Description

Technical Field

[0001] This invention relates to the field of clamping devices, and more specifically to a clamping device for electronic product manufacturing. Background Technology

[0002] In the processing of electronic products, most of the casings need to be positioned and clamped in order to carry out subsequent operations such as drilling and grinding. In the clamping and positioning, appropriate clamping devices are required to ensure that the casings are well fixed during the processing and to avoid accidents during the processing.

[0003] Chinese invention patent CN104842176A discloses a quick-clamping fixture, comprising a pressure plate, a connecting rod, a T-nut, and an eccentric semicircular block. The pressure plate passes through the middle of the connecting rod, and the lower end of the connecting rod is fixedly connected to the worktable via the T-nut. The eccentric semicircular block is rotatably connected to the upper part of the connecting rod via a pin. A beveled washer fitted onto the connecting rod is mounted on the pressure plate. A return spring is fitted onto the connecting rod located between the pressure plate and the worktable. A rotating handle is provided on the eccentric semicircular block. When the pressure plate is clamped, the eccentric semicircular block and the beveled washer are in a self-locking contact connection. However, in actual operation, the contact surface between the pressure plate and the workpiece is only a single line, which cannot guarantee a proper fit. If vibration or eccentric force occurs, dislocation is very likely to occur. Furthermore, in actual operation, it is impossible to properly control the downward pressure, which may lead to damage to the housing. Summary of the Invention

[0004] This invention provides a clamping device for electronic product manufacturing, which solves the technical problem that electronic products are damaged due to the inability to reasonably control the pressure and fit of the pressure surface when fixing them.

[0005] The clamping device for electronic product manufacturing of the present invention adopts the following technical solution: it includes a support mechanism for pressing and clamping the electronic product, a traction mechanism for adapting to the outer contour of the electronic product, and a locking mechanism for steplessly adjusting the downward pressure of the support mechanism. The traction mechanism is installed on the lower front end of the support mechanism, and the locking mechanism is installed on the rear end of the support mechanism.

[0006] The support mechanism includes a pressure rod, a vertical pole connected to the lower rear end of the pressure rod, a fixed seat sleeved on the lower end of the vertical pole, a lower pressure frame connected to both ends of the fixed seat by pins, a rocker arm connected to the middle of the lower pressure frame by a locking mechanism, and the other end of the rocker arm connected to the vertical pole by a pin.

[0007] Furthermore, the traction mechanism includes a pressure seat, the upper end of which is connected to a pressure rod via a fixing block. The pressure rod has a limiting groove formed on it to match the fixing block. Two positioning pins are connected through the fixing block. The pressure rod has sliding limiting grooves symmetrically arranged corresponding to the positioning pins. A return spring is installed inside the sliding limiting groove. Five locking pins are installed on the pressure seat. The upper end of each locking pin extends into the pressure seat. A locking plate is installed inside the pressure seat. The locking plate has locking grooves formed corresponding to the locking pin positions. The upper end of the locking plate is connected to the positioning pins via a connecting rod.

[0008] Furthermore, the locking mechanism includes an outer ring mounted on a rocker arm, an inner cylinder fitted inside the outer ring, and the inner cylinder connected to a lower pressure frame. Holes are opened at the upper and lower ends of the inner cylinder, and locking blocks are installed in the holes. The inner cylinders are connected by a handle, and a telescopic rod is installed inside the handle corresponding to the position of the locking block. The side of the telescopic rod away from the locking block is a slope, and a button is installed on the slope. The button is connected to the handle through a return spring.

[0009] Furthermore, the positioning pin slides laterally inside the fixed block, and the sliding limiting groove is offset to one side, forming an arc shape.

[0010] Furthermore, the opening cross-section of the lock groove is a regular hexagon.

[0011] Furthermore, a pressure rod is installed inside the sliding limit groove located on the rear side. The pressure rod is located inside the return spring, and a pressure gauge is installed on the upper end of the pressure rod, with the pressure rod corresponding to the pressure gauge.

[0012] Furthermore, the locking pin is slidably connected to the pressure seat, and the upper end of the locking pin is connected to the pressure seat via a pressure spring.

[0013] Furthermore, the inner cylinder is connected to the handle via a thread, the locking block is slidably connected to the inner cylinder, and the outer ring is connected to the rocker arm via welding.

[0014] Furthermore, the outer surface of the lock block is formed with friction texture.

[0015] Furthermore, the side of the telescopic rod corresponding to the locking block is a conical surface, and the telescopic rod is slidably connected to the inner cylinder.

[0016] The beneficial effects of this invention are as follows: This invention utilizes an adaptable locking post in conjunction with a fixing block that can move outward during contraction, ensuring the fit of the mating surfaces of the TV frame in the initial stage of fixing, thereby preventing displacement during fixing. Furthermore, the inner cylinder that can be locked at any time, combined with a pressure gauge, allows for timely monitoring of pressure and avoids overpressure, thus ensuring the fixing effect and safety of the TV frame.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] An embodiment of the clamping device for electronic product manufacturing according to the present invention, such as... Figures 1 to 8 As shown, it includes a support mechanism 1 for pressing and clamping the outer casing of electronic products such as television frames, a traction mechanism 2 for adapting to the outer contour of electronic products, and a locking mechanism 3 for steplessly adjusting the downward pressure of the support mechanism 1. The traction mechanism 2 is installed on the lower front end of the support mechanism 1, and the locking mechanism 3 is installed on the rear end of the support mechanism 1.

[0029] The support mechanism 1 includes a pressure rod 11, with a vertical rod 12 connected to the lower rear end of the pressure rod 11. A fixed seat 13 is sleeved on the lower end of the vertical rod 12. The fixed seat 13 is fixedly installed at the four corners of the table (not shown in the figure). The two ends of the fixed seat 13 are connected to the lower pressure frame 14 through pins. A rocker arm 15 is connected to the middle of the lower pressure frame 14 through a locking mechanism 3. The other end of the rocker arm 15 is connected to the vertical rod 12 through a pin.

[0030] The traction mechanism 2 includes a pressure seat 21. The upper end of the pressure seat 21 is connected to the pressure rod 11 via a fixing block 22. The pressure rod 11 has a limiting groove formed to match the fixing block 22. Two positioning pins 24 are connected through the fixing block 22. The pressure rod 11 has sliding limiting grooves 25 symmetrically arranged corresponding to the positioning pins 24. A return spring is installed inside the sliding limiting grooves 25. Five locking pins 23 are installed on the pressure seat 21. The upper end of the locking pins 23 extends into the pressure seat 21. A locking plate 27 is installed inside the pressure seat 21. The locking plate 27 has a locking groove 28 formed corresponding to the position of the locking pins 23. The upper end of the locking plate 27 is connected to the positioning pins 24 via a connecting rod.

[0031] The locking mechanism 3 includes an outer ring 31, which is mounted on the rocker arm 15. An inner cylinder 32 is fitted inside the outer ring 31 and connected to the lower pressure frame 14. Holes are opened at both ends of the inner cylinder 32, and locking blocks 33 are installed in the holes. The inner cylinders 32 are connected by a handle 35. A telescopic rod 34 is installed inside the handle 35 corresponding to the position of the locking block 33. The side of the telescopic rod 34 away from the locking block 33 is inclined, and a button 36 is installed on the inclined side. The button 36 is connected to the handle 35 through a return spring.

[0032] Furthermore, such as Figure 6As shown, the positioning post 24 slides laterally inside the fixing block 22, and the sliding limiting groove 25 is tilted to one side. The sliding limiting groove 25 is arc-shaped. When the pressure seat 21 is subjected to pressure from above and below and retracts into the limiting groove of the pressure rod 11, the arc-shaped sliding limiting groove 25, together with the positioning post 24, enables the positioning post 24 to drive the fixing block 22 to move to the rear and inward, thereby pulling the TV frame to both sides to stretch and fix it. At the same time, because the positioning post 24 is offset to one side, the positioning post 24 can also be laterally offset relative to the fixing block 22, so that the positioning post 24 can drive the locking groove 28 to lock the locking post 23, ensuring the position of the locking post 23, so that the locking post 23 can always fit the contour of the TV frame. Moreover, the lateral offset of the positioning post 24 relative to the fixing block 22 can also stretch the TV frame in the length direction, so that the clamping surface of the TV frame is flat, which facilitates the processing of the battery frame.

[0033] It is understandable that TV frames are mostly supported by thin aluminum plates or aluminum alloy plates, which are generally not very rigid and are often very long. Therefore, pulling the TV frame at both ends along its length can stretch the TV frame.

[0034] It should be added that, for example Figure 4 and Figure 5 As shown, the positioning post 24 is located via a vertical plate ( Figure 5 (Not marked in the text) is fixedly connected to the locking plate 27. The groove depth of the sliding limiting groove 25 gradually changes from bottom to top along the extension direction of the sliding limiting groove 25. Thus, when the positioning post 24 slides along the sliding limiting groove 25, the positioning post 24 can slide along the thickness direction of the sliding limiting groove 25. This allows the positioning post 24 to drive the locking plate 27 to move through the vertical plate. Therefore, the locking groove 28 can move to the inner side wall of the locking groove 28 and press against the locking post 23. The friction provided by the pressing force between the locking post 23 and the locking groove 28 restricts the movement of the locking post 23, thereby achieving the purpose of locking the locking post 23.

[0035] Furthermore, such as Figure 5 As shown, the opening section of the locking groove 28 is a regular hexagon, and the corresponding section of the locking pin 23 is also a regular hexagon. This allows the locking groove 28 to obtain sufficient pressure to lock the locking pin 23 by means of conical contact when it shifts.

[0036] Furthermore, such as Figure 3 As shown, a pressure rod 26 is installed inside the sliding limit groove 25 located on the rear side. The pressure rod 26 is located inside the reset spring, and a pressure gauge 4 is installed on the upper end of the pressure rod 11. The pressure rod 26 corresponds to the pressure gauge 4. The pressure feedback from the locking pin 23 is obtained by the displacement of the positioning pin 24, which drives the displacement of the pressure rod 26. The pressure rod 26 is fed back to trigger the pressure gauge 4, thereby feeding back the pressure of the locking pin 23 onto the pressure gauge 4.

[0037] Furthermore, such as Figure 5 As shown, the locking pin 23 is slidably connected to the pressure seat 21, and the upper end of the locking pin 23 is connected to the pressure seat 21 through a pressure spring. The five locking pins 23 are independently controlled, so they can adapt to and cooperate with the TV frame.

[0038] Furthermore, such as Figure 8 As shown, the inner cylinder 32 is connected to the handle 35 by a thread, the locking block 33 is slidably connected to the inner cylinder 32, and the outer ring 31 is connected to the rocker arm 15 by welding. The outer side of the locking block 33 is formed with friction texture. The inner cylinder 32 is used to fix the circumferential displacement of the locking block 33, so that when the locking block 33 fixes the outer ring 31, the relative fixation between the inner cylinder 32 and the outer ring 31 will not loosen.

[0039] Furthermore, such as Figure 5 As shown, the telescopic rod 34 has a conical surface on the side corresponding to the locking block 33. The telescopic rod 34 is slidably connected to the inner cylinder 32. The telescopic rod 34 is squeezed outward by the button 36, thereby quickly fixing the locking block 33 and the outer ring 31.

[0040] In summary, after fixing the TV frame to the tabletop and aligning it with the standard lines, press down the devices at the four corners of the tabletop. Using the pressing bracket 14, the pressure rod 11 is driven down by the rocker arm 15. At this point, the locking pins 23 begin to contact the outer contour of the TV frame. Once the locking pins 23 contact the outer contour, they begin to retract into the fixing block 22, allowing the bottom surface of the locking pins 23 to fit against the outer contour. As the pressure rod 11 continues to press down, the locking pins 23 receive sufficient pressure, causing the pressure base 21 and the fixing block 22 to retract into the pressure rod 11. When block 22 begins to retract, positioning post 24 slides within sliding limit groove 25, and fixed block 22 is pulled backward. At the same time, because positioning post 24 is displaced on sliding limit groove 25, positioning post 24 is squeezed by the inclined surface within sliding limit groove 25. Positioning post 24 causes locking plate 27 to shift, and locking groove 28 locks locking post 23. At this time, the locked locking post 23 is subjected to a pulling force away from the center of the TV frame. The TV frame is locked and pulled outward by locking post 23 to ensure the stability of the TV frame and facilitate subsequent processing of the TV frame.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
