Description

Technical Field

[0001] The utility model relates to the technical field of servo presses, and specifically provides a multi-specification supporting head for a servo press. Background Art

[0002] The core shaft assembly of the current electric steering column assembly has materials in various states. During press assembly, different servo presses are usually used to meet product design requirements. However, this method requires a high installation space for the servo press, high press procurement costs, and complex press assembly process. Therefore, a servo press with multiple specifications of support heads and press heads is required.

[0003] Current servo presses with multiple sizes of support heads are mounted on a slide. A translation cylinder drives the slide, thereby moving the support heads of different sizes to the press-fitting position, thus switching the support heads. However, the slide uses a single rail, which reduces stability when supporting the upper support head, making it prone to damage and difficult to repair. The position of the support head perpendicular to the rail cannot be adjusted, making it difficult to ensure that the support head is coaxial with the upper tooling. Furthermore, the support head lacks a positioning or fixing structure, making it easy for the slide to slip during press-fitting, causing the support head to move and damage the workpiece. Utility Model Content

[0004] In order to solve the problem that the multi-specification support head in the prior art has low structural stability and is difficult to maintain, the utility model provides a multi-specification support head for a servo press, which is provided with a slide with slots; in order to solve the problem that the position of the support head in the prior art cannot be effectively adjusted, the multi-specification support head for a servo press provided by the utility model is provided with an adjustment component; in order to solve the problem that the support head is easy to move during press assembly in the prior art, the multi-specification support head for a servo press provided by the utility model is provided with a positioning component.

[0005] The specific solutions of the present utility model are as follows.

[0006] A multi-specification support head for a servo press includes a slide and a rail plate, two inner slide rails are arranged in parallel on the upper surface of the rail plate, and an outer slide rail is correspondingly arranged at the bottom of the slide, and the slide and the rail plate are slidably connected through the slide rails; the slide is provided with two slots parallel to the direction of the slide rails, the slots are aligned with the inner slide rails, and the outer slide rail is located at the extension of the slots; a plurality of support heads are arranged on the slide.

[0007] The slide is located above the rail plate, with outer slide rails symmetrically arranged on both sides of the slide's central axis, and inner slide rails symmetrically arranged on both sides of the rail plate's central axis. The rail plate is fixed to the servo press. When the slide slides relative to the rail plate via the slide rails, the support head arranged on the slide moves relative to the rail plate.

The multi-specification support head for a servo press of the present invention comprises a slide 1 and a rail plate 2. Both the slide 1 and the rail plate 2 are rectangular plate-like structures. The slide 1 is located directly above the rail plate 2. The slide 1 and the rail plate 2 are slidably connected via a slide rail 3. The length of the slide 1 is less than the length of the rail plate 2, so that the slide 1 can slide on the rail plate 2. The slide rail 3 comprises an inner slide rail 301 and an outer slide rail 302 that are adapted to each other. The inner slide rail 301 is provided with two, which are arranged in parallel on the upper surface of the rail plate 2 and are located on both sides of the central axis of the rail plate 2; the outer slide rail 302 is provided at the bottom of the slide 1 and is located on both sides of the central axis of the slide 1. The slide 1 is provided with two slots 101 parallel to the slide rail 3. The slots 101 are aligned with the inner slide rail 301. The outer slide rail 302 is located at the extension of the slots 101. The outer slide rail 302 is divided into four sections, which are located at the head and tail ends of the two slots 101 respectively, and slide in cooperation with the two inner slide rails 301.

[0038] Two support heads 4 are provided above the slide 1, namely a first support head 401 and a second support head 402. The first support head 401 and the second support head 402 are symmetrically arranged on the slide 1, are columnar, and have different specifications.

The first support head 401 is located at the head end of the crossbeam 102, and the second support head 402 is located at the tail end of the crossbeam 102.

[0039] When the slide 1 slides relative to the rail plate 2 via the slide rail 3, the support head 4 provided on the slide 1 moves relative to the rail plate 2. The utility model uses the same press machine to switch between support heads 4 of different specifications via the slide 1 to accommodate the design requirements of various workpieces, thereby reducing the working space, reducing operator fatigue, and improving production efficiency. The slide 1 is also provided with a slotted hole 101, which reduces the inertia of the slide 1 during sliding, making it easier to control the position of the slide 1.

[0040] The utility model provides a multi-specification support head for a servo press, and is further provided with an adjustment assembly 5, which includes an adjustment plate 501, an adjustment bolt 502, and an adjustment block 503.

An adjustment block 503 is fixedly provided at a corresponding position on the side of the slide 1, and the adjustment bolt 502 passes through the adjustment block 503. The first support head 401 is aligned with the upper tooling. By rotating the adjusting bolt 502, the adjusting component 5 below the second support head 402 is adjusted to fine-tune the position of the second support head 402, that is, the position of the second support head 402 perpendicular to the direction of the slide rail 3 can be adjusted to align with the first support head 401, that is, align with the upper tooling, so that the second support head 402 and the upper tooling are in a coaxial position, thereby improving the accuracy of the press-fitting.

[0041] The utility model provides a multi-specification support head for a servo press, and a buffer blocker 6 is also provided. There are two groups of buffer blocks 6, which are respectively located at the head end and the tail end of the rail plate 2. The buffer blocker 6 includes a baffle 601, a blocking bolt 602, a block 603 and a groove 604 on the block 603. The baffle 601 is fixedly mounted on the rail plate 2 by screws, is arranged vertically with the rail plate 2, and is located in the middle position of the two ends of the rail plate 2. Two blocking bolts 602 are also provided on each baffle 601. The height of the blocking bolt 602 is the same as the height of the slide 1, that is, the blocking bolt 602 is aligned with the slide 1, and the blocking bolt 602 is adjustable on the baffle 601. The two blocks 603 are respectively fixedly mounted at the head end and the tail end of the slide 1. Two grooves 604 are provided on the block 603, and the grooves 604 are aligned with the blocking bolt 602. When the slide 1 slides to one end of the track plate 2, the buffer stopper 6 limits the slide 1 to prevent it from derailing due to excessive inertial sliding distance. The pre-adjusted position of the blocking bolt 602 ensures that the support head 4 is precisely aligned with the upper tooling. Stoppers 603 are provided at both ends of the slide 1 to act as buffers during the process of limiting the slide 1 and reduce the risk of damage to the slide 1.

[0042] The multi-specification support head of a servo press of the present invention is further provided with a positioning assembly 7, which includes a positioning pin 701 and a positioning hole 702. The positioning assembly 7 includes at least two positioning pins 701 for positioning the slide 1, and a plurality of positioning holes 702 that are adapted to the positioning pins 701 are evenly provided on the inner slide rail 301. The positioning pins 701 pass through the slots 101 on the slide 1 and are embedded in the positioning holes 702 on the inner slide rail 301. The two positioning pins 701 are respectively located at the head end and the tail end of any slot 101. After adjusting the position of the slide 1, the position of the slide 1 is positioned by the positioning assembly 7, thereby fixing the position of the support head 4 during the press-fitting assembly process, thereby improving the reliability of the press-fitting.

[0043] In a preferred embodiment of the present invention, four positioning pins 701 are provided. A positioning pin 701 is provided at both ends of the two slots 101, which improves the reliability of positioning, ensures the force balance of the slide rail 3, and reduces the risk of damage to the slide rail 3.

[0044] The rail plate 2 is also fixedly connected to a cylinder 8 , which includes a piston rod 801 . The piston rod 801 of the cylinder 8 is connected to the slide 1 , and the piston rod 801 is parallel to the slide rail 3 along the moving direction of the cylinder 8 .

[0045] The present invention controls the position of the slide 1 by controlling the air cylinder 8, thereby switching the support head 4. When the first support head 401 is used, the piston rod 801 of the air cylinder 8 is retracted, and the slide 1 moves to the rear end above the track plate 2. The buffer stopper 6 at the rear end of the track plate 2 limits and blocks the slide 1, so that the first support head 401 is aligned with the upper tooling; when the second support head 402 is used, the piston rod 801 of the air cylinder 8 is extended, and the slide 1 moves to the front end above the track plate 2. The buffer stopper 6 at the front end of the track plate 2 limits and blocks the slide 1, so that the second support head 402 is aligned with the upper tooling.

[0046] like Figure 2 Shown is a schematic diagram of the structure of the servo press of the present invention, as shown in FIG. Figure 3 Shown is the main view of the servo press of the present invention, as shown in FIG. Figure 4 The figure shows a side view of the servo press of the present invention. The rail plate 2 has threaded holes and is fixed to the servo press via bolts. The slide 1 slides relative to the rail plate 2, meaning that the slide 1 slides relative to the servo press. A press head of varying sizes is positioned above the support head 4, which cooperates with the press head to press the workpiece.

[0047] The working process of the multi-specification support head of the servo press of the utility model is as follows.

[0048] Before the press-fitting work begins, first rotate the adjusting bolt 502 to align the second support head 402 with the upper tooling, that is, the second support head 402 is in a coaxial position with the upper pressure head. At the same time, the second support head 402 is also aligned with the first support head 401. By rotating the adjusting bolt 502, the position of the second support head 402 perpendicular to the direction of the slide rail 3 is fine-tuned to make the relative position of the press-fitting structure more accurate, thereby increasing the reliability of the press-fitted workpiece. Then adjust the blocking bolts 602 in the buffer blocker 6 at both ends of the track plate 2 so that when the slide 1 slides to the front end of the track plate 2, the second support head 402 is directly below the upper pressure head, and the second support head 402 is in a coaxial position with the upper pressure head. When the slide 1 slides to the rear end of the track plate 2, the first support head 401 is directly below the upper pressure head, and the first support head 401 is in a coaxial position with the upper pressure head. By adjusting the blocking bolt 602 in the buffer blocker 6, when the first support head 401 and the second support head 402 are located below the pressing head, their positions along the slide rail 3 are more precise, further increasing the reliability of the press-fit workpiece.

[0049] During the press-fitting process, the workpiece 9 is mounted on the top ends of the first support head 401 and the second support head 402 .

[0050] If you want to switch to the first support head 401, the piston rod 801 of the cylinder 8 retracts, and the slide 1 slides to the tail end above the rail plate 2. The blocking bolt 602 of the buffer blocker 6 at the tail end of the rail plate 2 presses against the groove 604 of the block 603, limiting and blocking the slide 1 so that the first support head 401 is aligned with the upper pressure head, and the positioning pins 701 are inserted at the head and tail ends of the two slots 101 of the slide 1. The positioning pins 701 are embedded in the positioning holes 702 on the inner slide rail 301 below the slots 101, thereby positioning the slide 1 and the first support head 401 and the second support head 402 on the slide 1. Finally, the first support head 401 cooperates with the upper pressure head to realize the press-fitting of the workpiece.

[0051] If you want to switch to the second support head 402, the piston rod 801 of the cylinder 8 is extended, and the slide 1 slides to the head end above the rail plate 2. The blocking bolt 602 of the buffer blocker 6 at the head end of the rail plate 2 is pressed against the groove 604 of the block 603, limiting and blocking the slide 1 so that the second support head 402 is aligned with the upper pressure head, and the positioning pins 701 are inserted at the head and tail ends of the two slots 101 of the slide 1. The positioning pins 701 are embedded in the positioning holes 702 on the inner slide rail 301 below the slots 101, thereby positioning the slide 1 and the first support head 401 and the second support head 402 on the slide 1. Finally, the second support head 402 cooperates with the upper pressure head to realize the press-fitting of the workpiece.

[0052] The extension and retraction of the piston rod 801 of the cylinder 8 is controlled electrically. It is only necessary to press the start button at the beginning of the press fitting to automatically control the extension and retraction of the piston rod 801 of the cylinder 8.

[0053] The utility model has high compatibility and can use the same press to switch support heads 4 of different specifications through the slide to be compatible with the design requirements of multiple materials, reducing the working space, reducing the fatigue of the operator, and improving production efficiency; a slide 1 with a slot hole 101 is also provided, which reduces the weight of the slide 1, thereby reducing the inertia of the slide 1 when sliding, and is easier to control the position where the slide 1 stops after sliding; the position of the slot hole 101 is opposite to the slide rail 3, which is convenient for maintenance. When the slide rail 3 is damaged, the slide rail 3 can be directly repaired through the slot hole 101 without disassembling any structure. The support head 4 is located at both ends of the beam 102, that is, the middle position of the slide rail 3. The structure is more balanced and stable, not easy to be damaged, and reduces loss.

[0054] The present invention is also provided with an adjustment component 5, which can adjust the position of the support head 4 perpendicular to the direction of the slide rail 3, so that when the support head 4 is aligned with the upper tooling, the support head 4 and the upper tooling are in a coaxial position, thereby improving the accuracy of press-fitting; the present invention is also provided with a positioning component 7, after adjusting the position of the slide 1, the position of the slide 1 is positioned by the positioning component 7, thereby fixing the position of the support head 4 during the press-fitting assembly process, avoiding damage to the workpiece caused by the movement of the support head 4 during the press-fitting process, and improving the reliability of press-fitting.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural transformation made to the above embodiment based on the technical essence of the present invention still fall within the scope of protection of the technical solution of the present invention.
