Description

Technical Field

[0001] This utility model belongs to the field of water pump flange processing technology, specifically, it relates to a quick mold changing fixture structure for water pump flanges on CNC milling machines. Background Technology

[0002] A flange is a component used to connect pipes to each other, attached to the end of the pipe; the flange has holes, bolts are used to tightly connect two flanges, and a gasket is used to seal between the flanges; a flange is a disc-shaped part, widely used in the field of water pumps and oil pumps, and is a connecting part between the pump body and the pipeline;

[0003] Machining water pump flanges on a CNC milling machine is a typical machining task that requires a combination of process planning, fixture design, tool selection, and parameter optimization to achieve high-precision and high-efficiency production.

[0004] A document with publication number (CN210305881U) discloses a drilling mold for a water pump flange. The mold includes a template and a tensioning sleeve, with the tensioning sleeve fixedly connected to the center of the template. The template has several first and second template holes evenly distributed on it. The first template holes correspond to the positions of holes on surface A of the flange, and the second template holes correspond to the positions of holes on surface B of the flange. Drilling the flange directly using the template holes ensures the accuracy of the hole positions on the flange and greatly improves production efficiency. The first and second template holes are respectively provided with first and second angle grooves. Adjusting ears are also connected to both sides of the template. By tapping the adjusting ears, the position of the template can be adjusted, thereby adjusting the first or second angle groove to the corresponding position, avoiding the problem of laborious and difficult manual adjustment.

[0005] The aforementioned device adjusts and guides the drilling position of the water pump flange. However, the processing of the water pump flange also requires deburring and other processing steps. During processing, the water pump flange needs to be clamped. The aforementioned device cannot limit the position of the water pump flange during processing. When the position of the water pump flange shifts during processing, the quality of the water pump flange is damaged.

[0006] In view of this, this utility model is proposed. Utility Model Content

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This CNC milling machine uses a quick-change fixture structure for water pump flanges.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0031] Please see Figure 1-5 A quick-change fixture structure for water pump flanges on a CNC milling machine includes a clamping assembly for clamping the water pump flange. The clamping assembly includes a base 1, clamping blocks 11, an operating table 2, and a feeding block 21. The base 1 and the operating table 2 are fixedly connected. The clamping blocks 11 are symmetrically arranged on the base 1, and each clamping block 11 is slidably connected to the base 1. The feeding block 21 is slidably connected to the operating table 2 and is drivenly connected to the clamping blocks 11. The abutment wheel 3 is roller-shaped and rotatably connected to the mounting frame 31 so that water pump flanges of different sizes can be fed to the middle of the clamping block 11. The water pump flange is continuously pushed to the middle of the clamping block 11, and the edge of the water pump flange is in close contact with the friction block 12. The friction force of the friction block tightly clamps the water pump flange, restricting the position of the water pump flange and ensuring that the position of the water pump flange is fixed during processing, avoiding the problem of processing position deviation.

[0032] Each clamping block 11 is fixedly connected to a friction block 12, and the friction block 12 has an arc groove in the middle. Each clamping block 11 is symmetrically provided with an abutment wheel 3 and a sliding rod 32. Each sliding rod 32 is slidably connected to the clamping block 11, and the end of each sliding rod 32 is fixedly connected to a mounting frame 31. The corresponding abutment wheel 3 is rotatably connected to the mounting frame 31. Each sliding rod 32 is fitted with a second spring 33, and the end of each second spring 33 is fixedly connected to the corresponding clamping block 11 and the mounting frame 31. When the water pump flange is pushed between the clamping blocks 11, the edge of the water pump flange first contacts the abutment wheel 3, and the water pump flange pushes the abutment wheel. 3. The abutment wheel 3 drives the mounting frame 31 to compress the second spring 33. After being compressed, the second spring 33 deforms and applies the deformation force to the abutment wheel 3, making the abutment wheel 3 in close contact with the edge of the water pump flange. During the movement of the water pump flange, the abutment wheel 3 is roller-shaped and rotatably connected to the mounting frame 31, so that water pump flanges of different sizes can be sent to the middle of the clamping block 11. The water pump flange is continuously pushed to the middle of the clamping block 11, and the edge of the water pump flange is in close contact through the friction block 12. In close contact, the water pump flange is tightly clamped by friction, which restricts the position of the water pump flange and ensures that the position of the water pump flange is fixed during processing, avoiding the problem of processing position deviation.

[0033] The base 1 has a guide groove 4 fixedly connected to its bottom, and a transmission block 41 is slidably connected to the guide groove 4. The feeding block 21 is adjustablely connected to the transmission block 41. The transmission block 41 has symmetrically arranged transmission rods 44 in an array. The end of each transmission rod 44 is rotatably connected to the corresponding transmission block 41, and the other end of each transmission rod 44 is rotatably connected to the corresponding clamping block 11. The base 1 has corresponding recessed holes, and the rotatable connection between the transmission rods 44 and the clamping blocks 11 passes through these recessed holes. After the water pump flange is placed on the operating table 2, the feeding block 21 is manually pushed, pushing the water pump flange onto the base 1. The feeding block 21, through a component at its bottom, drives the transmission block 41 to move, and the transmission block 41, in its movement, drives the corresponding... The transmission rod 44 rotates at one end and restricts the movement trajectory of the other end of the transmission rod 44 through the recess on the base 1. This allows the clamping blocks 11 on both sides to move as the transmission block 41 moves, driven by the transmission rod 44. As the feeding block 21 is pushed toward the base 1, the clamping blocks 11 are driven to move inward synchronously and clamp the water pump flange through the components on the clamping blocks 11. After the previous water pump flange is processed, the feeding block 21 is pulled back, and the clamping blocks 11 are separated. After separation, the new water pump flange is placed on the operating table 2. The operating table 2 is pushed again to push the new water pump flange onto the base 1, and the processed water pump flange is pushed out. This allows for the loading and unloading of the water pump flange through pushing and pulling, enabling the rapid replacement of the water pump flange.

[0034] The transmission block 41 is rotatably connected to a lead screw 42, which is threadedly connected to a sliding block 43. The sliding block 43 is slidably connected to the transmission block 41. A support column 22 is fixedly connected to the sliding block 43, which is fixedly connected to the feeding block 21. When the lead screw 42 is manually rotated, it drives the sliding block 43 to move through the thread. The sliding block 43 drives the support column 22, which in turn drives the feeding block 21. This changes the distance between the feeding block 21 and the edge of the base 1. By changing the position of the feeding block 21, it adapts to water pump flanges of different sizes, preventing the water pump flange size from exceeding the distance between the feeding block 21 and the base 1, which would otherwise prevent the water pump flange from being fed onto the base 1 by the feeding block 21.

[0035] The support column 22 has symmetrically arranged sliding grooves, and each sliding groove has a slidably connected locking block 23. A first spring 24 is symmetrically arranged between the sliding groove and the locking block 23. The end of each first spring 24 is fixedly connected to the corresponding locking block 23 and the groove. Each locking block 23 is U-shaped, and the operating table 2 has a corresponding locking slot. The corresponding locking block 23 engages with the locking slot. After the feeding block 21 slides to the appropriate position, the locking block 23 engages with the locking slot. The position of the support column 22 is restricted, and the position of the transmission block 41 is restricted by the support column 22 to prevent the clamping block 11 from loosening during clamping. The locking block 23 is pressed manually, and the locking block 23 compresses the first spring 24, separating the locking block 23 from the slot. The feeding block 21 is pulled manually to move the support column 22. When the locking block 23 is aligned with the slot again during the movement of the support column 22, the first spring 24 applies the deformation force to the locking block 23, locking the locking block 23 into the slot.

[0036] It is worth noting that this optimization scheme addresses the positional limitations in the machining of water pump flanges and aims to achieve rapid loading and unloading of water pump flanges. Therefore, it does not disclose the CNC milling machine component in detail. Furthermore, CNC milling machines are existing, mature technologies, and have been fully disclosed in publication number CN222386460U, which describes a vertical CNC milling machine. This machine includes a CNC milling machine structure with an internal waste removal structure. The CNC milling machine structure includes a base, a column on the top left of the base, a fixing box on the top of the column, and a motor housing on the top of the fixing box. The bottom of the fixed box is equipped with a lifting slide, the right side of the lifting slide is equipped with a milling head, the bottom of the milling head is equipped with a worktable, and the left side of the worktable is equipped with a waste cleaning device. This vertical CNC milling machine can effectively suck up waste through the use of the waste cleaning device, avoiding the scattering and pollution of waste, and improving the cleanliness and safety of the processing environment. At the same time, through the use of transmission devices such as lead screws and slides, the milling head can be moved precisely and the stability of the milling head during the processing can be guaranteed. The optimized solution is installed in a suitable position on the CNC milling machine, which will not be described in detail here.

[0037] Working principle: After placing the water pump flange on the operating table 2, the feeding block 21 is manually pushed. The feeding block 21 pushes the water pump flange towards the base 1. The feeding block 21 drives the transmission block 41 to move through the bottom component transmission. During the movement, the transmission block 41 drives the corresponding transmission rod 44 to rotate. The movement trajectory of the other end of the transmission rod 44 is restricted through the concave hole on the base 1. As the transmission block 41 moves, the clamping blocks 11 on both sides are driven to move through the transmission rod 44. As the feeding block 21 is pushed towards the base 1, the clamping blocks 11 are driven to move inward synchronously and clamp the water pump flange through the components on the clamping blocks 11. After the previous water pump flange is processed, the feeding block 21 is pulled back. The clamping blocks 11 separate, and after separation, the new water pump flange is placed on the operating table 2. The operating table 2 is pushed again to push the new water pump flange onto the base 1, and the processed water pump flange is pushed out, realizing the loading and unloading of the water pump flange through pushing and pulling, and realizing the quick replacement of the water pump flange. When the water pump flange is pushed between the clamping blocks 11, the edge of the water pump flange first contacts the abutment wheel 3. The water pump flange pushes the abutment wheel 3, and the abutment wheel 3 drives the mounting frame 31 to compress the second spring 33. The second spring 33 deforms after being compressed and applies the deformation force to the abutment wheel 3, making the abutment wheel 3 in close contact with the edge of the water pump flange. During the movement of the water pump flange, the abutment wheel 3 is roller-shaped and in contact with the mounting frame 3. 1. A rotary connection allows pump flanges of different sizes to be fed to the center of the clamping block 11. The pump flange is continuously pushed to the center of the clamping block 11, and the friction block 12 makes tight contact with the edge of the pump flange. The friction force tightly clamps the pump flange, restricting its position and ensuring that the pump flange is fixed in position during processing, avoiding the problem of processing position deviation. After the feeding block 21 slides to the appropriate position, the locking block 23 engages with the slot to restrict the position of the support column 22. The support column 22 restricts the position of the transmission block 41, preventing the clamping block 11 from loosening during clamping. When the locking block 23 is pressed manually, the locking block 23 compresses the first spring 24, and the locking is completed. Block 23 separates from the slot. Manually pulling the feeding block 21 moves the support column 22. When the locking block 23 aligns with the slot again during the movement of the support column 22, the first spring 24 applies deformation force to the locking block 23, locking the locking block 23 with the slot. Manually rotating the screw 42 causes the sliding block 43 to move through the thread during rotation. The sliding block 43 moves the support column 22 during movement, and the support column 22 moves the feeding block 21, changing the distance between the feeding block 21 and the edge of the base 1. By changing the position of the feeding block 21, different sizes of water pump flanges are adapted to avoid the water pump flange size exceeding the distance between the feeding block 21 and the base 1, which would prevent the water pump flange from being fed onto the base 1 by the feeding block 21.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
