[0004] In order to improve the machining precision of the mixing chamber, the present application provides a clamping tool for a mixing chamber.

[0005] The clamping tool for a mixing chamber provided by the present application adopts the following technical scheme:

[0006] A clamping tool for a mixing chamber, comprising a rack, an installation plate rotatably installed on the top surface of the rack, a clamping mechanism installed on the top surface of the installation plate, and a turnover mechanism for driving the installation plate to horizontally turn over; the clamping mechanism comprises an installation block arranged on the top surface of the installation plate, a clamping block for pressing the mixing chamber against the installation block, and a driving assembly for driving the clamping block to act; the top surface of the installation block has an arrangement groove for arranging the mixing chamber, and the arrangement groove comprises limiting grooves arranged circumferentially and used for arranging the mounting lugs.

[0007] By adopting the technical scheme, in the processing of the mixing chamber, the mixing chamber is first arranged in the arrangement groove on the top surface of the mounting block, and the mounting protrusion of the mixing chamber is arranged in the limiting groove, thereby helping to limit the mixing chamber arranged in the mounting block, the mixing chamber is pressed in the arrangement groove of the mounting block by the driving assembly of the clamping mechanism, thereby processing the mounting hole of the mixing chamber, and the mounting plate is horizontally flipped by the flipping mechanism, so that the conveying pipe of the mixing chamber is in a state of being perpendicular to the top surface of the rack, thereby helping to process the inner wall of the conveying pipe of the mixing chamber. Through the cooperation between the arrangement groove in the mounting block and the clamping mechanism, the probability of movement of the mixing chamber during processing is reduced, thereby improving the processing precision of the mixing chamber.

[0008] Optionally, the arrangement groove comprises a first groove body and a second groove body in a direction towards the mounting plate, an outer diameter of the first groove body is greater than an outer diameter of the second groove body, and the outer diameter of the second groove body is smaller than a diameter of the inner side plate, and the first groove body has an abutting surface for the bottom surface of the outer side plate to abut against.

[0009] By adopting the technical scheme, the specific structure of the arrangement groove is disclosed, and the bottom surface of the outer side plate of the mixing chamber can abut against the first groove body through the arrangement of the first groove body, thereby reducing the probability of movement of the mixing chamber during processing, and improving the processing precision of the mixing chamber. The outer diameter of the first groove body is greater than the outer diameter of the second groove body, and the outer diameter of the second groove body is smaller than the inner diameter of the inner side plate, so that the debris generated in the processing of the conveying pipe can fall into the second groove body, thereby reducing the probability of scratches on the inner wall of the conveying pipe caused by the debris in the conveying pipe.

[0010] Optionally, the bottom surface of the first groove body is provided with a guide groove, the guide groove and the limiting groove are arranged one by one, the width of the guide groove is greater than the width of the limiting groove, and an arc surface is formed at the connection between the guide groove and the limiting groove.

[0011] By adopting the technical scheme, the arrangement of the guide groove helps to provide guidance for the installation of the mixing chamber in the arrangement groove, and improves the clamping efficiency of the mixing chamber in the clamping tool of the mixing chamber. The arrangement of the arc surface at the connection between the guide groove and the limiting groove helps to reduce the probability of damage of the mixing chamber caused by the collision between the guide groove and the limiting groove during clamping.

[0012] Optionally, the bottom surface of the second groove body is provided with an abutting boss for the bottom surface of the inner ring part to abut against.

[0013] By adopting the technical scheme, the arrangement of the abutting boss can provide support force for the bottom surface of the inner ring part, thereby further improving the stability of the mixing chamber arranged in the arrangement groove, reducing the probability of movement of the mixing chamber during processing, and effectively improving the processing precision of the mixing chamber.

[0014] Optionally, the bottom surface of the second groove body is provided with a positioning column extending upward and matched with the tapered groove, and the top of the positioning column is provided with a tapered protrusion matched with the tapered groove.

[0015] By adopting the technical scheme, the positioning column is arranged to improve the clamping efficiency of the mixing chamber in the clamping tool of the mixing chamber. When the positioning column is matched with the tapered groove of the mixing chamber, the bottom surface of the clamping block abuts against the top surface of the annular plate during clamping of the mixing chamber by the clamping block, so that the delivery pipe of the mixing chamber does not interfere with the clamping effect of the clamping mechanism. The tapered protrusion at the top of the positioning column helps to improve the stability of the matching between the positioning column and the tapered groove of the mixing chamber.

[0016] Optionally, the driving assembly is symmetrically arranged on both sides of the mounting block, and the driving assembly comprises a driving cylinder mounted on the top surface of the mounting plate, a mounting seat mounted on the piston rod of the driving cylinder and used for hinged matching with the clamping block, and a transmission linkage connecting the driving cylinder and the clamping block.

[0017] By adopting the technical scheme, the specific structure of the driving assembly is disclosed. The piston rod of the driving cylinder is pushed upward to drive the clamping block hinged with the mounting seat to press downward, so as to clamp the mixing chamber arranged in the arrangement groove, thereby reducing the probability of movement of the mixing chamber during processing and improving the processing precision of the mixing chamber.

[0018] Optionally, the overturning mechanism comprises a first rotating seat rotatably mounted on the top surface of the rack, a rotating motor used for driving the first rotating seat to rotate horizontally, and a second rotating seat rotatably mounted on the top surface of the rack; one side of the mounting plate is connected to the first rotating seat and the other side is connected to the second rotating seat, and the rotation axis of the first rotating seat coincides with the rotation axis of the second rotating seat.

[0019] By adopting the technical scheme, the specific structure of the overturning mechanism is disclosed. The first rotating seat is driven to rotate horizontally by the driving motor, and the horizontal rotation of the second rotating seat is driven by the mounting plate connecting the first rotating seat and the second rotating seat, so as to realize the overturning of the mounting plate. The coincidence of the rotation axis of the first rotating seat and the rotation axis of the second rotating seat helps to ensure the stable overturning of the mounting plate, thereby improving the processing precision and processing efficiency of the mixing chamber.

[0020] Optionally, the top surface of the mounting plate is provided with at least four groups of the mounting block and the driving assembly matched with the mounting block along the length direction of the mounting plate.

[0021] By adopting the technical scheme, at least four groups of the mounting block and the driving assembly matched with the mounting block are arranged on the top surface of the mounting plate along the length direction of the mounting plate, which helps to improve the processing efficiency of the mixing chamber by the clamping tool of the mixing chamber.

DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying drawings. Figures 1-6 The application is further described in detail.

[0034] The application discloses a clamping tool for a mixing chamber. Referring to Figure 3 The clamping tool for the mixing chamber comprises a rack 2, a mounting plate 3 rotatably mounted on the top surface of the rack 2, a clamping mechanism 4 mounted on the top surface of the mounting plate 3, and an overturning mechanism 5 for driving the mounting plate 3 to overturn horizontally.

[0035] Referring to Figure 3 and Figure 4 The clamping mechanism 4 is used for clamping and fixing the mixing chamber 1. The clamping mechanism 4 comprises a mounting block 41 arranged on the top surface of the mounting plate 3, a clamping block 42 for pressing the mixing chamber 1 against the top surface of the mounting plate 3, and a driving assembly 43 for driving the clamping block 42 to act.

The top surface of the mounting block 41 is provided with an arrangement groove 411 for arranging the mixing chamber 1. The arrangement groove 411 comprises a first groove body 4111, a limiting groove 4112 connected to the first groove body 4111 and extending towards the mounting block 41, and a second groove body 4113 connected to the first groove body 4111 near the side of the mounting plate 3.

[0036] Referring to Figure 4The limiting grooves 4112 are arranged circumferentially and are used for arranging the mounting lugs 1121 of the mixing chamber 1, which helps to limit the mixing chamber 1. The outer diameter of the first groove body 4111 is greater than the outer diameter of the second groove body 4113, so that a stepped surface is formed at the connection of the first groove body 4111 and the second groove body 4113. The outer diameter of the second groove body 4113 is smaller than the inner diameter of the inner side plate 113 of the mixing chamber 1, so that the debris generated during machining of the delivery pipe 13 will fall into the second groove body 4113, reducing the probability of debris accumulation in the delivery pipe 13 causing damage to the inner wall of the delivery pipe 13.

[0037] The bottom surface of the first groove body 4111 has an abutting surface 41111 for abutting the bottom of the outer side plate 112 of the mixing chamber 1, and the bottom surface of the second groove body 4113 is provided with an abutting boss 412 for abutting and cooperating with the bottom surface of the inner ring part 12. The bottom surface of the second groove body 4113 is also provided with a positioning column 413 extending upward and cooperating with the tapered groove 1221 of the mixing chamber 1, and the top of the positioning column 413 has a tapered convex part 4131 cooperating with the tapered groove 1221, which helps to position the mixing chamber 1 arranged in the arrangement groove 411 and improves the clamping efficiency of the mixing chamber 1 in the clamping tool of the mixing chamber.

[0038] Referring to Figure 4 and Figure 5 The bottom surface of the first groove body 4111 is also provided with a downwardly recessed guide groove 414, and the guide groove 414 is arranged one-to-one with the limiting groove 4112. The width of the guide groove 414 is greater than the width of the limiting groove 4112, so that the connection between the guide groove 414 and the limiting groove 4112 forms an arc surface 415, and the arrangement of the arc surface 415 helps to reduce the probability of damage to the mixing chamber 1 during clamping.

[0039] Referring to Figure 3 and Figure 6The driving assembly 43 is arranged on both sides of the mounting block 41. The driving assembly 43 comprises a driving cylinder 431 mounted on the top surface of the mounting plate 3, a mounting seat 432 mounted on the piston rod of the driving cylinder and used for hinged cooperation with the clamping block 42, and a transmission linkage 433 for transmission connection between the driving cylinder 431 and the clamping block 42. The mounting seat 432 is arranged on the top surface of the piston rod of the driving cylinder 431. The transmission linkage 433 comprises a transmission block 4331 mounted on the top surface of the driving cylinder and a transmission rod 4332 hingedly connected to the top surface of the transmission block 4331 and extending upward. The transmission rod 4332 is hingedly connected to the clamping block 42, and the hinged point of the clamping block 42 and the transmission rod 4332 is located on the side of the clamping block 42 close to the hinged point of the clamping block 42 and the mounting seat 432. The top surface of the mounting plate 3 is uniformly spaced in the length direction of the mounting plate 3 to be provided with at least four groups of the mounting block 41 and the driving assembly 43 matched with the mounting block 41. In the embodiment, the number of the mounting block 41 on the top surface of the mounting plate 3 is four, and the number of the driving assembly 43 matched with the mounting block 41 is four.

[0040] With reference to Figure 3 The overturning mechanism 5 comprises a first rotating seat 51 rotatably mounted on the top surface of the rack 2, a driving motor for driving the first rotating seat 51 to horizontally rotate, and a second rotating seat 53 rotatably mounted on the top surface of the rack 2 and arranged opposite to the first rotating seat 51. The rotation axis of the first rotating seat 51 coincides with the rotation axis of the second rotating seat 53. The first rotating seat 51 has a first connecting plate 511 for fixing one side of the mounting plate 3, and the second rotating seat 53 has a second connecting plate 531 for fixing the other side of the mounting plate 3. The mounting plate 3 is connected between the first connecting plate 511 and the second connecting plate 531 to realize horizontal overturning.

[0041] The implementation principle of the clamping tool of the mixing chamber in the embodiment of the application is as follows: during the processing of the mixing chamber 1, first, the mixing chamber 1 is placed in the arrangement groove 411 of the mounting block 41. At this time, the mounting protrusion 1121 of the mixing chamber 1 is arranged in the limiting groove 4112, and the bottom surface of the inner ring part 12 of the mixing chamber 1 abuts against the top surface of the abutting boss 412, so as to limit the mixing chamber 1 arranged in the arrangement groove 411. Then, the driving assembly 43 in the clamping mechanism 4 drives the clamping block 42 to press the mixing chamber 1 in the arrangement groove 411 of the mounting block 41, and the mounting hole 1211 of the mixing chamber 1 is processed. Then, the mounting plate 3 is driven by the overturning mechanism 5 to horizontally overturn, so as to facilitate the processing of the inner wall of the delivery pipe 13 of the mixing chamber 1. Through the cooperation between the arrangement groove 411 in the mounting block 41 and the clamping mechanism 4, the probability of the mixing chamber 1 moving in the processing process is effectively reduced, and the processing precision of the mixing chamber 1 is improved.

[0042] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
