Description

Technical Field

[0001] The present application relates to the field of casting processing equipment, and in particular to a positioning mechanism for casting processing. Background Art

[0002] During the daily processing and production of castings, when welding is required, the castings are often positioned through a corresponding positioning device to effectively ensure the stability of the castings during the welding process, thereby effectively ensuring the quality and efficiency of the welding of the castings.

[0003] Especially for pump casing castings, the pump casing is usually composed of an outer shell and a base, and the base is assembled at the bottom of the outer shell. When the outer shell of the pump casing needs to be welded together with other workpieces, the outer shell is often clamped and positioned by a positioning fixture. In specific operations, the fixture clamps the outer shell around the side, and then welds the workpiece and the outer shell together.

[0004] In this positioning method, after the fixture clamps the peripheral side of the shell, when the upper and lower sides of the shell are welded to other workpieces, if other workpieces still need to be welded to the peripheral side of the shell, in this state, since the positioning device is clamped on the peripheral side of the shell, this will hinder the welding of the peripheral side of the shell with other workpieces. At this time, it is necessary to remove the positioning device and re-clamp other parts of the pump shell so that the peripheral side of the shell can be clamped with other workpieces. This positioning method is very cumbersome and inconvenient.

[0005] At present, in order to facilitate welding of the outer shell on the pump casing with other workpieces, most of the methods adopted are often to clamp the positioning fixture directly on the base at the bottom of the pump casing, so that the outer shell will be completely exposed, thereby facilitating welding of the outer shell with other workpieces.

[0006] However, there are many types of castings such as pump casings, and different types of pump casings have different specifications, sizes and shapes of their bases. This requires that different positioning devices need to be replaced to adapt to different types of pump casing bases when clamping and positioning different types of pump casings. As a result, the steps for positioning different types of pump casings are cumbersome and inefficient, which is not conducive to the daily processing and production of pump casings. Summary of the invention

[0007] The present application provides a positioning mechanism for casting processing, the purpose of which is to facilitate the processing and positioning of different types of castings, thereby helping to improve the efficiency of daily processing and production of different types of castings.

[0008] The present application provides a positioning mechanism for casting processing, which adopts the following technical solution:

[0009] A positioning mechanism for casting processing includes a base, and two clamps are slidably arranged at the left and right ends of the base, and the two clamps are used to clamp and position the casting; the clamp is composed of an integrally formed clamping block and a supporting block, and an arc groove is provided on the side where the two clamping blocks are close to each other, and the supporting block is integrally formed at the bottom of the arc groove.

[0010] By adopting the above technical solution, when clamping the casting, the two clamps are slid toward the casting until the circumference of the casting is clamped between the arc grooves of the two clamping blocks, and the two support blocks are stably supported at the bottom of the casting, so as to further ensure the stability of the casting during welding. This setting method sets the two clamps in a sliding installation mode, so that the two clamps can clamp and position castings of different sizes, which is conducive to improving the overall adaptability of the positioning mechanism, thereby effectively ensuring the efficiency of daily processing of castings.

[0011] Preferably, the base is provided with a slide groove along its length direction, and the bottoms of the two clamping blocks are integrally formed with a slide seat, and the two slide seats are slidably installed in the slide groove.

[0012] By adopting the above technical solution, the sliding groove and the sliding seat are used to realize the sliding movement of the clamp on the base.

[0013] Preferably, guide grooves are provided on both sides of the inner wall of the slide groove along the length direction of the base, and the guide grooves are provided in plurality, and the plurality of guide grooves are evenly spaced in the vertical direction; a plurality of guide rods are integrally formed on the left and right sides of the slide seat along its length direction, and the plurality of guide rods are evenly spaced in the vertical direction, and the plurality of guide rods correspond one-to-one to the plurality of guide grooves, and the guide rods are slidably inserted into the corresponding guide grooves.

[0014] By adopting the above technical solution, when the slide slides in the slide groove, these guide rods and guide grooves can guide the slide during the sliding process of the slide, which is beneficial to ensure the stability of the slide sliding in the slide groove.

[0015] Preferably, sealing grooves are provided on the top of the base on both the left and right sides of the slide groove, and a sealing plate is fastened between the two sealing grooves in the horizontal direction.

[0016] By adopting the above technical solution, after the two slides are installed in the slide groove, the sealing plate seals the ends of the two slides, which helps to prevent external dust from entering the slide groove and affecting the sliding stability of the slide in the slide groove.

[0017] Preferably, a positioning assembly is provided on the top of each of the two slide seats, and the slide seat is used to drive the positioning assembly to slide in the slide groove; the positioning assembly includes a mounting plate and a plurality of positioning rods, and the positioning rods are movably inserted into the mounting plate along a direction perpendicular to the mounting plate, and the plurality of positioning rods are evenly spaced and distributed throughout the entire mounting plate, and the plurality of positioning rods are used to form a cavity that is compatible with the casting, and the cavity is used to position the casting; the mounting plate is composed of two plate bodies arranged at intervals, and the two plate bodies are fixed by fasteners.

[0018] By adopting the above technical solution, when the casting is processed, the two slides slide towards each other under the drive of the cylinder, and as the slides slide, the positioning rods on the mounting plate slide towards the casting. When the side wall of the casting abuts against the positioning rods, the positioning rods in contact with the casting will be squeezed by the casting, causing the positioning rods to slide on the mounting plate in a direction away from the casting.

[0019] As the slide continues to slide towards the casting, the casting will continue to squeeze the positioning rods in contact with it, and these squeezed positioning rods will gradually form cavities with the positioning rods on the surrounding sides that are not squeezed by the casting, and the casting will be stuck in the cavity. When the surrounding side of the casting is stuck in the cavity, the slide stops. In this state, the surrounding side of the casting will be covered by the cavities on its left and right sides, and the positioning rods distributed on the left and right sides of the casting will clamp and position the casting.

[0020] In this arrangement, the cavity itself has no specific size and shape. The specific size and shape of the cavity is determined by the size and shape of the casting itself. For example, a round casting will form a round cavity after squeezing the positioning rods on the mounting plate; a square casting will form a square cavity.

[0021] Even for irregular-shaped castings, if conventional positioning fixtures are used, it is necessary to specially make fixtures that match the castings, which is very troublesome. However, the above positioning method, when facing irregular-shaped castings, will form irregular-shaped cavities that match the castings, and then when facing castings of different sizes and shapes, the positioning assembly can quickly and efficiently position the castings, thereby significantly improving the efficiency of daily processing and production of different types of castings.

[0022] Preferably, a limiting plate is provided on a side of the mounting plate away from the positioning rod.

[0023] By adopting the above technical solution, a certain space is reserved between the limit plate and the mounting plate for the positioning rod to slide. During the sliding process of the positioning rod, the limit plate can effectively prevent the positioning rod from sliding out of the mounting plate, thereby playing a certain limiting role in the sliding of the positioning rod.

[0024] Preferably, the limiting plate is transparent.

[0025] By adopting the above technical solution, the limit plate is set to be transparent, and the staff can observe the positioning effect of the casting through the limit plate, which helps the staff to grasp the positioning of the casting at any time and is more convenient to use.

[0026] Preferably, the limiting plate is slidably arranged in a direction approaching or moving away from the mounting plate.

[0027] By adopting the above technical solution, this setting mode sets the limit plate as a sliding installation mode. When both ends of the casting are positioned, one of the limit plates is slid toward the mounting plate, and the limit plate squeezes the positioning rod, so that the casting inserted into the cavity is translated toward the other side under the drive of the positioning rod. Then, the position of the entire casting can be adjusted, making the casting more convenient during welding.

[0028] Preferably, a moving groove is formed on the side wall of the fastener along its length direction, and a moving block adapted to the moving groove is integrally formed at the connection between the limiting plate and the fastener, and the moving block is slidably installed in the moving groove.

[0029] By adopting the above technical solution, the sliding movement of the limit plate on the fastener is achieved by utilizing the moving groove and the moving block.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. Specifically, when clamping the casting, slide the two clamps toward the casting until the circumference of the casting is clamped between the arc grooves of the two clamping blocks, and the two support blocks are stably supported at the bottom of the casting to further ensure the stability of the casting during welding. This setting method sets the two clamps in a sliding installation mode, so that the two clamps can clamp and position castings of different sizes, which is conducive to improving the overall adaptability of the positioning mechanism, thereby effectively ensuring the efficiency of daily processing of castings. ;

[0032] 2. When the casting is being processed, the two slides slide towards each other under the drive of the cylinder. As the slides slide, the positioning rods on the mounting plate slide towards the casting. When the side walls of the casting abut against the positioning rods, the positioning rods in contact with the casting will be squeezed by the casting, causing the positioning rods to slide on the mounting plate away from the casting.

[0033] As the slide continues to slide towards the casting, the casting will continue to squeeze the positioning rods in contact with it, and these squeezed positioning rods will gradually form cavities with the positioning rods on the surrounding sides that are not squeezed by the casting, and the casting will be stuck in the cavity. When the surrounding side of the casting is stuck in the cavity, the slide stops. In this state, the surrounding side of the casting will be covered by the cavities on its left and right sides, and the positioning rods distributed on the left and right sides of the casting will clamp and position the casting.

[0034] In this arrangement, the cavity itself has no specific size and shape. The specific size and shape of the cavity is determined by the size and shape of the casting itself. For example, a round casting will form a round cavity after squeezing the positioning rods on the mounting plate; a square casting will form a square cavity.

[0035] Even for irregular-shaped castings, if conventional positioning fixtures are used, it is necessary to specially make fixtures that match the castings, which is very troublesome. However, the above positioning method, when facing irregular-shaped castings, will form irregular-shaped cavities that match the castings, and then when facing castings of different sizes and shapes, the positioning assembly can quickly and efficiently position the castings, thereby significantly improving the efficiency of daily processing and production of different types of castings;

[0036] 3. Set the limit plate to the sliding installation mode. When both ends of the casting are positioned, slide one of the limit plates toward the mounting plate and squeeze the positioning rod through the limit plate, so that the casting inserted into the cavity moves horizontally toward the other side under the drive of the positioning rod. Then the position of the entire casting can be adjusted, making the casting more convenient during welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0043] Embodiment 1:

[0044] The present application embodiment discloses a positioning mechanism for casting processing, referring to Figure 1 , including a base 1, the base 1 is in a "T"-shaped structure as a whole, and two clamps 2 are slidably arranged at the left and right ends of the top of the base 1. When the casting is processed and welded, the two clamps 2 are used to clamp and position the casting. The clamp 2 is composed of an integrally formed clamping block 21 and a support block 22. The two clamping blocks 21 are both provided with an arc groove 3 on one side close to each other, and the support block 22 is integrally formed at the bottom of the arc groove 3 in the horizontal direction.

[0045] Specifically, when clamping the casting, the two clamps 2 are slid toward the casting until the circumference of the casting is clamped between the arc grooves 3 of the two clamping blocks 21, and the two support blocks 22 are stably supported at the bottom of the casting to further ensure the stability of the casting during welding. This setting method sets the two clamps 2 in a sliding installation mode, so that the two clamps 2 can clamp and position castings of different sizes, which is conducive to improving the overall adaptability of the positioning mechanism, thereby effectively ensuring the efficiency of daily processing of castings.

[0046] Specifically, refer to Figure 1 The base 1 is provided with a slide groove 4 along its length direction, and the bottoms of the two clamping blocks 21 are integrally formed with a slide seat 5 adapted to the slide groove 4, and the two slide seats 5 are slidably installed in the slide groove 4. The slide groove 4 and the slide seat 5 are used to realize the sliding movement of the clamp 2 on the base 1.

[0047] Further, refer to Figure 1, both sides of the inner wall of the slide groove 4 are provided with guide grooves 6 along the length direction of the base 1, and the guide grooves 6 are provided in plurality, and these guide grooves 6 are evenly spaced in the vertical direction. At the same time, both left and right sides of the slide seat 5 are integrally formed with a plurality of guide rods 7 along the length direction thereof, and these guide rods 7 are evenly spaced in the vertical direction. These guide rods 7 correspond to the guide grooves 6 one by one, and the guide rods 7 are slidably inserted in the corresponding guide grooves 6.

[0048] When the slide 5 slides in the slide groove 4 , the guide rods 7 and the guide grooves 6 can guide the slide 5 during the sliding process of the slide 5 , thereby facilitating the stability of the slide 5 in sliding in the slide groove 4 .

[0049] Further, refer to Figure 1 The top of the base 1 is provided with sealing grooves 8 on both sides of the left and right sides of the slide groove 4, and a sealing plate 9 is fastened horizontally between the two sealing grooves 8 by fastening bolts. After the two slide seats 5 are installed in the slide groove 4, the sealing plate 9 seals the ends of the two slide seats 5, thereby preventing external dust from entering the slide groove 4 and affecting the stability of the slide seat 5 sliding in the slide groove 4.

[0050] The implementation principle of a positioning mechanism for casting processing in the embodiment of the present application is as follows:

[0051] Specifically, when clamping the casting, the two clamps 2 are slid toward the casting until the circumference of the casting is clamped between the arc grooves 3 of the two clamping blocks 21, and the two support blocks 22 are stably supported at the bottom of the casting to further ensure the stability of the casting during welding. This setting method sets the two clamps 2 in a sliding installation mode, so that the two clamps 2 can clamp and position castings of different sizes, which is conducive to improving the overall adaptability of the positioning mechanism, thereby effectively ensuring the efficiency of daily processing of castings.

[0052] Embodiment 2:

[0053] The difference between the embodiment of the present application and embodiment 1 is that:

[0054] Reference Figure 1 and Figure 2 The top of the two slides 5 is provided with a positioning assembly 10, and the slides 5 are used to drive the corresponding positioning assembly 10 to slide in the slide groove 4. The positioning assembly 10 includes a mounting plate 101 and a plurality of positioning rods 102. The mounting plate 101 is in a rectangular parallelepiped shape, and the mounting plate 101 is vertically arranged. The positioning rods 102 are movably inserted on the mounting plate 101 in a direction perpendicular to the mounting plate 101, and the plurality of positioning rods 102 are evenly spaced and distributed throughout the entire mounting plate 101.

[0055] When the casting is being processed, the two slides 5 slide towards each other under the drive of the cylinder, and as the slides 5 slide, the positioning rods 102 on the mounting plate 101 slide towards the casting. When the side wall of the casting abuts against the positioning rods 102, the positioning rods 102 in contact with the casting will be squeezed by the casting, causing the positioning rods 102 to slide on the mounting plate 101 away from the casting.

[0056] Reference Figure 1 , Figure 2 as well as Figure 3 As the slide 5 continues to slide toward the casting, the casting will continue to squeeze the positioning rods 102 in contact with it, and the squeezed positioning rods 102 will gradually form cavities 11 with the positioning rods 102 on the periphery that are not squeezed by the casting, and the casting will be stuck in the cavity 11. When the periphery of the casting is stuck in the cavity 11, the slide 5 stops. In this state, the periphery of the casting will be covered by the cavities 11 on the left and right sides, and the positioning rods 102 distributed on the left and right sides of the casting will clamp and position the casting.

[0057] In this arrangement, the cavity 11 itself has no specific size and shape, and the specific size and shape of the cavity 11 is determined by the size and shape of the casting itself. For example, a round casting will form a round cavity 11 after squeezing the positioning rods 102 on the mounting plate 101; a square casting will form a square cavity 11.

[0058] Even for irregular-shaped castings, if conventional positioning fixtures 2 are used, it is necessary to specially make fixtures 2 that match the castings, which is very troublesome. However, the above positioning method, when facing irregular-shaped castings, will form irregular-shaped cavities 11 that match the castings, and then when facing castings of different sizes and shapes, the positioning assembly 10 can quickly and efficiently position the castings, thereby significantly improving the efficiency of daily processing and production of different types of castings.

[0059] In this embodiment, the positioning rod 102 is made of a flexible material. When the casting is in contact with the positioning rod 102 , the positioning rod 102 will not cause damage to the surrounding side of the casting.

[0060] Specifically, the mounting plate 101 is composed of two rectangular parallelepiped plates, which are spaced apart in the horizontal direction, and the bottoms of the two plates are connected to the corresponding slide seats 5. A plurality of circular through holes are provided through the two plates, and these through holes are respectively distributed throughout the two plates. The positioning rod 102 is inserted between the corresponding through holes on the two plates in the horizontal direction. In this embodiment, the size of the positioning rod 102 is slightly larger than the size of the through hole on the plate, that is, the positioning rod 102 and the corresponding through hole are installed in a micro-interference manner, which enables the positioning rod 102 to slide on the mounting plate 101.

[0061] At the same time, one end of the positioning rod 102 is integrally formed with an end cap, and the size of the end cap is larger than the size of the through hole. Specifically, when installing the positioning rod 102, the end of the positioning rod 102 without the end cap is inserted into the through hole of one of the plates, and the end is extended from the other plate. The end of the positioning rod 102 with the end cap is stuck on the outside of the through hole on the plate.

[0062] Reference Figure 2 Fasteners 12 are inserted between the four corners of the two plates. After the fasteners 12 are inserted, a nut is screwed on one end of the fasteners 12 to fix the two plates.

[0063] Further, refer to Figure 2 A limiting plate 13 is provided on one side of the mounting plate 101 away from the positioning rod 102. The limiting plate 13 is in a rectangular parallelepiped shape, and the four corners of the limiting plate 13 are respectively sleeved on the four fasteners 12. A certain space is reserved between the limiting plate 13 and the mounting plate 101 for the positioning rod 102 to slide. During the sliding process of the positioning rod 102, the limiting plate 13 can effectively prevent the positioning rod 102 from sliding off the mounting plate 101, thereby playing a certain role in limiting the sliding of the positioning rod 102.

[0064] In this embodiment, the limit plate 13 is transparent. By setting the limit plate 13 to be transparent, the staff can observe the positioning effect of the casting through the limit plate 13, which helps the staff to grasp the positioning of the casting at any time and is more convenient to use.

[0065] Embodiment 3:

[0066] The difference between the embodiment of the present application and embodiment 2 is that:

[0067] The limit plate 13 is set to slide in the direction close to or away from the mounting plate 101. In this setting mode, the limit plate 13 is set to a sliding installation mode, and when the left and right ends of the casting are positioned. In this state, one of the limit plates 13 is slid in the direction close to the mounting plate 101, and the positioning rod 102 is squeezed by the limit plate 13, so that the casting inserted into the cavity 11 is translated toward the other side under the drive of the positioning rod 102. In this way, the position of the entire casting can be adjusted, making the casting more convenient during the welding process.

[0068] Specifically, refer to Figure 2 and Figure 4 The side wall of the fastener 12 is provided with a moving groove 14 along its length direction, and a moving block 15 adapted to the moving groove 14 is integrally formed at the connection between the limiting plate 13 and the fastener 12, and the moving block 15 is slidably installed in the moving groove 14. The sliding movement of the limiting plate 13 on the fastener 12 is achieved by using the moving groove 14 and the moving block 15.

[0069] As another embodiment, internal threaded holes are formed at the four corners of the limiting plate 13, and the fastener 12 is a screw, one end of the fastener 12 is fastened to the mounting plate 101 through a corresponding positioning seat, and the other end of the fastener 12 is sleeved in the internal threaded hole of the limiting plate 13. In this way, the sliding of the limiting plate 13 can be achieved by rotating the four fasteners 12 at the same time.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
