Description

Technical Field

[0001] The invention belongs to the technical field of casting milling processing, and in particular relates to a casting milling processing alignment auxiliary tool. Background Art

[0002] With the rapid development of science and technology, more and more mechatronic products are being produced, and the number of shell castings is increasing. In the past, the processing of castings first required the fitter to align the markings, and then align the marking planes on the milling machine, and finally process the positioning reference planes required for subsequent processes. In the above processing procedures, on the one hand, the fitter uses a square to check the verticality of each side of the casting to check whether the placement state of the casting meets the processing requirements, which is inefficient; secondly, many concave surfaces in the inner cavity cannot be detected due to the lack of suitable shims, squares, or even special tools, resulting in problems in the subsequent casting processing; thirdly, due to the milling worker's method of aligning the fitter's markings, the alignment error is large, the processing state and the marking state of the casting cannot overlap, and problems are also likely to occur in the subsequent processing of the casting; fourthly, the casting needs to be aligned twice, which is time-consuming and labor-intensive; therefore, it is necessary to make improvements to the above problems. Summary of the invention

[0003] The technical problem solved by the present invention is as follows: It provides a casting milling alignment aid, which provides conditions for detecting and adjusting the overall state of two detected reference side walls of the casting which are supported on the base plate by height-adjustable support feet and located between the two mounting plates, and detects the vertical surface of the groove in the inner cavity of the casting by a vertical detection component installed on a telescopic cantilever and located above the casting, thereby solving the problems of low efficiency in detecting and adjusting the placement state of the casting during processing and great difficulty in detecting the concave surface of the casting, eliminating the disadvantage that the processing and marking states of the casting cannot be overlapped, reducing the difficulty of alignment, improving the alignment efficiency, reducing the alignment error, and having strong versatility. According to the size of the casting, only the distance between the reference side plates needs to be adjusted to meet the positioning requirements of the subsequent process.

[0004] The technical solution adopted by the present invention is as follows: a casting milling alignment aid, comprising a base plate, two mounting plates symmetrically arranged front and back are vertically arranged above the base plate, and the two mounting plates are adjustably mounted on the base plate in front and back positions through a guide slider device, a limiting component is provided on the base plate for limiting the extreme position of the outward movement of the mounting plate, columns fixedly connected to the outer wall of the reference side plate fixed at the inner edge of the mounting plate are symmetrically fixed on the mounting plate, and the casting, whose bottom is supported by a plurality of height-adjustable supporting feet arranged on the base plate, is located between the two reference side plates, and the casting is aligned with the cooperation of a plurality of sets of elastic pin detection components and the height-adjustable supporting feet arranged on the reference side plate; a vertical detection component for detecting the groove in its inner cavity is provided above the casting, and the vertical detection component is fixedly connected to the telescopic cantilever fixed on the worktable of the machine tool.

[0005] Among them, the guide slider device includes two guide rails symmetrically fixed on the base plate and two sliders adapted to the guide rails. The two ends of the mounting plate are fixedly connected to the sliders at the corresponding ends of the two guide rails, and the two mounting plates can slide towards or in the opposite direction with the cooperation of the guide rails and the sliders.

[0006] Furthermore, the limit assembly includes a limit block and a limit screw, and the limit blocks located between the two guide rails in the guide slider device are fixed at the front and rear edges of the upper end of the base plate, and the vertical edge of the limit block with an L-shaped structure is set outward, and the middle part of the mounting plate surface is threadedly connected to the limit screw, and the lower end of the limit screw is located on the inner side of the vertical edge of the limit block, and when the mounting plate moves to the point where the limit screw contacts the vertical edge of the limit block, the mounting plate is limited to the extreme outward position.

[0007] Furthermore, the elastic pin detection assembly includes a step pin, and the reference side plate surface is provided with a plurality of step holes whose inner end diameters are larger than their outer end diameters, and the small diameter section of the step pin is inserted into the step hole. The small diameter section of the step pin is provided with a spring having one end resting on the step surface of the step pin and the other end resting on the step surface of the inner end of the step hole. The step pin is adaptively connected to the step pin end face by a connecting screw which is arranged inside the small diameter section of the step hole and whose large head end rests on the step surface of the outer end of the step hole, thereby realizing the elastic installation of the step pin on the reference side plate. The verticality, horizontal angular state and symmetry of the two detected reference side walls of the casting are judged by the distance between the end of the small diameter section of the step pin and the outer side wall of the reference side plate.

[0008] Furthermore, the groove detection group includes a fixed plate fixed on the telescopic cantilever and arranged parallel to the base plate, a guide sleeve fixed on the fixed plate, a prism rod whose upper end has a step shaft that cooperates with the step hole of the guide sleeve and whose lower end passes through the guide sleeve and the fixed plate; the prism rod is arranged perpendicular to the base plate, and the prism rod rotates freely in the guide sleeve with the cooperation of the step hole of the guide sleeve and the step shaft at the upper end of the prism rod; a groove detection block for vertically detecting the concave surface in the inner cavity of the casting is detachably fixed on the side wall of the prism rod.

[0009] Furthermore, the groove detection block is fixed on the angular rod by a plurality of countersunk screws.

[0010] Furthermore, the casting is leveled by height-adjustable support feet, and a mold pressing plate disposed on the bottom plate and located outside the height-adjustable support feet presses and fixes the protrusions at the corners of the casting.

This technical solution uses a vertical detection component installed on a telescopic cantilever and located above the casting to detect the vertical surface of the groove in the inner cavity of the casting. It can detect the verticality of all side walls of the casting, especially the detection of the blind inner cavity and the inner concave surface of the casting, and it is no longer necessary to prepare various specifications of shims and squares and other measuring tools;

[0014] 3.

[0022] Casting milling alignment aids, such as Figure 1-2 As shown, it includes a base plate 1, two mounting plates 2 symmetrically arranged front and back are vertically arranged above the base plate 1, and the two mounting plates 2 are adjustable in front and back positions on the base plate 1 through a guide slider device, and a limiting component for limiting the extreme position of the outward movement of the mounting plate 2 is provided on the base plate 1, and columns 17 fixedly connected to the outer wall of the reference side plate 3 fixed at the inner edge of the mounting plate 2 are fixed on the mounting plate 2 symmetrically, and a casting 4 supported at the bottom by a plurality of height-adjustable supporting feet 5 arranged on the base plate 1 is located between the two reference side plates 3, and a plurality of groups of elastic pin detection components arranged on the reference side plate 3 are observed, and the casting 4 is manually moved, and the front and rear surfaces of the casting 4 are aligned with the cooperation of the height-adjustable supporting feet 5; a limiting component for aligning the casting 4 is provided above the casting 4 A vertical detection component is provided for vertical detection of the vertical side wall and the groove in the inner cavity, and the vertical detection component is fixedly connected to the telescopic cantilever fixed on the machine tool workbench; in the above structure, by arranging a mounting plate 2 which can move toward or oppositely and has multiple sets of elastic pin detection devices on the bottom plate 1, conditions are provided for detecting and adjusting the overall state of the two detected reference side walls of the casting 4 supported on the bottom plate 1 by the height-adjustable support feet 5 and located between the two mounting plates 2, and the vertical and horizontal angular states of the two main detected reference side walls of the casting 4 and the symmetry of the two faces can be conveniently and directly accurately judged, and it is not affected by the casting accuracy of the surface of the casting 4. In the process of adjusting the adjustable support feet, the placement state of the casting 4 can be observed and judged at any time, and the detection and adjustment efficiency is high;

[0023] The specific structure of the guide slider device is as follows: the guide slider device includes two guide rails 6 symmetrically fixed on the base plate 1 and two sliders 7 adapted to the guide rails 6. The two ends of the mounting plate 2 are fixedly connected to the sliders 7 at the corresponding ends of the two guide rails 6, and the two mounting plates 2 can slide towards or in the opposite direction with the cooperation of the guide rails 6 and the sliders 7. The above structure provides conditions for adjusting the distance between the two mounting plates 2, thereby meeting the use requirements of castings 4 of different sizes.

[0024] like Figure 1As shown, the specific structure of the limit assembly is as follows: the limit assembly includes a limit block 8 and a limit screw 9, and the limit blocks 8 located between the two guide rails 6 in the guide slider device are fixed at the front and rear edges of the upper end face of the base plate 1, and the vertical edge of the limit block 8 with an L-shaped structure is set outward, and the middle part of the plate surface of the mounting plate 2 is threadedly connected to the limit screw 9, and the lower end of the limit screw 9 is located on the inner side of the vertical edge of the limit block 8, and when the mounting plate 2 moves to the limit screw 9 and contacts the vertical edge of the limit block 8, the mounting plate 2 is limited to the extreme outward movement position; adopting the above structure, on the one hand, the limit screw 9 on the mounting plate 2 can limit the stroke of the slider 7, and on the other hand, when the mounting plate 2 needs to be fixed in position, tighten the limit screw 9 so that the lower end surface of the limit screw 9 contacts the corresponding position of the horizontal plate of the limit block 8, which can prevent the slider 7 from moving, play the role of fixing the mounting plate 2, facilitate operation, and effectively prevent the slider 7 from detaching from the guide rail 6.

[0025] like Figure 3 As shown, the specific structure of the elastic pin detection assembly is as follows: the elastic pin detection assembly includes a step pin 10, and a plurality of step holes 11 with inner end diameters larger than outer end diameters are formed on the surface of the reference side plate 3, and the small diameter section of the step pin 10 is inserted into the step hole 11, and the small diameter section of the step pin 10 is sleeved with a spring 18 with one end resting on the step surface of the step pin 10 and the other end resting on the step surface of the inner end of the step hole 11, and the step pin 10 is adaptively connected with the end face of the step pin 10 by a connecting screw 12 which is arranged inside the small diameter section of the step hole 11 and the large head end rests on the step surface of the outer end of the step hole 11, so as to realize the elastic installation of the step pin 10 on the reference side plate 3, and the verticality, horizontal angular state and symmetry of the two detected reference side walls of the casting 4 are judged by the distance between the end of the small diameter section of the step pin 10 and the outer side wall of the reference side plate 3; In the above structure, the vertical surface of the groove in the inner cavity of the casting 4 is detected by the vertical detection component installed on the telescopic cantilever and located above the casting 4, so that the verticality of all side walls of the casting 4 can be detected, especially the detection of the blind inner cavity and the inner concave surface of the casting 4 can be realized, and it is no longer necessary to prepare various specifications of shims, squares and other measuring tools; wherein, the elastic pin detection component can determine its position on the reference side plate 3 according to the shape and size of the main side reference surfaces before and after 4, and detect a point on the casting 4 at each position. By comparing the position of the surface of the elastic pin detection component with the outer surface of the reference side plate 3, the distance between each detection point of the casting and the inner surface of the reference side plate 3 can be determined. By comprehensively comparing the positions of the detection points on each surface, the overall state of the two side reference surfaces of the casting 4 can be judged, and adjusted through the height-adjustable support feet 5.

[0026] like Figure 1-2As shown, the specific structure of the groove detection group is as follows: the groove detection group includes a fixed plate 13 fixed on the telescopic cantilever and arranged parallel to the bottom plate 1, a guide sleeve 14 fixed on the fixed plate 13, and a stepped shaft at the upper end cooperates with the stepped hole of the guide sleeve 14 and the lower end passes through the guide sleeve 14 and the fixed plate 13. The prism 15 is arranged perpendicular to the bottom plate 1, and the prism 15 rotates freely in the guide sleeve 14 under the cooperation of the stepped hole of the guide sleeve 14 and the stepped shaft at the upper end of the prism 15. The side wall of the prism 15 is detachably fixed with a prism for detecting the concave surface in the inner cavity of the casting 4. A groove detection block 16 for vertical detection is provided; specifically, the groove detection block 16 is fixed to the prism 15 by a plurality of countersunk screws; in the above structure, the telescopic cantilever is used to enable the vertical detection component to move freely in the travel space, and the detection prism 15 can be guaranteed to be always perpendicular to the work surface. Combined with the angular rotation of the prism 15 in the guide sleeve 14, the groove detection block 16 can be processed according to the size of the casting 4 and connected to the prism 15 by screws. The prism 15 is equivalent to a vertical angle ruler that can be moved arbitrarily in space, and can realize the detection of any vertical surface of the casting 4;

[0027] Among them, the casting 4 is leveled by a height-adjustable supporting foot 5, and the height-adjustable supporting foot 5 is an existing structure and will not be described here in detail. The mold pressure plate arranged on the base plate 1 and located on the outside of the height-adjustable supporting foot 5 presses and fixes the protrusions at the corners of the casting 4 to ensure the stability and reliability of the casting 4 after leveling.

[0028] When in use, the inner end face of the step pin 10 is always in contact with the casting 4. When the surface of the casting 4 is in contact with the inner surface of the reference side plate 3, the inner end face of the step pin 10 is flush with the inner wall of the reference side plate 3, and the outer end face of the connecting screw 12 is flush with the outer wall of the reference side plate 3; when there is a distance between the surface of the casting 4 and the inner wall of the reference side plate 3, under the action of the spring 18, the step pin 10 moves inward, so that the distance between the outer end face of the connecting screw 12 moving inward and the outer wall of the reference side plate 3 is equal to the distance between the surface of the casting 4 and the inner wall of the reference side plate 3. Therefore, by observing the distance between the outer end face of the connecting screw 12 and the outer wall of the reference side plate 3, the distance between the surface of the casting 4 and the detection reference plane of the reference side plate 3 can be judged, and by observing and comparing the distances between the outer end faces of the two connecting screws 12 and the outer walls of the reference side plate 3, the inclination state of the surface of the casting 4 relative to the detection reference plane of the reference side plate 3 in these two directions can be judged.

[0029] Since the surface of the casting 4 is uneven, in order to reduce the sampling error of the detection points, we take three points in each detection straight line direction and nine points in each plane as sampling judgment detection points. Through comprehensive observation of these nine points, the inclination and symmetry of the two surfaces of the casting 4 can be judged at any time. The casting 4 can be adjusted while adjusting the height-adjustable supporting feet 5 while judging and observing. Therefore, the alignment efficiency of the casting 4 can be greatly improved; when the sizes of the left and right ends of the casting 4 are inconsistent, the two movable reference side plates 3 cannot accurately limit the angular direction of the casting 4 in the horizontal direction. At this time, the elastic pin detection assembly can be observed and the casting 4 can be manually moved for adjustment to make the distance between the two sides of the small end of the casting 4 and the reference side plates 3 equal.

[0030] In addition, due to the uneven surface of the casting 4, when in use, there is a distance between most of the detection points and the reference side plate 3. For the convenience of observation, according to practical experience, during processing, the total length of the step pin 10 and the connecting screw 12 after connection is 0.5mm larger than the thickness of the reference side plate 3. At this time, the movable range of the outer end face of the connecting screw 12 is changed from protruding 0.5mm from the outer surface of the reference side plate 3 to a distance below the outer surface of the reference side plate 3, thereby improving the observation accuracy.

[0031] The technical solution has a simple structure, reasonable design, and is convenient and quick to disassemble and assemble. It solves the problems of low efficiency in detecting and adjusting the placement state of the casting 4 during processing and difficulty in detecting the concave surface of the casting 4, eliminates the disadvantage that the processing and marking states of the casting 4 cannot overlap, reduces the difficulty of alignment, improves the alignment efficiency, reduces the alignment error, has strong versatility, and only needs to adjust the distance between the reference side plates according to the size of the casting 4 to meet the positioning requirements of the subsequent process.
