DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0030] See also Figures 1 to 4 The present application provides a technical solution: a front support and positioning mechanism for a bending machine, comprising a main body box 1, two connecting plates 2 are fixed on the right side of the main body box 1, a vertical moving component 300 is installed on the inner side of the main body box 1, a placement component that can be driven by the vertical moving component 300 for vertical adjustment is installed on the outer side of the main body box 1, and a lateral moving component 500 that can drive the main body box 1 for lateral adjustment is installed between the two connecting plates 2 on the side away from the main body box 1; through the coordinated use of the vertical moving component 300 on the inner side of the main body box 1 and the lateral moving component 500 on the outer side, the supporting structure can be adjusted horizontally more conveniently, flexibly and accurately, so that the accuracy of the lateral adjustment can be further improved, avoiding mistakes and errors due to the subjective operation and judgment of the operator, and at the same time improving the flexibility of operation, so that the practicality of the overall mechanism is effectively improved.

[0031] In this embodiment, the lateral movement assembly 500 is a structure for performing accurate lateral movement.

[0032] like Figure 2 , Figure 3 and Figure 4As shown, the lateral movement assembly 500 includes an installation box 501, a second screw rod 502 rotatably connected to the inner side of the installation box 501 through a bearing, two second guide rails 503 fixedly installed on the inner side of the installation box 501, a sliding seat 504 threadedly connected to the outer side of the second screw rod 502 and limited by the two second guide rails 503, a laser sensor 505 fixedly installed on the outer side of the sliding seat 504, a fixed box 506 fixed to the inner side of the installation box 501, a transmission rod 507 fixed to the end of the second screw rod 502 and passing through and extending to the interior of the fixed box 506, a driven bevel gear 508 sleeved on the outer side of the transmission rod 507, a second driving mechanism 509 fixedly installed on the inner side of the fixed box 506, an active bevel gear 510 fixedly installed on the output shaft of the second driving mechanism 509, and a photoelectric reflector 511 fixedly installed on the side of the installation box 501 close to the main box 1.

[0033] It should be noted that the end of the second screw rod 502 close to the fixed box 506 is rotatably connected to the outer side of the fixed box 506 through a bearing, and the two second guide rails 503 are symmetrically distributed up and down, so that the sliding seat 504 can move between the outer sides of the two second guide rails 503 under the action of the outer thread rotation thrust of the second screw rod 502.

[0034] In addition, the outer side of the sliding seat 504 is detachably connected to the two connecting plates 2 on the side away from the main box 1 through bolts, so that the sliding seat 504 can drive the two connecting plates 2 to move, thereby driving the main box 1 to move. The top and bottom of the installation box 501 are fixedly connected with docking plates with a plurality of through holes on the surface. The through holes can be used for bolts to pass through, so that the installation box 501 can be fixedly installed on the outside of the bending machine, thereby facilitating the position adjustment.

[0035] At the same time, the position of the laser sensor 505 corresponds to the position of the photoelectric reflector 511, and both are located between the connecting plate 2 and the opposite side of the installation box 501, so that the laser beam emitted by the laser sensor 505 can be received and reflected by the photoelectric reflector 511, thereby facilitating the determination of the current position data.

[0036] In addition, the outer side of the transmission rod 507 is rotatably connected to the two inner side walls of the fixed box 506 through two bearings, and the outer side of the active bevel gear 510 is meshed with the outer side of the driven bevel gear 508, so that the active bevel gear 510 can normally drive the driven bevel gear 508 to rotate and allow the transmission rod 507 to rotate stably.

[0037] In this embodiment, the vertical moving assembly 300 is a structure for performing accurate vertical movement.

[0038] like Figure 1As shown, the vertical moving assembly 300 includes a first screw rod 301 rotatably connected to the inner side of the main box 1 through a bearing, a first guide rail 302 fixedly installed on the inner side of the main box 1, an adjustment seat 303 threadedly connected to the outer side of the first screw rod 301 and limited by the first guide rail 302, a reducer 304 fixedly installed on the inner side of the main box 1, and a first driving mechanism 305 fixedly installed on the outer side of the main box 1 and with the output shaft fixedly connected to the input shaft of the reducer 304.

[0039] It should be noted that the placement component includes a fixing frame 401 fixed to the outside of the adjustment seat 303, and a support platform 402 fixedly installed on the top of the fixing frame 401. The support platform 402 is located above the main box 1. A connecting hole for the fixing frame 401 to slide is opened on the left side of the main box 1, so that the support platform 402 can move vertically in a straight line under the driving action of the fixing frame 401.

[0040] In addition, a partition plate is fixed on the inner side of the main box 1, and the bottom end of the first screw rod 301 is rotatably connected to the top of the partition plate through a bearing. The output shaft of the reducer 304 passes through the bottom of the partition plate and is fixedly connected to the bottom end of the first screw rod 301, so that the partition plate can provide support for the first screw rod 301, and at the same time, the first screw rod 301 can be driven by the reducer 304 to rotate.

[0041] At the same time, a position indicator for position monitoring is installed on the outside of the input shaft of the reducer 304. The position indicator uses the functions of an encoder and closed-loop control to enable the position indicator to control the input amount of the first drive mechanism 305 according to the actual number of rotations to achieve a precise control effect. In layman's terms, the position indicator can be set to a preset value by the user so that the input amount of the motor can drive the moving structure to that position.

[0042] The working principle of the above embodiment is:

[0043] When the aluminum foil sheet is bent, the sheet is placed on the top of the support platform 402, and the first driving mechanism 305 is started to drive the reducer 304 to rotate, so that the first screw rod 301 rotates, and under the limiting and guiding action of the first guide rail 302, the adjustment seat 303 can move vertically in a straight line, so as to complete the height adjustment of the sheet, and the second driving mechanism 509 is started to drive the active bevel gear 510 to rotate, so that the driven bevel gear 508 rotates and drives the transmission rod 507 to rotate, so that the second screw rod 502 rotates, and under the limiting guidance and support of the two second guide rails 503, the sliding seat 504 can be adjusted to move horizontally, and the actual adjustment distance can be accurately monitored under the cooperation between the laser sensor 505 and the photoelectric reflector 511, so as to realize the function of precise positioning, and complete the position adjustment and positioning of the aluminum foil sheet, so that it is convenient to perform accurate bending processing through the bending machine.

[0044] Compared with the prior art, the front support positioning mechanism of the bending machine can more conveniently, flexibly and accurately adjust the support structure horizontally through the cooperation between the vertical moving component 300 on the inside of the main box 1 and the lateral moving component 500 on the outside, so that the accuracy of the lateral adjustment can be further improved, avoiding mistakes and errors due to the subjective operation and judgment of the operator. At the same time, it also improves the flexibility of operation, effectively improves the practicality of the overall mechanism, and solves the problem that the operation method of the existing front supporting device when adjusting the workpiece position horizontally is very subjective and prone to large errors.

[0045] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
