Description

Technical Field

[0001] This utility model belongs to the technical field of bone sawing equipment, specifically relating to a side-pressure adaptive anti-tilting structure for a bone sawing machine. Background Technology

[0002] Currently, bone sawing equipment is used to slice aggregates. Existing bone sawing equipment requires pressing (upward pressing) the aggregates when they are placed in the cutting area, and then a side-pushing mechanism is needed to push the aggregates sideways to slice them. The existing side-pushing mechanism only has the function of pushing the material, and the aggregates may be lifted up when they are being cut. In order to solve this problem, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a side-pressure adaptive anti-warping structure for a bone saw, which can prevent warping during the bone cutting process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a side-pressure adaptive anti-tilting structure for a bone saw, including multiple elastic side-pressure strips, wherein the side of the elastic side-pressure strips is formed with teeth, the elastic side-pressure strips can be moved toward the target object by a drive mechanism, and the elastic side-pressure strips press the side of the target object by deformation.

[0005] Furthermore, there are multiple locking teeth, which face outwards and are tilted downwards.

[0006] Furthermore, the elastic side pressure strip includes a deformation extension and a retaining tooth portion, the deformation extension being connected above the retaining tooth portion, and the thickness of the deformation extension being less than the thickness of the retaining tooth portion.

[0007] Furthermore, the locking tooth part includes a plate body and multiple locking teeth. The multiple locking teeth are connected to the upper side of the plate body, and a stop block is also provided below the multiple locking teeth. The side of the stop block is flush with the side of the locking teeth.

[0008] Furthermore, the driving mechanism includes a driving cylinder, the output end of which is connected to a connecting block, the connecting block having multiple mounting holes, and the multiple deformable extensions extending into the multiple mounting holes for connection.

[0009] Furthermore, the connecting block includes a connecting rear shell and a front cover plate. The connecting rear shell forms multiple clearance channels, which are adapted to the elastic extension portion. The front cover plate and the connecting rear shell are detachably connected. After the front cover plate and the connecting rear shell are connected, the clearance channels and the surface of the front cover plate surround each other to form mounting holes.

[0010] Furthermore, multiple sets of connecting holes are formed on the front cover plate, and the multiple sets of connecting holes are spaced apart. Each set of connecting holes corresponds to its corresponding clearance channel. A through hole is formed on the elastic extension. The connector passes through the connecting hole and the through hole to fix the elastic extension.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the elastic side pressure strip is equipped with locking teeth. During the feeding process, the locking teeth will penetrate or abut against the surface of the aggregate to achieve a fixing effect and prevent the aggregate from warping. Moreover, in this solution, the elastic side pressure strip is made of deformable material, and the output stroke of the drive mechanism is constant. However, the side of the aggregate is an irregular surface. Some elastic side pressure strips first abut against the surface of the aggregate and deform. Due to the restoring force generated by the deformation of the elastic side pressure strip itself, the locking teeth on the elastic side pressure strip will tightly abut against the surface of the aggregate. The elastic side pressure strips that come into contact with the surface of the aggregate later have a smaller restoring force after deformation, but they can still tightly abut against the surface of the aggregate. This design ensures compression and prevents warping, and is also applicable to aggregates of various specifications. Attached Figure Description

[0014] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0015] like Figures 1-4 As shown, this embodiment provides a side-pressure adaptive anti-tilting structure for a bone saw, including 14 elastic side-pressure strips 1 and a drive mechanism 2.

[0016] The elastic side pressure strip 1 presses the side of the target object by deformation. The elastic side pressure strip 1 includes a deformation extension 11 and a toothed part 12. The deformation extension 11 is connected above the toothed part 12, and the thickness of the deformation extension 11 is less than the thickness of the toothed part 12. The toothed part 12 includes a plate and multiple teeth 121. The multiple teeth 121 are connected above the side of the plate. A stop block 122 is also provided below the multiple teeth 121. The stop block 122 is connected to the plate. The side of the stop block 122 is flush with the side of the teeth 121. The setting of the stop block 122 makes the pushing process more stable. There are multiple teeth 121. The teeth 121 face outward and downward. The inclined setting of the teeth 121 can better prevent the aggregate from tilting upward.

[0017] The drive mechanism 2 includes a drive cylinder body 21, which can be a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder. A connecting block 22 is connected to the output end of the drive cylinder body 21. The connecting block 22 has 14 mounting holes, and 14 deformable extensions 11 extend into these mounting holes for connection. Specifically, the connecting block 22 includes a connecting rear shell 221 and a front cover plate 222. The connecting rear shell 221 has multiple clearance channels that are adapted to fit the elastic extensions. The front cover plate 222 and the connecting rear shell 221 are detachably connected. Next, after the front cover plate 222 is connected to the rear shell 221, the clearance channel and the surface of the front cover plate 222 surround to form a mounting hole. The front cover plate 222 has 14 sets of connection holes 2221, which are spaced apart. Each set of connection holes 2221 has two holes, which are spaced vertically apart. Each set of connection holes 2221 corresponds to its corresponding clearance channel. The elastic extension has a through hole. The connector passes through the connection hole 2221 and the through hole to fix the elastic extension. The connector can be a screw.

[0018] In this scheme, the drive mechanism 2 can also adopt other telescopic structures, not limited to the cylinder body.

[0019] Working principle: The side-pressure adaptive anti-tilting structure of this solution requires movement before the upper pressure aggregate structure moves. This is achieved by the drive cylinder 21 pushing out, and the connecting block 22 driving multiple elastic side-pressure strips 1 to push forward towards the aggregate. The pushing stroke of the drive cylinder 21 is a set value, which can be adjusted according to actual conditions. After the elastic side-pressure strips 1 are pushed out, they push the aggregate forward one notch, and the locking teeth 121 will penetrate or abut against the surface of the aggregate to achieve a fixing effect, preventing the aggregate from tilting during cutting. Because the side of the aggregate is irregular, some elastic side-pressure strips 1... When the elastic side pressure strip 1 is pressed against the aggregate surface, the deformation extension 11 deforms, and the restoring force generated by the deformation of the elastic side pressure strip 1 itself will drive the teeth 121 on the teeth 12 on the elastic side pressure strip 1 to press tightly against the aggregate surface. The teeth 121 on the teeth 12 on the elastic side pressure strip 1 that then contact the aggregate surface have a relatively small restoring force generated by the deformation extension 11 on the elastic side pressure strip 1 itself, but they can still press tightly against the aggregate surface. This setting ensures compression and anti-warping while being applicable to aggregates of various specifications.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
