A press mounting structure with online float

Abstract

This invention relates to the field of disc pressing equipment and discloses an online floating press pressing structure, including a turntable with a tooling fixture for clamping products. A base is located on one side of the turntable, and a sliding block capable of floating up and down is connected to one side of the base via a sliding assembly. A press body is mounted on the sliding block, and a press head is connected to the output end of the press body. A protrusion is located on one side of the tooling fixture, and a hook plate is located on one side of the sliding block, below the protrusion. The floating assembly allows the press body and the sliding block to float up and down. When the press head presses down, the sliding block receives an upward reaction force and moves upward until the hook plate abuts against the bottom surface of the protrusion, hooking the sliding block with the tooling fixture and thus counteracting the pressure on the turntable. This structure effectively prevents turntable deformation, improves pressing accuracy, and increases turntable life.

Description

Technical Field

[0001] This invention relates to the field of disc pressing equipment, and more specifically to an online floating press pressing structure. Background Technology

[0002] Press fitting is a process that uses a press to apply pressure to precisely assemble parts together. During press fitting, by precisely controlling parameters such as the magnitude of the pressure, the speed of application, and the duration, it is ensured that the parts can fit together tightly and accurately. This process is often used in industries with high requirements for assembly precision, such as automobile manufacturing and machining.

[0003] The existing press-fitting structure uses a method of fixing the press and rigidly supporting the clamps and disc with metal materials, that is, using the rigidity of the metal materials to counteract the downward pressure of the press. In order to ensure that the disc can rotate normally, there is a certain gap between the support blocks. Therefore, the disc will deform during press-fitting, affecting the press-fitting accuracy, reducing the life of the turntable, and in severe cases, even causing the normal production of products to be disrupted, resulting in huge losses for enterprises. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide an online floating press pressing structure. The press can float up and down relative to the base through the floating component. When the press presses down, the slide will be subjected to an upward reaction force. Then, the hook plate on one side of the slide is hooked to the protrusion of the tooling fixture to offset the pressure on the turntable. This solves the problem that the pressure applied by the press to the tooling fixture and the product will eventually act on the turntable, causing the turntable to deform.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An online floating press pressing structure includes a turntable, on which a tooling fixture for clamping products is provided. A base is provided on one side of the turntable, and a slide block that can float up and down is connected to one side of the base via a sliding component. A press body is mounted on the slide block, and a pressure head that can press against the product is connected to the output end of the press body. An adjuster for adjusting the height of the slide block is also provided on one side of the base. One side of the tooling fixture is provided with a protrusion protruding from the outer circumferential surface of the turntable, and one side of the slide is provided with a hook plate, which is located below the protrusion; when the pressure head moves down and contacts the product, the hook plate moves up and abuts against the bottom surface of the protrusion.

[0006] Optionally, the sliding assembly includes a slide rail and a slider that are slidably connected. The slide rail is fixedly connected to the slide block, and the slider is fixedly connected to the base. The moving direction of the slide block is parallel to the moving direction of the pressure head.

[0007] Optionally, two slide rails are arranged opposite each other, and each slide rail is provided with at least two sliders.

[0008] Optionally, the base is further provided with a limiter for limiting the vertical floating range of the slide block, and the limiter is located between the two slide rails.

[0009] Optionally, the adjuster is located at the bottom of the slide, with one end of the adjuster connected to the slide and the other end connected to the base via a support block.

[0010] Optionally, the adjuster includes a first adjusting screw and a second adjusting screw disposed opposite to each other, the first adjusting screw being connected to the slide, the second adjusting screw being connected to the support block, and a spring being installed between the first adjusting screw and the second adjusting screw.

[0011] Optionally, the tooling fixture includes a support fixedly connected to the turntable, a support block for supporting the product is provided on the support, and a rotary clamping cylinder for fixing the product is provided on the outside of the support block.

[0012] Optionally, the protrusion and the bottom of the support are integrally formed, and the hook plate is integrally formed and connected to the bottom of the slide.

[0013] Beneficial effects

[0014] (1) In this invention, the press body and slide can float up and down by means of a floating component. When the press head is pressed down, the slide will be subjected to an upward reaction force and move upward until the hook plate abuts against the bottom surface of the protrusion, so that the slide is hooked with the tooling fixture, thereby offsetting the pressure on the turntable. This structure can solve the problem that the pressure applied by the press body to the tooling fixture and the product will eventually act on the turntable, causing the turntable to deform. It can effectively prevent the turntable from deforming, improve the pressing accuracy, and increase the turntable life.

[0015] (2) In this invention, the adjuster can not only provide support for the slide, but also adjust the position height of the slide relative to the base, so that when the structure is not in the press-fit state, there is a certain gap between the hook plate and the protrusion, so as to ensure that the turntable can rotate smoothly.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0018] Example 1

[0019] like Figures 1-5 As shown, an online floating press pressing structure includes a turntable 1, a tooling fixture 2, a base 3, a slide 4, a sliding assembly 5, a press body 6, and a press head 7. A divider 10 is provided at the bottom of the turntable 1 to ensure accurate rotation into position. Multiple tooling fixtures 2 are provided on the turntable 1 and arranged in a circular array around the axis of the turntable 1. Their function is to clamp and fix the product so that the press body 6 can drive the press head 7 to press it. The base 3 is fixedly installed on one side of the turntable 1. The slide 4 is slidably connected to the base 3 through the sliding assembly 5, allowing the slide 4 to float up and down relative to the base 3 under the action of the sliding assembly 5. The press body 6 is fixedly installed on the slide 4, and its output end is connected to the press head 7. The press body 6 can drive the press head 7 to press down, thereby performing a pressing operation on the product fixed on the tooling fixture 2.

[0020] As described above, a protrusion 21 protruding from the outer circumferential surface of the turntable 1 is provided on one side of the tooling fixture 2, and a hook plate 41 is provided on one side of the slide 4. The hook plate 41 is located below the protrusion 21 and is integrally formed and connected to the bottom of the slide 4 to ensure that the hook plate 41 and the slide 4 can move synchronously. When the pressure head 7 moves down and contacts the product, the hook plate 41 moves up and abuts against the bottom surface of the protrusion 21, so that the slide 4 and the tooling fixture 2 are hooked together.

[0021] Specifically, when the pressure head 7 descends and contacts the product, the product and the tooling fixture 2 are subjected to downward pressure. At this time, the slide 4 is subjected to an upward reaction force and tends to move upward. However, after the hook plate 41 moves upward with the slide 4 and contacts the protrusion 21, it gives the tooling fixture 2 an upward force, thereby balancing the downward pressure on the tooling fixture 2 and offsetting the pressure applied by the press body 6. This allows the turntable 1 to be unaffected by the pressure applied by the press body 6, effectively preventing the turntable 1 from deforming, improving the pressing accuracy, and increasing the life of the turntable 1.

[0022] As described above, the tooling fixture 2 includes a support fixedly connected to the turntable 1. The support is provided with a support block for supporting the product. A rotary clamping cylinder for fixing the product is provided on the outside of the support block. The protrusion 21 and the bottom of the support adopt an integral molding structure, that is, the protrusion 21 is the outward extension of the bottom of the support. Its function is to protrude from the turntable 1 so that when the slide 4 has an upward tendency, it can be hooked together with the support of the tooling fixture 2 through the hook plate 41.

[0023] When the product is installed on the tooling fixture 2, it is first placed on the support block for positioning, and then fixed by rotating the clamping cylinder to finally complete the product clamping, so that the press head 7 can move down for pressing operation.

[0024] Furthermore, the sliding assembly 5 includes a sliding rail 51 and a slider 52 that are slidably connected. The sliding rail 51 is fixedly connected to the slide block 4, and the slider 52 is fixedly connected to the base 3. The moving direction of the slide block 4 is parallel to the moving direction of the pressure head 7. Based on the assembly position of the sliding rail 51 and the slider 52, when the slide block 4 floats, the slider 52 remains stationary, and the sliding rail 51 and the slide block 4 move synchronously relative to the slider 52. This structure not only guides the up and down floating of the slide block 4, but also avoids friction and wear between the slide block 4 and the base 3, which would affect the service life of the equipment.

[0025] To ensure that the slide 4 floats smoothly relative to the base 3, two slide rails 51 are provided opposite each other, and each slide rail 51 is provided with at least two sliders 52. Compared with a single slide rail 51, providing two slide rails can ensure that the slide 4 moves more smoothly. Each slide rail 51 is provided with two sliders 52, and the two sliders 52 are distributed opposite each other on one side of the base 3, which can also ensure that the slide 4 moves more smoothly.

[0026] To prevent the slide block 4 from exceeding its travel range, a limiter 11 is provided on the base 3 to limit the vertical floating range of the slide block 4. The limiter 11 is located between the two slide rails 51, and there are two limiters 11, distributed at the upper and lower parts of the upper part of the base 3. When the slide block 4 moves to the limit position, the limiter 11 interferes with it, restricting it from continuing to move in that direction, which can prevent the slide block 4 from derailing and causing a safety accident. A proximity sensor is also provided on one side of the limiter 11, which is used to detect the position of the slide block 4 for data recording and control.

[0027] In addition, an adjusting bracket is provided on one side of the slide 4 to adjust the height between the press body 6 and the slide 4. That is, under the action of the adjusting bracket, the height of the slide 4 can be adjusted vertically, so that the press head 7 can be positioned above the product to be pressed, avoiding the problem of insufficient distance between the press head 7 and the product, and greatly improving the applicability of the device.

[0028] Working principle: The press body 6 is mounted on the slide 4 and connected to the base 3 via the sliding assembly 5. The press head 7 is mounted on the output end of the press body 6 and contacts the product on the tooling fixture 2 during pressing. During pressing, the press head 7 applies a downward pressure to the product and the tooling fixture 2, while the press body 6 experiences an upward reaction force. The slide 4, under the influence of the reaction force, moves upward. At this time, the slide 4 abuts against the underside of the protrusion 21 via the hook plate 41, that is, the slide 4 is hooked to the tooling fixture 2 and provides an upward support force to the tooling fixture 2, thereby counteracting the downward pressure on the tooling fixture 2. Based on this, the pressure on the tooling fixture 2 will not be transmitted to the turntable 1, which can effectively prevent the turntable 1 from deforming, improve pressing accuracy, and increase the life of the turntable 1.

[0029] Example 2

[0030] Based on Embodiment 1, the present invention also discloses an adjuster 8, which controls the height of the slide 4 relative to the base 3 to ensure that the clamp can rotate into place.

[0031] like Figures 1-3 As shown, an adjuster 8 for adjusting the height of the slide 4 is also provided on one side of the base 3. The adjuster 8 is located at the bottom of the slide 4, and one end of the adjuster 8 is connected to the slide 4, while the other end is connected to the base 3 through a support block 9. The support block 9 here is used to support the adjuster 8 so that it can be installed stably.

[0032] As described above, the adjuster 8 not only provides support for the slide 4, but also adjusts the position and height of the slide 4 relative to the base 3, so that when the press-fit structure is not in the press-fit state, there is a certain gap between the hook plate 41 and the protrusion 21, so that the turntable 1 can rotate into position under the action of the divider 10.

[0033] like Figure 6 As shown, the adjuster 8 includes a first adjusting screw 81 and a second adjusting screw 82 that are arranged opposite to each other. The first adjusting screw 81 is connected to the slide 4, the second adjusting screw 82 is connected to the support block 9, and a spring 83 is installed between the first adjusting screw 81 and the second adjusting screw 82.

[0034] Specifically, to facilitate the installation of spring 83, mounting seats are connected to the opposite ends of the first adjusting screw 81 and the second adjusting screw 82. By turning the first adjusting screw 81 or the second adjusting screw 82, the relative distance between the two mounting seats can be changed. Under the support of spring 83, the height of slide 4 relative to base 3 can be adjusted to ensure that turntable 1 can rotate smoothly into position. In addition, the elastic force of spring 83, supported by support block 9, can act on slide 4, and then be transmitted from slide 4 to tooling fixture 2, further ensuring that the pressure on tooling fixture 2 is not transmitted to turntable 1.

[0035] Example 3

[0036] Based on Embodiments 1 and 2, the present invention also proposes a pressing method, which adopts the above-mentioned online floating press pressing structure and includes the following steps: S1. The product to be pressed is clamped on the tooling fixture 2 of the turntable 1. The turntable 1 is driven by the divider 10 to rotate the tooling fixture 2 into position so that the product is located in the pressing area of ​​the press body 6. S2. Adjust the height of the slide block 4 relative to the base 3 by adjusting the adjuster 8 to ensure that there is a gap between the hook plate 41 and the protrusion 21 in the non-pressed state, so as to ensure that the tooling fixture 2 can rotate into place. S3. When the fixture 2 with the product in it rotates into place, the output end of the press body 6 presses down and contacts the product through the press head 7. At this time, the fixture 2 is subjected to downward pressure, and the press body 6 and the slide 4 are subjected to upward reaction force. S4, under the action of the reaction force, slide 4 moves upward relative to base 3 through sliding component 5 until hook plate 41 abuts against the bottom of protrusion 21, realizing the hook connection between slide 4 and tooling fixture 2; S5. When the bottom of the slide block 4 abuts against the lower end of the tooling fixture 2, the slide block 4 gives the tooling fixture 2 an upward lifting force to counteract the pressure of the pressure head 7 on the tooling fixture 2 and prevent the pressure from acting on the turntable 1 through the tooling fixture 2.

[0037] As described above, this method can ensure that the turntable 1 can rotate smoothly under the action of the divider 10, and can also effectively counteract the pressure generated by the press on the tooling fixture 2, so as to prevent the pressure from being transmitted downward to the turntable 1, causing the turntable 1 to deform and affecting the pressing accuracy and service life of the turntable 1.

[0038] In step S1, the pressing area of ​​the press body 6, that is, the area below the press head 7, uses a cam divider 10, which is a cam indexer or intermittent divider in the prior art. It is a high-precision rotary device that takes continuous rotation drive as input and outputs intermittent rotation, swinging or lifting actions. It is mainly used in automated processing, assembly, testing and other equipment. Here, it mainly outputs intermittent rotation actions.

[0039] Before loading the product onto the tooling fixture 2, the height between the press body 6 and the slide 4 can be adjusted by adjusting the bracket to ensure that there is sufficient working space between the press head 7 and the product.

[0040] The tooling fixtures 2 are provided on the turntable 1 in multiple ways and are arranged in a circular array around the axis of the turntable 1. The base 3, slide 4 and press body 6 are provided in at least one set. That is, multiple presses can simultaneously perform pressing operations on the products on the tooling fixtures 2, or operate on a part of the pressing process separately, or one press can perform pressing operations on multiple products.

[0041] In summary, the press-fitting structure proposed in this invention can float during operation. The turntable 1 and the tooling fixture 2 are rotated into position by the divider 10. The press presses down, so that the press head 7 contacts the tooling fixture 2. The tooling fixture 2 is subjected to downward pressure, and the press and the slide 4 are subjected to upward reaction force. The slide 4 moves upward through the sliding component 5, pressing against the lower end of the tooling fixture 2, giving the tooling fixture 2 an upward force to counteract the pressure of the press, so that the turntable 1 is not affected by the pressure of the press.
