Description

Technical Field

[0001] This utility model relates to the field of fan processing technology, and more specifically to a positioning device for processing the mounting base of a jet fan. Background Technology

[0002] Existing jet fans need to be installed on the roof of places such as tunnels. They need to be mounted on the roof. The mounting base is generally made of a horizontal beam made of channel steel, with multiple bent connecting blocks welded to the bottom. The corresponding connecting base of the jet fan is fixed to the bent connecting blocks by bolts to achieve the connection. The horizontal beam is fixed to the roof of the tunnel or other places.

[0003] Therefore, during the processing of the mounting base, the bent connecting blocks to be welded need to be manually welded and fixed to the transverse beam. This requires first measuring and positioning the position to be welded on the transverse beam, marking the position, and then welding the bent connecting blocks at the marked positions, which is a complicated process. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a positioning device for processing the mounting base of a jet fan. It does not require marking the corresponding position of the transverse beam. After positioning the transverse beam, the bent connecting block to be welded is inserted into the corresponding through hole. The position where its bottom presses against the top surface of the transverse beam is the installation position. It can be directly spot welded or welded to fix it. It is convenient to process and has high processing efficiency.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A positioning device for machining the mounting base of a jet fan includes a machining platform, wherein an upper support frame is fixed to the top surface of the top plate of the machining platform.

[0007] A lifting mechanism is installed on the top plate of the upper support frame. A bottom positioning plate is fixed on the bottom surface of the lifting frame of the lifting mechanism. Positioning through holes are formed on the left, middle and rear parts of the bottom positioning plate.

[0008] The horizontal beam of the mounting base to be processed is placed on the top surface of the top plate of the processing platform and fixed. The left, middle and right sides of the top surface of the horizontal beam of the mounting base are all pressed against the bent connecting blocks to be welded. The upper part of the bent connecting block is inserted into the corresponding through hole, and its outer side wall is close to the inner side wall of the corresponding through hole. The bent connecting block and the corresponding through hole are matched.

[0009] The lifting mechanism includes a connecting frame fixed to the middle of the top surface of the top plate of the upper support frame. An electric push rod is fixed to the bottom surface of the top plate of the connecting frame. The lower part of the sleeve of the electric push rod is inserted into a guide through hole formed in the middle of the top plate of the upper support frame. The push rod in the sleeve of the electric push rod extends out of the bottom surface of the top plate of the upper support frame and is fixed to the top surface of the lifting frame.

[0010] The lifting frame includes a rectangular frame section, and horizontal connecting plates extending forward and backward are fixed to the left, middle and right parts of the top surface of the frame section. The bottom end of the push rod of the electric push rod is fixed to the top surface of the middle horizontal connecting plate.

[0011] Vertical fixing plates are fixed to the left and right sides of the top surface of the top plate of the processing platform, and vertical fixing plates are also fixed to the left and right sides of the rear part of the top surface of the top plate of the processing platform.

[0012] The middle of each vertical fixing plate is formed with a screw-in through hole. The side adjusting screw is screwed into the screw-in through hole. The outer end of the side adjusting screw extends out of the corresponding outer side of the vertical fixing plate and is formed with a rotating part. The inner end of the side adjusting screw extends out of the vertical fixing plate and is movably connected to a pressing limit block. The horizontal beam of the mounting base is clamped between the opposite walls of the left and right pressing limit blocks.

[0013] The front ends of the two rear clamping and limiting blocks press against the rear wall of the transverse beam of the mounting base.

[0014] The outstanding effect of this utility model is:

[0015] It eliminates the need to mark the corresponding positions of the transverse beam. After positioning the transverse beam, the bent connecting block to be welded can be inserted into the corresponding through hole. The position where its bottom presses against the top surface of the transverse beam is the installation position. It can then be directly spot welded or welded to fix the entire piece. It is easy to process and has high processing efficiency. Attached Figure Description

Figures 1 to 3As shown, a positioning device for machining the mounting base of a jet fan includes a machining platform 10, and an upper support frame 20 is fixed to the top surface of the top plate of the machining platform 10. The upper support frame 20 includes a top plate and vertical support legs fixed to the bottom surface at the four corners of the top plate. The bottom ends of the vertical support legs are fixed to the front and rear parts of the left and right sides of the top surface of the top plate of the machining platform 10.

[0020] A lifting mechanism 30 is installed on the top plate of the upper support frame 20. A bottom positioning plate 40 is fixed on the bottom surface of the lifting frame 31 of the lifting mechanism 30. Positioning through holes 41 are formed on the left, middle and rear parts of the bottom positioning plate 40.

[0021] The lifting mechanism 30 includes a connecting frame 32 fixed to the middle of the top surface of the top plate of the upper support frame 20. The lower legs on the left and right sides of the connecting frame 32 are fixed to the top plate of the upper support frame 20 by bolts. The connecting frame 32 can be disassembled after the bolts are removed as needed. An electric push rod 33 is fixed to the bottom surface of the top plate of the connecting frame 32. The lower part of the sleeve of the electric push rod 33 is inserted into the guide through hole formed in the middle of the top plate of the upper support frame 20. A guide sleeve is fixed on the inner side wall of the guide through hole. The lower part of the sleeve of the electric push rod 33 is inserted into the guide sleeve, and its outer side wall is close to the inner side wall of the guide sleeve.

[0022] The push rod in the sleeve portion of the electric push rod 33 extends out of the bottom surface of the top plate of the upper support frame 20 and is fixed to the top surface of the lifting frame 31.

[0023] Furthermore, the lifting frame 31 includes a rectangular frame portion 311, and horizontal connecting plates 312 extending forward and backward are fixed to the left, middle and right parts of the top surface of the frame portion 311.

[0025] The mounting base transverse beam 100 to be processed is placed on the top surface of the top plate of the processing platform 10 and fixed. Bent connecting blocks 200 to be welded are pressed against the left, middle, and right parts of the top surface of the mounting base transverse beam 100. The upper part of the bent connecting block 200 is inserted into the corresponding through hole 41, and its outer side wall is close to the inner side wall of the corresponding through hole 41. The bent connecting block 200 mates with the corresponding through hole 41. The bent connecting block 200 is a U-shaped component, including an upper plate. Both sides of the upper plate have downwardly extending bent portions formed at their bottom. The bottom ends of the bent portions press against the top surface of the mounting base transverse beam 100 (in this embodiment, the mounting base transverse beam 100 is a cut channel steel piece).

[0026] Furthermore, vertical fixing plates 11 are fixed to the left and right sides of the top surface of the top plate of the processing platform 10, and vertical fixing plates 11 are also fixed to the left and right sides of the rear part of the top surface of the top plate of the processing platform 10.

[0027] Each vertical fixing plate 11 has a threaded through hole formed in the middle. The side adjusting screw 12 is threaded into the threaded through hole. The outer end of the side adjusting screw 12 extends out of the corresponding outer side of the vertical fixing plate 11 and has a rotating part. The inner end of the side adjusting screw 12 extends out of the vertical fixing plate 11 and is movably connected to the clamping limit block 13. The horizontal beam 100 of the mounting base is clamped between the opposite walls of the two clamping limit blocks 13 on the left and right.

[0028] The front ends of the two rear clamping and limiting blocks 13 press against the rear wall of the mounting base transverse beam 100.

[0029] Limiting protective plates 14 are fixed on the corresponding wall surface of the pressing and limiting block 13. The left and right ends of the mounting base transverse beam 100 are tightly attached to the end face of the corresponding limiting protective plate 14, and the front end face of the rear limiting protective plate 14 is pressed against the rear wall surface of the mounting base transverse beam 100. The limiting protective plate 14 can be made of nylon.

[0030] A spring 2 is inserted into the side adjusting screw 12. One end of the spring 2 presses against the corresponding vertical fixing plate 11, and the other end applies force to the outer end surface of the corresponding pressing limit block 13.

[0031] A front fixing plate 15 is fixed to the middle of the front part of the top surface of the top plate of the processing platform 10. A front electric push rod 16 is fixed to the rear wall of the front fixing plate 15. A front clamping block 17 is fixed to the rear end of the push rod of the front electric push rod 16. A first elastic limiting piece 171 is fixed to the rear wall of the front clamping block 17. The rear wall of the first elastic limiting piece 171 presses against the middle front wall of the transverse beam 100 of the mounting base.

[0032] A guide rod is fixed on the front wall of the front clamping block 17, and the guide rod is inserted into a guide sleeve fixed on the rear wall of the front fixing plate 15.

[0033] In this embodiment, all electrical components are electrically connected to the control host via electrical connection lines, and the operation is controlled by the control host. The control host in this embodiment has a conventional structure and will not be described in detail here.

[0034] This embodiment is suitable for processing a batch of mounting seats. When processing a batch of products of the same specification, the bottom positioning plate 40 with the corresponding through hole 41 is first fixed to the bottom surface of the lifting frame 31 by bolts (the length and width of the bottom positioning plate 40 shown in the attached figure of this embodiment can meet the installation needs of the longest mounting seat in the processing specification. For mounting seats shorter than this bottom positioning plate 40, it is only necessary to ensure that the position of the through hole 41 meets the processing requirements). Then, when processing the first mounting seat, the horizontal beam 100 of the mounting seat to be processed is placed on the top surface of the top plate of the processing platform 10. The corresponding side adjusting screw 12 is rotated to change the clamping limit blocks 13 on the left and right sides and the rear, so that the left and right ends of the horizontal beam 100 of the mounting seat are tightly attached to the end face of the corresponding limit protection plate 14 (that is, the horizontal beam 100 of the mounting seat can move from the left and right limit protection plates 14, but the two ends are not attached to the end face of the corresponding limit protection plate 14). The end faces of 4 are in close contact or have a very small gap, such as about 2mm, to achieve the limit). The front end face of the limit protection plate 14 at the rear presses against the rear wall surface of the mounting base transverse beam 100. Then, the bottom positioning plate 40 is pushed by the push rod of the electric push rod 33, so that it is lowered, but there is a gap between it and the mounting base transverse beam 100. The bent connecting block 200 to be welded is inserted into the corresponding through hole 41. Its bottom extends out of the through hole 41 and presses against the top surface of the mounting base transverse beam 100. At this time, first measure whether its installation position meets the design requirements. If it does not meet the requirements, the bottom positioning plate 40 needs to be lifted. Then, by rotating all the side adjustment screws 12, the position of the pressing limit block 13 is changed, thereby changing the clamping and fixing position of the mounting base transverse beam 100. After the adjustment is completed, the push rod of the front electric push rod 16 is pushed, and the rear wall surface of the first elastic limit plate 171 presses against the middle front wall surface of the mounting base transverse beam 100 to achieve the fixing of the mounting base transverse beam 100.

[0035] The bent connecting block 200 is inserted into the corresponding through hole 41, and its bottom extends out of the through hole 41 and presses against the corresponding position on the top surface of the mounting base transverse beam 100. At this time, welding can be performed. After completion, only the push rod of the electric push rod 33 needs to retract, and then the push rod of the front electric push rod 16 needs to retract to move the mounting base transverse beam 100 with the welded bent connecting block 200 out (since the left and right ends of the mounting base transverse beam 100 are at the end face of the corresponding limiting protective plate 14, it can be moved upward).

[0036] The subsequent processing of the transverse beam 100 of the mounting base only requires inserting it between the two corresponding limiting protective plates 14, pressing its rear wall against the front end surface of the rear limiting protective plate 14, and then pushing it with the push rod of the front electric push rod 16 to achieve positioning. The bottom positioning plate 40 descends and inserts the corresponding bending connecting block 200 for welding and fixing, which is very convenient.

[0037] It is suitable for welding and manufacturing large quantities of mounting bases of the same specifications. It is easy to manufacture, has good manufacturing effect, and is highly efficient.

[0038] In this embodiment, there is a gap between the through hole 41 and the bent connecting block 200. This gap error does not affect the installation position. Similarly, the gap between the end faces of the left and right limit protective plates 14 and the left and right ends of the transverse beam 100 does not affect the installation position. Both are within a controllable range.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
