Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and particularly relates to a fixture for mechanical manufacturing workpieces. Background Technique

[0002] In mechanical manufacturing, workpiece processing is a process of manufacturing final products from raw materials or semi-finished products through various processing methods. Workpiece processing usually involves a variety of different machining methods, and each method has its specific applications and advantages.

[0003] In the prior art solution, such as a fixture for mechanical manufacturing workpieces with application number 202420051838.2, it includes a base. Above one side of the base, a first support column is installed. Above the first support column, a first support plate is provided. A bolt penetrates through the inside of the first support plate. A rocker is connected to the outside of the bolt, and a first rotating plate is connected to the inside of the bolt.

[0004] In the above, through the side abutment of the support column, the clamping effect of the workpiece is balanced and stable, and the clamping requirements during workpiece manufacturing are basically achieved. However, only one end of the support column is rotationally matched with the rocker. When clamping the workpiece, one end of the workpiece will be squeezed and skewed by the support column, resulting in the situation that the workpiece constantly runs off during clamping. The center of the workpiece cannot be aligned with the center of the support column, and the actual clamping effect is not ideal. Therefore, it is necessary to improve this asymmetric clamping method. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fixture for mechanical manufacturing workpieces, aiming to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A fixture for mechanical manufacturing workpieces includes a placement mechanism. The placement mechanism includes a base and a receiving box. The bottom of the receiving box is fixedly connected to the base;

[0008] And, a pushing mechanism is provided beside the base. The pushing mechanism includes a U-shaped base fixedly connected to the side of the base. A cylinder is fixedly sleeved on the top of the U-shaped base. The output end of the cylinder is fixedly connected to a pushing block. One end of the pushing block is inserted with a toothed plate. The teeth of the toothed plate mesh with a gear. A key shaft is fixedly connected to the surface of the gear. A side rod is rotatably connected to the outer surface of the key shaft. The side rod is cooperated with a support mechanism.

[0009] As a preferred embodiment of the present utility model, the support mechanism includes a straight column fixedly connected to the upper surface of one end of the side rod. A transmission rod is rotatably connected to the outer surface of the straight column. A guiding portion is fixedly connected to the upper surface of the base, and the top of the guiding portion is hinged to the transmission rod.

[0010] As a preferred embodiment of the present utility model, the support mechanism further includes a stabilizing column and an abutting member. The outer surface of the stabilizing column is rotatably sleeved with the transmission rod. The abutting member includes a right-angle plate. One end of the right-angle plate is rotatably connected to the outer surface of the stabilizing column, and the other end of the right-angle plate is adaptively installed with an outer slideway.

[0011] As a preferred embodiment of the present utility model, a sliding column is slidably connected to the inner cavity of the outer slideway, and a contact hand is rotatably sleeved on the outer surface of the sliding column.

[0012] As a preferred embodiment of the present utility model, the toothed plate is a double-sided plate formed integrally, and two gears are provided. The two gears are symmetrically arranged on the side surface of the toothed plate.

[0013] As a preferred embodiment of the present utility model, a counterweight ring is fixedly sleeved on the outer surface of the pushing block, and the toothed plate is slidably connected to the base through a direction block.

[0014] As a preferred embodiment of the present utility model, the key shaft is fixedly connected to the base through a bearing seat at the bottom, and the center of the key shaft coincides with the center of the gear.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) Through the fixed connection between the air cylinder and the pushing block, it further helps the toothed plate to displace stably, so as to complete meshing with the gear, and clamp the workpiece side surface evenly. The rotational connection between the key shaft and the side rod enables the side rod to rotate, and the workpiece can be clamped at any angle and in any direction. At the same time, the workpiece is moved closer and adjusted in position by the side rod, helping the side surface of the workpiece to be stressed evenly, significantly reducing the skew of the workpiece when it is contacted and clamped, and also meeting the clamping requirements of different types of workpieces.

[0016] (2) By setting the contact hand, the contact hand can extend the time of approaching the workpiece, greatly reducing the skew of the workpiece, and also making the center of the workpiece coincide with the center of the contact hand as much as possible, achieving the effect of centering clamping.

Detailed implementation manners

[0024] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model in conjunction with the attached drawings of the specification.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments.

[0027] Embodiment 1

[0028] Referring to Figure 1-2 , which is the first embodiment of the present utility model. This embodiment provides a fixture for mechanical manufacturing workpieces, including a placement mechanism 100. The placement mechanism 100 includes a base 101 and a receiving box 102. The bottom of the receiving box 102 is fixedly connected to the base 101;

[0029] Moreover, a pushing mechanism 200 is arranged beside the base 101. The pushing mechanism 200 includes an L-shaped base 201 fixedly connected to the side surface of the base 101. A cylinder 202 is fixedly sleeved on the top of the L-shaped base 201. The output end of the cylinder 202 is fixedly connected to a pushing block 203. One end of the pushing block 203 is inserted with a toothed plate 205. The teeth of the toothed plate 205 mesh with a gear 206. The surface of the gear 206 is fixedly connected to a key shaft 207. The outer surface of the key shaft 207 is rotatably connected to a side rod 208. The side rod 208 is cooperatively provided with a support mechanism 300.

[0030] Specifically, the cooperation between the base 101 and the pushing mechanism 200 enables the workpiece to be firmly clamped and not shake due to external forces. The fixed connection between the cylinder 202 and the pushing block 203 further helps the toothed plate 205 to displace stably, so as to complete meshing with the gear 206 and clamp the side of the workpiece evenly. The rotational connection between the key shaft 207 and the side rod 208 enables the side rod 208 to rotate and move, and can clamp the workpiece at any angle and in any direction. At the same time, the workpiece is pushed close by the side rod 208 to adjust its position, helping the side of the workpiece to be stressed evenly, significantly reducing the situation of the workpiece skewing when being contacted and clamped, and also meeting the clamping requirements of different types of workpieces. The cooperation between the support mechanism 300 and the side rod 208 enables the side rod 208 to obtain support when rotating, further ensuring the stability of workpiece clamping.

[0031] Furthermore, the support mechanism 300 includes a straight column 301 fixedly connected to the upper surface of one end of the side rod 208. The outer surface of the straight column 301 is rotatably connected to a transmission rod 302. The upper surface of the base 101 is fixedly connected to a guiding part 303. The top of the guiding part 303 is hinged to the transmission rod 302.

[0032] Preferably, the rotation cooperation between the straight column 301, the transmission rod 302, and the side rod 208 enables the rotational movement to be transmitted twice, while also meeting the operating requirements of arbitrary clamping, saving unnecessary clamping steps. The hinged connection between the guiding portion 303 and the transmission rod 302 further supports the rotation of the transmission rod 302, preventing the transmission rod 302 from rotating and falling off, and significantly extending the effective duration of workpiece clamping.

[0033] It should be noted that the support mechanism 300 further includes a stabilizing column 304 and an abutting member 305. The outer surface of the stabilizing column 304 is rotatably sleeved with the transmission rod 302. The abutting member 305 includes a right-angled plate 305a. One end of the right-angled plate 305a is rotatably connected to the outer surface of the stabilizing column 304, and the other end of the right-angled plate 305a is fitted with an outer slideway 305b.

[0034] After that, the rotational sleeving of the stabilizing column 304 and the transmission rod 302 enables the rotational movement to be transmitted to the right-angled plate 305a again. The sliding cooperation between the outer slideway 305b and the sliding column 305c is better, and the clamping effect of the workpiece is better.

[0035] Embodiment 2

[0036] Refer to Figure 2-3 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides the relevant parts for realizing the effect of the contact hand 305d approaching and clamping.

[0037] Specifically, a sliding column 305c is slidably connected to the inner cavity of the outer slideway 305b, and a contact hand 305d is rotatably sleeved on the outer surface of the sliding column 305c.

[0038] Furthermore, the rotational sleeving of the sliding column 305c and the contact hand 305d enables the contact hand 305d to clamp the workpiece while sliding. Through a small rotational movement, the contact hand 305d can extend the approaching time with the workpiece, greatly reducing the situation of workpiece skew, and can also make the center of the workpiece coincide with the center of the contact hand 305d as much as possible, achieving the effect of centering clamping.

[0039] Preferably, the toothed plate 205 is a double-sided plate formed integrally, and two gears 206 are provided. The two gears 206 are symmetrically arranged on the side surface of the toothed plate 205.

[0040] Among them, the meshing of the toothed plate 205 and the gear 206 makes the meshing transmission more efficient, and the clamping effect on the side surface of the workpiece is more balanced.

[0041] Embodiment 3

[0042] Refer to Figure 2-5 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides the relevant parts for realizing the effect of stable transmission.

[0043] Specifically, a counterweight ring 204 is fixedly sleeved on the outer surface of the pushing block 203, and the toothed plate 205 is slidably connected to the base 101 through a direction block.

[0044] Furthermore, the fixed sleeving of the counterweight ring 204 on the pushing block 203 enables the pushing block 203 to maintain a stable self-weight during displacement. At the same time, the slidable connection between the toothed plate 205 and the base 101 further helps the sliding trajectory of the toothed plate 205 to remain straight, improving the displacement efficiency.

[0045] Preferably, the key shaft 207 is fixedly connected to the base 101 through a bearing seat at the bottom, and the center of the key shaft 207 coincides with the center of the gear 206.

[0046] Among them, the fixed connection between the key shaft 207 and the base 101 enables the key shaft 207 to obtain a stable support during rotation. At the same time, it is also beneficial to the transmission stability, indirectly enhancing the clamping and supporting effect on the side of the workpiece.

[0047] Working principle: First, take out the workpiece from the accommodation box 102 and place it on the base 101. Then start the cylinder 202. The cylinder 202 drives the pushing block 203 to stably displace the toothed plate 205. The teeth on the side of the toothed plate 205 are engaged with the gear 206. The key shaft 207 inserted at the center of the gear 206 can help the gear 206 rotate stably. Then the rotation of the gear 206 is transmitted to the straight column 301 through the side rod 208. The straight column 301 is transmitted to the stabilizing column 304 and the right-angle plate 305a through the transmission rod 302. After that, the outer slideway 305b is fixedly connected to the side of the right-angle plate 305a. The sliding column 305c is slidably connected to the outer slideway 305b. Finally, the contact hand 305d is rotatably sleeved on the sliding column 305c for centering clamping of the workpiece.
