Abstract
The utility model discloses an anti-creep sliding table cylinder, which comprises a cylinder body, wherein a guide rail and a sliding table are fixed on the upper end surface of the cylinder body, racks are respectively arranged on one sides of the guide rail and the sliding table, a retainer is arranged between the guide rail and the sliding table, a roller is arranged in the retainer, the roller is arranged in an inclined manner, and one end of the upper part of the roller and the other end of the lower part of the roller are respectively meshed with the racks arranged on the guide rail and the sliding table; the middle part of the retainer is provided with a gear assembly, the gear assembly comprises a gear carrier and a gear, the gear carrier is fixed on the retainer, the gear is arranged on the gear carrier, and the gear is respectively meshed with racks arranged on the guide rail and the sliding table. Compared with the prior art, the utility model the advantage be: the utility model adds a rack and pinion structure between the retainer and the guide rail, which ensures that the retainers on both sides will not creep and shift back and forth due to the accumulation of the movement times during the operation; the service life is greatly prolonged, and the use risk is reduced.
Description
Technical Field
The utility model relates to a, especially, relate to a prevent wriggling slip table cylinder.
Background
The conventional sliding table cylinder consists of a sliding table and a double-rod cylinder, and the original sliding table structure consists of a guide rail, a roller and a retainer; the double-rod part is mainly used for exerting force, and the sliding table is mainly used for bearing load and ensuring high precision. However, in operation, the motion times of the holders on the two sides are accumulated, so that the holders on the two sides creep and are staggered front and back. Therefore, the development of an anti-creep sliding table cylinder becomes a problem to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned not enough, provide a prevent wriggling slip table cylinder.
The above object of the present invention is achieved by the following technical solutions: a guide rail and a sliding table are fixed on the upper end face of the cylinder body, racks are mounted on one side of the guide rail opposite to the sliding table, a retainer is arranged between the guide rail and the sliding table, a roller is mounted in the retainer and is mounted in an inclined mode, and one end of the upper portion of the roller is meshed with the rack mounted on the guide rail; the middle part of the retainer is provided with a gear assembly, the gear assembly comprises a gear carrier and a gear, the gear carrier is fixed on the retainer, the gear is arranged on the gear carrier, and the gear is respectively meshed with racks arranged on the guide rail and the sliding table.
The utility model discloses a theory of operation:
when the cylinder extends out, the end plate drives the sliding table to extend out, the rollers on the two sides roll forwards, friction is reduced, guiding precision is guaranteed, synchronous movement of the retainers is achieved due to the gear and rack structures on the two sides, and the retainers on the two sides are prevented from being damaged due to the fact that the retainers on the left side and the right side are staggered forwards and backwards due to creeping;
when the cylinder retracts, the end plate drives the sliding table to retract, the rollers on the two sides roll backwards, friction is reduced, guiding precision is guaranteed, synchronous movement of the retainers is achieved due to the gear and rack structures on the two sides, and the retainers on the two sides are guaranteed against damage to products due to the fact that the retainers on the left side and the right side are staggered forwards and backwards due to creeping.
Compared with the prior art, the utility model the advantage be: the utility model adds a rack and pinion structure between the retainer and the guide rail, which ensures that the retainers on both sides will not creep and shift back and forth due to the accumulation of the movement times during the operation; the service life is greatly prolonged, and the use risk is reduced.

Fig. 2 is a schematic top view of the present invention.
Fig. 3 is a schematic view of the assembly between the gear, rack, holder, roller and guide rail according to the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, an anti-creep sliding table cylinder comprises a cylinder body 1, wherein a guide rail 2 (a rack is convenient to show and a profile of the guide rail is omitted in the drawing) and a sliding table 3 (a rack is convenient to show and a profile of the sliding table on one side is omitted in the drawing) are fixed on the upper end face of the cylinder body 1, racks 4 are respectively installed on one side of the guide rail 2 and the sliding table 3 on the opposite side, a retainer 5 is arranged between the guide rail 2 and the sliding table 3, a roller 6 is installed in the retainer 5, the roller 6 is installed in an inclined manner, and one end of the upper part of the roller 6 and the other end of the lower part of; the middle of the retainer 5 is provided with a gear assembly 7, the gear assembly 7 comprises a gear carrier 7-1 and a gear 7-2, the gear carrier 7-1 is fixed on the retainer 5, the gear 7-2 is installed on the gear carrier 7-1, and the gear 7-2 is respectively meshed with the rack 4 installed on the guide rail 2 and the sliding table 3.
The utility model discloses a theory of operation:
when the cylinder extends out, the end plate drives the sliding table 3 to extend out, the rollers 6 on the two sides roll forwards, friction is reduced, and guiding precision is guaranteed, synchronous movement of the retainers is realized due to the structures of the gears 7-2 and the racks 4 on the two sides, and the retainers 5 on the two sides are guaranteed against damage to products due to the fact that the retainers 5 on the left side and the right side are staggered forwards and backwards due to creeping;
when the cylinder retracts, the end plate drives the sliding table 3 to retract, the rollers 6 on the two sides roll backwards to reduce friction and ensure guiding precision, the gear 7-2 and the rack 4 on the two sides realize synchronous movement of the retainer 5, and the retainer 5 on the two sides can be prevented from being damaged due to the fact that the retainer 5 on the left side and the retainer 5 on the right side are staggered forwards and backwards due to wriggling.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
