Description

Technical Field

[0001] This utility model relates to the field of rework tooling technology, specifically a novel core rework tooling. Background Technology

[0002] Currently, when assembling automotive heat exchanger cores on equipment, some defective products inevitably appear, especially for products like condenser cores and radiator cores, which are relatively thin but have large dimensions. Online rework is difficult to achieve and requires a long operation time, which directly affects the efficiency of normal production.

[0003] There are many offline repair methods, which generally involve using specialized equipment made with cylinders or hydraulics. This not only requires a large investment but also necessitates electrical and pneumatic connections. The equipment is fixed in one location, lacking flexibility and mobility, and making it difficult to quickly respond to frontline needs. Furthermore, it does not provide any assistance in clamping the core and relies solely on manual operation. Using commercially available adjustable clamps and binding wires is inefficient, with output per unit time being negligible compared to the quantity produced by normal equipment. Moreover, the repair process requires repeated clamping and loosening, as well as binding and clamping, which can easily damage the core and makes the processing method cumbersome. Therefore, this application proposes a new type of core repair tooling to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel core rework tooling, which has advantages such as rapid clamping assistance during offline rework of heat exchanger cores, and solves the problem of cumbersome processing methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel core rework fixture, including a workbench, a condenser core is provided on the top of the workbench, a positioning mechanism for positioning the condenser core is provided below the condenser core, and multiple clamping plates are provided above the workbench;

[0006] The condenser core is provided with a clamp on its outer side, and four support columns are provided above the workbench.

[0007] Furthermore, the condenser core is movably attached to the top of four support columns, and there are six clamping plates divided into two groups, with two columns welded to the bottom of each group of clamping plates.

[0008] Furthermore, the positioning mechanism includes multiple mounting seats disposed on the upper surface of the workbench, and the multiple mounting seats are divided into three groups and distributed to the rear side. The interior of the middle mounting seat is rotatably connected to a T-shaped lead screw via a bearing. A nut is engaged on the outer side of the T-shaped lead screw, and a base is sleeved on the outer side of the nut. A connecting plate is fixed to the upper surface of the base by bolts. Linear ball bearing seats are disposed on the lower surface of the connecting plate and on both the left and right sides of the base. An optical shaft is sleeved inside each of the two linear ball bearing seats.

[0009] Furthermore, the positioning mechanism also includes a rocker arm disposed at the front end of the T-shaped lead screw, and the multiple clamping plates have the same vertical height.

[0010] Furthermore, the rear columns are all welded to the upper surface of the workbench, and the front columns are all welded to the upper surface of the connecting plate.

[0011] Furthermore, the two optical axes are rotatably connected inside the mounting bases on the left and right sides, and rubber pads are provided on the lower surfaces of the multiple clamping plates.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This new core repair fixture uses a rotating rocker arm to move multiple clamping plates in a straight line to the rear, clamping the condenser core. The fixture allows for repair and parts replacement of the condenser core (defective product), achieving the advantages of convenient and flexible repair work without the need for gas or electricity.

[0019] 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.

[0020] Please see Figures 1 to 2 The novel core rework fixture in this embodiment includes a workbench 1, a condenser core 6 on the top of the workbench 1, a positioning mechanism 2 for positioning the condenser core 6 below the condenser core 6, and multiple clamping plates 4 above the workbench 1.

[0021] The condenser core 6 is provided with a clamp 5 on the outside, and four support columns 7 are provided above the workbench 1. The condenser core 6 is movably attached to the top of the four support columns 7. There are six clamping plates 4 in total, which are divided into two groups. Two columns are welded to the bottom of each group of clamping plates 4.

[0022] Understandably, the workbench 1 serves to support and limit the condenser core 6, preventing positional changes in the device during clamping and releasing operations. In use, the operator places the condenser core 6 with clamps 5 upside down on the four support columns 7, and initially positions it on the lower surface of the three rear clamping plates 4. The operator rotates the rocker arm, at which point the multiple front clamping plates 4 move linearly to the rear, and the multiple rear clamping plates 4 are fixedly set on the fixture, which can achieve the purpose of clamping the condenser core 6. Furthermore, the T-shaped lead screw 203 transmits force smoothly and can transmit a large force. After the condenser core 6 is clamped stably, the clamps 5 on its outer side can be removed. The operator then rotates the rocker arm in the opposite direction to make the front clamping plates 4 retract, thereby releasing the core. The condenser core 6 (defective product) can then be repaired and parts replaced on the rework fixture.

[0023] Please see Figures 3 to 4 In this embodiment, the positioning mechanism 2 includes multiple mounting seats 206 disposed on the upper surface of the workbench 1. The multiple mounting seats 206 are divided into three groups and extend to the rear side. The interior of the middle mounting seat 206 is rotatably connected to a T-shaped lead screw 203 through a bearing. A nut 202 is engaged on the outer side of the T-shaped lead screw 203. A base 201 is sleeved on the outer side of the nut 202. A connecting plate 3 is fixed to the upper surface of the base 201 by bolts. Linear ball bearing seats 204 are disposed on the lower surface of the connecting plate 3 and on both the left and right sides of the base 201. A light shaft 205 is sleeved inside each of the two linear ball bearing seats 204. The connecting plate 3 is fastened together with the linear ball bearing seats 204 on both sides of the light shaft 205 by bolts, thereby forming a double-track threaded transmission structure, realizing the conversion of rotary motion into linear reciprocating motion.

[0024] The positioning mechanism 2 also includes a rocker arm set at the front end of the T-shaped lead screw 203. Multiple clamping plates 4 on the front side are fixed on the motion connecting plate 3 and move forward or backward with the connecting plate 3. Relying on the characteristics of the T-shaped lead screw 203 to transmit force smoothly and transmit a large torque, and with the addition of the rocker arm to increase the lever arm length, the purpose of clamping the condenser core 6 can be easily and quickly achieved. The multiple clamping plates 4 have the same vertical height. The rear columns are all welded to the upper surface of the workbench 1, and the front columns are all welded to the upper surface of the connecting plate 3. The two optical shafts 205 are respectively rotatably connected to the inside of the mounting seats 206 on the left and right sides. Rubber pads are provided on the lower surface of the multiple clamping plates 4. After the repair is completed, the rocker arm is rotated again to clamp the condenser core 6, and the condenser core 6 is fixed by the clamp 5. The rocker arm is rotated in the opposite direction to release the condenser core 6. Then the condenser core 6 and the clamp 5 can be taken out together to complete the rework of the condenser core 6 (defective product).

[0025] Understandably, by rotating the rocker arm, the multiple clamping plates 4 on the front side move linearly to the rear side, achieving the purpose of clamping the condenser core 6. On the rework fixture, the condenser core 6 (defective product) can be repaired and parts replaced, achieving the advantages of convenient and flexible rework without the need for gas or electricity connection.

[0026] All electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so this utility model will not explain the control method and circuit connection in detail. At the same time, any parts of this utility model that are not described in detail are all common technologies known to those skilled in the art.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The working principle of the above embodiments is as follows:

[0029] The workbench 1 serves to support and limit the condenser core 6, preventing positional changes during clamping and releasing operations. In use, the operator places the condenser core 6, equipped with clamps 5, upside down on the four support columns 7, initially positioning it on the lower surface of the three rear clamping plates 4. The operator then rotates the rocker arm, causing the front clamping plates 4 to move linearly rearward. Since the rear clamping plates 4 are fixedly mounted on the fixture, they effectively clamp the condenser core 6. The T-screw 203 provides stable force transmission and can deliver significant power. Once the condenser core 6 is stably clamped, the outer clamps 5 can be removed. The operator then reverses the rocker arm to retract the front clamping plates 4, releasing the core. The condenser core 6 (defective product) can then be repaired and parts removed using the rework fixture. After replacement and other repair operations are completed, the rocker arm is rotated again to clamp the condenser core 6, and the condenser core 6 is fixed by the clamp 5. The rocker arm is rotated in the opposite direction to release the condenser core 6. Then the condenser core 6 and the clamp 5 can be taken out together to complete the rework of the condenser core 6 (defective product). The connecting plate 3 is fastened to the linear ball bearing seats 204 on both sides of the optical shaft 205 by bolts, thus forming a double-rail threaded transmission structure, realizing the conversion of rotary motion into linear reciprocating motion. Multiple clamping plates 4 on the front side are fixed on the moving connecting plate 3 and move forward or backward with the connecting plate 3. Relying on the characteristics of the T-shaped screw 203 to transmit force smoothly and transmit a large torque, plus the rocker arm to increase the lever arm length, the purpose of clamping the condenser core 6 can be achieved easily and quickly.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
