Description

Technical Field

[0001] This utility model relates to the field of clamping and limiting blocks, specifically a clamping and limiting block with a positioning and installation structure. Background Technology

[0002] In machining, welding, or assembly processes, clamping and limiting blocks are commonly used functional components, primarily for fixing, limiting, or clamping workpieces to ensure machining accuracy and stability. Existing clamping and limiting blocks are typically fixed to fixtures or mounting bases using bolts.

[0003] However, when fixing the bolts, the operator needs to place the clamping limit block on the mounting base and manually adjust its position to align the mounting hole on the limit block with the threaded hole on the mounting base. After alignment, the bolts are then tightened. Since the mounting holes are usually through holes or countersunk holes, if the operator accidentally touches or shifts the position while adjusting, the hole may become misaligned, requiring readjustment and affecting installation efficiency. Before the bolts are fully tightened, the clamping limit block may shift due to vibration or external force, resulting in a decrease in installation accuracy. For batch installation scenarios, repeated alignment adjustments will increase operation time and reduce production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping and limiting block with a positioning and installation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping and limiting block with a positioning and mounting structure, comprising a clamping and limiting block body, a mounting base provided below the clamping and limiting block body, a threaded hole provided on the outer surface of the mounting base, and positioning components and stabilizing components provided on the surface and inside of the clamping and limiting block body and the mounting base.

[0006] The positioning component includes:

[0007] The mounting slot is used to position the fixed column.

[0008] The limiting groove is used to cooperate with the rack for limiting movement;

[0009] Cavity 1 is used to stabilize its internal mechanism;

[0010] Movable parts are used to facilitate the release of the limit switch.

[0011] Preferably, the mounting groove is located at the top of the mounting base, and a limiting groove is formed on the inner wall of the mounting groove. A fixing post is fixed to the bottom of the pressing and limiting block body. A cavity is formed inside the fixing post. A gear is rotatably connected to the top of the inner wall of the cavity, and a gear is rotatably connected to the top of the inner wall of the cavity. A rack is slidably connected to the bottom of the inner wall of the cavity. The end of the rack away from the gear is inserted through the fixing post. The rack meshes with the gear and the gear is meshed with the gear. A short rod is fixed to the bottom of the inner wall of the cavity. A spring is fixed to the outer surface of the short rod. The end of the spring away from the short rod is fixed to the end of the rack near the gear. The fixing post is installed into the mounting groove for positioning. Through the spring, gear 2, and gear 1, each rack moves radially synchronously into the limiting groove, thus limiting the pressing and limiting block body and the mounting base to each other and preventing accidental contact and displacement.

[0012] Preferably, the movable component includes a second cavity, which is located inside the clamping and limiting block body. A rotating rod is fixed to the top of the gear one, and the top of the rotating rod passes through the second cavity, with the rotating rod rotatably connected to the inner wall of the second cavity. A sliding rod is provided on the surface of the clamping and limiting block body, with the bottom of the sliding rod passing through the clamping and limiting block body. A groove is formed at the top of the rotating rod, and the bottom of the sliding rod extends into the groove. An arc-shaped groove is formed on the inner wall of the groove. An abutment rod is fixed to the outer surface of the sliding rod, and the surface of the abutment rod abuts against the inner wall of the arc-shaped groove. A fixing block is fixed to the sliding rod. When the bolts are removed and the sliding rod is pressed, the surface of the abutment rod abuts against the inner wall of the arc-shaped groove, causing the rotating rod and gear one to rotate synchronously, which in turn drives gear two to rotate. At this time, the rack disengages from the limiting groove, thereby releasing the clamping and limiting block body from the mounting base, facilitating disassembly and maintenance.

[0013] Preferably, the stabilizing component includes a stabilizing groove formed on the outer surface of the fixed block. A connecting groove is formed on the top of the pressing and limiting block body. A short column is rotatably connected to the inner wall of the connecting groove. A baffle is fixed through and fixed to the top of the short column. A rubber strip one is fixed to the outer surface of the short column. A rubber strip two is fixed to the inner wall of the connecting groove. Rotating the baffle into the stabilizing groove limits the fixed block and the sliding rod, preventing accidental contact that could affect stability. The rubber strip one and rubber strip two prevent the short column from rotating.

[0014] Preferably, the end of the rack away from the spring is set as an inclined surface, which allows the rack to move when it is abutted without affecting the docking.

[0015] Preferably, there are four sets of rubber strips, and all four sets of rubber strips are arranged in a circular array with the center of the short column as the axis. There are eight rubber strips, and the eight rubber strips are divided into two groups and arranged in a circular array on the inner wall of the connecting groove, which facilitates the limiting of the short column and prevents it from rotating.

[0016] Compared with the prior art, the present invention provides a clamping and limiting block with a positioning and installation structure, which has the following advantages:

[0017] 1. This clamping and limiting block with a positioning and installation structure, through the set positioning components, allows the fixing post to be installed into the installation groove for positioning when installation is required. Through the spring, gear two, and gear one, each rack moves radially synchronously into the limiting groove, thus limiting the clamping and limiting block body and the mounting base to each other and preventing accidental contact that could cause displacement. At this time, it can be fixed and installed normally with bolts. When it is necessary to remove and maintain, the bolts are removed, the sliding rod is pressed, and through the abutment rod and the arc groove, the rotating rod, gear one, and gear two rotate, causing the rack to disengage from the limiting groove, thus releasing the clamping and limiting block body from the mounting base, facilitating removal and maintenance.

[0018] 2. The clamping and limiting block with positioning and installation structure, through the set stabilizing components, when the clamping and limiting block body and the mounting base are installed, the baffle is rotated so that the baffle moves into the stabilizing groove, which can limit the fixed block and the sliding rod, and avoid accidental contact that affects stability. The set rubber strip one and rubber strip two prevent the short column from rotating. Attached Figure Description

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a clamping and limiting block with a positioning and installation structure, including a clamping and limiting block body 1, a mounting base 2 is provided below the clamping and limiting block body 1, a threaded hole 3 is provided on the outer surface of the mounting base 2, and positioning components 4 and stabilizing components 5 are provided on the surface and inside of the clamping and limiting block body 1 and the mounting base 2; the positioning component 4 includes: a mounting groove 40, a limiting groove 41, a fixing post 42, a cavity 1 43, a gear 1 44, a gear 2 45, a rack 46, a short rod 47, a spring 48, a movable part 49, a cavity 2 490, a rotating rod 491, a sliding rod 492, a groove 493, an arc groove 494, a contact rod 495, and a fixing block 496.

[0026] The mounting groove 40 is located at the top of the mounting base 2. A limiting groove 41 is formed on the inner wall of the mounting groove 40. A fixing post 42 is fixed to the bottom of the pressing and limiting block body 1. A cavity 43 is formed inside the fixing post 42. A gear 44 is rotatably connected to the top of the inner wall of the cavity 43. A gear 45 is rotatably connected to the top of the inner wall of the cavity 43. A rack 46 is slidably connected to the bottom of the inner wall of the cavity 43. The end of the rack 46 away from the gear 44 passes through the fixing post 42. The rack 46 meshes with the gear 45, and the gears 44 and 45 mesh. A short rod 47 is fixed to the bottom of the inner wall of the cavity 43. A spring 48 is fixed to the outer surface of the rod 47. The end of the spring 48 away from the short rod 47 is fixed to the end of the rack 46 near the gear 44. The movable part 49 includes a cavity 490, which is opened inside the pressing and limiting block body 1. A rotating rod 491 is fixed to the top of the gear 44. The top of the rotating rod 491 passes through the cavity 490 and is rotatably connected to the inner wall of the cavity 490. A sliding rod 492 is provided on the surface of the pressing and limiting block body 1. The bottom of the sliding rod 492 passes through the pressing and limiting block body 1. A groove 493 is opened at the top of the rotating rod 491 and the bottom of the sliding rod 492 extends into the cavity. Inside the groove 493, an arc-shaped groove 494 is formed on the inner wall of the groove 493. An abutment rod 495 is fixed on the outer surface of the slide rod 492. The surface of the abutment rod 495 abuts against the inner wall of the arc-shaped groove 494. A fixing block 496 is fixed through and fixed to the slide rod 492. The end of the rack 46 away from the spring 48 is set as an inclined surface. The fixing post 42 is installed into the mounting groove 40 for positioning. At the same time, the inclined surface of the rack 46 abuts against the inner wall of the mounting groove 40. The rack 46 moves into the cavity 43, the spring 48 is compressed, and the rack 46 synchronously drives the gear 45 and the gear 44 to rotate, so that each rack 46 moves radially synchronously. When the rack 46 is parallel to the limiting groove 41, the spring 48 is released, and the rack 46 enters the limiting groove 41, which can limit the clamping limiting block body 1 and the mounting base 2 to each other, preventing accidental contact and displacement. When disassembly and maintenance are required, the bolts are removed, the sliding rod 492 is pressed, and the abutment rod 495 moves synchronously. At this time, the surface of the abutment rod 495 abuts against the inner wall of the arc groove 494, thereby driving the rotating rod 491 and the first gear 44 to rotate synchronously, which can drive the second gear 45 to rotate. At this time, the rack 46 disengages from the limiting groove 41, thereby releasing the clamping limiting block body 1 and the mounting base 2 from the limiting position, making it convenient for disassembly and maintenance.

[0027] The stabilizing component 5 includes a stabilizing groove 50, which is formed on the outer surface of the fixed block 496. A connecting groove 51 is formed on the top of the pressing and limiting block body 1. A short column 52 is rotatably connected to the inner wall of the connecting groove 51. A baffle 53 is fixed through and fixed to the top of the short column 52. A rubber strip 1 54 is fixed to the outer surface of the short column 52. A rubber strip 2 55 is fixed to the inner wall of the connecting groove 51. There are four sets of rubber strip 1 54, and all four sets of rubber strip 1 54 are arranged in a circular array with the center of the short column 52 as the axis. There are eight rubber strip 2 55, and the eight rubber strip 2 55 are divided into two groups and arranged in a circular array on the inner wall of the connecting groove 51. By rotating the baffle 53, the baffle 53 moves into the stabilizing groove 50, which can limit the fixed block 496 and the sliding rod 492, and prevent accidental contact from affecting stability. The rubber strip 1 54 and rubber strip 2 55 prevent the short column 52 from rotating.

[0028] During installation, rotate the baffle 53 to disengage it from the stabilizing groove 50. Simultaneously, the baffle 53 drives the short column 52 to rotate. At this time, the surface of rubber strip 1 54 contacts the surface of rubber strip 2 55. The deformation of rubber strip 1 54 and rubber strip 2 55 does not affect the rotation of the short column 52. When the baffle 53 disengages from the stabilizing groove 50, rubber strip 1 54 is positioned between a set of rubber strips 2 55, thus stabilizing the short column 52. Then, install the fixing column 42 into the mounting groove 40 for positioning. Simultaneously, the inclined surface of the rack 46 contacts the inner wall of the mounting groove 40, and the rack 46 moves into the cavity 1 43. At the same time, the spring 48 is compressed, and the rack 46 synchronously drives the gear 2 45 and gear 1 44 to rotate, enabling each rack 46 to move radially synchronously, improving the consistency of movement. When the rack 46 is parallel to the limiting groove 41, the spring 48 is released, and the rack 46 enters the limiting groove 42. Within 1, the clamping limit block body 1 and the mounting base 2 are mutually limited, preventing accidental contact and displacement. At this time, the baffle 53 is rotated again, moving the baffle 53 into the stabilizing groove 50, which limits the fixing block 496 and the sliding rod 492, preventing accidental contact from affecting stability. At this time, the mounting holes between the clamping limit block body 1 and the mounting base 2 are aligned, and bolt fixing can be performed normally, improving installation efficiency. When disassembly and maintenance are required, the bolts are removed, and the baffle 53 is rotated to disengage from the stabilizing groove 50. At this time, the sliding rod 492 is pressed, and the abutment rod 495 moves synchronously. At this time, the surface of the abutment rod 495 abuts against the inner wall of the arc groove 494, thereby driving the rotating rod 491 and the first gear 44 to rotate synchronously, which in turn drives the second gear 45 to rotate. At this time, the rack 46 disengages from the limiting groove 41, thereby releasing the clamping limit block body 1 and the mounting base 2 from being limited, making it convenient for disassembly and maintenance.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
