Technical Field
[0001] The present application relates to the technical field of machining auxiliary equipment, and in particular to a plane machining jig. Background Art
[0002] With the continuous development of social economy and the increasing level of science and technology, my country's manufacturing industry is also booming. As a commonly used tool in the manufacturing industry, fixtures are divided into tooling fixtures and testing fixtures. Among them, tooling fixtures are a kind of tooling fixtures designed to facilitate processing or meet precision requirements. They can clamp the parts to be processed and play an important role in the manufacturing industry.
[0003] Regarding the above-mentioned related technologies, when processing the surface of a smaller part, it is often necessary to clamp the end of the outer wall of the smaller part to expose the surface of the part to be processed, and the tooling and fixtures in the prior art are generally larger. Therefore, when in use, it is difficult to ensure the clamping effect of the end of the outer wall of the smaller part, which leads to a decrease in the subsequent processing effect of the smaller part, so it needs to be improved. Utility Model Content
[0004] In order to ensure the clamping effect on the outer wall ends of smaller parts, the present application provides a plane processing fixture.
[0005] The present application provides a plane processing jig, which adopts the following technical solution:
[0006] A plane processing jig comprises a mounting frame, on which a placing frame is further arranged, the placing frame is used for embedding parts to be processed, clamping mechanisms are arranged on opposite sides of the placing frame, each of the clamping mechanisms comprises a rotating frame, a clamping frame and a driving assembly, one end of the rotating frame is rotatably connected to the mounting frame, and the other end of the rotating frame is rotatably connected to the clamping frame, the driving assembly is used to drive the corresponding clamping frame to move away from one end of the placing frame, and to rotate the clamping frame and the corresponding rotating frame, and the bottom of each clamping frame close to one end of the placing frame is used to abut against the top of the part to be processed.
[0007] By adopting the above-mentioned technical scheme, compared with the prior art, since the tooling fixture is set larger, it is difficult to clamp the end of the outer wall of the smaller part. The present application enables the smaller part to be embedded on the top of the placement rack through the setting of the placement rack and the clamping mechanism, thereby realizing the positioning and auxiliary fixation of the smaller part. At the same time, the clamping rack is close to one end of the displacement rack, which can be driven by the driving assembly and the rotating rack to abut against the top of the part to be processed to realize the clamping and fixation of the smaller part, effectively reducing the probability of shaking or deviation of the smaller part when being clamped, and ensuring the clamping effect of the end of the outer wall of the smaller part.
[0008] Preferably, an abutment rod is provided on one end of each clamping rack close to the placement rack, the bottom end of the abutment rod is lower than the bottom end of the corresponding clamping rack, and the bottom end of the abutment rod is used to abut against the top end of the part to be processed.
[0009] By adopting the above technical solution, the abutment rod is set so that the bottom end of the abutment rod can abut against the top end of the part to be processed, thereby achieving fixation of the part to be processed with the cooperation of the placement rack. Since the area of the bottom end of the abutment rod is much smaller than the area of the bottom wall of the clamping rack, the abutment rod can abut against the end of the surface of the smaller part and be located outside the area to be processed on the smaller part, thereby ensuring the clamping effect on the end of the outer wall of the smaller part.
[0010] Preferably, a connecting frame is provided on the bottom end of the abutment rod, and an additional frame is provided on the bottom end of the connecting frame. The additional frame is slidably connected to the connecting frame, and the sliding direction of the additional frame is the axial direction of the abutment rod. An elastic member is also provided between the additional frame and the connecting frame, and the elastic member is used to continuously apply elastic force to the additional frame.
[0011] By adopting the above technical solution, the connection frame and the additional frame are arranged so that when one end of the clamping frame is driven by the driving assembly to approach the part to be processed, after the additional frame abuts against the surface of the part to be processed, the additional frame can slide relative to the connection frame, so that the elastic member is compressed, so that the elastic force applied by the elastic member to the additional frame becomes larger, thereby changing the abutment force of the additional frame on the part to be processed, changing the clamping effect of the part to be processed, thereby reducing the probability of the surface of the part to be processed being damaged due to excessive pressure applied by the additional frame on the part to be processed, and effectively protecting the part to be processed.
[0012] Preferably, a sliding portion is further provided on the top of the additional frame, and the sliding portion extends upward, passes through the corresponding connecting frame, and is slidably connected to the corresponding connecting frame.
[0013] By adopting the above technical solution, the sliding part is set so that the sliding part can guide the sliding of the additional frame. At the same time, the existence of the sliding part can also increase the stability of the additional frame during sliding and reduce the probability of excessive wear between the additional frame and the connecting frame.
[0014] Preferably, an elastic sleeve is further provided on the bottom end of the additional frame.
[0015] By adopting the above technical solution, the setting of the elastic sleeve can further reduce the degree of damage to the surface of the part to be processed by the bottom end of the additional frame, thereby reducing the probability of damage to the surface of the part to be processed due to excessive pressure applied by the additional frame to the part to be processed, and effectively protecting the part to be processed.
[0016] Preferably, the top end of the abutment rod is higher than the top end of the clamping frame, and the bottom end of the abutment rod extends downward, passes through the bottom end of the clamping frame, and is threadedly connected to the clamping frame.
[0017] By adopting the above-mentioned technical scheme, the threaded connection between the abutment rod and the clamping frame is set, so that relevant personnel can change the distance between the abutment rod and the bottom wall of the clamping frame by rotating the abutment rod, so that the abutment rod can abut against parts to be processed with different thicknesses, thereby increasing the scope of application and practicality of the present application. At the same time, relevant personnel can change the abutment effect of the bottom end of the abutment rod on the parts to be processed by rotating the abutment rod.
[0018] Preferably, each of the driving components includes a driving member and a displacement block, and one end of each clamping rack away from the placement rack is rotatably connected to the corresponding displacement block, and the driving member is used to drive the displacement block to slide along the height direction of the mounting rack.
[0019] By adopting the above technical solution and specifically arranging the driving assembly, when the driving member drives the displacement block to slide upward, the displacement block can drive the clamping frame to move upward away from one end of the placement frame, thereby causing the clamping frame to rotate and bring the clamping frame closer to one end of the placement frame. Driven by the rotating frame, the parts to be processed are clamped, thereby ensuring the clamping effect of the parts to be processed and facilitating the driving of the clamping frame by relevant personnel.
[0020] Preferably, the number of the placement racks is set to be several, and clamping mechanisms are provided on opposite sides of each of the placement racks.
[0021] By adopting the above-mentioned technical scheme, a plurality of placement racks are set up, so that a plurality of parts to be processed can be placed on the mounting rack, so that the processing equipment of the present application can be used to process a plurality of parts, thereby improving the work efficiency of the processing equipment of the present application, and further increasing the practicality and use effect of the present application.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The arrangement of the placement rack and the clamping mechanism enables smaller parts to be embedded on the top of the placement rack, thereby realizing the positioning and auxiliary fixation of smaller parts. At the same time, the end of the clamping rack close to the displacement rack can be driven by the driving assembly and the rotating rack to abut against the top of the part to be processed, thereby realizing the clamping and fixation of smaller parts, effectively reducing the probability of shaking or offsetting of smaller parts when being clamped, and ensuring the clamping effect of the outer wall end of the smaller parts;
[0024] 2. The arrangement of the abutment rod enables the bottom end of the abutment rod to abut against the top end of the part to be processed, thereby achieving the fixation of the part to be processed with the cooperation of the placement rack. At the same time, the abutment rod can also abut against the end of the surface of the smaller part and be located outside the area to be processed on the smaller part, thereby ensuring the clamping effect on the end of the outer wall of the smaller part. In addition, relevant personnel can also change the distance between the abutment rod and the bottom wall of the clamping rack by rotating the abutment rod, so that the abutment rod can abut against parts to be processed of different thicknesses, thereby increasing the scope of application and practicality of the present application.
[0025] 3. The connection frame and the additional frame are arranged so that when one end of the clamping frame is driven by the driving assembly and approaches the part to be processed, after the additional frame abuts against the surface of the part to be processed, the additional frame can slide relative to the connection frame, so that the elastic member is compressed, and the elastic force applied by the elastic member to the additional frame becomes larger, thereby changing the abutment force of the additional frame on the part to be processed, changing the clamping effect of the part to be processed, thereby reducing the probability of the surface of the part to be processed being damaged due to excessive pressure applied by the additional frame on the part to be processed, and effectively protecting the part to be processed.

DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] Embodiment 1:
[0033] Embodiment 1 of the present application discloses a plane processing tool. Figure 1 and Figure 2 The plane processing jig includes a mounting frame 1, on which a placing frame 2 is also provided. The placing frame 2 is used for embedding parts to be processed. Clamping mechanisms 3 are provided on opposite sides of the placing frame 2. Each clamping mechanism 3 includes a rotating frame 31, a clamping frame 32 and a driving assembly 33. One end of the rotating frame 31 is rotatably connected to the mounting frame 1, and the other end of the rotating frame 31 is rotatably connected to the clamping frame 32. The driving assembly 33 is used to drive the corresponding clamping frame 32 to move away from one end of the placing frame 2, and to rotate the clamping frame 32 and the corresponding rotating frame 31. The bottom of each clamping frame 32 close to one end of the placing frame 2 is used to abut against the top of the part to be processed.
[0034] Reference Figure 1 and Figure 2 , the number of the placing racks 2 on the mounting rack 1 is set to be several. In the embodiment of the present application, the placing racks 2 are set to be three, and are evenly arranged along the length direction of the mounting rack 1. The bottom end of each placing rack 2 is fixedly connected to the mounting rack 1. Each placing rack 2 is provided with a clamping mechanism 3 on both opposite sides along the width direction of the mounting rack 1. A placing groove 21 for embedding and placing the parts to be processed is provided on the top of each placing rack 2, and the parts to be processed are embedded in the placing groove 21.
[0035] Reference Figure 1 and Figure 2 Each driving assembly 33 includes a driving member 331 and a displacement block 332. In the embodiment of the present application, the driving member 331 is set as a cylinder, the cylinder body of which is fixedly mounted on the top wall of the mounting frame 1 by bolts, the piston rod of the cylinder is vertically arranged upward, and the displacement block 332 is fixedly mounted on the top of the piston rod of the corresponding cylinder. In the embodiment of the present application, the number of rotating frames 31 in each clamping mechanism 3 is set to two, and the two rotating frames 31 are respectively located on both sides of the corresponding clamping frame 32 along the length direction of the mounting frame 1.
[0036] Reference Figure 1 and Figure 2 , each cylinder is provided with an extension frame 34 at one end close to the corresponding placement frame 2, and the extension frame 34 is fixedly connected to the top of the corresponding cylinder body by bolts. One end of each rotating frame 31 is rotationally connected to the extension frame 34 through a pin shaft to realize the rotation connection between the rotating frame 31 and the mounting frame 1. The top of each rotating frame 31 is rotationally connected to the middle part of the corresponding clamping frame 32 along its own length direction through a pin shaft. The end of each rotating frame 31 away from the placement frame 2 is rotationally connected to the corresponding displacement block 332 through a pin shaft.
[0037] Reference Figure 1 and Figure 2, in the initial state, that is, when the part to be processed is not placed in the placement slot 21, the clamping frame 32 is at one end away from the driving member 331 and is located at the top of its own displacement trajectory, and the piston rod of the driving member 331 is in a retracted state. When the piston rod of the driving member 331 extends upward, the driving member 331 drives the displacement block 332 to move upward. At this time, the clamping frame 32 rotates relative to the displacement block 332, and under the action of the rotating frame 31, the top of the clamping frame 32 rotates downward and approaches the corresponding placement frame 2. In this process, the rotating frame 31 rotates relative to the extension frame 34 and the clamping frame 32.
[0038] Reference Figure 1 and Figure 2 Each clamping rack 32 is provided with an abutting rod 4 at one end close to the placement rack 2, and an external thread is provided on the side wall of the abutting rod 4, and the top of the abutting rod 4 is higher than the corresponding clamping rack 32. The bottom end of the abutting rod 4 is extended downward and passes through the bottom end of the corresponding clamping rack 32, and is threadedly connected with the corresponding clamping rack 32, so that relevant personnel can adjust the height of the bottom end of the abutting rod 4. The bottom end of the abutting rod 4 abuts against the top end of the part to be processed on the placement rack 2.
[0039] Reference Figure 1 and Figure 2 Two fixing nuts 41 are provided on each abutment rod 4. The two fixing nuts 41 are respectively located on the upper and lower sides of the clamping frame 32 and abut against the outer wall of the clamping frame 32. Each fixing nut 41 is threadedly connected to the corresponding abutment rod 4 to lock the abutment rod 4.
[0040] The implementation principle of a plane processing jig in Example 1 of the present application is as follows: when in use, place the part to be processed in the placement slot 21 on the placement rack 2, then loosen the fixing nut 41, and then rotate the abutment rod 4 to adjust the length of the bottom end of the abutment rod 4 extending relative to the bottom wall of the clamping rack 32. Then, control the piston rod of the driving member 331 to extend, at which time the clamping rack 32 rotates relative to the displacement block 332, and under the action of the rotating rack 31, the top of the clamping rack 32 rotates downward and approaches the corresponding placement rack 2. In this process, the rotating rack 31 rotates relative to the extension rack 34 and the clamping rack 32, and finally makes the bottom end of the abutment rod 4 abut against the top of the part to be processed in the placement slot 21.
[0041] Embodiment 2:
[0042] The difference between the second embodiment of the present application and the first embodiment is that: Figure 3 and Figure 4Each abutting rod 4 is provided with a connecting frame 5, and the bottom end of each abutting rod 4 extends into the top end of the corresponding connecting frame 5 and is rotatably connected to the corresponding connecting frame 5 through a bearing. Each connecting frame 5 is slidably connected to the corresponding clamping frame 32, and the sliding direction of each connecting frame 5 is the height direction of the corresponding driving member 331.
[0043] Reference Figure 3 and Figure 4 , each connecting frame 5 is provided with an additional frame 6, and a sliding portion 61 extends upward from the top of each additional frame 6 to increase the stability of the additional frame 6 when sliding. In the embodiment of the present application, the number of the sliding portions 61 is set to two. Each sliding portion 61 is integrally formed with the corresponding additional frame 6, and the top of each sliding portion 61 passes through the corresponding connecting frame 5 and is slidably connected to the corresponding connecting frame 5. The sliding direction of each sliding portion 61 relative to the connecting frame 5 is the height direction of the driving member 331.
[0044] Reference Figure 3 and Figure 4 The cross-sectional area of one end of each sliding portion 61 passing through the connecting frame 5 is larger than the cross-sectional area of the rest of the sliding portion 61 , so as to limit the sliding portion 61 and reduce the probability of the sliding portion 61 escaping from the connecting frame 5 .
[0045] Reference Figure 3 and Figure 4 , each sliding portion 61 is sleeved with an elastic member 7 for continuously applying elastic force to the additional frame 6. In the embodiment of the present application, the elastic member 7 is configured as a pressure spring, each of which is located between the corresponding additional frame 6 and the connecting frame 5, the top of each pressure spring abuts against the bottom of the connecting frame 5, and the bottom of each pressure spring abuts against the top of the additional frame 6.
[0046] Reference Figure 3 and Figure 4 In the embodiment of the present application, the bottom end of each additional frame 6 is hemispherical. An elastic sleeve 8 is sleeved on the bottom end of each additional frame 6. In the embodiment of the present application, the elastic sleeve 8 is made of rubber. Each elastic sleeve 8 is fixedly connected to the corresponding additional frame 6 by gluing.
[0047] The implementation principle of the plane processing jig of Example 2 of the present application is as follows: during the downward rotation of the end of the placement frame 2 away from the driving member 331, the elastic sleeve 8 at the bottom of the additional frame 6 gradually abuts against the top of the part to be processed. When the elastic sleeve 8 abuts against the top of the part to be processed, the placement frame 2 continues to move, and at this time, the additional frame 6 slides relative to the connecting frame 5, so that the elastic member 7 is compressed, increasing the elastic sleeve 8 at the bottom of the additional frame 6 and the abutting force on the part to be processed.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
