Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a screw fastening machine with an adjustable feeder height. Background Technology

[0002] The existing screw fastening machine's feeding device structure mostly consists of two plates and four support pillars. When it is necessary to adjust the feeding device to different heights, the height cannot be adjusted directly, and the support pillars need to be replaced manually. At the same time, there are many parts, resulting in high processing costs. In addition, the existing screw fastening structure requires a lower limit block to adjust the screw fastening depth. Furthermore, the cylinder itself does not have a buffer, and a hydraulic buffer must be added to achieve a buffering effect. This results in more parts, a heavier overall weight of the hanging parts, and consequently, a slower overall machine efficiency. Utility Model Content

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1 to 4As shown, this utility model provides a screw fastening machine with an adjustable feeder height. In one embodiment, it includes...

[0026] The work frame includes two first columns 1; the two first columns 1 are arranged in parallel and spaced apart, and a first crossbeam 2 is connected between the upper parts of the two first columns 1.

[0027] The screw-locking device 3 includes an X-axis translation mechanism 31 mounted on the first crossbeam 2, a first translation seat 32 connected to the X-axis translation mechanism 31, a Z-axis lifting mechanism 33 mounted on the first translation seat 32, and a mounting plate 34 connected to the Z-axis lifting mechanism 33; the mounting plate 34 is also equipped with a screw-locking mechanism 35.

[0028] The workbench 4 is installed between the two first columns 1 and below the first crossbeam 2; the workbench 4 is also equipped with a Y-axis translation mechanism 5, and the Y-axis translation mechanism 5 is also driven to connect a first sliding plate 51 for carrying products.

[0029] A feeding device 6 is arranged on one side of the Y-axis translation mechanism 5. The feeding device 6 includes a fixed base plate 61, an adjustable base plate 62, and a screw feeder 63. The fixed base plate 61 is installed on the workbench 4, and a fixed side plate 64 is connected to each of the top two ends of the fixed base plate 61. Several first fixing holes are spaced apart on one side of the fixed side plate 64 in the vertical direction. The adjustable base plate 62 is connected between the two fixed side plates 64, and several second fixing holes are spaced apart on both sides in the length direction. The screw feeder 63 is installed on the adjustable base plate 62.

[0030] Continue to refer to Figures 1 to 4 As shown, in this embodiment, the original method of fixing the height using a support column is replaced with an aluminum plate and multiple sets of through holes (after adjusting the screw feeder 63 to a suitable position, aligning the second fixing hole with the corresponding first fixing hole, and then tightening the screw to complete the installation, which is simple and convenient). This allows for free adjustment of the height of the screw feeder 63. Simultaneously, the original two side fixing plates are removed, allowing the two height-adjusting fixing side plates 64 to limit the two sides of the screw feeder 63. Multiple sets of holes are drilled on the adjusting base plate 62 and the fixing side plates 64, allowing for different combinations to meet the needs of different screw-locking machine models. Furthermore, a limiting block 65 is installed at each end of the top of the adjusting base plate 62, and the screw feeder 63 is positioned between the two limiting blocks 65. The limiting blocks 65 have oblong through holes, whose positions are adjustable, allowing for limiting the two ends of the screw feeder 63 (in this embodiment, an existing model of screw feeder 63 can be used) to ensure its stable installation.

[0031] In one embodiment, a first linear guide 341 is arranged vertically on one side of the mounting plate 34; the screw-locking mechanism 35 includes a linear guide slider, a first sliding seat 352, an electric screwdriver 353, a screwdriver bit 354, and a pressing and pushing mechanism 36; the linear guide slider is slidably arranged on the first linear guide 341; the first sliding seat 352 includes a connecting vertical plate mounted on the linear guide slider, and a connecting horizontal plate connected to the lower part of one side of the connecting vertical plate; the connecting horizontal plate has a clearance through hole, and the electric screwdriver 353 is mounted on the connecting horizontal plate. On the mounting plate 34, the output shaft of the electric screwdriver 353 passes through the clearance hole; a fixed horizontal plate 355 is also connected to one end of the first linear guide 341 on one side of the mounting plate 34, and a suction head 351 is also installed at the bottom of the fixed horizontal plate 355; one end of the screwdriver bit 354 is connected to the output shaft of the electric screwdriver 353, and the other end of the screwdriver bit 354 moves through the fixed horizontal plate 355 and is inserted into the suction head 351; the pressing and pushing mechanism 36 is mounted on the mounting plate 34 and connected to the connecting horizontal plate.

[0032] The pressing and pushing mechanism 36 includes a first fixing block 361, a pen-shaped cylinder 362, a pressing rod 363, and a pressing connecting block 364. The first fixing block 361 is connected to the upper part of one side of the mounting plate 34, and the pen-shaped cylinder 362 is mounted on the first fixing block 361. The pressing connecting block 364 is connected to one side of the connecting horizontal plate. One end of the pressing rod 363 is connected to the output shaft of the pen-shaped cylinder 362, and the other end of the pressing rod 363 is connected to the pressing connecting block 364.

[0033] In this embodiment, the pen-shaped cylinder 362 is an adjustable stroke cylinder with air buffer to save some structural components. Specifically, the lower position is achieved by adjusting the limit of the pen-shaped cylinder 362 (conventionally, this is achieved by a limit block and a screw). Here, the limit block and screw are saved. At the same time, the hydraulic buffer for the upper position can also be saved by the air buffer of the cylinder.

[0034] Meanwhile, one end of the pressing rod 363 is connected to a first limiting block 365, and the output shaft of the pen-shaped cylinder 362 is connected to the first limiting block 365; the other end of the pressing rod 363 is arranged to move through the pressing connecting block 364, and the other end of the pressing rod 363 is also connected to a second limiting block 366; a first spring 367 is also sleeved on the pressing rod 363, and the two ends of the first spring 367 abut against the bottom of the first limiting block 365 and the top of the pressing connecting block 364, respectively.

[0035] By adding a spring buffer structure, the machine can cope with the downward pressure of different screws. The force of the cylinder can be fixed. When the force of the cylinder is greater than the downward pressure, the first spring 367 is compressed. When the screw feed speed is faster than the downward pressure of the pen-shaped cylinder 362, the first spring 367 returns to its original position. The first spring 367 can respond accurately in real time to these two actions and can repeat the action multiple times. At the same time, without affecting stability, the mounting plate 34 has also been made lighter (the mounting plate 34 has multiple hollow holes). Overall, the total weight is reduced by 25%, which greatly improves the machine efficiency.

[0036] In addition, a rail clamping block 369 is installed on the first rail 341, and the rail clamping block 369 is located above the rail slider; one end of the first fixing block 361 is connected to the rail clamping block 369. The upper position of the cylinder is changed by adjusting the rail clamping block 369 to accommodate different lengths of screwdriver bits 354 and suction heads 351. At the same time, a first mounting hole is provided on the fixing plate 355, and a connecting sleeve 368 is installed in the first mounting hole; the suction head 351 is installed on the connecting sleeve 368; the other end of the screwdriver bit 354 moves through the connecting sleeve 368 and is inserted into the suction head 351. The screwdriver bit 354 can move up and down and rotate relative to the connecting sleeve 368 to perform screw-locking action. The top of the second limiting block 366 is also provided with a buffer pad, which can buffer the downward pressure applied by the first spring 367 to the lower connecting block 364 when the first spring 367 returns to its original position.

[0037] In one embodiment, the X-axis translation mechanism 31, the Y-axis translation mechanism 5, and the Z-axis lifting mechanism 33 adopt a closed-loop stepper drive with a synchronous belt (see the description of the Z-axis lifting mechanism 33 below for details). The Z-axis lifting mechanism 33 includes a first motor, a driving wheel, a driven wheel, a synchronous belt, a first slider, and a first connecting seat. A first cavity is provided on one side of the first translation seat 32. The first motor is installed on the upper part of the other side of the first translation seat 32, and the output shaft of the first motor is inserted into the first cavity. The driving wheel is installed on the output shaft of the first motor, and the driven wheel is installed in the lower part of the first cavity. The synchronous belt is wound between the driving wheel and the driven wheel. A guide rail is arranged on each side of the first cavity in the vertical direction, and the first slider is slidably arranged on the guide rail. The first connecting seat is installed on the first slider, and a fixing clamp is also installed in the first connecting seat. The synchronous belt passes through the first connecting seat, and one side of the synchronous belt is connected to the fixing clamp. The mounting plate 34 is installed on the first connecting seat.

[0038] The fixing clamp has a clamping groove, and one side of the timing belt is connected to the fixing clamp through the clamping groove. Driven by the first motor, the first connecting seat can be moved and the mounting plate 34 can be moved up and down via the driving wheel, timing belt, and driven wheel, so that the electric screwdriver 353 can tighten screws on the product. At the same time, in order to improve the safety of the operation of the electric screwdriver 353, slotted photoelectric switches are also installed in the upper and lower parts of the first cavity, and a sensing plate that works with the slotted photoelectric switches is also installed on the first connecting seat.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
