Description

Technical Field

[0001] This utility model relates to the field of hot pressing equipment technology, specifically to an adaptive mechanism for eliminating tooling height errors. Background Technology

[0002] A hot press is a device that heats two pre-fluxed and tinned parts to a temperature sufficient to melt and flow the solder. After solidification, a permanent electromechanical connection is formed between the parts and the solder. Hot presses have functions such as fast response speed, precise energy control, and fault diagnosis.

[0003] A hot press with a multi-point positioning structure, disclosed in CN218399115U, includes a worktable and a cooling assembly. A lower mold is centrally located inside the worktable, and thermally conductive silicone grease is applied to its bottom surface. A cooling tank is connected to the bottom surface of the thermally conductive silicone grease, and a partition is installed inside the cooling tank. Connecting pipes are connected to both sides of the cooling tank, and a pump body is installed in the middle of the right connecting pipe. A water tank is connected to the bottom end of the connecting pipe. The cooling assembly for rapid cooling is located inside the water tank. Through the cooling assembly, the hot press can transfer the temperature of the cooling water in the water tank to the heat dissipation plate via a heat-conducting plate. Simultaneously, the fins increase the heat dissipation area of ​​the heat-conducting plate, and the fan accelerates the airflow within the support frame, thereby rapidly cooling the heat-conducting plate and preventing the cooling water temperature in the water tank from becoming excessively high, thus improving the cooling effect.

[0004] However, the patent still has the following problems in actual use: When the tooling is used for hot pressing welding, the flatness of the tooling needs to be adjusted to avoid unevenness after the tooling is positioned, which would affect the subsequent hot pressing effect of the tooling. It is also necessary to keep the clamping pressure of the tooling stable to facilitate subsequent precise hot pressing.

[0005] Therefore, an adaptive mechanism to eliminate tooling height error is proposed to solve the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide an adaptive mechanism to eliminate tooling height errors, so as to solve the problem that unevenness after tooling positioning affects the subsequent hot pressing effect of the tooling, and makes it difficult to maintain the stability of the clamping pressure of the tooling, thus hindering the accuracy of subsequent hot pressing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adaptive mechanism for eliminating tooling height errors, comprising a base plate, a tooling product, and a fixture plate slidably mounted above the base plate;

[0008] Also includes:

[0009] An adjustment assembly is provided on the top of the base plate, and a positioning assembly is provided on the top of the fixture plate. The adjustment assembly includes two slide rails fixedly installed on the top of the base plate. A sliding strip is slidably connected to one side of each slide rail, and the top ends of both sliding strips are fixedly connected to the bottom of the fixture plate.

[0010] Among them, a tension spring is fixedly installed in the middle of one side of the sliding bar, the bottom end of the tension spring is fixedly connected to the top of the base plate, a support cylinder is fixedly installed on one side of the top of the base plate, and a floating head is fixedly installed on the other side of the top of the base plate.

[0011] The positioning component includes a rear clamping block that is longitudinally slidably mounted on the top of the fixture plate, and a front limiting member that is fixedly mounted on the top of the fixture plate.

[0012] Preferably, the sliding bar is inverted L-shaped, the tension spring is fixedly installed by bolts, and the support cylinder is located between the two sliding bars.

[0013] Preferably, a mounting plate is fixedly connected to the top of the base plate on the other side, and the floating head is vertically installed on the inner side of the mounting plate, with the floating head located below the fixture plate.

[0014] Preferably, a first cylinder is fixedly installed on one side of the bottom of the fixture plate, a movable seat is fixedly connected to the output end of the first cylinder, a sliding groove is provided on one side of the interior of the fixture plate, and a vertical plate is fixedly connected to the top of the movable seat.

[0015] Preferably, the movable seat is located on one side of the front of the first cylinder, the vertical plate is slidably connected to the sliding groove, and the vertical plate is in contact with the inner wall of the sliding groove.

[0016] Preferably, a rear clamping block is fixedly connected to the top of the vertical plate through the sliding groove, the rear clamping block is in contact with the top surface of the jig plate, and a front limiting member is fixedly connected to one side of the top front of the jig plate.

[0017] Preferably, a second cylinder and a left limiting member are fixedly installed on the top two sides of the jig plate, the rear clamping block is in contact with the inner side wall of the left limiting member, and a processing groove is provided on the other side of the jig plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an adjustment component, after the tooling product is clamped and positioned, the elastic force of the tension spring drives the sliding bar and the fixture plate to descend. The tension spring is used to ensure the stability of the sliding tension of the fixture plate and to eliminate vibration after positioning. The floating head is used to reduce the height error requirements of the tooling product and the fixture plate when the material is received. It also provides a certain floating effect according to the welding state, which helps to maintain the pressure stability and flatness requirements of the tooling product, improve the product qualification rate, and improve the subsequent hot pressing accuracy. The specific details are as follows:

[0019] 1. By setting up the adjustment component, the operator first pulls the fixture plate, which drives the sliding bar to rise. The slide rail limits the sliding of the sliding bar, ensuring that the fixture plate and the sliding bar can move stably up and down. The sliding bar also acts on the tension spring, causing the tension spring to be stretched. Then, the tooling product is clamped and positioned by the positioning component. The operator releases the fixture plate, and the elasticity of the tension spring drives the sliding bar and the fixture plate to fall. The tension spring is used to ensure the stability of the sliding tension of the fixture plate. The floating head is used to reduce the height error of the tooling product when it is received. It makes a certain floating action according to the welding state, and the support cylinder limits the descent of the fixture plate, reducing the impact damage to the equipment electrodes when the fixture plate falls too low. This makes it easier to maintain the pressure stability and flatness requirements of the tooling product, improve the subsequent hot pressing accuracy, and solve the problem that unevenness after tooling positioning affects the subsequent hot pressing effect of the tooling, and makes it difficult to maintain the stability of the clamping pressure of the tooling, which hinders the subsequent hot pressing accuracy.

[0020] 2. By setting up positioning components, the operator places the tooling product to be processed on the top of the fixture plate, starts the first and second cylinders, the first cylinder drives the moving seat to move, the moving seat drives the vertical plate to move, the vertical plate slides inside the sliding groove, the vertical plate drives the rear clamping block to move, the rear clamping block pushes the tooling product to move, and cooperates with the front limiting component to clamp the front and rear sides of the tooling product. The second cylinder cooperates with the left limiting component to clamp the left and right sides of the tooling product, thereby maintaining the positioning and clamping of the tooling product, reducing the positioning deviation of the tooling product, and facilitating subsequent accurate hot pressing processing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 - Figure 7 The present invention provides a technical solution: an adaptive mechanism for eliminating tooling height error, comprising a base plate 1, a tooling product 5, and a fixture plate 2 slidably mounted on the base plate 1.

[0031] An adjustment assembly 3 is provided on the top of the base plate 1. The adjustment assembly 3 includes two slide rails 31 fixedly installed on the top of the base plate 1. A sliding strip 32 is slidably connected to one side of the slide rail 31. The top ends of the two sliding strips 32 are fixedly connected to the bottom of the fixture plate 2.

[0032] A tension spring 33 is fixedly installed in the middle of one side of the sliding bar 32. The tension spring 33 is made of stainless steel. The bottom end of the tension spring 33 is fixedly connected to the top of the base plate 1. A support cylinder 34 is also fixedly installed on one side of the top of the base plate 1. A floating head 36 is fixedly installed on the other side of the top of the base plate 1.

[0033] The sliding bar 32 is designed in an inverted L shape, the tension spring 33 is fixedly installed by bolts, and the support cylinder 34 is located between the two sliding bars 32.

[0034] A mounting plate 35 is fixedly connected to the top of the base plate 1 on the other side. The floating head 36 is vertically installed on the inside side of the mounting plate 35. The floating head 36 is located below the fixture plate 2. The floating head 36 is model FJRHA5-0.8.

[0035] The operator first pulls the fixture plate 2, which causes the sliding bar 32 to rise. The slide rail 31 limits the sliding of the sliding bar 32, ensuring that the fixture plate 2 and the sliding bar 32 can move stably up and down. The sliding bar 32 acts on the tension spring 33, causing the tension spring 33 to be stretched. Then, the tooling product 5 is clamped and positioned by the positioning component 4. The operator releases the fixture plate 2, and the elastic force of the tension spring 33 causes the sliding bar 32 and the fixture plate 2 to fall. The tension spring 33 is used to ensure the stability of the sliding tension of the fixture plate 2.

[0036] The floating head 36 is used to reduce the height error of the tooling product 5 when the material is received. It floats according to the welding state and supports the cylinder 34 to limit the descent of the fixture plate 2, reducing the impact damage to the equipment electrodes when the fixture plate 2 is lowered too low. This makes it easier to maintain the pressure stability and flatness requirements of the tooling product 5 and improve the subsequent hot pressing accuracy.

[0037] The top of the fixture plate 2 is provided with a positioning component 4, which includes a rear clamping block 45 that is longitudinally slidably installed on the top of the fixture plate 2, and a front limiting member 46 that is fixedly installed on the top of the fixture plate 2.

[0038] A first cylinder 41 is fixedly installed on one side of the bottom of the fixture plate 2. A movable seat 42 is fixedly connected to the output end of the first cylinder 41. A sliding groove 43 is opened on one side of the interior of the fixture plate 2. A vertical plate 44 is fixedly connected to the top of the movable seat 42.

[0039] The movable seat 42 is located on one side of the front of the first cylinder 41, and the vertical plate 44 is slidably connected to the sliding groove 43, with the vertical plate 44 fitting against the inner wall of the sliding groove 43.

[0040] The top of the vertical plate 44 is fixedly connected to the rear clamping block 45 through the sliding groove 43. The rear clamping block 45 is in contact with the top surface of the jig plate 2. The front limiting member 46 is fixedly connected to one side of the top front of the jig plate 2.

[0041] The operator places the tooling product 5 to be processed on the top of the fixture plate 2, and starts the first cylinder 41 and the second cylinder 47. The first cylinder 41 drives the moving seat 42 to move, the moving seat 42 drives the vertical plate 44 to move, the vertical plate 44 slides inside the sliding groove 43, the vertical plate 44 drives the rear clamping block 45 to move, the rear clamping block 45 pushes the tooling product 5 to move, and cooperates with the front limiting part 46 to clamp the front and rear sides of the tooling product 5.

[0042] The second cylinder 47, in conjunction with the left-side limiting component 48, clamps the left and right sides of the tooling product 5, thereby maintaining the positioning and clamping of the tooling product 5, reducing the positioning deviation of the tooling product 5, and facilitating subsequent accurate hot pressing processing.

[0043] The top two sides of the jig plate 2 are respectively fixedly installed with the second cylinder 47 and the left limiting member 48. The rear clamping block 45 is in contact with the inner side wall of the left limiting member 48. The other side of the jig plate 2 is provided with a machining groove 49. The first cylinder 41 and the second cylinder 47 are selected as SC standard cylinders.

[0044] Working principle:

[0045] Before using this adaptive mechanism to eliminate tooling height errors, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7 As shown, the operator first pulls the fixture plate 2, which causes the sliding bar 32 to rise. Simultaneously, the sliding bar 32 acts on the tension spring 33, causing it to stretch. Then, the tooling product 5 to be processed is placed on top of the fixture plate 2. The first cylinder 41 and the second cylinder 47 are then activated. The first cylinder 41 moves the moving seat 42, which in turn moves the vertical plate 44. The vertical plate 44 slides inside the sliding groove 43, causing the rear clamping block 45 to move. The rear clamping block 45 pushes the tooling product 5 forward and, in conjunction with the front limiting member 46, holds the tooling product 5 in place. The second cylinder 47, in conjunction with the left limiting component 48, clamps the tooling product 5 on both sides, thereby maintaining the positioning and clamping of the tooling product 5. Finally, the operator releases the fixture plate 2, and the elastic force of the tension spring 33 drives the sliding bar 32 and the fixture plate 2 to descend. The tension spring 33 is used to ensure the stability of the sliding tension of the fixture plate 2. The floating head 36 is used to reduce the height error requirement of the tooling product 5 when the material is received. It makes a certain floating action according to the welding state, and the support cylinder 34 limits the descent of the fixture plate 2, reducing the impact damage to the equipment electrodes when the fixture plate 2 descends too low.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
