Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a tooling fixture. Background Art

[0002] During the machining process, the workpiece needs to be clamped with a fixture to prevent displacement and vibration. Currently, the applicability of fixtures is poor. Specific fixtures need to be developed separately for different processing equipment or different workpieces, which increases costs. Taking the cover of the evaporator water chamber as an example, the water chamber cover needs to be punched, and the cover is curved. In order to punch holes on the edge of the cover, the cover needs to be tilted. However, different sizes of covers and punching equipment have different requirements for tilt angles, so separate fixtures need to be developed, which increases the processing cost of the workpiece.

DETAILED DESCRIPTION

[0029] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0031] Currently, the applicability of fixtures is poor. Specific fixtures need to be developed separately for different processing equipment or different workpieces, which increases the overall cost of the workpiece manufacturing process. This application provides a fixture to solve the related technical problems.

[0032] Figures 1 to 4 It is a structural diagram of the tooling fixture in the first embodiment of the present application. Figures 5 to 9 This is a structural diagram of the fixture in the second embodiment of the present application. In the first embodiment, as Figure 1 As shown, the fixture may include a base 10 , a workpiece mounting seat 20 , a holding assembly 30 , a first reducer 40 , a locking assembly 50 and a pressing assembly 60 .

[0033] A workpiece mounting base 20 is mounted to one side of the base 10. The base 10 includes a main flat surface 100 facing the workpiece mounting base 20. The workpiece mounting base 20 is provided with a workpiece mounting surface 200 on a side facing away from the base 10. The base 10 and the workpiece mounting base 20 are rotatably connected so that the main flat surface 100 and the workpiece mounting surface 200 can form a predetermined angle. A retaining assembly 30 is fixed to the main flat surface 100. When the workpiece is clamped in the fixture, the retaining assembly 30 securely connects the base 10 and the workpiece mounting base 20.

[0034] By rotating the base 10 and the workpiece mounting seat 20, the angle between the workpiece mounting surface 200 and the main plane 100 can be changed. Figure 1 The fixture can adjust the angle between the workpiece mounting surface 200 and the main plane 100 to adapt to the processing requirements of different workpieces or different processing equipment, thereby improving applicability.

[0035] Specifically, taking drilling a hole in the cover 80 of the evaporator water chamber as an example, after the cover 80 is secured to the workpiece mounting surface 200, the workpiece mounting base 20 is rotated to adjust the inclination of the cover 80. This allows the main plane 100 and the workpiece mounting surface 200 to form a predetermined angle, positioning the portion of the cover 80 to be processed upward and aligned with the drill bit of the drilling equipment, thereby enabling the drilling process. The angle formed by the main plane 100 and the workpiece mounting surface 200 can be up to 60°, but the specific value is not limited.

[0036] like Figure 2 As shown, the base 10 is plate-shaped. The base 10 protrudes from the main plane 100 to form a pair of lugs 101. The workpiece mounting base 20 may include a chassis 21, a turntable 22 and a bearing 23. The chassis 21 is rotatably connected to the base 10.

[0037] Specifically, the chassis 21 can extend toward the base main plane 100 to form a pair of support plates 211. The support plates 211 are assembled and rotated in correspondence with the lugs 101 to achieve a rotational connection between the base 10 and the workpiece mounting base 20. The specific connection method between the base 10 and the workpiece mounting base 20 is not limited, as long as the two can rotate relative to each other.

[0038] The turntable 22 is rotatably connected to the chassis 21. The workpiece mounting surface 200 is provided on the turntable 22. The rotation axis of the chassis 21 and the turntable 22 is perpendicular to the workpiece mounting surface 200. That is: Figure 2 The Z axis is perpendicular to the workpiece mounting surface 200. By rotatably connecting the turntable 22 to the chassis 21, the fixture can change the relative position of the workpiece by rotating the turntable 22, eliminating the need to develop new fixtures for different processing positions, further improving the applicability of the fixture.

[0039] The turntable 22 and the chassis 21 can be rotatably connected via the bearing 23. Figure 3 As shown, bearing 23 includes an inner ring 231 and an outer ring 232. Inner ring 231 is fixed to chassis 21. Outer ring 232 is fixed to turntable 22. When turntable 22 rotates relative to chassis 21, inner ring 231 rotates relative to outer ring 232. Bearing 23 provides support and improves stability during rotation. Bearing 23 can be a crossed roller bearing, capable of withstanding significant radial and axial forces. The specific type of bearing is not limited.

[0040] like Figure 1 and Figure 3 As shown, the holding assembly 30 may include a lifting mechanism 301, such as a jack. The ends of the lifting mechanism 301 abut the main plane 100 and the workpiece mounting base 20, respectively, so that the lifting mechanism 301 can push the workpiece mounting base 20 to rotate relative to the base 10. The holding assembly 30 can simultaneously provide support and rotation, simplifying the structure and reducing costs.

[0041] like Figure 3 As shown, the first speed reducer 40 may include a first body 41 and a first output shaft 42. The first output shaft 42 protrudes from the first body 41. The first body 41 is fixed to the chassis 21, and the first output shaft 42 is connected to the turntable 22. The provision of a speed reduction mechanism can increase the torque applied to the turntable 22, enhancing the stability of the turntable 22 during rotation. Furthermore, the first speed reducer 40 may have a certain degree of self-locking function to prevent the turntable 22 from being difficult to stop after rotation.

[0042] Specifically, the reduction ratio of the first reducer 40 can be 1:50. The first reducer 40 can provide input torque through the first hand wheel 43, or through a motor or other components. The specific torque input method of the first reducer 40 is not limited.

[0043] like Figure 3 As shown, the turntable 22 is provided with a locking hole 221. The locking assembly 50 is threadedly connected to the locking hole 221. When the workpiece is clamped, the locking assembly 50 abuts the chassis 21, securing the chassis 21 to the turntable 22. Because the locking assembly 50 is threadedly connected to the locking hole 221, the locking assembly 50 can be abutted against the chassis 21 by rotating the locking assembly 50, resulting in high locking efficiency.

[0044] Specifically, if Figure 4 As shown, the locking assembly 50 may include a locking member 51 and a toggle member 52. The locking member 51 is threadedly connected to the locking hole 221. One end of the locking member 51 is used to abut the chassis 21, and the other end is used to mount the toggle member 52. The end of the toggle member 52 is assembled to the locking member 51 to increase the moment arm of the toggle member 52, thereby increasing the torque transmitted from the toggle member 52 to the locking member 51 and accelerating the locking speed of the locking assembly 50.

[0045] like Figure 3 and Figure 4 As shown, the workpiece mounting surface 200 is provided with a guide groove 201. The clamping assembly 60 is slidably connected to the guide groove 201. The clamping assembly 60 is used to secure the workpiece. Due to the sliding connection between the clamping assembly 60 and the guide groove 201, the clamping assembly 60 has a certain range of motion, which allows it to clamp workpieces of different sizes, further improving the applicability of the fixture.

[0046] The guide groove 201 can pass through the side of the workpiece mounting base 20, and the pressing assembly 60 can be directly assembled to the guide groove 201 through the side of the workpiece mounting base 20, thereby improving the installation efficiency. Specifically, the guide groove 201 can be T-shaped, and the specific shape is not limited.

[0047] like Figures 2 to 4As shown, the clamping assembly 60 may include a connecting shaft 61, a pressure plate 62, a nut 63, a pressure block 64, and a support block 65. The connecting shaft 61 is slidably mounted in the guide groove 201. The connecting shaft 61 includes a first end 611 extending beyond the workpiece mounting surface 200. The pressure plate 62 is provided with a mounting hole 621 that is rotatably connected to the first end 611.

[0048] Because the first end 611 is rotatably connected to the mounting hole 621, the pressure plate 62 can rotate relative to the connecting shaft 61 to accommodate the securing requirements of workpieces of varying shapes and sizes, thereby enhancing the applicability of the fixture. The mounting hole 621 can be elongated, allowing the pressure plate 62 to slide along the length of the mounting hole 621, increasing its range of motion and further improving the applicability of the fixture.

[0049] Nuts 63 and pressure blocks 64 are assembled to both ends of the connecting shaft 61. When the fixture is clamped, nuts 63 are tightened, clamping the workpiece and workpiece mounting base 20 between the pressure plate 62 and pressure blocks 64. The ends of the support block 65 abut against the pressure plate 62 and the workpiece mounting base 20, respectively. In other embodiments, the specific structure of the clamping assembly 60 is not limited.

[0050] The number of clamping assemblies 60 can be multiple and spaced apart along the circumference, allowing the fixture to secure a disc-shaped workpiece. Because the clamping assemblies 60 are slidably connected to the guide groove 201, the fixture can secure an elliptical workpiece. The specific number and distribution of the clamping assemblies 60 are not limited.

[0051] like Figure 1 and Figure 2 As shown, in the first embodiment, when installing a workpiece, taking the installation of the cover 80 as an example, first, the workpiece mounting base 20 is placed in a horizontal position. Then, the cover 80 is placed on the workpiece mounting surface 200 and secured to the turntable 22 via the clamping assembly 60. Next, the turntable 22 is rotated by the first reducer 40 until the cover 80 reaches a predetermined position, and the turntable 22 is secured to the chassis 21 via the locking assembly 50. Finally, the lifting mechanism 301 is adjusted to push the workpiece mounting base 20 to a predetermined angle.

[0052] In the second embodiment of the present application, Figure 5 As shown, the fixture may include a base 10, a workpiece mounting base 20, a holding assembly 30, a first reducer 40, a locking assembly 50, a pressing assembly 60, and a second reducer 70. In the second embodiment, the structures of the first reducer 40, the locking assembly 50, and the pressing assembly 60 are the same as those of the first embodiment and are not further described.

[0053] like Figure 6As shown, the base 10 may include a first rod 11, a second rod 12, and a reinforcement rod 13. The first rod 11 and the second rod 12 are arranged opposite each other. The reinforcement rod 13 connects the first rod 11 and the second rod 12. The base 10 is formed by fixing multiple rods, which provides high structural strength and improves the stability of the fixture. The number of reinforcement rods 13 can be two to further enhance structural strength, but the specific number is not limited. The first rod 11, the second rod 12, and the reinforcement rod 13 can be square steel structures.

[0054] The first rod 11 is provided with a side plate 111. A mounting platform 112 is provided on the side plate 111. The mounting platform 112 can be used to mount a rotating bearing to ensure stability during the rotation of the workpiece mounting base 20. Reinforcing ribs 113 are connected between the side plate 111 and the first rod 11 to enhance the structural strength of the base 10.

[0055] like Figure 7 and Figure 8 As shown, in the second embodiment, similar to the first embodiment, the workpiece mounting base 20 may also include a chassis 21, a turntable 22, and a bearing 23. The turntable 22 is rotatably connected to the chassis 21, and the rotation axes of the two are perpendicular to the workpiece mounting surface 200, so as to adjust the position of the workpiece.

[0056] The retaining assembly 30 may include a pair of opposing clamping plates 31. A fixing plate 212 is provided on the side of the workpiece mounting base 20 facing the main plane 100. The fixing plate 212 extends from the chassis 21 toward the base 10 and between the pair of clamping plates 31. When the workpiece is clamped, the pair of clamping plates 31 clamp the fixing plate 212. In this state, the workpiece mounting base 20 is less likely to move, thereby improving the stability of the fixture.

[0057] The retaining assembly 30 can be controlled by pneumatic pressure and comprises a base 32 and a pair of clamping plates 31. The base 32 is fixed to the reinforcing rod 13. The clamping plates 31 extend from the base 32. When the workpiece mounting base 20 is rotated to a predetermined angle, the clamping plates 31 clamp the fixing plate 212 using pneumatic pressure. This pneumatic control eliminates electrical sparks and provides high safety and explosion resistance. The retaining assembly 30 can also be controlled hydraulically, and the specific control method is not limited.

[0058] like Figure 6 and 7 As shown, the second reducer 70 may include a second body 71 and a second output shaft 72. The second output shaft 72 protrudes from the second body 71. The second body 71 is fixed to the base 10, and the second output shaft 72 is connected to the workpiece mounting base 20. Specifically, a support plate 14 may be provided on the mounting table 112, and the second body 71 is assembled to the support plate 14. A connecting block 213 may be provided on the turntable 22, and the second output shaft 72 is mounted to the connecting block 213.

[0059] The second reducer 70 is provided to increase the torque applied to the workpiece mounting base 20 and enhance the stability of the workpiece mounting base 20 during rotation. In the second embodiment, the maximum preset angle between the main plane 100 and the workpiece mounting surface 200 is not limited and can be 60 degrees.

[0060] The second reducer 70 can provide input torque via a second hand wheel 73 or a motor or other component. The specific method of providing input torque is not limited. When both the first reducer 40 and the second reducer 70 provide input torque via a motor, the two rotational directions of the turntable 22 can be automatically controlled without manual operation.

[0061] like Figure 8 and Figure 9 As shown in the second embodiment, when installing a workpiece, using the installation of the cover 80 as an example, first, the workpiece mounting base 20 is placed in a horizontal position. Then, the cover 80 is mounted on the workpiece mounting surface 200 and secured to the turntable 22 via the clamping assembly 60. Next, the turntable 22 is rotated by the first reducer 40 until the cover 80 reaches a predetermined position, and the turntable 22 is secured to the chassis 21 via the locking assembly 50. Finally, the turntable 22 is rotated by the second reducer 70 until the cover 80 reaches a predetermined angle.

[0062] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
