Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a precision parts fixing tool. Background Art

[0002] Precision machining technology refers to various machining processes with machining accuracy and surface finish higher than the fine machining of corresponding machining methods. During precision machining, a fixture is required to fix the parts to be processed. However, the existing fixture can only fix the parts when working, and cannot adjust the angle of the parts when they are fixed. The adjustable range of machining points is small, the function is relatively single, and it cannot flexibly process parts of different sizes.

[0003] The existing patent CN216577749U fixed tooling, the adjustable fixing device for precision parts processing, controls the longitudinal transmission mechanism to move forward and backward, controls the horizontal transmission mechanism to move left and right, controls the vertical transmission mechanism to move up and down, controls the rotating mechanism to adjust the horizontal rotation, and then controls the clamping mechanism to clamp and fix the processed parts, so that the range of activities of the processed parts in the space is expanded, the range of selectable processing points is expanded, and it is convenient to process parts of various sizes to meet a variety of processing conditions;

[0004] The control rotation mechanism in the above-mentioned comparative document is relatively large in size, and the clamping and fixing device structure is relatively small. By comparing the above-mentioned clamping and fixing device, it can be seen that the clamped and fixed parts are relatively small in size. Therefore, clamping small parts by using a huge control rotation mechanism obviously has the negative effect of wasting the use of space, resulting in low practicality of the device. Therefore, the utility model proposes a precision parts fixing tool. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and to provide a precision parts fixing tool.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a precision parts fixing tool, comprising a fixing tool body, the fixing tool body comprising a bottom plate, the top two ends of the bottom plate are respectively provided with a first mounting plate and a second mounting plate, and the first mounting plate and the second mounting plate are slidably connected with a clamping assembly at one end close to each other;

[0007] The clamping assembly includes a clamping seat, and there are two clamping seats in total. A rubber pad is provided on the side where the two clamping seats are close to each other, and a rotating seat is provided on the end where the two clamping seats are away from each other. An adjusting rod is rotatably connected to the rotating seat and passes through the first mounting plate or the second mounting plate. A threaded groove is provided on the end of the adjusting rod away from the clamping seat. Sliding rods are provided on both sides of the rotating seat on the clamping seat, and the sliding rods slide through the first mounting plate or the second mounting plate. A spring is sleeved on the sliding rod, one end of the spring contacts the first mounting plate or the second mounting plate, and the other end of the spring is connected to the sliding rod.

[0008] As a preferred embodiment, a strip limit block is provided on the base plate at one end of the second mounting plate, auxiliary sliders are provided on both sides of the strip limit block on the base plate, the second mounting plate is slidably connected to the strip limit block and the auxiliary sliders, and the first mounting plate is connected to the base plate.

[0009] The beneficial effect of adopting the above further scheme is: the second mounting plate is limited by the strip limit block and the auxiliary slider to prevent the base plate from separating from the second mounting plate during use.

[0010] As a preferred embodiment, a sliding seat is slidably connected to the strip-shaped limit block, a support rod is provided on the top of the sliding seat, and the other end of the support rod is connected to the bottom of one of the clamping seats.

[0011] The beneficial effect of adopting the above further scheme is: the support rod is used to provide auxiliary support for the clamping seat to prevent the clamping seat from tilting on the strip limit block and the auxiliary sliding block. Further, under the action of the sliding seat, the clamping seat can be displaced together on the strip limit block through the sliding seat when sliding.

[0012] As a preferred implementation, mounting plates are provided on both sides of the bottom plate, and there are four mounting plates in total, and the four mounting plates are distributed in a rectangular shape.

[0013] The beneficial effect of adopting the above further solution is: the base plate is fixedly installed in a specified position by the mounting plate, so as to prevent the fixed tool body from tilting during use, thereby preventing the precision parts from being damaged.

[0014] As a preferred implementation, a limiting plate is provided on the second mounting plate above the strip-shaped limiting block, and a limiting bolt is threadedly connected to the limiting plate.

[0015] The beneficial effect of adopting the above further scheme is: through the setting of the limit bolt, after the second mounting plate slides to the specified position, it can be moved downward by rotating the limit bolt, so that the limit bolt squeezes the strip limit block to limit the second mounting plate, thereby preventing the second mounting plate from being displaced on the strip limit block and the auxiliary slider during use.

[0016] As a preferred implementation, the rubber pad is provided with fault-tolerant holes, and the fault-tolerant holes are distributed in a honeycomb shape.

[0017] The beneficial effect of adopting the above further scheme is: through the design of the fault-tolerant hole, when the clamping assembly clamps and fixes parts of different shapes, it can reserve deformation space for the parts after being squeezed under the action of the fault-tolerant hole, so that the rubber pad fits better with the outer wall of the part, thereby improving the practicability of the device in use.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, through the design of the sliding rod, the clamping assembly can directly place the part between the two rubber pads before clamping and fixing the part. At this time, the clamping seat drives the two clamping seats to approach each other under the action of the spring to clamp the part. There is no need to hold the part by hand and adjust the adjusting rods on both sides in turn. Further, by rotating the adjusting rod, the threaded groove is threadedly connected with the first mounting plate and the second mounting plate, so that the rubber pad squeezes and fixes the workpiece, preventing the part from being separated from the clamping assembly during use, making it more convenient to clamp the part.

[0020] 2. In the utility model, through the design of the fault-tolerant hole, when the clamping assembly clamps and fixes parts of different shapes, it can reserve deformation space for the parts after being squeezed under the action of the fault-tolerant hole, so that the rubber pad and the outer wall of the part are more closely fitted, and further under the action of the rubber pad, the outer wall of the precision part is protected. Since the rubber pad is made of rubber material, it can prevent the surface of the part from being damaged during squeezing and fixing under the action of rubber, thereby improving the practicability of the device in use.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1-4 As shown, the utility model provides a technical solution: a precision parts fixing tool, comprising a fixing tool body 1, the fixing tool body 1 comprises a bottom plate 2, the top two ends of the bottom plate 2 are respectively provided with a first mounting plate 3 and a second mounting plate 4, and the first mounting plate 3 and the second mounting plate 4 are slidably connected with a clamping assembly 6 at one end close to each other;

[0034] The clamping assembly 6 includes a clamping seat 61, and there are two clamping seats 61 in total. A rubber pad 62 is provided on the side where the two clamping seats 61 are close to each other, and a rotating seat 64 is provided on the end where the two clamping seats 61 are away from each other. An adjusting rod 65 that penetrates the first mounting plate 3 or the second mounting plate 4 is rotatably connected to the rotating seat 64. A threaded groove 651 is provided on the end of the adjusting rod 65 away from the clamping seat 61. Slide rods 63 are provided on both sides of the rotating seat 64 of the clamping seat 61. The slide rod 63 slides through the first mounting plate 3 or the second mounting plate 4. A spring 66 is sleeved on the slide rod 63. One end of the spring 66 contacts the first mounting plate 3 or the second mounting plate 4, and the other end of the spring 66 is connected to the slide rod 63. Mounting plates 23 are provided on both sides of the bottom plate 2. There are four mounting plates 23 in total, and the four mounting plates 23 are distributed in a rectangular shape. The rubber pad 62 is provided with a fault-tolerant hole 621, and the fault-tolerant hole 621 is distributed in a honeycomb shape. Through the design of the slide rod 63, the clamping assembly 6 can directly place the part between the two rubber pads 62 before clamping and fixing the part. At this time, the clamping seat 61 drives the two clamping seats 61 to approach each other under the action of the spring 66, and further rotates the adjusting rod 65 to make the threaded groove 651 threadedly connected with the first mounting plate 3 and the second mounting plate 4, so that the rubber pad 62 squeezes and fixes the workpiece, preventing the part from being separated from the clamping assembly 6 during use, making it more convenient to clamp the part, and solving the technical problem of manually supporting and adjusting the spacing between the clamping seats 61 when clamping the part.

[0035] Further, such as Figure 1 - Figure 2 As shown: a strip limit block 21 is provided on the bottom plate 2 at one end of the second mounting plate 4, and auxiliary sliders 22 are provided on both sides of the strip limit block 21 on the bottom plate 2. The second mounting plate 4 is slidably connected to the strip limit block 21 and the auxiliary slider 22. The first mounting plate 3 is connected to the bottom plate 2. The second mounting plate 4 is limited by the strip limit block 21 and the auxiliary slider 22 to prevent the bottom plate 2 and the second mounting plate 4 from being separated during use. Furthermore, the second mounting plate 4 can be displaced left and right on the bottom plate 2 by the strip limit block 21 and the auxiliary slider 22, thereby solving the technical problem of clamping and fixing parts of different sizes.

[0036] The above solution also has the problem that the second mounting plate 4 is prone to tilt during the displacement process. Figure 4As shown: In the present embodiment, a sliding seat 51 is slidably connected to the strip limit block 21, a support rod 5 is arranged on the top of the sliding seat 51, and the other end of the support rod 5 is connected to the bottom of one of the clamping seats 61, and the support rod 5 provides auxiliary support for the clamping seat 61 to prevent the clamping seat 61 from tilting on the strip limit block 21 and the auxiliary sliding block 22. Furthermore, under the action of the sliding seat 51, the clamping seat 61 can be displaced together on the strip limit block 21 through the sliding seat 51 when sliding.

[0037] The above solution still has the problem that the second mounting plate 4 is displaced on the strip limit block 21 and the auxiliary slide block 22 during the clamping process. Figure 2 As shown: In the present embodiment, a limiting plate 41 is arranged above the second mounting plate 4 and a limiting bolt 42 is threadedly connected to the limiting plate 41. By setting the limiting bolt 42, after the second mounting plate 4 slides to the specified position, the limiting bolt 42 can be rotated to move downward so that the limiting bolt 42 squeezes the strip limiting block 21 to limit the second mounting plate 4, thereby preventing the second mounting plate 4 from being displaced on the strip limiting block 21 and the auxiliary slider 22 during use.

[0038] Working principle:

[0039] like Figure 1-4 As shown, first, the fixed tool body 1 is installed in the specified position through the mounting plate 23, and the second mounting plate 4 is further slid and adjusted to a position suitable for the size of the part, and the limit bolt 42 is rotated downward to limit the second mounting plate 4 to prevent the second mounting plate 4 from shifting on the strip limit block 21 and the auxiliary slider 22 during use. After the adjustment is completed, the part is placed between the two rubber pads 62. At this time, the clamping seat 61, under the action of the spring 66, drives the two clamping seats 61 to approach each other to clamp the part. There is no need to hold the part by hand and adjust the adjusting rods 65 on both sides in turn. Further, by rotating the adjusting rod 65, the threaded groove 651 is threadedly connected to the first mounting plate 3 and the second mounting plate 4, so that the rubber pad 62 squeezes and fixes the workpiece, and under the action of the fault-tolerant hole 621, deformation space is reserved for the part after extrusion, so that the rubber pad 62 fits better with the outer wall of the part.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
