Technical Field

[0001] The utility model relates to a workbench, in particular to a novel workbench for pump processing, belonging to the technical field of pump body processing. Background Art

[0002] The pump body needs to rotate during machining.

Similarly, the applicant has designed a new worktable for pump machining and filed the following application. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a new workbench for pump processing.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new workbench for pump processing, comprising a base, a turntable suspended on the base, a limiting cylinder locked on the top surface of the turntable, a plurality of rotatable claws arranged at equal intervals, and a top seat sleeved on the limiting cylinder to form a column inserted into the arc groove of the claws; when the top seat rotates relative to the limiting cylinder, the claws can be synchronously retracted toward the center to clamp and fix the pump body, and the base drives the pump body to rotate with the help of the turntable.

[0005] Preferably, the rotating shaft of the base has a pad, and the turntable is mounted above the pad so that a gap is formed between itself and the base to prevent friction. The gear set driven by the motor provided on the base can drive the rotating shaft and the turntable to rotate.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1-4 As shown: A new workbench for pump processing includes a base 1, a rotatable turntable 2 of the base 1 is locked with a limiting cylinder 3 at the top surface position by a fastener, and five clamping jaws 4 arranged at equal intervals on the limiting cylinder 3 can be synchronously retracted toward the center to clamp and fix the pump body placed in the limiting cylinder 3.

[0021] Furthermore, the above-mentioned base 1 has a cavity, in which a motor 101 is fixed. The rotating shaft 102 located at the center of the base 1 and the motor 101 are transmitted through a gear set 103 composed of several gears. A pad 104 is installed on the rotating shaft 102, and the turntable 2 driven by the rotating shaft 102 is mounted above the pad 104. Therefore, the turntable 2 will be suspended on the top of the base 1. The gap formed by the turntable 2 and the base 1 can avoid friction between the two, so that the rotation of the turntable 2 is smoother.

[0022] Specifically, the above-mentioned rotating shaft 102 can also be replaced by a bolt member similar to a shoulder bolt. The characteristic of the shoulder bolt is that it has both a threaded section and a smooth section. By using this type of bolt member, it can be combined and fixed with the gear through the threaded section, and can also achieve its own normal rotation movement with the help of the smooth section; when the bolt member is screwed in, its head can press the turntable 2, so that the turntable 2 and the pad 104 are more stably combined into one, thereby improving the overall load-bearing capacity.

[0023] Furthermore, each of the above-mentioned jaws 4 is designed to be arc-shaped and has an arc groove 401 formed therein. Each jaw 4 is rotated and inserted into the socket 301 formed on the top outer edge of the limiting cylinder 3 through its own plug column 402. The top seat 5 rotatably sleeved on the top of the limiting cylinder 3 has a column 511 that can pass through the arc groove 401 of the jaw 4. When the top seat 5 rotates relative to the limiting cylinder 3, the column 511 can be used to drive each of the above-mentioned jaws 4 to retract toward the center synchronously.

[0024] Specifically, the top seat 5 is formed by the upper seat 501 and the lower seat 502 engaging with each other. The upper seat 501 has a column 511 formed on its inner side for cooperating with the clamping jaw 4, while the lower seat 502 has a rib 512 formed on its inner side. When the upper seat 501 and the lower seat 502 are assembled, the inner cavity formed by the two allows the clamping jaw 4 to be retracted when rotating and expanding, so as to prevent the subsequent placement of other pump bodies from being blocked. At this time, the rib 512 can support the retracted clamping jaw 4. Of course, since the top seat 5 is sleeved on the top of the limiting cylinder 3, in order to prevent the two from separating from each other, the limiting cylinder 3 is also formed with an outwardly protruding stop ridge 302. The stop ridge 302 can prevent the top seat 5 from separating by cooperating with the lower seat 502.

[0025] Specifically, when the top seat 5 and the limiting cylinder 3 are sleeved and combined, some anti-slip structures similar to anti-slip grooves can be provided at the position where the two contact each other to prevent the clamping jaws 4 from loosening due to their free movement.

[0026] Furthermore, an annular guide groove 303 is formed on the outer edge of the above-mentioned limit cylinder 3, and the sockets 301 for inserting the plug posts 402 of each clamping jaw 4 are evenly spaced on the guide groove 303. The column 511 of the top seat 5 will extend into the guide groove 303 after passing through the arc groove 401 of the clamping jaw 4; when the top seat 5 rotates relative to the limit cylinder 3, the column 511 can move along the guide groove 303, thereby driving the clamping jaw 4 to retract or expand.

[0027] As mentioned in the background technology, the pump body machining rotary table in "CN220782941U" uses a clamping assembly with bolts to clamp and secure the pump body on the table. Repeated screwing in and out of the bolts can easily cause thread wear, leading to loosening of the pump body. In contrast, this design uses a number of linked, retractable jaws to secure the pump body. Because there are no threads, repeated use does not affect the clamping tightness of the pump body. Furthermore, the linked retraction of the jaws allows this design to be used to secure pump bodies of varying specifications, resulting in greater applicability overall.

[0028] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
