Description

Technical Field

[0001] The invention belongs to the technical field of workpiece clamping tools, and in particular relates to a special-shaped workpiece auxiliary clamping device for manufacturing mobile phone parts. Background Art

[0002] Auxiliary clamping devices play a vital role in the manufacturing industry, especially when processing special-shaped workpieces. These devices are usually designed to fix and support the workpiece to ensure stability, precision and safety during the processing. The main function is to ensure that the workpiece maintains a fixed position and direction during the processing, prevent processing errors or damage caused by movement or distortion of the workpiece, and provide support and stability so that the processing tool can accurately align with the specific part of the workpiece for processing, ensuring processing accuracy and surface quality. According to the shape, size and processing requirements of different workpieces, the design of auxiliary clamping devices can be diversified, including various fixtures, chucks, fixture components, etc. The design and selection of auxiliary clamping devices directly affect the efficiency of the entire processing process and the quality of the finished product. Therefore, in the engineering design and manufacturing process, there are strict requirements and specifications for its functions and performance requirements.

[0003] Mobile phone parts are delicate workpieces that require greater care during manufacturing to prevent damage to the parts. Existing special-shaped workpiece auxiliary clamping devices for mobile phone parts manufacturing usually use the state of squeezing both ends for clamping during use, which can easily cause damage to the mobile phone workpiece. In addition, during the fastening process of different workpieces, the protruding positions at both ends are usually used as force points, resulting in uneven force on the special-shaped workpiece, which can easily cause damage to the mobile phone parts. In addition, the clamping method of mobile phone parts is relatively single during the production and manufacturing process, and most mobile phone parts have different workpiece shapes, resulting in a large number of clamping tools and complicated costs, thereby increasing the factory processing cost. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an auxiliary clamping device for special-shaped workpieces used in the manufacture of mobile phone parts.

[0005] The technical solution adopted to solve the above technical problems is: to provide a special-shaped workpiece auxiliary clamping device for manufacturing mobile phone parts, comprising a bottom plate, a circular frame is fixedly connected to the center of the top of the bottom plate, a first circular ring is rotatably connected to the bottom of the outer wall of the circular frame, a connecting column is fixedly connected to the top of the first circular ring, and a second circular ring is fixedly connected to the top of the connecting column; A control mechanism is installed at the front end of the top of the bottom plate, a driving mechanism is installed at the top of the second ring, and a plurality of adsorption mechanisms are installed at the bottom of the driving mechanism; A turntable is rotatably connected to the center of the top of the bottom plate, and a suction mechanism is installed on the top of the turntable.

[0006] Furthermore, the control mechanism includes two supports fixedly connected to the front end of the top of the base plate, one side of one of the supports is fixedly connected to a first motor, an output end of the first motor is fixedly connected to a worm, and an outer wall of the first circular ring is fixedly connected to a plurality of teeth, and the plurality of teeth are all engaged with the worm.

[0007] Through the above technical scheme, when in use, when mobile phone parts are manufactured, after the special-shaped workpiece is placed on the device, the control mechanism is used to adjust the device to the specifications and sizes required by different special-shaped workpieces, thereby making the device more applicable when used. Specifically, when a sheet-like mobile phone part is placed, the worm can be driven to rotate by a first motor on one side of one of the supports. Since multiple teeth are engaged with the worm, and the first ring and the second ring are connected by a connecting column, the second ring can be rotated, so that the clamp can clamp the sheet-like mobile phone part around according to the size of the sheet-like mobile phone part, which is convenient for processing and manufacturing. At the same time, for columnar mobile phone parts, they can converge to the middle according to their diameter until the clamping tool can fit along the outer wall of the columnar mobile phone part to achieve clamping, thereby greatly improving the processing effect of the clamping device.

[0008] Furthermore, the driving mechanism includes a first support frame fixedly connected to the front end of the top of the second circular ring, a rectangular frame is fixedly connected to the inner wall of the first support frame, a first limiting groove is opened on the inner wall of the first support frame, a support plate is slidably connected inside the first limiting groove, the front end of the support plate is fixedly connected to the second motor, and the output end of the second motor is fixedly connected to the driving shaft, the top of the circular frame is fixedly connected to the second support frame, a second limiting groove is opened inside the second support frame, a limiting block is slidably connected inside the second limiting groove, two first guide rods are fixedly connected to the bottom of the limiting block, the outer walls of the two first guide rods are both provided with a first spring, two driving shafts are rotatably connected between the support plate and the limiting block, the limiting block is movably connected to the driving shaft, and the outer walls of the two first guide rods are movably connected to the second support frame, and the driving mechanism is provided in plurality, and the other two driving mechanisms are arranged in opposite states.

[0009] Through the above technical scheme, when in use, with the adjustment of the control mechanism, the driving mechanism can select different clamping widths according to the workpieces with different shapes, and can make corresponding adjustments in time, so as to facilitate the smooth progress of the clamping process, and under the symmetrical arrangement of the driving mechanism, not only can the workpieces with different shapes be clamped up and down, but also the workpieces can be clamped in the center, thereby improving the diversity of the clamping tools. Specifically, with the rotation of the second ring, the first support frame at the front end of the top of the second ring will rotate, and the second support frame located on the top of the circular frame will remain stationary. Similarly, multiple control mechanisms move synchronously, and when they move to the same In the case of the same size, stop the movement and put the mobile phone parts into the device. When the mobile phone parts are sheet-shaped, put the parts between multiple control mechanisms and adopt an upper and lower clamping method. Before clamping, the first spring will be compressed upward or downward synchronously. At this time, the sheet parts are clamped by the clamping device. When the mobile phone parts are columnar, as the second ring rotates, multiple drive shafts will shrink inward at the same time until the columnar parts are clamped in the central position. Then start the second motor at the front end of the support plate to drive the drive shaft to rotate, so that the clamping device can be adjusted until it reaches a clamping state, thereby maintaining the clamping of the special-shaped workpiece.

[0010] Furthermore, the adsorption mechanism includes a plurality of gears fixedly connected to the outer walls of the two driving shafts, the outer walls of the plurality of gears are meshed with chains, the inner wall of the support plate is rotatably connected to a rotating connecting ring, one side of the rotating connecting ring is fixedly connected to a plurality of first connecting tubes, the plurality of chain connections are fixedly connected to support tubes, the outer walls of the plurality of support tubes are fixedly connected to a plurality of suction cups, a third limiting groove is provided on the inner wall of the rectangular frame, a limiting plate is slidably connected to the inside of the third limiting groove, two second guide rods are fixedly connected to the top of the limiting plate, the outer walls of the two second guide rods are provided with a second spring, one end of the plurality of first connecting tubes are respectively fixedly connected to the corresponding support tubes, the two second guide rods pass through the first support frame, and the adsorption mechanism is arranged in positive and negative symmetry.

[0011] Through the above technical scheme, when in use, as the sheet or columnar parts are clamped in the device through the driving mechanism, with the assistance of the adsorption mechanism, the sheet can be protected when it is put in, avoiding damage to the parts caused by hardware clamping, and at the same time, the adsorption mechanism can be used to adsorb the surface to ensure that the parts are stable. Specifically, when the mobile phone parts are sheet-shaped, multiple suction cups are used to provide relevant protection when they are put in and clamped. When the parts are put in, the second spring will be squeezed upward or downward to move upward or downward. At the same time, the support plate and the limit plate will move along the corresponding first limit groove or the third limit groove. When the mobile phone parts are columnar, as the driving shaft rotates, the chains of the outer walls of the multiple gears are driven to rotate, and when the support tube rotates, it drives the multiple first connecting tubes to rotate. Under the rotation connection of the rotating connecting ring, the rotation will not cause pipeline disorder. Then, the multiple suction cups are rotated to the inside so that the suction cups can be tightly attached to the outer wall of the columnar parts, thereby completing the clamping of the mobile phone parts.

Specifically, after adjustment according to the needs of the special-shaped workpiece, the exhaust fan is started at this time to adsorb and stick the workpiece through multiple suction cups, and the wind is sucked into the exhaust fan through multiple support tubes and multiple second connecting tubes, and then discharged from the outlet pipe, thereby ensuring the stability of the special-shaped parts on the device.

[0014] The beneficial effects of the present invention are as follows: (1) The present invention designs a control mechanism, a driving mechanism, an adsorption mechanism and a suction mechanism. When a special-shaped workpiece is placed in the device, it can be adjusted according to the shape of the workpiece, thereby improving the applicability of the device and providing certain convenience for the manufacture of mobile phone parts. At the same time, for the mobile phone parts that are easily damaged, a certain suction cup is used to assist in clamping and protect them, thereby greatly improving the safety of mobile phone parts manufacturing; (2) The present invention designs a control mechanism and a driving mechanism. After the special-shaped mobile phone parts are placed in the device, they can be clamped up and down or in the center according to the shape of the special-shaped workpiece, thereby greatly improving the applicability of the device; (3) The present invention designs an adsorption mechanism and a suction mechanism.

Specifically, when a sheet-like mobile phone part is placed, the worm 603 can be driven to rotate by the first motor 602 on one side of one of the supports 601. Since multiple teeth 604 are engaged with the worm 603, and the first ring 3 and the second ring 5 are connected by the connecting column 4, the second ring 5 can be rotated, so that the clamp can clamp the sheet-like mobile phone part around according to the size of the part, which is convenient for processing and manufacturing. At the same time, for columnar mobile phone parts, they can converge to the middle according to their diameter until the clamping tool can fit along the outer wall of the columnar mobile phone part to achieve clamping, thereby greatly improving the processing effect of the clamping device.

[0019] like Figure 6-Figure 9As shown, a driving mechanism 7 is installed on the top of the second ring 5, and the driving mechanism 7 includes a first support frame 701 fixedly connected to the front end of the top of the second ring 5, a rectangular frame 702 is fixedly connected to the inner wall of the first support frame 701, a first limiting groove 703 is opened on the inner wall of the first support frame 701, a support plate 704 is slidably connected inside the first limiting groove 703, a second motor 705 is fixedly connected to the front end of the support plate 704, and a driving shaft 706 is fixedly connected to the output end of the second motor 705, a second support frame 707 is fixedly connected to the top of the circular frame 2, and a second limiting groove 708 is opened inside the second support frame 707.

When in use, with the adjustment of the control mechanism 6, the driving mechanism 7 can move with the special-shaped tool Different clamping widths can be selected for each part, and corresponding adjustments can be made in time to facilitate the smooth progress of the clamping process. Under the symmetrical arrangement of the driving mechanism 7, not only can the heterogeneous workpieces be clamped up and down, but also the workpieces can be clamped in the center, thereby improving the diversity of the clamping tools. Specifically, as the second ring 5 rotates, the first support frame 701 at the front end of the top of the second ring 5 will rotate, and the second support frame 707 located on the top of the circular frame 2 remains stationary. Similarly, multiple control mechanisms 6 move synchronously, and when they move to the same size, they stop moving. At this time, the mobile phone parts are placed in In the device, when the mobile phone parts are sheet-like, the parts are placed between multiple control mechanisms 6, and an upper and lower clamping method is adopted. Before clamping, the first spring 711 will be compressed upward or downward synchronously, and the sheet-like parts are clamped by the clamping device. When the mobile phone parts are columnar, as the second ring 5 rotates, multiple drive shafts 706 will shrink inward at the same time until the columnar parts are clamped in the central position, and then the second motor 705 at the front end of the support plate 704 is started to drive the drive shaft 706 to rotate, so that the clamping device can be adjusted until it reaches a clamping state, thereby maintaining the clamping of the special-shaped workpiece.

When in use, as the sheet or columnar part is clamped in the device through the driving mechanism 7, In this case, with the help of the adsorption mechanism 8, the sheet-like object can be protected when it is put in, so as to avoid damage to the parts caused by hardware clamping. At the same time, the adsorption mechanism 8 can be used to adsorb the surface to ensure that the parts are stable. Specifically, when the mobile phone parts are sheet-like, multiple suction cups 806 are used to provide relevant protection when they are put in and clamped. When the parts are put in, the second spring 810 will be squeezed upward or downward to move upward or downward. At the same time, the support plate 704 and the limiting plate 808 will follow the corresponding first limiting groove 703 or the second limiting groove 704.

Since multiple teeth 604 are engaged with the worm 603, and the first ring 3 and the second ring 5 are connected by the connecting column 4, the second ring 5 can be rotated. As the second ring 5 rotates, the first support frame 701 at the front end of the top of the second ring 5 will rotate. At this time, the second support frame 707 located on the top of the circular frame 2 remains stationary. Similarly, multiple control mechanisms 6 move synchronously. When they move to the same size, they stop moving. At this time, the mobile phone part is placed in the device. When the mobile phone part is sheet-like, the part is placed between the multiple control mechanisms 6. At this time, an upper and lower clamping method is adopted. Before clamping, the first spring 711 will be compressed upward or downward synchronously. At this time, through multiple The suction cups 806 are used for relevant protection when they are put into the clamp, and when the mobile phone parts are columnar, as the second ring 5 rotates, the multiple drive shafts 706 will shrink inward at the same time, and as the drive shaft 706 rotates, the second motor 705 at the front end of the support plate 704 is then started to drive the drive shaft 706 to rotate, and the chain 802 on the outer wall of the multiple gears 801 is driven to rotate, and then the multiple suction cups 806 are rotated to the inside, so that the suction cups 806 can be tightly attached to the outer wall of the columnar parts, and the columnar parts are clamped by the clamping device. After adjustment according to the needs of the special-shaped workpiece, the exhaust fan 1003 is started at this time to adsorb and stick the workpiece through the multiple suction cups 806, and the wind is sucked into the exhaust fan 1003 through the multiple support tubes 805 and the multiple second connecting tubes 1001, and then discharged from the outlet pipe 1004, so that the working process of the entire device is completed.
