this time, the waste materials falling downward will move forward along the inclined surface of the guide plate and enter the designated collection area. When the diameter value of the punching hole changes, the movable plate can be pushed forward or backward to drive the movable column to move inside the guide rail, thereby driving the guide plate to move forward or backward, so that the inclined surface of the guide plate can always be aligned with the blanking port, thereby ensuring the correct direction during blanking.

[0011] Preferably, the adapter block is made of a rubber block, and the bottom of the adapter block fits tightly with the positioning ball. The adapter block is made of a rubber block. When no clamping work is performed, the adapter block and the positioning ball are movably sleeved in the positioning groove. When clamping work is performed, the positioning ball contacts the workpiece and presses the workpiece downward, and is forced to move toward the inside of the positioning groove, thereby compressing the adapter block upward to deform it, so that when the pressure plate completes the clamping work, the positioning ball can enter the inside of the positioning groove and complete the fixation and positioning of the force-bearing point of the workpiece.

[0012] Preferably, the stabilizing spring is in a compressed state in the initial state, and the stabilizing spring is movably sleeved on the bottom end of the outer surface of the driving column. Due to the unstable nature of the hydraulic rod itself, a stabilizing spring is required to provide a buffering function for it. After the hydraulic rod is started and drives the driving plate and the driving column to move downward, the stabilizing spring is compressed to make the movement of the driving plate and the driving column smoother, and there will be no danger of shaking. At the same time, when the clamping work is not performed, the telescopic end of the hydraulic rod is reset. At this time, the stabilizing spring is still in a compressed state, and the reaction force generated by the compression is mainly used to urgently limit the driving plate to maintain the stability of the driving plate and the driving column in the idle state.

[0013] Preferably, a protrusion is provided on the top of the pressure plate, and the protrusion is located inside the fixed groove and fixedly connected to the bottom end of the fixed spring. The pressure plate obtains support through the connection with the fixed spring, and the protrusion on the top of the pressure plate makes the pressure plate more stable and less likely to shake back and forth, and also reduces the degree to which the fixed spring is stretched. When the power mechanism drives the guide column and the fixed groove to move downward, the pressure plate also moves downward, and the protrusion of the pressure plate will leave the inside of the fixed groove. At this time, the bottom of the pressure plate is in contact with the workpiece to maintain its own stability.

[0014] Preferably, the guide rail is made of a rubber block, the length of the guide rail is greater than the length of the moving column, and the moving column is movably sleeved inside the guide rail mainly by squeezing the inner wall of the guide rail to deform it, thereby ensuring the limited fixation of the moving column inside the guide rail. In the absence of strong pressure, the moving column can be stably sleeved inside the guide rail, thereby realizing the forward and backward movement of the guide plate, so that the guide plate can adapt to punching waste of different diameters, and the length of the moving column is designed to provide space for it to move forward and backward inside the guide rail.

[0015] Preferably, the cross-sectional shape of the guide plate is an isosceles triangle, and the surface of the guide plate is polished and ground. The inclined design of the guide plate can effectively guide the punching waste that has fallen. As the guide plate moves, it can adjust its position according to the punching waste of different diameter values, thereby avoiding the accumulation of waste in the working area. The polishing and grinding of the surface further reduces the friction between the waste and the surface of the guide plate, making the waste diversion smoother and preventing the occurrence of accumulation.

[0016] Preferably, the cross-sectional shape of the positioning groove is a combination of a rectangle and a circle with a missing arc portion at the bottom. The positioning ball is located at the bottom of the positioning groove and protrudes from the inside of the pressure plate. The positioning ball is magnetic and can rotate inside the positioning groove. On the one hand, in the initial installation of the workpiece, the positioning ball will be magnetically connected to the workpiece, thereby saving the staff's effort, and the staff can also move the workpiece and adjust the position. In the process of the pressure plate moving downward, the positioning ball begins to contact the workpiece. When the downward pressure applied by the pressure plate is not large, the staff can move the workpiece appropriately and make positioning adjustments. At this time, the positioning ball can rotate with the movement of the workpiece, reducing the resistance of the workpiece during movement, making positioning more convenient. At the same time, as the pressure plate moves downward, the positioning ball begins to contact and pressurize the force point of the workpiece, so that the force on the workpiece is more balanced. As the bottom of the pressure plate is completely in contact with the workpiece, the positioning ball will squeeze the adapter block upward to deform it and enter the interior of the positioning groove, so that the workpiece is more evenly stressed after being fixed.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention realizes the function of balancing the force on the workpiece by providing a support platform, a clamping plate, a power mechanism, a pressure plate, a guide column, a fixing groove and a fixing spring, etc., and drives the driving plate and the driving column to move downward by providing a hydraulic rod, drives the guide column and the fixing spring to move downward, so that the pressure plate moves downward accordingly, and provides a positioning ball to press and preliminarily position the workpiece during the downward movement of the pressure plate to ensure that the workpiece will not shift, so that the bottom of the positioning ball is in perfect contact with each force point of the workpiece, and when the pressure plate moves downward to the bottom and is completely in contact with and fits the workpiece, the adapter block deforms to allow the positioning ball to enter the interior of the positioning groove, and the fixing spring is provided to transmit the pressure from the power mechanism and the guide column to the pressure plate in a non-rigid form, thereby achieving the purpose of balancing the overall force on the workpiece when the bottom of the pressure plate is completely in fit with the workpiece.

[0019] 2. The present invention realizes the convenient positioning and adjustment function of the workpiece by providing a support platform, a clamping plate, a power mechanism, a pressure plate, a guide column, a fixing groove and a fixing spring, and the magnetic positioning ball is provided to absorb the installed workpiece, so that the staff can save effort when installing the workpiece. When the bottom of the workpiece contacts the clamping plate, the positioning ball is continued to be driven downward by the power mechanism, the guide column and the pressure plate to press the workpiece. The adapter block is provided so that the positioning ball can press the workpiece without completely crushing the workpiece, so that the staff can appropriately move and position the workpiece. Since the positioning ball can move inside the positioning groove, the staff can more easily adjust the position of the workpiece, thereby realizing the convenient positioning and adjustment function of the workpiece.

[0020] 3. The present invention realizes a convenient material dropping and diversion function by providing a support platform, a placement slot and a material dropping mechanism. The support platform is provided with a placement slot, so that the material dropping mechanism can be placed. The guide rail is provided, so that the movable column can move inside the guide rail, and the guide rail is squeezed by the movable column due to the rubber characteristics of the guide rail, so as to realize the movement of the movable column inside the guide rail and the limiting and fixing function after the movement, so that the movable plate and the guide plate can move back and forth to avoid the accumulation of waste in the working area.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 9As shown, in the embodiment of the present invention, a punching fixture for metal product parts includes a workbench 1 and a punching mechanism 2. A support platform 3 is fixedly installed on the top of the workbench 1. A clamp 4 is fixedly installed on the top of the support platform 3. A power mechanism 6 is arranged at the bottom of the workbench 1. The other end of the power mechanism 6 upwardly penetrates the workbench 1 and the support platform 3 and is fixedly connected to a guide column 8. The clamp 4 A fixing groove 9 is provided on the top, and a fixing spring 10 is movably sleeved inside the fixing groove 9. The bottom end of the fixing spring 10 is fixedly connected to a pressure plate 7. A positioning groove 71 is provided inside the pressure plate 7. An adapter block 72 and a positioning ball 73 are provided inside the positioning groove 71. A blanking port 12 is provided on the top of the workbench 1. The power mechanism 6 will drive the guide column 8 to move downward, thereby driving the fixing spring 10 and the pressure plate 7 located inside the fixing groove 9 to move downward. When the bottom of the pressure plate 7 contacts the workpiece, the positioning ball 73 will first come into magnetic contact with the workpiece. After the workpiece falls to the ground and is squeezed by the downward moving positioning ball 73, it can ensure that each force point of the workpiece is subjected to force. At the same time, the downward moving guide column 8 will continuously compress the fixing spring 10, so that the pressure plate 7 is subjected to downward pressure to complete the clamping and fixing of the workpiece. In conjunction with the positioning ball 73, the pressure on the workpiece can be balanced.

[0034] Among them, the punching mechanism 2 is fixedly installed on the top of the workbench 1, and the punching mechanism 2 includes a gantry, a cylinder and a die. The gantry is fixedly installed on the top of the workbench 1, and the cylinder is fixedly installed on the top of the gantry. The die is fixedly installed on the telescopic end of the cylinder by bolts. The bottom end of the outer surface of the guide column 8 is movably sleeved in the inside of the fixed groove 9 and is fixedly connected to the top of the fixed spring 10. The adapter block 72 and the positioning ball 73 are both movably sleeved in the inside of the positioning groove 71. A placement groove 11 is opened on the top of the support table 3, and a blanking mechanism 5 is arranged inside the placement groove 11. When installing the workpiece, the power mechanism 6 has not started and driven the guide column 8 to move downward. At this time, the positioning ball 73 will absorb the workpiece and help the staff save effort. After the power mechanism 6 is started and drives the guide column 8, the fixed groove 9 and the pressure plate 7 to move downward, the workpiece gradually falls to the ground. At this time, the positioning ball 73 is squeezed with the workpiece toward the inside of the positioning groove 71 and compresses the adapter block 72 to deform it. Then, the positioning ball 73 can enter the inside of the positioning groove 71 under the joint pressure of the workpiece and the pressure plate 7, so that the bottom of the pressure plate 7 and the workpiece are in contact and limited. In the process of the positioning ball 73 entering the positioning groove 71 under force, the staff can adjust the position of the workpiece according to the on-site conditions, and the positioning ball 73 can rotate inside the positioning groove 71, thereby making the adjustment and positioning of the workpiece easier.

[0035] The power mechanism 6 includes a hydraulic rod 61, a driving plate 62 is fixedly installed at the telescopic end of the hydraulic rod 61, driving columns 63 are fixedly installed at the four corners of the top of the driving plate 62, and the outer surface of the driving column 63 is movably sleeved with a stabilizing spring 64, and the two ends of the stabilizing spring 64 are respectively fixedly connected to the workbench 1 and the driving plate 62, and the driving column 63 passes through the workbench 1 and the support platform 3 in sequence upward and is fixedly connected to the guide column 8. The power mechanism 6 is responsible for providing downward power for the pressure plate 7, such as Figure 2 As shown, when the hydraulic rod 61 is started, it will drive the driving plate 62 downward so that the driving plate 62 moves downward, and at the same time drive the driving column 63 downward, the stabilizing spring 64 is compressed, and then drive the guide column 8 and the fixed spring 10 to move downward, so that the pressure plate 7 is driven to move downward and press the workpiece. As the driving plate 62 moves downward, the guide column 8 gradually begins to compress the fixed spring 10 and transfers the pressure to the pressure plate 7, so that the force of the pressure plate 7 to clamp and fix the workpiece is non-rigid, so that the force on the workpiece is more balanced.

[0036] Among them, the blanking mechanism 5 includes a guide rail 51, a moving column 52 is movably sleeved inside the guide rail 51, a moving plate 53 is fixedly installed on the top of the moving column 52, and a guide plate 54 is fixedly installed on the top of the moving plate 53. The guide rail 51 is fixedly sleeved inside the placement groove 11. The blanking mechanism 5 is responsible for blanking. When the workpiece completes the punching operation, waste materials will fall downward. At this time, the waste materials falling downward will move forward along the inclined surface of the guide plate 54 and enter the designated collection area. When the diameter value of the punching hole changes, the moving plate 53 can be pushed forward or backward to drive the moving column 52 to move inside the guide rail 51, thereby driving the guide plate 54 to move forward or backward, so that the inclined surface of the guide plate 54 can always be aligned with the blanking port 12 to ensure the correct direction during blanking.

[0037] Among them, the adapter block 72 is made of a rubber block, and the bottom of the adapter block 72 fits tightly with the positioning ball 73. The adapter block 72 is made of a rubber block. When no clamping work is performed, the adapter block 72 and the positioning ball 73 are movably connected in the positioning groove 71. When the clamping work is performed, the positioning ball 73 contacts the workpiece and presses the workpiece downward, and will be forced to move toward the inner direction of the positioning groove 71, thereby compressing the adapter block 72 upward to deform it, so that when the pressure plate 7 completes the clamping work, the positioning ball 73 can enter the interior of the positioning groove 71 and complete the fixation and positioning of the force-bearing point of the workpiece.

[0038] Among them, the stabilizing spring 64 is in a compressed state in the initial state, and the stabilizing spring 64 is movably sleeved on the bottom end of the outer surface of the driving column 63. Due to the unstable characteristics of the hydraulic rod 61 itself, the stabilizing spring 64 is needed to provide it with a buffering function. After the hydraulic rod 61 is started and drives the driving plate 62 and the driving column 63 to move downward, the stabilizing spring 64 is compressed to make the movement of the driving plate 62 and the driving column 63 more stable, and there will be no danger of shaking. At the same time, when the clamping work is not performed, the telescopic end of the hydraulic rod 61 is reset. At this time, the stabilizing spring 64 is still in a compressed state, and the reaction force generated by the compression is mainly used to urgently limit the driving plate 62 to maintain the stability of the driving plate 62 and the driving column 63 in the idle state.

[0039] Among them, a protrusion is provided on the top of the pressure plate 7, and the protrusion is located inside the fixing groove 9 and is fixedly connected to the bottom end of the fixing spring 10. The pressure plate 7 obtains support through the connection with the fixing spring 10, and the protrusion on the top of the pressure plate 7 makes the pressure plate 7 more stable and not easy to shake back and forth, and also reduces the degree to which the fixing spring 10 is stretched. When the power mechanism 6 drives the guide column 8 and the fixing groove 9 to move downward, the pressure plate 7 also moves downward, and the protrusion of the pressure plate 7 will leave the inside of the fixing groove 9. However, at this time, the bottom of the pressure plate 7 is in contact with the workpiece to maintain its own stability.

[0040] Among them, the guide rail 51 is made of rubber blocks, and the length of the guide rail 51 is greater than the length of the moving column 52. The moving column 52 is movably sleeved inside the guide rail 51 mainly by squeezing the inner wall of the guide rail 51 to deform it, thereby ensuring the limited fixation of the moving column 52 inside the guide rail 51. In the absence of strong pressure, the moving column 52 can be stably sleeved inside the guide rail 51, thereby realizing the forward and backward movement of the guide plate 54, so that the guide plate 54 can adapt to punching wastes of different diameters, and the length of the moving column 52 is designed to provide space for it to move forward and backward inside the guide rail 51.

[0041] Among them, the cross-sectional shape of the guide plate 54 is an isosceles triangle, and the surface of the guide plate 54 is polished and ground. The inclined surface design of the guide plate 54 can effectively guide the punching waste that falls down. As the guide plate 54 moves, it can adjust its position according to the punching waste of different diameter values, thereby avoiding the accumulation of waste in the working area. The polishing and grinding of the surface further reduces the friction between the waste and the surface of the guide plate 54, making the waste diversion smoother and preventing the occurrence of accumulation.

[0042] The cross-sectional shape of the positioning groove 71 is a combination of a rectangle and a circle with a missing arc portion at the bottom. The positioning ball 73 is located at the bottom of the positioning groove 71 and protrudes from the inside of the pressure plate 7. The positioning ball 73 is magnetic and can rotate inside the positioning groove 71. On the one hand, in the initial installation of the workpiece, the positioning ball 73 will be magnetically connected to the workpiece, thereby saving the staff's effort, and the staff can also move the workpiece and adjust the position. In the process of the downward movement of the pressure plate 7, the positioning ball 73 begins to contact the workpiece. When the downward pressure applied by the pressure plate 7 is not large, the staff can move the workpiece appropriately and make positioning adjustments. At this time, the positioning ball 73 can rotate with the movement of the workpiece, reducing the resistance of the workpiece during movement, making positioning more convenient. At the same time, as the pressure plate 7 moves downward, the positioning ball 73 begins to contact and pressurize the force point of the workpiece, making the force on the workpiece more balanced. As the bottom of the pressure plate 7 is completely in contact with the workpiece, the positioning ball 73 will squeeze the adapter block 72 upward to deform it and enter the interior of the positioning groove 71, so that the workpiece is more evenly stressed after being fixed.

[0043] Working principle and usage process:

[0044] First, the workpiece is inserted into the bottom of the pressing plate 7 so that the positioning ball 73 contacts the workpiece and completes the magnetic connection. The workpiece is moved and the position is adjusted to drive the positioning ball 73 to rotate, and the hydraulic rod 61 is started to drive the driving plate 62 and the driving column 63 to move downward, so that the stabilizing spring 64 is stretched, and the guide column 8 and the fixing groove 9 are driven to move downward, and the pressing plate 7 drives the workpiece to move downward accordingly;

[0045] Then, after the workpiece falls on the top of the clamping plate 4, the driving plate 62 and the driving column 63 continue to move downward, and the guide column 8 begins to compress the fixing spring 10 downward. At this time, the pressure on the pressing plate 7 is received by the fixing spring 10 and presses the positioning ball 73 downward. The bottom of the positioning ball 73 contacts the workpiece and gradually applies pressure to the workpiece. The staff can pull the workpiece according to the position of the workpiece and drive the positioning ball 73 to rotate. After the adjustment is completed, as the pressure applied by the guide column 8 to the fixing groove 9 increases, the positioning ball 73 begins to compress the adapter block 72 upward to deform it, and then enters the interior of the positioning groove 71. At this time, the bottom of the pressing plate 7 is completely in contact with the workpiece and completes the fixation of the workpiece.

[0046] Finally, the workpiece is punched so that the waste generated by the processing falls onto the guide plate 54 along the drop port 12, and then falls into the collection area, pushing the movable plate 53 forward or pulling backward to drive the guide plate 54 and the movable column 52 to move forward and backward, so that the movable column 52 moves inside the guide rail 51, and then the guide plate 54 stays at the specified position to provide guidance and guidance for the falling of the waste.
