[0005] In order to fix air conditioning filter elements of different specifications, the present application provides an air conditioning filter element adaptive tooling fixture.

[0006] This application provides an air conditioning filter element adaptive fixture, which adopts the following technical solutions:

[0008] By adopting the above technical solution, the setting of the block assembly is utilized to limit the first abutting surface and the second abutting surface of the air-conditioning filter element; the positioning frame is then utilized to form an abutting fit with the third abutting surface and the fourth abutting surface of the air-conditioning filter element, and the air-conditioning filter element is fixed to the base frame under the joint action of the positioning block and the positioning frame; the setting of the tightening assembly makes the abutment between the positioning frame and the side surface of the air-conditioning filter element more firmly fitted, and the positioning frame is slidably arranged along the side surface of the air-conditioning filter element toward the edge of the base frame, so that the size of the limiting space can be adjusted, and thus air-conditioning filters of different specifications can be fixed in the limiting space.

[0009] Preferably, a slide rail is provided on the base frame, and the positioning frame includes a slide plate and a slide block. The slide block is provided on the slide plate, and a side of the slide block facing away from the slide plate forms a sliding fit with the slide rail.

[0010] By adopting the above technical solution, the sliding block and the slide rail are used to form a sliding fit, so that the sliding block can drive the sliding plate to slide on the slide rail, making it convenient for staff to adjust the size of the limit space.

[0011] Preferably, a limiting groove is provided on the base frame, and the slide rail is detachably connected to the limiting groove.

[0012] By adopting the above technical solution and utilizing the setting of the limit groove, the slide rail is provided with a certain buffer space in the limit groove, thereby reducing the wear of the slide rail caused by vibration during use, and the slide rail can be detachably connected in the limit groove, thereby facilitating the staff to install, disassemble or replace the slide rail.

[0013] Preferably, a fixing bracket is provided on the base frame, a matching hole is opened on the fixing bracket, and the tightening assembly includes a sliding rod and a connecting block fixedly provided on the sliding plate, one end of the sliding rod is fixedly connected to the connecting block and forms an abutment fit with the air-conditioning filter element, the other end of the sliding rod is penetrated by a matching hole, an elastic member is sleeved on the outer wall of the sliding rod, one end of the elastic member forms an abutment fit with the connecting block, and the other end of the elastic member forms an abutment fit with a side of the fixing bracket close to the connecting block.

[0014] By adopting the above technical solution, one end of the sliding rod is fixedly connected to the connecting block and forms an abutment fit with the air-conditioning filter element, and a matching hole is provided at the other end, and an elastic part is abutted between the connecting block and the fixing frame. When the positioning frame slides toward the edge of the base frame, it is convenient for the staff to place the air-conditioning filter element into the limited space. When the air-conditioning filter element is placed, the elastic part on the sliding rod will drive the sliding rod and the positioning frame to retract and reset, so that the sliding rod will re-abut against the side of the air-conditioning filter element, thereby fixing the position of the air-conditioning filter element.

[0015] Preferably, a supporting block is fixedly connected to the sliding plate, and an avoidance hole is opened on the base frame along the thickness direction. The supporting block is arranged in the avoidance hole. A driving mechanism for driving the supporting block to slide along the side of the air-conditioning filter element toward the edge of the base frame is provided below the supporting block, and the driving mechanism is arranged on the base frame.

[0016] By adopting the above technical solution and utilizing the setting of the driving mechanism, the staff can drive the supporting block to slide by operating the driving mechanism, and the supporting block drives the sliding plate to slide along the edge of the base frame, thereby increasing the size of the limited space. At this time, the staff can place air-conditioning filters of different specifications into the limited space for fixing their position.

[0017] Preferably, a weight-reducing hole is provided through the bearing block.

[0018] By adopting the above technical solution and utilizing the arrangement of the weight-reducing holes, the weight of the bearing block is reduced, thereby facilitating the driving mechanism to drive the bearing block to slide along the side of the air conditioning filter element toward the edge of the base frame.

[0020] By adopting the above technical solution and utilizing the setting of the inclined surface and the cylinder, when the piston rod of the cylinder continuously presses the inclined surface upward, since the inclined surface is set toward the air-conditioning filter element, the supporting block will slide toward the edge of the base frame.

[0021] Preferably, a roller is rotatably connected to the piston rod of the cylinder, and the roller is in abutment with the inclined surface.

[0022] By adopting the above technical solution and utilizing the arrangement of the roller, the friction between the cylinder and the inclined surface of the receiving block is reduced, thereby improving work efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The stop block assembly is used to limit the first and second abutting surfaces of the air conditioning filter element; the positioning frame is then used to form an abutment fit with the third and fourth abutting surfaces of the air conditioning filter element, and the air conditioning filter element is fixed to the base frame under the joint action of the positioning block and the positioning frame; the tightening assembly is used to ensure that the abutment between the positioning frame and the side surface of the air conditioning filter element is more firmly fitted, and the positioning frame is slidably arranged along the side surface of the air conditioning filter element toward the edge of the base frame, so that the size of the limited space can be adjusted, thereby enabling air conditioning filters of different specifications to be fixed in the limited space;

[0033] The following is combined with Figure 3 -Attached Figure 5 This application is described in further detail.

[0034] An embodiment of the present application discloses an adaptive tooling fixture for an air conditioning filter element.

[0035] Reference Figure 3 and Figure 4 , an adaptive tooling fixture for an air-conditioning filter element, comprising a base frame 3 for placing an air-conditioning filter element 1, a block assembly 4 for limiting the positions of a first abutting surface 11 and a second abutting surface 12 of the air-conditioning filter element 1, and a positioning frame 5 for limiting the positions of a third abutting surface 13 and a fourth abutting surface 14 of the air-conditioning filter element 1, a limiting space for limiting the position of the air-conditioning filter element 1 is formed between the block assembly 4 and the positioning frame 5, and the position of the air-conditioning filter element 1 is fixed under the joint action of the block assembly 4 and the positioning frame 5.

[0036] Reference Figure 4 The base frame 3 includes an upper plate 31 and a lower plate 32. A connecting rod 33 is provided between the upper plate 31 and the lower plate 32. The connecting rod 33 is in the shape of a stepped rod and is provided with a trapezoidal surface 331. There are multiple connecting rods 33, and two are provided in this embodiment. Two limiting holes 311 are provided on the upper plate 31 along its thickness direction corresponding to the position and number of the connecting rods 33. One end of any connecting rod 33 is welded to the lower plate 32, and the end of any connecting rod 33 away from the lower plate 32 forms a plug-in fit with the corresponding limiting hole 311, and the trapezoidal surface 331 on any connecting rod 33 forms an abutment fit with the lower surface of the upper plate 31.

[0037] Reference Figure 3 and Figure 4The stopper assembly 4 includes a first stopper 41, a second stopper 42 and a third stopper 43. Two of the first stopper 41 and the second stopper 42 are provided. Any first stopper 41 is threadedly connected to the upper plate 31 by a bolt. Any first stopper 41 is provided with a snap-fitting groove 411 with an upward opening. The snap-fitting groove 411 of any first stopper 41 forms a detachable connection with the snap-fitting block 15 of the air conditioning filter element 1. In this embodiment, the snap-fitting groove 411 of any first stopper 41 forms a snap-fitting fit with the snap-fitting block 15 of the air conditioning filter element 1.

[0038] Reference Figure 3 and Figure 4 Any second stopper 42 is connected to the upper plate 31 by a bolt thread, and the second stopper 42 is located on the left and right sides of the first abutting surface 11 and forms an abutment fit with the first abutting surface 11. The third stopper 43 is connected to the upper plate 31 by a bolt thread and forms an abutment fit with the second abutting surface 12. The setting of the first stopper 41, the second stopper 42 and the third stopper 43 is used to limit the first abutting surface 11 and the second abutting surface 12 of the air conditioning filter element 1.

[0039] Reference Figure 4 and Figure 5 There are two positioning frames 5, which respectively form abutment with the third abutment surface 13 and the fourth abutment surface 14. A limiting groove 312 is provided on the upper plate 31 corresponding to the position of the positioning frame 5. One positioning frame 5 corresponds to two limiting grooves 312. The two limiting grooves 312 are symmetrically arranged at intervals. A slide rail 313 is detachably connected to any limiting groove 312 of the upper plate 31. In this embodiment, any slide rail 313 is threadedly connected to the corresponding limiting groove 312 by a bolt, so that the staff can easily install, disassemble or replace the slide rail 313.

[0040] Reference Figure 5 Since the structures and connection methods of the two positioning frames 5 are the same, one of them is used as an example for explanation.

[0041] Reference Figure 3 and Figure 5 The positioning frame 5 is slidably arranged along the corresponding side surface of the air conditioning filter element 1 toward the edge of the upper plate 31. The positioning frame 5 includes a sliding plate 51, a sliding block 52 and an abutting block 53. The abutting block 53 is located on the upper surface of the sliding plate 51 near the edge of the air conditioning filter element 1. The abutting block 53 forms an abutting fit with the third abutting surface 13 or the fourth abutting surface 14 of the air conditioning filter element 1.

[0042] Reference Figure 4 and Figure 5The sliding block 52 is located below the sliding plate 51 and is provided with two corresponding to the position and quantity of the sliding rail 313. Any sliding block 52 and the abutment block 53 are threadedly connected to the sliding plate 51 by bolts. Any sliding block 52 forms an embedded sliding fit with the corresponding sliding rail 313, so that the size of the limit space can be adjusted.

[0043] Reference Figure 4 and Figure 5 A bearing block 511 with a right-angled triangular cross-section is fixedly connected to the sliding plate 51. In this embodiment, the sliding plate 51 and the bearing block 511 are threadedly connected by bolts. An avoidance hole 314 is opened through the upper plate 31 along the thickness direction. The bearing block 511 is arranged in the avoidance hole 314. An L-shaped support plate 321 and a driving mechanism 322 for driving the bearing block 511 to slide in a direction away from the air-conditioning filter element 1 are provided on the lower plate 32. The support plate 321 is threadedly connected to the lower plate 32 by bolts. In this embodiment, the driving mechanism 322 includes a cylinder 3221, and the cylinder 3221 is threadedly connected to the support plate 321 by bolts.

[0044] Reference Figure 3 and Figure 5 The supporting block 511 is provided with an inclined surface 5111, which is arranged toward the air conditioning filter element 1. The piston rod of the cylinder 3221 is in contact with the inclined surface 5111, so that when the piston rod of the cylinder 3221 continuously presses the inclined surface 5111 upward, the supporting block 511 will slide toward the edge of the upper plate 31. Therefore, the staff only needs to operate the piston rod of the cylinder 3221 to extend and retract in the vertical direction to realize the sliding control of the supporting block 511 and the sliding plate 51, thereby improving the flexibility of the sliding control of the supporting block 511 and the sliding plate 51.

[0045] Reference Figure 5 The driving mechanism 322 includes a roller 3222, which is rotatably connected to the piston rod of the cylinder 3221. The roller 3222 forms an abutment fit with the inclined surface 5111, thereby reducing the friction between the cylinder 3221 and the inclined surface 5111 of the receiving block 511, thereby improving work efficiency.

[0046] Reference Figure 3 and Figure 5 A weight-reducing hole 5112 is provided through the supporting block 511, which reduces the weight of the supporting block 511, thereby facilitating the cylinder 3221 to drive the supporting block 511 to slide along the third abutting surface 13 or the fourth abutting surface 14 of the air conditioning filter element 1 toward the edge of the corresponding upper plate 31.

[0047] Reference Figure 3 and Figure 5The positioning frame 5 is provided with a tightening component 54 for strengthening the tightening force between the positioning frame 5 and the side of the air conditioning filter element 1. Two tightening components 54 are provided and are symmetrically arranged on the sliding plate 51. A fixing frame 315 is provided at the position corresponding to the tightening component 54 on the upper plate 31. The two fixing frames 315 are symmetrically arranged on both sides of the positioning frame 5, and any fixing frame 315 is threadedly connected to the upper plate 31 by a bolt. A matching hole 3151 is opened on any fixing frame 315. Since the structure and connection method of the two tightening components 54 are the same, one of the tightening components 54 is now taken as an example for explanation.

[0048] Reference Figure 3 and Figure 5 The tightening assembly 54 includes a sliding rod 541 and a connecting block 542 fixedly arranged on the sliding plate 51. One end of the sliding rod 541 is fixedly connected to the connecting block 542. In this embodiment, the connecting block 542 is threadedly connected to the sliding plate 51 by a bolt. The sliding rod 541 is threadedly connected to the connecting block 542 and forms an abutment fit with the air conditioning filter element 1. The other end of the sliding rod 541 is penetrated by a matching hole 3151 on the corresponding fixing frame 315, and the sliding rod 541 forms a sliding fit with the matching hole 3151. An elastic member 5411 is sleeved on the outer wall of the sliding rod 541. One end of the elastic member 5411 forms an abutment fit with the connecting block 542, and the other end of the elastic member 5411 forms an abutment fit with the side of the corresponding fixing frame 315 close to the connecting block 542. In this embodiment, the elastic member 5411 is set as a spring.

[0049] Reference Figure 3 and Figure 5 When the cam 511 is in contact with the side of the filter element 1, the spring 541 is pressed against the top of the filter element 1, and the spring 541 is pressed against the bottom of the filter element 1, thereby fixing the position of the filter element 1.

[0050] Reference Figure 3 and Figure 5 An open groove 316 is provided on the upper plate 31 near the third abutting surface 13, and the open groove 316 is connected to the avoidance hole 314. The setting of the open groove 316 makes it convenient for the staff to assemble and disassemble the bearing block 511; pull rings 317 are symmetrically provided on the upper plate 31 near the second abutting surface 12 and the fourth abutting surface 14, so as to facilitate the staff to lift and place the upper plate 31.

[0051] The implementation principle of the embodiment of the present application is as follows: during actual operation, the staff first forms an abutment fit between the first abutment surface 11 and the second abutment surface 12 of the air-conditioning filter element 1 through the first stop 41, the second stop 42 and the third stop 43 on the upper plate 31 to preliminarily limit the air-conditioning filter element 1. At the same time, the piston rod of the operating cylinder 3221 is used to realize the bearing block 511 and the sliding plate 51 to slide along the third abutment surface 13 or the fourth abutment surface 14 of the air-conditioning filter element 1 toward the edge of the corresponding upper plate 31, so that the size of the limiting space can be adjusted, thereby adapting to air-conditioning filter elements 1 of different specifications. After the air-conditioning filter element 1 is completely placed in the limiting space, the piston rod of any cylinder 3221 moves away from the corresponding bearing block 511, and under the action of the rebound force of the elastic member 5411, the abutment block 53 on any sliding plate 51 abuts against the air-conditioning filter element 1, thereby fixing the position of the air-conditioning filter element 1.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
