Description

Technical Field

[0001] This utility model relates to the field of straightening device technology, specifically a straightening device for a linear guide rail cage. Background Technology

[0002] The cage (also known as retainer or spacer) of a linear guide is a key component for guiding and spacing rolling elements. It is mainly used to ensure that rolling elements (such as balls and rollers) are evenly distributed within the guide, avoiding collisions or friction between them, thereby improving the motion accuracy, load-bearing capacity and service life of the guide.

[0003] The machining and straightening of the linear guide cage is a key process to ensure its accuracy and reliability. Especially in high-precision, high-speed or heavy-load applications, the straightness, parallelism and dimensional stability of the cage directly affect the motion performance of the guide.

[0004] Existing metal linear guide cage straightening typically involves using hydraulic or screw presses to squeeze and fine-tune deformed areas. During operation, after each fine-tuning, the cage must be manually inspected. After measuring other deformed areas, a second fine-tuning is performed, and this process is repeated until the desired straightness is achieved. This method requires frequent handling of the cage. To simplify this operation, a linear guide cage straightening device is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a linear guide rail cage straightening device in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a linear guide rail cage straightening device, comprising a hydraulic straightening machine consisting of a worktable, a hydraulic press, and a pressure block. The hydraulic press is distributed and installed in the middle of the rear end of the worktable and extends to the top of the worktable. The pressure block is fixed to the bottom of the output end of the hydraulic press. The top of the worktable is symmetrically provided with convex rail grooves. The worktable is connected to an adjustable support assembly through the convex rail grooves. The adjustable support assembly is used to provide support for the cage. A distance sensor is installed on the top of the worktable between the two sets of adjustable support assemblies. The distance sensor is used to detect the horizontal height of the lower surface of the cage placed on top of the two adjustable support assemblies, thereby determining whether the cage is in a flat state.

[0007] The adjustable support assembly includes a support unit and a clamping unit;

[0008] The support unit is used to provide support for the placement of the cage, and the clamping unit is used to clamp the cage, thereby facilitating the squeezing and fine-tuning operation of the cage side end.

[0009] As a further embodiment of this utility model: the support unit includes a convex slide, an L-shaped support base, a fixed side plate, and locking bolts;

[0010] The convex slide block is horizontally slidably connected to the inner side of the convex rail groove and extends to the upper surface of the worktable; the L-shaped support base is distributed on the top of the worktable and is fixedly connected to the top of the convex slide block.

[0011] The fixed side plate is fixed to one side of the outer wall of the L-shaped support base and fits against the upper surface of the worktable. The locking bolt passes through the fixed side plate from the top and fits tightly against the bottom of the inner wall of the convex rail groove. The locking bolt is threaded to the fixed side plate and is used to fix the position of the convex slide and the L-shaped support base.

[0012] Two sets of convex slides and L-shaped support seats are distributed on both sides of the pressure block. The L-shaped support seats are used to provide support for the placement of the cage.

[0013] As a further improvement of this utility model: the clamping unit includes an electric push rod and a clamping component;

[0014] The electric push rod is fixedly installed at the top of the rear end of the L-shaped support base. The clamping member is fixed at the top of the output end of the electric push rod and extends to the top of the front end of the L-shaped support base. The clamping member is driven to move down by the electric push rod to clamp the retainer placed on the upper surface of the front end of the L-shaped support base.

[0015] As a further improvement of this utility model: a photoelectric sensor is installed on the side of the L-shaped support away from the fixed side plate, and the photoelectric sensor is used to detect whether a retainer is placed on the top of the L-shaped support;

[0016] The top horizontal height of the photoelectric sensor is lower than the horizontal height of the upper surface of the front end of the L-shaped support.

[0017] As a further embodiment of this utility model: an electric push rod on one of the L-shaped support bases is electrically connected to a photoelectric sensor on another L-shaped support base via a controller; a display screen is installed on the top of the workbench near the front end of the hydraulic press; and the distance sensor is electrically connected to the display screen via a wire.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By setting up a distance sensor and an adjustable support assembly, the distance sensor detects the horizontal height of the lower surface of the cage. The operator can then manually move the cage to directly determine the location of the deformed part of the cage, which can effectively improve the straightening efficiency of the cage. At the same time, through the cooperation of photoelectric sensors and clamping units, stable straightening operation of the side end of the cage can be achieved, making the operation simple and convenient.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3 In this embodiment of the present invention, a linear guide rail cage straightening device includes a hydraulic straightening machine 1 consisting of a worktable 101, a hydraulic press 103, and a pressure block 104. The hydraulic press 103 is distributed and installed in the middle of the rear end of the worktable 101 and extends to the top of the worktable 101. The pressure block 104 is fixed to the bottom of the output end of the hydraulic press 103. The top of the worktable 101 is symmetrically provided with convex rail grooves 102. The worktable 101 is connected to an adjustable support assembly 2 through the convex rail grooves 102. The adjustable support assembly 2 is used to provide support for the cage. A distance sensor 3 is installed on the top of the worktable 101 between the two sets of adjustable support assemblies 2. The distance sensor 3 is used to detect the horizontal height of the lower surface of the cage placed on the top of the two adjustable support assemblies 2, thereby determining whether the cage is in a flat state.

[0026] The adjustable support assembly 2 includes a support unit and a clamping unit;

[0027] The support unit provides support for the placement of the cage, and the clamping unit is used to clamp the cage, thereby facilitating the squeezing and fine-tuning operation of the cage side end;

[0028] The support unit includes a convex slide 201, an L-shaped support 202, a fixed side plate 203, and a locking bolt 204;

[0029] The convex slide 201 is horizontally slidably connected to the inner side of the convex rail groove 102 and extends to the upper surface of the worktable 101. The L-shaped support 202 is distributed on the top of the worktable 101 and is fixedly connected to the top of the convex slide 201.

[0030] The fixed side plate 203 is fixed to one side of the outer wall of the L-shaped support 202 and fits against the upper surface of the workbench 101. The locking bolt 204 passes through the fixed side plate 203 from the top and fits tightly against the bottom of the inner wall of the convex rail groove 102. The locking bolt 204 is threadedly connected to the fixed side plate 203 to fix the position of the convex slide 201 and the L-shaped support 202.

[0031] Two sets of convex slides 201 and L-shaped support seats 202 are distributed on both sides of the pressure block 104. The L-shaped support seats 202 are used to provide support for the placement of the cage.

[0032] A display screen 5 is installed on the top of the workbench 101 near the front end of the hydraulic press 103, and the distance sensor 3 is electrically connected to the display screen 5 via a wire.

[0033] In this embodiment, the straightening device is operated as follows:

[0034] The cage to be straightened is placed on the upper front surface of the two L-shaped support bases 202, with the cage passing through the area above the distance sensor 3 (it should be noted that the distance sensor 3 and the pressure block 104 are vertically aligned). The distance sensor 3 detects the horizontal height of the lower surface of the cage, and the detected data is transmitted to the display screen 5 for the operator to view and judge. By manually moving the cage, the operator can intuitively determine the location of the deformed part of the cage. When a deformed part occurs, the hydraulic press 103 can be started. When the hydraulic press 103 is running, the pressure block 104 moves down to squeeze and fine-tune the deformed part of the cage. After the pressure block 104 is reset, the cage is moved and detected again. This process is repeated to complete the straightening operation of the cage.

[0035] Please refer to this carefully. Figures 1-3 The clamping unit includes an electric push rod 205 and a clamping member 206;

[0036] The electric push rod 205 is fixedly installed on the top of the rear end of the L-shaped support 202. The clamping member 206 is fixed on the top of the output end of the electric push rod 205 and extends to the top of the front end of the L-shaped support 202. The clamping member 206 is driven to move down by the electric push rod 205 to clamp the retainer placed on the upper surface of the front end of the L-shaped support 202.

[0037] A photoelectric sensor 4 is installed on the side of the L-shaped support 202 away from the fixed side plate 203. The photoelectric sensor 4 is used to detect whether a retainer is placed on the top of the L-shaped support 202.

[0038] The top horizontal height of photoelectric sensor 4 is lower than the horizontal height of the upper surface of the front end of L-shaped support 202;

[0039] An electric push rod 205 on one L-shaped support 202 is electrically connected to a photoelectric sensor 4 on another L-shaped support 202 via a controller.

[0040] In this embodiment: Under normal conditions, the electric push rod 205 is in an extended state, that is, the clamping member 206 is away from the L-shaped support 202, which will not affect the removal, placement and horizontal movement of the cage.

[0041] If the cage has uneven side ends, the cage can only be supported by an L-shaped support 202. The uneven side ends should be close to the bottom of the pressure block 104 so that the pressure block 104 can squeeze and adjust the uneven side ends.

[0042] When one end of the retainer separates from an L-shaped support 202, the photoelectric sensor 4 on the L-shaped support 202 detects that no retainer is placed on the L-shaped support 202 and sends a signal to the controller. When the hydraulic press 103 is started, the controller first sends a signal to start the electric push rod 205 on another L-shaped support 202. The electric push rod 205 drives the clamping member 206 to move down and clamp the retainer to the other L-shaped support 202. After that, the hydraulic press 103 runs to make the pressure block 104 move down to squeeze and straighten the side end of the retainer. The clamping member 206 can keep the retainer in a stable state.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
