Description

Technical Field

[0001] The utility model relates to the technical field of servo presses, and particularly relates to a feeding mechanism for a double-station servo press. Background Technique

[0002] In the electrical-related industries, many devices need to use metal casings. These casings are mostly composed of multiple components to form a casing that facilitates the installation of electrical components. Therefore, when assembling related casings, a servo press is required for non-rivet press riveting work to assemble the casings.

[0003] In the prior art, the casing that needs to be stamped and riveted is manually placed on the fixture in the double-station servo press. Then, by starting the servo motor, the fixture is driven to move longitudinally on the workbench of the servo press through a lead screw, so as to send the casing under the press riveting punch of the servo press to complete feeding. The punch is driven by a servo cylinder to press down to cooperate with the riveting die to perform non-rivet riveting on the connection part of the assembled casing, and complete the press riveting work. However, in use, due to the existence of various models of casings, the assembly positions of the components in the casings are different. When press riveting on both sides of the upper surface of the casing at different assembly positions, the press riveting positions are also different, and thus it cannot match the riveting die in the fixture. Furthermore, it is necessary to replace the fixture, and the applicability is poor. In addition, when the riveting die in the existing fixture is damaged, it is not easy to replace, which brings inconvenience to the production work. Therefore, there is room for improvement. Summary of the Utility Model

[0004] The utility model provides a feeding mechanism for a double-station servo press to solve the problems raised in the background technique.

[0005] To solve the above problems, the utility model provides a feeding mechanism for a double-station servo press, including a press body. In the middle of the workbench in the press body, a gantry is provided. Two groups of press riveting punches are movably arranged in the gantry, and each group of press riveting punches has two. Two structurally identical feeding mechanisms are symmetrically arranged under the gantry on the workbench, and the two feeding mechanisms match the two groups of press riveting punches. The feeding mechanism is composed of a guide rail group, a fixture, and a servo motor. The guide rail group is composed of two guide rails, and the two guide rails are symmetrically and fixedly installed on the workbench. A lead screw is arranged between the two guide rails in the guide rail group. The lead screw is rotatably installed on the workbench, and one end is arranged outside the workbench and is equipped with a flywheel. The fixture is composed of a fixing plate, a support frame, and a riveting template. The fixing plate is slidably connected to the two guide rails of the guide rail group, and the bottom is threadedly connected to the lead screw through a slider. The servo motor is fixedly installed under the workbench and is connected to the lead screw through a belt and the flywheel.

[0006] Preferably, the support frame in the fixture is installed on the fixed plate by bolts. There are two riveting templates, which are symmetrically installed on both sides of the support frame by bolts. A number of mounting holes are equidistantly arranged on both sides of the support frame in the fixed plate. A number of T-shaped mounting holes are equidistantly arranged in the riveting template, and a T-shaped female die column is sleeved in the T-shaped mounting hole.

[0007] Preferably, one side of the female die column is provided with a positioning section, and the T-shaped mounting hole is provided with a positioning surface matching the positioning section, and the positioning surface is located on the outer side of the riveting plate.

[0008] Preferably, a corner riveting template is installed at each of the four corners of the support frame, and a female die column is fixedly installed in the corner riveting template.

[0009] The beneficial effects of adopting the above technical solutions are as follows:

[0010] 1. The servo motor drives the threaded lead screw to rotate, thereby driving the fixed plate to move along the two guide rails in the guide rail group, so that the housing placed on the fixture is stably moved below the pressing riveting punch of the gantry. Through the movement of the fixture in the workbench and the movement of the pressing riveting punch in the gantry, the housing is quickly pressed and riveted. Since both the feeding mechanism and the pressing riveting punch are in two groups, the two groups work alternately, which can ensure the rhythm of the equipment operation and is convenient for the staff to operate.

[0011] 2. The housing can be placed through the support frame and the riveting female die in the fixture. Through the arrangement of a number of female die columns in the riveting female die, it is convenient for the pressing riveting punch to cooperate with the female die columns to form non-riveted riveting for the housing. And since the number of female die columns is several and equidistantly arranged in the riveting female die, it is convenient to carry out the pressing and riveting work on the connection parts of the housing at different positions on both sides of the housing, improving the applicability of the work.

[0012] 3. The riveting template is installed on both sides of the top of the support plate by bolts, which is convenient for the maintenance of the female die column and also convenient for the replacement of the riveting template.

[0013] 4. Through the arrangement of the corner riveting templates at the four corners of the support frame, it is convenient to carry out the pressing and riveting work on the lower edges of the four corners of the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Such as Figures 1-4, in this embodiment, a feeding mechanism for a double-station servo press includes a press body 1. In the middle of the workbench 11 in the press body 1, a gantry 12 is provided. Two groups of riveting punches 2 are movably arranged in the gantry 12, and each group of riveting punches 2 has two. On the workbench 11, two feeding mechanisms 3 with the same structure are symmetrically arranged below the gantry 12, and the two feeding mechanisms 3 are matched with the two groups of riveting punches 2. The feeding mechanism 3 is composed of a guide rail group 4, a fixture 5, and a servo motor 6. The guide rail group 4 is composed of two guide rails 41, and the two guide rails 41 are symmetrically and fixedly installed on the workbench 11. A lead screw 7 is arranged between the two guide rails 41 in the guide rail group 4. The lead screw 7 is rotatably installed on the workbench 11, and one end is arranged outside the workbench 11 and is equipped with a flywheel 71. The fixture 5 is composed of a fixing plate 51, a support frame 52, and a riveting template 53. The fixing plate 51 is slidably connected to the two guide rails 41 of the guide rail group 4, and the bottom is threadedly connected to the lead screw 7 through a slider 511. The servo motor 6 is fixedly installed below the workbench 11 and is connected to the lead screw 7 through a belt 61 in cooperation with the flywheel 71.

[0023] Through the above technical solution, when in use, an operator places two or more shells and components to be riveted into the fixture 5 of the feeding mechanism 3 in the press body 1. The shells and accessories are supported by the support frame 52 and the riveting template 53. Then, the shell is clamped from the outer side by a fixture to make it stable (the fixture is a pneumatic fixture arranged in the fixing plate and can abut against the outer surface of the shell to ensure its stability. Since the position of the fixture can be adjusted according to the position of the shell to be riveted, the fixture is not shown in the figure). Then, the servo motor 6 in the feeding mechanism 3 is started to drive the flywheel 71 to rotate through the belt 61, and then drive the lead screw 7 to rotate on the workbench 11. The lead screw 7 drives the slider 511 to drive the fixture 5 to move along the two guide rails 41 of the guide rail group 4 in the workbench 11, and send the shell to be riveted below the riveting punch 2. Through the lateral movement of the riveting punch 2 in the gantry 12 and the longitudinal movement of the fixture 5 in the workbench through the feeding mechanism 3, the connection of the shell can be accurately and quickly riveted. Since there are two groups of the feeding mechanism 3 and the riveting punches 2, the two groups can work alternately, ensuring the work efficiency and work rhythm, and facilitating the operation of the staff. Each group of riveting punches 2 has two, so that the two riveting punches 2 work simultaneously, which is convenient for synchronously riveting the upper surfaces on both sides of a shell, improving the riveting efficiency and ensuring the stability of the shell in the fixture 5 during riveting.

[0024] Preferably, the support frame 52 in the jig 5 is installed on the fixed plate 51 by bolts. There are two riveting templates 53, which are symmetrically installed on both side edges of the support frame 52 by bolts. A number of mounting holes 512 are equidistantly arranged on both sides of the support frame 52 in the fixed plate 51. A number of T-shaped mounting holes 531 are equidistantly arranged in the riveting template 53. A T-shaped female die column 54 is sleeved in the T-shaped mounting hole 531.

[0025] Through the above technical solution, the housing or the fitting is placed above the riveting template 53 in the jig 5. The housing and the fitting are abutted by the support frame 52 and the riveting template 53. The upper mouth of the female die column 54 installed in the outer T-shaped mounting hole 531 in the riveting template 53 abuts against the connection part of both side edges of the housing and the fitting. When the riveting punch 2 punches the connection part of the housing and the fitting, the housing and the fitting can be riveted without rivets in cooperation with the female die column 44. At the same time, since a number of female die columns 55 are installed in the riveting template 53, it is convenient to cooperate with the riveting punch 2 to carry out riveting on different positions of the housing and the fitting. Therefore, the applicability of the equipment is improved. Since the riveting template 53 is connected to the support frame 52 by bolts and the female die column 54 is sleeved in the T-shaped mounting hole 531, it is convenient to replace or maintain the female die column 54. The mounting holes 512 equidistantly arranged on both sides in the fixed plate 51 are used to install the pneumatic fixture thereon according to the actual situation, so as to clamp the housing to be riveted.

[0026] Preferably, a positioning section 541 is provided on one side of the female die column 54. A positioning surface 532 matching the positioning section 551 is provided in the T-shaped mounting hole 531, and the positioning surface 532 communicates with the outer side surface of the riveting plate 53.

[0027] Through the above technical solution, the positioning section 541 of the female die column 54 cooperates with the positioning surface 532 in the T-shaped mounting hole 531, so that the female die column 54 can be stably sleeved in the T-shaped mounting hole 531, and it is not easy to shake, ensuring the stability of the stamping work.

[0028] Preferably, corner riveting templates 55 are respectively provided at the four corners of the support frame 52, and a female die column 54 is fixedly installed in each corner riveting template 55.

[0029] Through the above technical solution, the corner riveting template 55 cooperates with the female die column 54, which is convenient for carrying out riveting work on the lower edge feet of the housing.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than limiting the technical solutions described in the present utility model; Therefore, although this specification has described the present utility model in detail with reference to the above various embodiments, however, those of ordinary skill in the art should understand that the present utility model can still be modified or equivalently replaced, and all technical solutions and their improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model; The technologies not detailed in the present utility model are implemented with the prior art.
