Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical parts processing, and in particular relates to a positioning mechanism for stamping mechanical parts of precision electronic equipment. Background Art

[0002] Stamping is a forming process that uses a press and a die to apply external force to parts, plates, strips, tubes and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. Stamping can produce workpieces with reinforcing ribs, undulations or flanging that are difficult to manufacture by other methods, thereby increasing their rigidity. During the stamping process, the mechanical parts of precision electronic equipment need to be positioned to prevent the stamped parts from shifting or falling off.

[0003] Among them, Chinese patent CN202321653624.4 discloses a positioning device for stamping hardware parts, including a positioning base, a stamping frame and a positioning mechanism. The stamping frame is located at the upper end of the positioning base, and the positioning mechanism is located on the inner side of the lower end of the stamping frame. A cylinder is positioned at the upper end of the stamping frame, and a piston rod is movably connected to the inner wall of the cylinder. The lower end of the piston rod is fixedly connected to a stamping head.

[0004] Most of the mechanical parts used in existing precision electronic equipment are not equipped with positioning devices during stamping. Most of them rely on manual hand-holding of the parts and then stamping them through machines. However, due to the instability of the stamping process, workers' manual holding of parts is not only prone to errors, but also easily injures their hands during the stamping process, posing certain safety hazards.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] In response to the problems in the related art, the present invention proposes a positioning mechanism for stamping mechanical parts of precision electronic equipment to overcome the above-mentioned technical problems existing in the existing related art.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a positioning mechanism for stamping mechanical parts of precision electronic equipment, comprising a fixed seat, the top end of which is connected to a workbench, a positioning component and an auxiliary component are respectively provided on the workbench, the top end of the fixed seat is connected to a fixing frame, the top end of the fixing frame is connected to a second driving source, and the power output end of the second driving source is connected to a punching head;

[0009] The positioning component is used to position the parts to be stamped, and the auxiliary component is used to assist in further positioning the parts to be stamped.

[0010] Furthermore, the positioning assembly includes two first driving sources, two silicone pads, four connecting rods and two limit blocks. The two first driving sources are both arranged at the top of the workbench, and the power output ends of the two first driving sources are both dynamically connected to the positioning plates. The two silicone pads are respectively arranged at the bottom ends of the two positioning plates, and every two connecting rods are respectively arranged on the surface of each positioning plate. The surface of each limit block is respectively connected to the surface of every two connecting rods, and the bottom ends of the two limit blocks are connected with five sliding balls.

[0011] Furthermore, the auxiliary component includes two fixed plates, two limit plates and four contraction springs. The two fixed plates are arranged on the top of the workbench. Two sliding rods are connected to one side of each of the fixed plates. The surfaces of each two sliding rods are slidably connected with sliders. The two limit plates are respectively arranged on one side of the two sliders, and each contraction spring is respectively sleeved on the outside of each sliding rod.

[0012] Furthermore, the longitudinal sections of each of the limiting blocks and each of the sliding blocks are right-angled trapezoids.

[0013] Furthermore, the surface of each of the five sliding beads is respectively fitted with the top end of each of the sliding blocks.

[0014] Furthermore, the bottom ends of the two sliding blocks and the bottom ends of the two limiting plates are slidably fitted with the top end of the workbench.

[0015] Furthermore, two ends of each of the two contraction springs are respectively connected to one side of each of the fixing plates and the other side of each of the sliding blocks.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model facilitates driving the positioning plate and the silicone pad downward through the first driving source, so as to generate a positioning force on the stamping component from top to bottom. The silicone pad increases the friction between the positioning plate and the stamping component, thereby improving the stability of the stamping component during positioning. Under the driving action of the first driving source, the sliding ball facilitates pushing the slider, so that the two limiting plates are brought close to each other to position the stamping component from both sides, thereby further positioning the stamping component.

[0018] 2. The utility model uses a second driving source to drive the punching head to perform a punching operation on the punching component that has been positioned below. When the sliding ball moves up and does not contact the slider, the contraction of the contraction spring facilitates the separation of the two limit plates from the sides of the punching component, and then facilitates the removal after the punching is completed. The sliding ball reduces the friction between the limit block and the slider, and then the slider is pushed more smoothly.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] See also Figures 1-6 As shown, the utility model is a positioning mechanism for stamping mechanical parts of precision electronic equipment, comprising a fixing base 1, the top of which is connected to a workbench 4, on which a positioning component 2 and an auxiliary component 3 are respectively provided, the top of which is connected to a fixing frame 5, the top of which is connected to a second driving source 6, and the power output end of the second driving source 6 is connected to a punch head 7;

[0032] The positioning component 2 is used to position the parts to be stamped, and the auxiliary component 3 is used to assist in further positioning the parts to be stamped.

[0033] First, place the component on the top surface of the workbench 4, and then position the stamping component from top to bottom through the positioning component 2. While the positioning component 2 is operating, the auxiliary component 3 is pushed to generate an approaching force, thereby positioning the stamping component through clamping on both sides. After the stamping component is completely clamped and positioned, the second driving source 6 drives the stamping head 7 to perform a stamping operation on the stamping component.

[0034] The positioning component 2 facilitates the generation of a positioning force on the stamping component from top to bottom, and the auxiliary component 3 facilitates the positioning of the stamping component through both sides under the driving action of the positioning component 2, thereby facilitating the positioning of the stamping component, and the second driving source 6 facilitates the driving of the stamping head 7 to perform a stamping operation on the stamping component positioned below.

[0035] In one embodiment, for the above-mentioned positioning assembly 2, the positioning assembly 2 includes two first driving sources 201, two silicone pads 203, four connecting rods 204 and two limit blocks 205. The two first driving sources 201 are both arranged at the top of the workbench 4, and the power output ends of the two first driving sources 201 are both poweredly connected to the positioning plates 202. The two silicone pads 203 are respectively arranged at the bottom ends of the two positioning plates 202, and every two connecting rods 204 are respectively arranged on the surface of each positioning plate 202. The surface of each limit block 205 is respectively connected to the surface of every two connecting rods 204, and the bottom ends of the two limit blocks 205 are connected with five sliding balls 206.

[0036] First, place the component on the top surface of the workbench 4, and then synchronously drive the two first driving sources 201 through a switch. The two first driving sources 201 then drive the two positioning plates 202 to move downward, and then position the stamping component from top to bottom through the positioning plates 202 and the silicone pads 203, wherein the friction force of the silicone pads 203 increases the friction between the positioning plates 202 and the stamping component, thereby improving the stability of positioning the stamping component. When the positioning plates 202, connecting rods 204 and limit blocks 205 move downward, the auxiliary components 3 will be driven to move horizontally and approach each other, thereby positioning the stamping component through clamping on both sides, and then after the stamping component is completely clamped and positioned, the second driving source 6 drives the punching head 7 to perform a stamping operation on the stamping component, wherein the sliding ball 206 reduces the friction between the limit block 205 and the auxiliary component 3, thereby more smoothly pushing the auxiliary component 3.

[0037] The first driving source 201 facilitates driving the positioning plate 202 and the silicone pad 203 downward, thereby generating a positioning force on the stamping component from top to bottom, wherein the silicone pad 203 improves the friction between the positioning plate 202 and the stamping component, thereby improving the stability of the stamping component during positioning. The auxiliary component 3 facilitates positioning the stamping component from both sides under the driving action of the first driving source 201, thereby further positioning the stamping component. The sliding ball 206 reduces the friction between the limit block 205 and the auxiliary component 3, thereby pushing the auxiliary component 3 more smoothly. The second driving source 6 facilitates driving the punch head 7 to perform a punching operation on the stamping component positioned below.

[0038] In one embodiment, for the above-mentioned auxiliary component 3, the auxiliary component 3 includes two fixed plates 301, two limit plates 304 and four contraction springs 305. The two fixed plates 301 are both arranged at the top of the workbench 4. Two sliding rods 302 are connected to one side of each of the fixed plates 301. The surfaces of each two sliding rods 302 are slidably connected with sliders 303. The two limit plates 304 are respectively arranged on one side of the two sliders 303. Each contraction spring 305 is respectively mounted on the outside of each sliding rod 302, so as to facilitate the side clamping and limiting of the stamping parts, thereby improving the positioning effect of the stamping parts.

[0039] In one embodiment, for the above-mentioned limit blocks 205 , the longitudinal sections of each limit block 205 and each slider 303 are both right-angled trapezoids, so that the limit blocks 205 can push the slider 303 .

[0040] In one embodiment, for the above-mentioned sliding balls 206, the surfaces of every five sliding balls 206 are respectively fitted with the top of each of the sliders 303, thereby reducing the friction between the limit block 205 and the slider 303 through the sliding balls 206, and then pushing the slider 303 more smoothly.

[0041] In one embodiment, for the above-mentioned slider 303, the bottom ends of the two sliders 303 and the bottom ends of the two limit plates 304 are slidably fitted with the top end of the workbench 4, thereby facilitating the stability of the movement of the slider 303 and the limit plate 304.

[0042] In one embodiment, for the above-mentioned contraction spring 305, the two ends of each two contraction springs 305 are respectively connected to one side of each fixed plate 301 and the other side of each slider 303, so that the elastic contraction action of the contraction spring 305 can drive the slider 303 and the limit plate 304 to separate from the surface of the stamping component when they are not pushed by the limit block 205, thereby facilitating the removal of the stamping component.

[0043] In summary, with the aid of the above technical solution of the present invention, the stamping component is first placed on the top surface of the workbench 4, and then the two first driving sources 201 are synchronously driven to operate through a switch. The two first driving sources 201 then drive the two positioning plates 202 to move downward, and then the stamping component is positioned from top to bottom through the positioning plates 202 and the silicone pads 203, wherein the friction force of the positioning plates 202 in contact with the stamping component is increased by the friction force of the silicone pads 203, thereby improving the stability of positioning the stamping component. When the positioning plates 202, the connecting rods 204 and the limit blocks 205 move downward, the sliding balls 206 arranged at the bottom ends of the two limit blocks 205 will gradually push the two sliders 303 and the two limit plates 304 inward when moving downward, so that the two symmetrically arranged limit plates 304 are close to each other at this time, thereby positioning the stamping component through clamping on both sides. After the stamping component is completely clamped and positioned, the second driving source 6 drives the stamping head 7 to perform stamping operation on the stamping component. When the stamping component needs to be removed, the two first driving sources 201 are driven to operate, and the two positioning plates 202 are driven to move upward by the two first driving sources 201, and then the connecting rod 204 and the limit block 205 are driven to move upward. Then, the two limit plates 304 will elastically reset outward under the contraction action of the contraction spring 305 and the sliding connection action of the slide bar 302, so that the positioning plate 202 and the limit plate 304 are conveniently separated from the stamping component, and then it is convenient to remove the stamped component. The operation is simple and the positioning effect is good. The sliding ball 206 is used to reduce the friction between the limit block 205 and the slider 303, and then the slider 303 is pushed more smoothly, which is convenient for positioning and use of stamping components of the same batch and the same size.

[0044] Through the above technical solution, 1. The first driving source 201 is used to drive the positioning plate 202 and the silicone pad 203 downward, so as to generate a positioning force on the stamping component from top to bottom, wherein the silicone pad 203 improves the friction between the positioning plate 202 and the stamping component, thereby improving the stability of the stamping component during positioning. Under the driving action of the first driving source 201, it is convenient for the sliding ball 206 to push the slider 303, so that the two limiting plates 304 are close to each other to press the stamping component from both sides. Positioning, further positioning the stamping parts; 2. The second driving source 6 is used to drive the punching head 7 to perform a punching operation on the stamping parts positioned below. When the sliding ball 206 moves up and does not contact the slider 303, the contraction of the contraction spring 305 facilitates the separation of the two limit plates 304 from the sides of the stamping parts, and then facilitates the removal after stamping. The sliding ball 206 is used to reduce the friction between the limit block 205 and the slider 303, and then the slider 303 is pushed more smoothly.
